Find the difference. express your answer in simplest form. (2s/s^2-4s+4) - (4/s^2-4s+4)
Answers
[tex] \frac{2s}{s^2-4s+4} -( \frac{4}{s^2-4s+4} )[/tex]
[tex]\frac{2s}{s^2-4s+4} -\frac{4}{s^2-4s+4}= \frac{2s-4}{s^2-4s+4} [/tex]
Now we can factor both numerator and denominator and simplify:
[tex]\frac{2s-4}{s^2-4s+4} = \frac{2(s-2)}{(s-2)^2} = \frac{2}{s-2} [/tex]
We can conclude that the difference in simplest form is: [tex] \frac{2}{s-2} [/tex]

four times the sum of a number and 2/3 is 16/3. find the number. express your answer as a fraction in simplest form
Answers
sum= addition
is= equal sign
x= a number
4 times x plus 2/3 equals 16/3.
4x + 2/3= 16/3
subtract 2/3 from both sides
4x= 14/3
divide both sides by 4
x= 14/3 ÷ 4
to divide fractions, multiply by reciprocal/inverse of 4
x= 14/3 * 1/4
multiply numerators (top); multiply denominators (bottom)
x= (14*1)/(3*4)
x= 14/12
simplify by 2
x= 7/6

The measure of the side length of the right triangle is 20.
What is the measure of the missing side length?A tangent makes an angle of 90 degrees with the radius of a circle.
Therefore, the triangle formed is a right triangle.
From the diagram:
Leg 1 = 12
Leg 2 = 16
Hypotenuse =?
To find the hypotenuse, we use the Pythagoras theorem:
(Hypotenuse)² = ( Leg 1 )² + ( Leg 2 )²
(Hypotenuse)² = ( 12 )² + ( 16 )²
(Hypotenuse)² = 144 + 256
(Hypotenuse)² = 400
Take the square roots of both sides:
Hypotenuse = √400
Hypotenuse = 20
Therefore, the side length measures 20 units.
Option C) 20 is the correct answer.

the initial number of bacteria in a culture is 12,000. the xulture doubles each day write an exponential functin to model the population Y of bacteria after X days
Answers
This equation is of the form y=a*bˣ, where a is the initial population and b is the rate that it increases by. In this problem, a = 12000 and b=2, since it doubles each time.
Answer:
[tex]Y = 12,000 \cdot (2)^X[/tex]
Step-by-step explanation:
The exponential function is given by:
[tex]y =a \cdot b^x[/tex]
where,
a is the initial values and b is the growth factor.
As per the statement:
The initial number of bacteria in a culture is 12,000.
⇒Number of bacteria initially(a) = 12,000
It is also given that the culture doubles each day.
⇒ growth factor [tex]b= 2[/tex]
We have to find the exponential function to model the population Y of bacteria after X days.
By definition of exponential function:
[tex]Y = 12,000 \cdot (2)^X[/tex]
where, x represents the days and Y is the population after X days.
Therefore, an exponential function to model the population is,
[tex]Y = 12,000 \cdot (2)^X[/tex]

4.2
5.4
Answers
The given function is y = 2x -1 which is of the form of a straight line with the form y = mx + c
now, we have been given that the value of x is 3.2 as it says input value is 3.2
we plug in x =3.2 in the equation
y = 2x -1
y = 2*3.2 -1
y = 6.4 -1
y = 5.4
So the value of y we get is 5.4
Answer = 5.4 (option D)

How much should they each get?
Eli-
Freda-
Geoff-
Answers
[tex]9+13+18=40[/tex]
The combined age of Eli, Freda, and Geoff is 40, so the denominator of each ratio will be 40.
Next, we are going to multiply the ratio between the age of the person and their combined age by £800:
For Eli: [tex] \frac{9}{40} *800=180[/tex]
For Freda: [tex] \frac{13}{40} *800=260[/tex]
For Geoff: [tex]\frac{18}{40} *800=360[/tex]
We can conclude that Eli will get £180, Freda will get £260, and Geoff will get £360.
Final answer:
Calculate how £800 should be divided among Eli, Freda, and Geoff based on their ages.
Explanation:
Ratio of ages: 9:13:18 = 9/40 : 13/40 : 18/40
Total amount: £800
Eli: £200
Freda: £290
Geoff: £410

