Y=x^2-4x+3
Answer:
Answer is below
Step-by-step explanation:
Use 3 as the y-intercept. Factor the equation to find the solutions
(x - 1) (x - 3) so 1 and 3 are the x-intercepts. The vertex of the graph is at (2,-1).
I also graphed the equation below.
If this answer is correct, please make me Brainliest!
The graph of [tex]y = x^2 - 4x + 3[/tex] is a parabola that opens upward with its vertex at (2, -1). It intersects the x-axis at x = 3 and x = 1 and the y-axis at y = 3.
How to graph this equationThe equation is [tex]y = x^2 - 4x + 3.[/tex]
Use the formula x = -b / (2a) to find the x-coordinate of the vertex. In this case, a = 1, b = -4.
x = -(-4) / (2*1)
= 4 / 2
= 2.
So, the x-coordinate of the vertex is 2.
Subtitute x = 2 into the equation:
[tex]y = (2)^2 - 4(2) + 3[/tex]
= 4 - 8 + 3
= -1.
The y-coordinate of the vertex is -1.
The vertex is at (2, -1).
The y-intercept, we will set x = 0 in the equation:
[tex]y = (0)^2 - 4(0) + 3[/tex]
= 0 - 0 + 3
= 3.
The get x-intercepts, we set y = 0 in the equation:
[tex]0 = x^2 - 4x + 3.[/tex]
(x - 3)(x - 1) = 0.
x = 3 or x = 1.
The x-intercepts are 3 and 1.
Now, we will plot the y-intercept and x-intercepts. The y-intercept is at (0, 3), and the x-intercepts are at (3, 0) and (1, 0).

-3(x+y)+4=7y
Solve for y
Answer: y= −3 /10 x + 2 /5
Step-by-step explanation:
Let's solve for y.
−3(x+y)+4=7y
Step 1: Add -7y to both sides.
−3x−3y+4+−7y=7y+−7y
−3x−10y+4=0
Step 2: Add 3x to both sides.
−3x−10y+4+3x=0+3x
−10y+4=3x
Step 3: Add -4 to both sides.
−10y+4+−4=3x+−4
−10y=3x−4
Step 4: Divide both sides by -10.
−10y /−10 = 3x−4 / −10
y= −3 /10 x+ 2 /5
In a right triangle ABC AB = 2cm BC =5cm and CA = square root of 29. what is angle A round to the nearest tenth
Answer:
68.2°
Step-by-step explanation:
AC is the longest side which means 90° is at B
SinA = BC/AC
sinA = 5/sqrt(29)
sinA = 0.9284766909
A = 68.19859051
A = 68.2°
To find the measure of angle A, we used the tangent function, which is the ratio of the side opposite the angle to the side adjacent to it. Using a calculator, the inverse tangent of the ratio BC/AB equals approximately 68.2 degrees.
Explanation:In order to solve for angle A in a right triangle, we can use the concept of trigonometry. Specifically, we'll use the tangent (tan) function, which in a right triangle is the ratio of the side opposite the angle to the side adjacent to it. Since angle A is between sides AB and AC, the tangent of A would be defined as tan(A) = opposite side/adjacent side = BC/AB = 5/2.
After calculating the ratio, typically, we would use a calculator to find the arctan or inverse tangent of this ratio, which should give the angle A in degrees. In this case, the arctan(5/2) equals about 68.2 degrees when rounded to the nearest tenth.

Justin did push-ups every weekday this week. He did 888 push-ups on Monday, 14 push-ups on Tuesday, 18 push-ups on Wednesday, 6 push-ups on Thursday, and 8 push-ups on Friday.
Find the mean number of push-ups.
Final answer:
To calculate the mean number of push-ups Justin did each weekday, add up the total push-ups for the week and divide by 5. Justin did a mean of 186.8 push-ups per day.
Explanation:
To find the mean number of push-ups Justin did each weekday, we need to add the number of push-ups he did each day and then divide by the number of days. The steps are:
Add the number of push-ups from Monday to Friday: 888 + 14 + 18 + 6 + 8.Calculate the sum: 888 + 14 + 18 + 6 + 8 = 934 push-ups.Divide the sum by the number of days (5 weekdays): 934 ÷ 5.Calculate the mean: 934 ÷ 5 = 186.8 push-ups.Therefore, the mean number of push-ups Justin did on a weekday is 186.8 push-ups.
Final answer:
The mean number of push-ups Justin did each weekday is calculated by adding the total push-ups for all the days and dividing by the number of days, resulting in 186.8 push-ups.
Explanation:
To find the mean number of push-ups, Justin did over the weekdays, you need to sum up the total push-ups and then divide by the number of days.
Add the number of push-ups for each day: 888 (Monday) + 14 (Tuesday) + 18 (Wednesday) + 6 (Thursday) + 8 (Friday) = 934 push-ups in total.
Divide the total number of push-ups by the number of days: 934 ÷ 5 days = 186.8 push-ups.
Therefore, the mean number of push-ups Justin did each weekday is 186.8 push-ups.

