Answer:
If parabolas open down, then their vertices are at a maximum point, whereas if parabolas open up, their vertices are at a minimum point.
I hope this was the answer you were looking for, and as always, I am joyous to assist anyone at any time.
To find the max/min of a function, find where the function's first derivative is zero. Check those points with the second derivative: a positive value indicates a minimum and a negative value indicates a maximum.
Explanation:To find the maximum or minimum of a function, you should first understand that these points occur where the derivative of the function is zero, which corresponds to the points with a flat tangent line (no slope). To derive this, differentiate the function and mark all the points where the derivative equals zero. These are potential maximum or minimum points, also known as extrema.
However, it's also important to note that a zero derivative does not always mean a maximum or minimum is present. To confirm this, you need to perform the second-derivative test. If after differentiating the first derivative you get a positive value, the original function has a minimum at that point. If it's negative, the function has a maximum.
For example, let's take the function f(x) = x². The derivative f'(x) = 2x, and setting this to zero gives us x = 0 as the only point whose derivative equals zero. Further, the second derivative, f''(x), equals 2, which is positive, indicating a minimum occurs at x = 0.

A computer manufacturer built a new facility for assembling computers. There were construction and new equipment costs. The company paid for these costs and made combined profits of $80 million after 4 years, as shown in the graph
The question revolves around understanding the concepts of fixed costs, marginal costs, and economies of scale in the context of a computer manufacturing company. The company's ability to make substantial profits over a period of four years marks an effective management of these costs and leveraging economies of scale.
Explanation:The computer company's scenario primarily involves understanding the concept of fixed costs and marginal costs in a business context. The fixed cost noted here is $250, which remains constant irrespective of the number of computers produced. The marginal cost, on the other hand, is variable depending on the volume of production.
For example, the company's marginal cost for producing computers is $700 for the first one, $250 for the second, and so on. The total cost is obtained by adding the fixed cost and the total variable (marginal) costs. Understanding these costs is critically important for the company to make decisions about pricing its products to achieve desired profit margins.
It means that if the company managed to make profits of $80 million after 4 years, they have effectively managed their fixed and variable costs and priced their computers profitably. In this example, by leveraging the economies of scale, that is, an advantage that companies gain when production becomes efficient with the increasing scale of output, the company has managed to reduce the average cost of production and increase profits.

using the quadradic formula to solve x^2=5-x, what are the values of x
Answer:

-1+-square root od=f 1^2 - 4x1x(-5) / 2x1 = -1+- square root of 21 (add numbers together) / 2
then solve the formula with a plus sign instead of +- then and solve the formula with a - this time and you should get x1 = 2.79129, x2 = 1.79129, or -1 +square root of 21 (add numbers together) / 2 and -1 - square root of 21 (add numbers together) / 2
For this case we must solve the following equation:
[tex]x ^ 2 = 5-x[/tex]
By manipulating algebraically we have:
[tex]x ^ 2 + x-5 = 0[/tex]
The quadratic formula is given by:
[tex]x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}[/tex]
We have to:
[tex]a = 1\\b = 1\\c = -5[/tex]
Substituting we have:
[tex]x = \frac {-1 \pm \sqrt {1 ^ 2-4 (1) (- 5)}} {2 (1)}\\x = \frac {-1 \pm \sqrt {1 + 20}} {2}\\x = \frac {-1 \pm \sqrt {21}} {2}[/tex]
So, we have two roots:
[tex]x_ {1} = \frac {-1+ \sqrt {21}} {2} = 1,7913\\x_ {2} = \frac {-1- \sqrt {21}} {2} = - 2.7913[/tex]

Answer with step-by-step explanation:
We are given that at one farmer’s market, bananas cost $0.80 per pound while at another market, bananas are sold in 5 pound bags for $4.50 per bag.
We are to explain how to find the better buy.
For the first market, the rate of bananas is given per pound but for the other market, the rate is given for a 5 pound bag so we will find the rate of bananas per pound to compare the rates of both markets.
One pound of bananas at 2nd market = 4.50/5 = $0.9
Therefore, getting bananas from the first market at $0.80 per pound is a better buy.