Suppose you have $16,000 to invest in three stocks, A, B, and C. Stock A is a low-risk stock that has expected returns of 4%. Stock B is a medium-risk stock that has expected returns of 5%. Stock C is a high-risk stock that has expected returns of 6%. You want to invest at least $1,000 in each stock. To balance the risks, you decide to invest no more than $7,000 in stock C and to limit the amount invested in C to less than 4 times the amount invested in stock A. You also decide to invest less than twice as much in stock B as in stock A. How much should you invest in each stock to maximize your expected profit? Complete the constraints.
Answers
Answer:
Stock A: 1
Stock B: 1 and y=2
Stock C: 1, 7, 4
To maximize expected profit, you need to determine the amount to invest in stocks A, B, and C while considering the given constraints.
Explanation:To invest in each stock to maximize expected profit, we need to determine the amount to invest in stocks A, B, and C while considering the given constraints.
Let's denote the amount invested in stock A as x, in stock B as y, and in stock C as z.
The constraints are as follows:
At least $1,000 should be invested in each stock: x > $1,000, y > $1,000, z > $1,000No more than $7,000 should be invested in stock C: z < $7,000The amount invested in C should be less than 4 times the amount invested in A: z < 4xThe amount invested in B should be less than twice the amount invested in A: y < 2xTo maximize expected profit, we need to maximize the sum of the expected returns from each stock:
Expected profit = 0.04x + 0.05y + 0.06z
By solving the constraints and optimizing the expected profit function, we can find the optimal values for x, y, and z.

Answer:
0.8 and 1.1 are outliers of the given data set.
Step-by-step explanation:
The given data set is
5.8, 6.1, 4.9, 10.9, 0.8, 6.1, 7.4, 10.2, 1.1, 5.2, 5.9
Arrange the data set in ascending order
0.8, 1.1, 4.9, 5.2, 5.8, 5.9, 6.1, 6.1, 7.4, 10.2, 10.9
Divide the data in four equal parts.
(0.8, 1.1), 4.9,( 5.2, 5.8), 5.9,( 6.1, 6.1), 7.4, (10.2, 10.9)
From the above division we get,
[tex]Q_1=4.9[/tex]
[tex]Median=5.9[/tex]
[tex]Q_3=7.4[/tex]
The interquartile range of the data is
[tex]IQR=Q_3-Q_1[/tex]
[tex]IQR=7.4-4.9=2.5[/tex]
If all the data elements lies in the interval [Q₁-1.5(IQR),Q_3+1.5(IQR)], then the data set has no outliers.
[tex][Q_1-1.5(IQR),Q_3-1.5(IQR)]=[4.9-1.5(2.5),7.4-1.5(2.5)]=[1.15,11.15][/tex]
Since all the elements lie in the interval [1.15,11.15] except 0.8 and 1.1, therefore 0.8 and 1.1 are outliers.

The area of this rectangle is 5x2. What does the coefficient 5 mean in terms of the problem?
Answers
Answer: The length is 5 times the width
Step-by-step explanation:
Given: The area of rectangle = [tex]5x^2=(5x)(x)[/tex]
Here x must be a positive real number since it can not be negative.
Also for area of rectangle =[tex]length \times width[/tex]
And length is always greater than width of rectangle, therefore in the given expression 'x' must be width and '5x' must be length of rectangle .
[∵ for every positive x , 5x>x]
Hence, the coefficient 5 means the length is 5 times the width.

2x+3y=6
x-2y=10
Answers
The graph is shown in the attached image.
As we can note from the graph, the solution of the system of equations is indicated by the point of intersection between the two lines which is (6,-2)
Part (2):
The equations given are as follows:
2x + 3y = 6 ...........> equation I
x - 2y = 10
which can be rewritten as:
x = 2y + 10 ...........> equation II
Substitute with equation II in equation I and solve for y as follows:
2x + 3y = 6
2(2y+10) + 3y = 6
4y + 20 + 3y = 6
7y = 6 - 20
7y = -14
y = -2
Substitute with y in equation II to get x as follows:
x = 10 + 2y
x = 10 + 2(-2)
x = 10 - 4
x = 6
The solution is (6,-2)
Part (3):
The equations given are:
2x + 3y = 6 .............> equation I
x - 2y = 10 ...........> equation II
Multiply equation II by -2, this will give:
-2x + 4y = -20 ............> equation III
Add equation I and equation III as follows:
2x + 3y = 6
+ -2x + 4y = -20
.........................................
0x + 7y = -14
7y = -14
y = -2
Substitute with y in equation II to get x as follows:
x - 2y = 10
x - 2(-2) = 10
x + 4 = 10
x = 10 - 4
x = 6
The solution is (6,-2)

Answers
120(5)=W
600=W
600 Watts
The number of watts for a circuit with 120 volts and 5 amps is 600 watts.
Explanation:The formula for calculating the power in an electrical circuit is: Power (P) = Voltage (V) × Current (I).
To calculate the number of watts, we can substitute the given values into the formula:
Volts (V) = 120
Amps (I) = 5
Therefore, the number of watts (P) = 120 V × 5 A = 600 W.