A sample of bacteria is being eradicated by an experimental procedure. The population is following a pattern of exponential decay and approaching a population of 0. If the sample begins with 500 bacteria and after 11 minutes there are 200 bacteria, after how many minutes will there be 50 bacteria remaining? Round your answer to the nearest whole number, and do not include units. answer
Answer:
There will be 50 bacteria remaining after 28 minutes.
Step-by-step explanation:
The exponential decay equation is
[tex]N=N_0e^{-rt}[/tex]
N= Number of bacteria after t minutes.
[tex]N_0[/tex] = Initial number of bacteria when t=0.
r= Rate of decay per minute
t= time is in minute.
The sample begins with 500 bacteria and after 11 minutes there are 200 bacteria.
N=200
[tex]N_0[/tex] = 500
t=11 minutes
r=?
[tex]N=N_0e^{-rt}[/tex]
[tex]\therefore 200=500e^{-11r}[/tex]
[tex]\Rightarrow e^{-11r}=\frac{200}{500}[/tex]
Taking ln both sides
[tex]\Rightarrow ln| e^{-11r}|=ln|\frac{2}{5}|[/tex]
[tex]\Rightarrow {-11r}=ln|\frac{2}{5}|[/tex]
[tex]\Rightarrow r}=\frac{ln|\frac{2}{5}|}{-11}[/tex]
To find the time when there will be 50 bacteria remaining, we plug N=50, [tex]N_0[/tex]= 500 and [tex]r}=\frac{ln|\frac{2}{5}|}{-11}[/tex] in exponential decay equation.
[tex]50=500e^{-\frac{ln|\frac25|}{-11}.t}[/tex]
[tex]\Rightarrow \frac{50}{500}=e^{\frac{ln|\frac25|}{11}.t}[/tex]
Taking ln both sides
[tex]\Rightarrow ln|\frac{50}{500}|=ln|e^{\frac{ln|\frac25|}{11}.t}|[/tex]
[tex]\Rightarrow ln|\frac{1}{10}|={\frac{ln|\frac25|}{11}.t}[/tex]
[tex]\Rightarrow t= \frac{ln|\frac{1}{10}|}{\frac{ln|\frac25|}{11}.}[/tex]
[tex]\Rightarrow t= \frac{11\times ln|\frac{1}{10}|}{{ln|\frac25|}}[/tex]
[tex]\Rightarrow t\approx 28[/tex] minutes
There will be 50 bacteria remaining after 28 minutes.
Final answer:
To solve this problem, we use the formula for exponential decay and solve for the time when there are 50 bacteria remaining.
Explanation:
To solve this problem, we can use the formula for exponential decay: A = A0 * e^(kt), where A is the final population, A0 is the initial population, e is Euler's number (approximately 2.71828), k is the decay constant, and t is the time in minutes.
First, let's determine the value of k. We know that after 11 minutes, the population is 200 bacteria, so we can substitute these values into the formula to solve for k: 200 = 500 * e^(11k).
Divide both sides of the equation by 500: 0.4 = e^(11k).
Take the natural logarithm of both sides to solve for k: ln(0.4) = 11k.
Divide both sides by 11 to find the value of k: k ≈ -0.07761.
Now we can use the formula to solve for t when there are 50 bacteria remaining: 50 = 500 * e^(-0.07761t).
Divide both sides by 500: 0.1 = e^(-0.07761t).
Take the natural logarithm of both sides to solve for t: ln(0.1) = -0.07761t.
Divide both sides by -0.07761 to find the value of t: t ≈ 13.857 minutes.
Therefore, after approximately 14 minutes (rounded to the nearest whole number), there will be 50 bacteria remaining.