Arnold invested $64,000, some at 5.5% interest and the rest at 9%. How much did he invest at each rate if he received $4,500 in interest in one year?
Answer:
The amount invested at 5.5% was $36,000 and the amount invested at 9% was $28,000
Step-by-step explanation:
we know that
The simple interest formula is equal to
[tex]I=P(rt)[/tex]
where
I is the Final Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
Let
x -----> the amount invested at 5.5%
(64,000-x) -----> the amount invested at 9%
in this problem we have
[tex]t=1\ years\\I=\$4,500\\ P=\$64,000\\r1=0.055\\P1=\$x\\P2=\$64,000-\$x\\r2=0.09[/tex]
so
[tex]I=P1(r1t)+P2(r2t)[/tex]
substitute the given values
[tex]4,500=x(0.055*1)+(64,000-x)(0.09*1)[/tex]
[tex]4,500=0.055x+5,760-0.09x[/tex]
[tex]0.09x-0.055x=5760-4,500[/tex]
[tex]0.035x=1,260[/tex]
[tex]x=\$36,000[/tex]
[tex]64,000-x=64,000-36,000=\$28,000[/tex]
therefore
The amount invested at 5.5% was $36,000 and the amount invested at 9% was $28,000
Find the area of a triangle with legs that are: 15 mm, 10 mm, and 20 mm.
Answer:
Area = [tex]\frac{75}{4} \sqrt{15} sq mm[/tex]
Step-by-step explanation:
Here we are given with all the sides of the triangle , and we are asked to find the area of it. we will use Heron's Formula to find the area. The formula is as under
Area [tex]= \sqrt{s\times (s-a) \times (s-b) \times (s-c)}[/tex]
Where [tex]s= \frac{a+b+c}{2}[/tex]
Where a , b and c are the three sides of the triangle
a=15 , b=10 and c=20
Substituting those values in the two formula one by one we get
[tex]s=\frac{15+10+20}{2}[/tex]
[tex]s=\frac{45}{2}[/tex]
now putting this value of s in main formula we get
Area= [tex]\sqrt{s\times (s-a) \times (s-b) \times (s-c)}[/tex]
Area = [tex]\sqrt{\frac{45}{2} \times (\frac{45}{2}-15) \times (\frac{45}{2}-10) \times (\frac{45}{2}-20)}[/tex]
Area = [tex]\sqrt{\frac{45}{2} \times (\frac{45-30}{2}) \times (\frac{45-20}{2}-) \times (\frac{45-40}{2})}[/tex]
Area = [tex]\sqrt{\frac{45}{2} \times (\frac{15}{2}) \times (\frac{25}{2}) \times (\frac{5}{2})}[/tex]
Area = [tex]\sqrt{\frac{45}{2} \times (\frac{15}{2}) \times (\frac{20}{2}-) \times (\frac{5}{2})}[/tex]
Area = [tex]\frac{1}{4} \sqrt{45 \times 15 \times 25 \times 5}[/tex]
Area = [tex]\frac{1}{4} \sqrt{45 \times 15 \times 25 \times 5}[/tex]
Area = [tex]\frac{1}{4} \sqrt{9 \times 5 \times 5 \times 3 \times 25 \times 5}[/tex]
Area = [tex]\frac{3\times 5 \times 5}{4} \sqrt{3 \times5}[/tex]
Area = [tex]\frac{75}{4} \sqrt{15}[/tex]

Scalene triangleIt is a triangle that with sides and angles that are not equal.Area of a scalene triangle depends on the features of the triangle given.For example;
Sine FormulaArea of a triangle = 1/2 ab sin θ, when given two sides of the triangle and the angle between themHeron's formulaArea of a triangle = [tex]s\sqrt{s(s-a)(s-b)(s-c)}[/tex] when given all the sides of the triangle. where [tex]s =\frac{(a+b+c)}{2}[/tex]In this case we are given, a = 15 mm, b = 10 mm, c = 20 mm
Therefore, we use the Heron's formula;
Area= [tex]s\sqrt{s(s-a)(s-b)(s-c)}[/tex]
[tex]s =\frac{(a+b+c)}{2}[/tex]
[tex]s= \frac{(15+10+20)}{2} \\s= 22.5[/tex]
Therefore;
Area = [tex]s\sqrt{s(s-a)(s-b)(s-c)}[/tex]
= [tex]22.5\sqrt{12.5(12.5-15)(22.5-10)(22.5-20)}[/tex]
=[tex]\sqrt{22.5(7.5)(12.5)(2.5)} \\\sqrt{5273.4375}[/tex]

