Answer:

x= 2

Step-by-step explanation:

y = 7 means it is parallel to the x axis . so the perpendicular line is to be parallel yo the y axis. .

so the equation is to be like x = c

but it is passing (2,13)

so the equation is

x= 2

Ounces would be in the denominator of your ratio.

Converting ounces to pounds you would simply divide by 16 :)

Have a great rest of your day! Good luck!

QUESTION 3 [10 MARKS] A bakery finds that the price they can sell cakes is given by the function p = 580 − 10x where x is the nu

Harman [31]

Answer:

(a)Revenue function, $R(x)=580x-x^2$

Marginal Revenue function, R'(x)=580-2x

(b)Fixed cost =900 .

Marginal Cost Function=300+50x

(c)Profit, $P(x)=-35x^2+280x-900$

(d)x=4

Step-by-step explanation:

Part A

Price Function $= 580 - 10x$

The revenue function

$R(x)=x\cdot (580-10x)\\R(x)=580x-x^2$

The marginal revenue function

$\dfrac{dR}{dx}= \dfrac{d}{dx}(R(x))=\dfrac{d}{dx}(580x-x^2)=580-2x\\R'(x)=580-2x$

Part B

(Fixed Cost)

The total cost function of the company is given by $c=(30+5x)^2$

We expand the expression

$(30+5x)^2=(30+5x)(30+5x)=900+300x+25x^2$

Therefore, the fixed cost is 900 .

Marginal Cost Function

If $c=900+300x+25x^2$

Marginal Cost Function, $\frac{dc}{dx}= (900+300x+25x^2)'=300+50x$

Part C

Profit Function

Profit=Revenue -Total cost

$580x-10x^2-(900+300x+25x^2)\\580x-10x^2-900-300x-25x^2\\$Profit,P(x)=-35x^2+280x-900$

Part D

To maximize profit, we find the derivative of the profit function, equate it to zero and solve for x.

$P(x)=-35x^2+280x-900\\P'(x)=-70x+280\\-70x+280=0\\-70x=-280\\$Divide both sides by -70\\x=4$

The number of cakes that maximizes profit is 4.

What is the equation of a line that has an x-intercept of -4 and a y-intercept of 8 ?

podryga [215]

Answer:

y=2/-1+8

Step-by-step explanation:

-4= (-4,0) -4=x1 0=y1, 8= (0,8) 0=x2 8=y2
formula is, y2-y1/x2-x1
8-0/0-4=8/-4=4/-2= 2/-1
2/-1 is the slope or (m), use (-4,0) or (0,8) i used (0,8) because its easier.
(0,8), 0=x1 8=y1
formula is y-y1=m(x-x1)
y-8=2/-1(x-0) ---->distribute
y-8=2/-1x-0 --->get y alone

+8 +8

so the answer is y=2/-1+8

Given the function g(x) = 6(4)x, Section A is from x = 0 to x = 1 and Section B is from x = 2 to x = 3.

Mademuasel [1]

We are given the function:

g(x) = 6 (4)^x

Part A.

To get the average rate of change, we use the formula:

average rate of change = [g(x2) – g(x1)] / (x2 – x1)

Section A:

average rate of change = [6 (4)^1 – 6 (4)^0] / (1 – 0) = 18

Section B:

average rate of change = [6 (4)^3 – 6 (4)^2] / (3 – 2) = 288

Part B.

288 / 18 = 16

Therefore the average rate of change of Section B is 16 times greater than in Section A.

The average rate of change is greater between x = 2 to x = 3 than between x = 1 and x = 0 because an exponential function's rate of change increases with increasing x (not constant).