Answer:
[tex]\frac{21}{4}[/tex]
Step-by-step explanation:
So to start, you need to make 3 [tex]\frac{3}{4\\}[/tex] into an improper fraction, which will give you [tex]\frac{15}{4}[/tex]. Then to make it easier, instead of dividing it by [tex]\frac{5}{7}[/tex], multiply it by the reciprocal ( [tex]\frac{7}{5}[/tex] )
Your new expression should look like this:
[tex]\frac{15}{4}[/tex] x [tex]\frac{7}{5}[/tex]
To make it even easier, you can simplify this expression even further. Looking at the numerators and denominators, we see that we have a 15 on top and a 5 on the bottom. Cross out the 5 and put a 1 in its place since 5 goes into 5 one time! Now we have to do it to the 15... Cross out the 15 and put a 3 since 5 goes into 15 three times!
Your simplified expression should look like this:
[tex]\frac{3}{4}[/tex] x [tex]\frac{7}{1}[/tex]
Now, just multiply the numerators and the denominators to get your final answer of
[tex]\frac{21}{4}[/tex]
Since you cannot simplify this anymore, that is your answer!!!

A delivery truck is transporting boxes of two sizes: large and small. The large boxes weigh 45 pounds each, and the small boxes weigh 25 pounds each. There are 120 boxes in all. If the truck is carrying a total of 4300 pounds in boxes, how many of each type of box is it carrying?
Answer:
50(115-y) + 25y = 4125 [from eq2]
5750 - 50y + 25y = 4125 [distribute]
5750 - 25y = 4125
-25y = -1625
y = 65 [divide both sides by (-25)]
There are 65 small boxes.
Put that value into either equation (now, which is easier?) to solve for x:
x = 115 - y
x = 115 - 65
x = 50
There are 50 large boxes.
- Mring0506
The required number of boxes that the truck contain is 55 small boxes and 65 large boxes.
Given that, the large boxes weigh 45 pounds each, and the small boxes weigh 25 pounds each. There are 120 boxes in all, the truck is carrying a total of 4300 pounds.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
here,
Let the number of large boxes will be l and the number of small boxed be s,
According to the question,
l + s = 120
l = 120 - s - - - - - (2)
Again,
45l + 25s = 4300
put l in the above equation,
45[120 - s] + 25s = 4300
5400 - 45s + 25s = 4300
20s = 1100
s = 1100/20
s = 55
Now,
l = 120 - 55
l = 65
Thus, the required number of boxes that the truck contain is 55 small boxes and 65 large boxes.