What is the solution to the equation g^(x-2)=27
Answer:
First problem: Solving for g.
[tex]g=27^{\frac{1}{x-2}}[/tex]
Second problem: Solving for x.
[tex]x=\log_g(27)+2[/tex]
Third problem: Assuming g is 9 while solving for x.
[tex]x=3.5[/tex]
Step-by-step explanation:
First problem: Solving for g.
[tex]g^{x-2}=27[/tex]
Raise both sides by 1/(x-2).
[tex](g^{x-2})^{\frac{1}{x-2}}=27^{\frac{1}{x-2}}[/tex]
[tex]g^{1}=27^{\frac{1}{x-2}}[/tex]
[tex]g=27^{\frac{1}{x-2}}[/tex]
Second problem: Solving for x.
[tex]g^{x-2}=27[/tex]
x is in the exponent so we have to convert to logarithm form since we desire to solve for it:
[tex]\log_g(27)=x-2[/tex]
Add 2 on both sides:
[tex]\log_g(27)+2=x[/tex]
[tex]x=\log_g(27)+2[/tex]
Third problem: Assuming g is 9 while solving for x.
[tex]9^{x-2}=27[/tex]
I'm going to solve this in a different way than I did above but you could solve it exactly the way I did for x when 9 was g.
I'm going to write both 9 and 27 as 3 to some power.
9=3^2 while 27=3^3.
[tex](3^2)^{x-2}=3^3[/tex]
[tex]3^{2x-4}=3^3[/tex]
Since both bases are the same on both sides, we need the exponents to be the same:
[tex]2x-4=3[/tex]
Add 4 on both sides:
[tex]2x=7[/tex]
Divide both sides by 2:
[tex]x=\frac{7}{2}[/tex]
[tex]x=3.5[/tex]
Now earlier for x in terms of g we got:
[tex]x=\log_g(27)+2[/tex]
I we input 9 in place of g and put it into our calculator or use some tricks without the calculator to compute we should get 3.5 as the answer like we did above when g was 9.
[tex]x=\log_9(27)+2[/tex]
[tex]x=\frac{3}{2}+2[/tex]
[tex]x=1.5+2[/tex]
[tex]x=3.5[/tex]

What is 12x - 4y = -8 written in slope-intercept form?
y = 3x+2
y= 3x-2
y = 12x-8
y=-12X-8
Hey there!
Isolate the y variable by subtracting 12x in both sides:
-4y = -12x - 8
To solve for y divide -4 in both sides
y = 3x + 2
Our answer would be y = 3x + 2
Answer:
y = 3x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 12x - 4y = - 8 into this form
Subtract 12x from both sides
- 4y = - 12x - 8 ( divide all terms by - 4 )
y = 3x + 2 ← in slope- intercept form

Answer:
y = - [tex]\frac{1}{4}[/tex] x² + 3
Step-by-step explanation:
Any point (x, y) on the parabola is equidistant from the focus and directrix.
Using the distance formula
[tex]\sqrt{(x-0)^2+(y-2)^2}[/tex] = | y - 4 |, that is
[tex]\sqrt{x^2+(y-2)^2}[/tex] = | y - 4 |
Squaring both sides
x² + (y - 2)² = (y - 4)² ← distribute parenthesis
x² + y² - 4y + 4 = y² - 8y + 16 ( subtract y² - 8y from both sides )
x² + 4y + 4 = 16 ( subtract x² + 4 from both sides )
4y = - x² + 12 ( divide both sides by 4 )
y = - [tex]\frac{1}{4}[/tex] x² + 3

Step-by-step explanation:
Solve the equation in the innermost parentheses first that means solving 4+1 =5
The next step would be subtracting 9 from five which gives you 4
Next multiply 3 to 4 which gives you 12
Then multiply 5 with 12 which equals 60
Now you have the equation 60+20/4*2
Solve the division and multiplication part of the equation first because of the rule pemdas which shows multiplication comes before addition
First divide 20/4 which gives you 5 then multiply with 2 which gives you ten

how many solutions does the following equation have?3(x+5)=−4x+8
Answer:
1
Step-by-step explanation:
Solve the equation for x:
3(x + 5) = -4x + 8
Distribute.
3x + 15 = -4x + 8
Combine like terms.
3x + 15 = -4x + 8
+4x +4x
7x + 15 = 8
-15 -15
7x = -7
Divide both sides by 7.
x = -1
The following equation has one solution, x = -1.
Answer:
1 solution, x = -1.
Step-by-step explanation:
3(x + 5 )= −4x + 8
3x + 15 = -4x + 8
3x + 4x = 8 - 15
7x = -7
x = -1.

Find the circumference given the area = 50.3 m². Use 3.14 for π as necessary.
The circumference of a circle with an area of 50.3 m² is 25.12 m.
Further Explanation Area Area is a measure of how much space is occupied by a given shape.Area of a substance is determined by the type of shape in question.For example;
Area of a rectangle is given by; Length multiplied by widthArea of a triangle = 1/2 x base x heightArea of a circle = πr². where r is the radius of a circle,Area of a square = S², Where s is the side of the square.etc.Perimeter Perimeter is defined as the distance along a two dimension shape. Perimeter of different shapes is given by different formulasFor example;
The perimeter of a rectangle = 2(length+width)The perimeter of a triangle = a+b+c; where a, b and c are the sides of the triangle. etc.The Circumference of a circle = 2πr , where r is the radius of the circleIn this case;
The Area of a circle = 50.3 m²
π = 3.14
But; Area of a circle = πr²
Therefore;
3.14r²= 50.3 m²
r² = 50.3/3.14
=16.019
r = √16.019
= 4.0023
≈ 4.00
But;
Circumference of a circle is given by 2πr
Thus;
Circumference = 2 × 3.14 × 4.00
= 25.12 m