What the area of a circle with the diameter of 10 kilometers
Given:
Given that the diameter of the circle is 10 kilometers.
We need to determine the area of the circle.
Radius of the circle:
The radius of the circle can be determined using the formula,
[tex]r=\frac{d}{2}[/tex]
Substituting d = 10, we get;
[tex]r=\frac{10}{2}[/tex]
[tex]r=5[/tex]
Thus, the radius of the circle is 5 kilometers.
Area of the circle:
The area of the circle can be determined using the formula,
[tex]A=\pi r^2[/tex]
Substituting r = 5, we get;
[tex]A=(3.14)(5)^2[/tex]
[tex]A=(3.14)(25)[/tex]
[tex]A=78.5[/tex]
Thus, the area of the circle is 78.5 square kilometers.
Determine the radius, which is 5 kilometers, before calculating the area of a circle with a diameter of 10 kilometers. Next, find the area, or roughly 78.54 km², using the formula Area = π × (radius)².
How to Calculate a Circle's Area
You can use the following formula to get the area of a circle with a given diameter:
π × (radius)² equals area.
You must first determine the circle's radius. Half of the diameter is the radius. With a ten-kilometer diameter:Radius is equal to diameter / 2 (10 km / 2 = 5 km).Next, compute the area using the following formula:Area is equal to π × (radius)², π × (5 km)², and π × 25 km², or 78.54 km².Consequently, 78.54 km² is the approximate size of the circle with a diameter of 10 km.
When she woke in the morning Josie notices the temperature outside was -4.8*c. When she got home from school the temperature rose 15.6*c. What was the change in the temperature
Answer:
20.4°C
Step-by-step explanation:
Initial temperature 't1'= -4.8°C
Final temperature 't2'= 15.6°C
In order to find change in temperature, take the difference of above two temperatures. So,
Change in temperature 'ΔT' = t2 - t1
ΔT= 15.6 - (-4.8)
ΔT= 20.4 °C
Therefore, the change in temperature was 20.4°C
Wind power P from a turbine varies directly as the square of the length r of one ofits blades. Two common blade lengths for commercial wind turbines are 35m and 50m. When the blade length is 35m about 1.5 megawatt of power is produced under favorable conditions. How much power would be produced, under favorable conditions, by a turbine with 50m blades.
Answer:
3.06 megawatts
Step-by-step explanation:
Firstly, we write the proportionality equation.
wind power varies directly as the square of the length r of one of the blades;
P ∝ r^2
Let’s introduce a constant of proportionality k; This means;
P = kr^2
Now let’s calculate the value of k when 1.5 megawatts and r is 35m
1.5 mw = 35^2 * k
k = 1.5/35^2 = 1.5/1225 = 0.001224489796 MW/m^2
Now we want to calculate the amount of megawatts to be produced by a turbine with 50m blades.
That would be;
P = 0.001224489796 * 50^2 = 3.06 megawatts
Answer:
Step-by-step explanation:
If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding increase in the other variable. Also, a decrease in the value of one variable would cause a corresponding decrease in the other variable.
Given that P varies directly with r², if we introduce a constant of proportionality, k, the expression becomes
P = kr²
If P = 1.5 when r = 35, then
1.5 = k × 35²
k = 1.5/35² = 1.5/1225
Therefore, the direct variation function is
P = 1.5r²/1225
When r = 50, then
P = 1.5 × 50²/1225
P = 3.06 megawatt
One digit in each of these identification numbers of a postal money order is smudged. Can you recover the smudged digit, indicated by a Q, in each of these numbers? a) 493212Q0688 b) 850Q9103858 c) 2Q941007734 d) 66687Q03201
Answer:
a) Q = 0 or 9
b) Q = 5
c) Q = 7
d) Q = 8
Step-by-step explanation:
We assume the postal money order to be of the United State. A smudged digit is calculated using the following algorithm.
1. Add first 10 digits of 11-digit number.
2. Divide the sum of the 10 numbers by 9.
3.The remainder is the smudged digit.
4.The smudged digit is appended to the end of the ID number or anywhere in the number.
It is calculated as:
[tex]x_{11} = (x_{1} + x_{2} + x_{3} + x_{4} + x_{5} + x_{6} + x_{7} + x_{8} + x_{9} + x_{10} )mod 9[/tex]
a) 493212Q0688
[tex]8 = (4 + 9 + 3 + 2 + 1 + 2 + Q + 0 + 6 + 8) mod 9\\8 = (Q + 35) mod 9\\8 = Q mod 9 + 35 mod 9\\8 = Q mod 9 + 8\\Q mod 9 = 8 - 8\\Q mod 9 = 0\\Q = 0 or 9[/tex]
Therefore, Q is either 0 or 9.
b) 850Q9103858
[tex]8 = (8 + 5 + 0 + Q + 9 + 1 + 0 + 3 + 8 + 5) mod 9\\8 = (Q + 39) mod 9\\8 = Q mod 9 + 39 mod 9\\8 = Q mod 9 + 3\\Q mod 9 = 8 - 3\\Q mod 9 = 5\\Q = 5[/tex]
Therefore, Q is 5 because from Q mod 9 = 5, we have Q = 5 mod 9.
c) 2Q941007734
[tex]4 = (2 + Q + 9 + 4 + 1 + 0 + 0 + 7 + 7 + 3) mod 9\\4 = (Q + 33) mod 9\\4 = Q mod 9 + 33 mod 9\\4 = Q mod 9 + 6\\Q mod 9 = 4 - 6\\Q mod 9 = -2\\Q = -2 mod 9\\Q = 7[/tex]
Therefore, Q is 7 because we have to cancel out the negative sign by adding the modulo base (9) to the negative number: -2 + 9 = 7.
d) 66687Q03201
[tex]1 = (6 + 6 + 6 + 8 + 7 + Q + 0 + 3 + 2 + 0) mod 9\\1 = (Q + 38) mod 9\\1 = Q mod 9 + 38 mod 9\\1 = Q mod 9 + 2\\Q mod 9 = 1 - 2\\Q mod 9 = -1\\Q = -1 mod 9\\Q = 8[/tex]
Therefore, Q is 8 because we have to cancel out the negative sign by adding the modulo base (9) to the negative number: -1 + 9 = 8.
For the given postal money order scenarios, the smudged digit, Q, is determined as follows: Scenario a - either 0 or 9, Scenario b - 5, Scenario c - 5, and Scenario d - 3.
Let's analyze the given postal money order scenarios and determine the smudged digit, Q, using the provided algorithm:
Scenario a:
ID number: 493212Q0688
Sum of the first 10 digits: 4 + 9 + 3 + 2 + 1 + 2 + 0 + 6 + 8 + 8 = 43
43 divided by 9 equals 4 with a remainder of 7.
Therefore, the smudged digit, Q, is either 0 or 9.
Scenario b:
ID number: 850Q9103858
Sum of the first 10 digits: 8 + 5 + 0 + 9 + 1 + 0 + 3 + 8 + 5 + 8 = 47
47 divided by 9 equals 5 with a remainder of 2.
Therefore, the smudged digit, Q, is 5.
Scenario c:
ID number: 2Q941007734
Sum of the first 10 digits: 2 + 7 + 9 + 4 + 1 + 0 + 0 + 7 + 7 + 3 = 40
40 divided by 9 equals 4 with a remainder of 4.
To cancel out the negative sign in the remainder, we add the modulo base (9) to the negative number: -4 + 9 = 5.
Therefore, the smudged digit, Q, is 5.
Scenario d:
ID number: 66687Q03201
Sum of the first 10 digits: 6 + 6 + 6 + 8 + 7 + 0 + 3 + 2 + 0 + 1 = 33
33 divided by 9 equals 3 with a remainder of 6.
To cancel out the negative sign in the remainder, we add the modulo base (9) to the negative number: -6 + 9 = 3.
Therefore, the smudged digit, Q, is 3.

United Express, a national package delivery service, charges a base price for overnight delivery of packages weighing 1 pound or less and a surcharge for each additional pound (or fraction thereof). A customer is billed $29.00 for shipping a 7-pound package and $64.00 for a 27-pound package. Find the base price and the surcharge for each additional pound.
Answer:
The base charge = $18.5 and surcharge for each pound is = $1.75
Step-by-step explanation:
Solution:
- Denote:
Base charge = $x ...... For for Weight ≤ 1 lbs
Additional charge = $y / unit pounds
- We are given that the customer is billed $29.00 for shipping a 7-pound package. We can express this statement in terms of "x" and "y".
- The 1-pound out of 7 pounds will be charged with $x and remaining 6 additional pounds of weight will be charged "$y" for each unit of weight.
$x + ( 7 - 1 )*$y = $29.00 .... Eq1
- Similarly for a receipt of $64.00 for a 27-pound package. The 1-pound out of 27 pounds will be charged with $x and remaining 26 additional pounds of weight will be charged "$y" for each unit of weight.
$x + ( 27 - 1 )*$y = $64.00 .... Eq2
- Now solve the two equations simultaneously by subtracting Eq1 from Eq2:
(26 - 6 )*$y = $(64 - 29)
20*$y = $35
y = 1.75
$x = 29 - 6*1.75

Answer:
D. 4821 years
Step-by-step explanation:
A = A0e-0.000124t
A/A0 = e^-0.000124t
0.55 = e^-0.000124t
ln(0.55) = ln(e^-0.000124t)
ln(0.55) = -0.000124t × lne
t = ln(0.55)/-0.000124

Suppose that the revenue function for a certain product is given by R(x) = 17(2x + 1)−1 + 34x − 17 where x is in thousands of units and R is in thousands of dollars. (a) Find the marginal revenue (in thousands of dollars) when 2000 units are sold. $ 34 Incorrect: Your answer is incorrect. thousand (b) How does the revenue change when 2000 units are sold?
Answer:
Step-by-step explanation:
Given that:
R(x) = [tex]\frac{17}{2x+1}[/tex] + 34x − 17
As we know that derivative of revenue function is marginal revenue function .
We will use following rules of derivative
=> dR/ dx = [tex]\frac{-17*2}{(2x+1)^{2} } + 34[/tex]
=> R' (x) = [tex]\frac{-34}{(2x+1)^{2} } + 34[/tex]
=> R '(2000) = [tex]\frac{-34}{(2*2000+1)^{2} } + 34[/tex] = 34
The revenue when 2000 units are sold is:
R(2000) = [tex]\frac{17}{2*2000+1}[/tex] + 34*2000 − 17 = $69,783
The marginal revenue be "34" and revenue change be "$69,783".
Marginal revenue:The increase throughout income caused by the acquisition of one more unit of production, is a Marginal revenue. Although marginal income can stay unchanged at a predetermined interval, it's indeed subject to the regulations of decreasing returns as well as will ultimately slow as outcome level grows.
According to the question,
Revenue function,
R(x) = [tex]\frac{17}{2x+1}[/tex] + 34x - 17
Units sold = 2000
(a) The marginal revenue be:
→ [tex]\frac{dR}{dx}[/tex] = [tex]-\frac{17\times 2}{(2x+1)^2}[/tex] + 34
R'(x) = [tex]- \frac{34}{(2x+1)^2}[/tex] + 34
By substituting "x = 2000",
R'(2000) = [tex]- \frac{34}{(2\times 2000+1)^2}[/tex] + 34
= 34
(b) The revenue change be:
→ R(2000) = [tex]\frac{17}{2\times 2000+1}[/tex] + 34 × 2000 - 17
= 69,783 ($)
Thus the above response is appropriate.

Answer:
x=40
Step-by-step explanation:
Since a circle has a total of a 360 degree angle the equation is
(x+40)+(2x+60)+(3x+20)=360
to simplify this we can bring all the variables(x) together and the numbers together.
(x+2x+3x)+(40+60+20)=360
6x+120=360
6x=360-120
6x=240
6x/6=240/6
x=40
The sum of all the degrees in a circle is 360 degrees. Knowing this you can make a equation:
(x + 40) + (2x + 60) + (3x + 20) = 360
x + 40 + 2x + 60 + 3x + 20 = 360
(x + 2x + 3x) + (40 + 60 + 20) = 360
Now you must combine like terms This means the numbers with the same variables must be combined...
(x + 2x + 3x) + (40 + 60 + 20) = 360
x + 2x + 3x = 6x
(6x) + (40 + 60 + 20) = 360
Now combine the terms without variables (on the left side of the equation) together
(6x) + (40 + 60 + 20) = 360
40 + 60 + 20 = 120
(6x) + 120 = 360
Now we must isolate x. To do this first bring 120 to the right side by subtracting 120 to both sides (what you do on one side you must do to the other). Since 120 is being added on the left side, subtraction (the opposite of addition) will cancel it out (make it zero) from the left side and bring it over to the right side.
6x + 120 - 120 = 360 - 120
6x + 0 = 240
6x = 240
To further isolate x you must divide 6 to both sides. Since x is being multiplied by 6 you must divide 6 to both sides to make 6 one on the left side and bring it over to the right side
6x / 6 = 240 / 6
1x = 40
x = 40
Check:
(40 + 40) + (2(40) + 60) + (3(40) + 20)
(80) + (80 + 60) + (120 + 20)
80 + 140 + 140
360

through: (4, -2), parallel to y = - 3/4x - 4
Answer:
y = -3/4x +1
Step-by-step explanation:
Parallel lines have the same slope, so the slope of the line you want is -3/4. The point-slope form of the equation of a line is useful when you have this information:
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
y -(-2) = -3/4(x -4)
If you want slope-intercept form, you can rearrange this ...
y +2 = -3/4x +3
y = -3/4x +1 . . . . . . subtract 2 from both sides
A canned food manufacturer has its manufacturing plants in three locations across a state. Their product has to be transported to 3 central distribution centers, which in turn disperse the goods to 72 stores across the state. Which of the following is most likely to be the objective function in this scenario?a. A time-series plot
b. A network graph
c. A scatter chart
d. A contour plot
The objective function in this scenario is minimizing the cost of shipping goods from the plant to the store.
What is Linear Problem?The goal of the Linear Programming Problems (LPP) is to determine the best value for a given linear function. The ideal value may be either the highest or lowest value. The specified linear function is regarded as an objective function in this situation.
The most likely goal function, if we were to create a linear programme for this situation, would be to reduce the cost of shipping from the plants to the stores. This is important since it can become an expensive bottleneck.
Despite the fact that there are three factories and three stores, the costs will not be minimized if the same amount of goods are produced in each plant and carried to a specific store. In fact, the likelihood that each facility generates a distinct volume of items further exacerbates the issue.
Finding the optimal distribution of shipping commodities from each facility to each retailer is important as a result.
Hence, the objective function is minimizing the cost of shipping goods from the plant to the store.
