Identifying rate of chang

trasher [3.6K]

There is no question content here but I can still help just add a picture

If you want to know how to identify the rate of change here's how.

If we use only the beginning and ending data, we would be finding the average rate of change over the specified period of time. To find the average rate of change, we divide the change in the output value by the change in the input value.

Hope this helps sum!

A company produces two types of solar panels per year: x thousand of type A and y thousand of type B. The revenue and cost equat

jolli1 [7]

Answer:

7000 type A
6000 type B

Step-by-step explanation:

We assume your equations are intended to be ...

$C(x,y)=x^2-2xy+9y^2+3x-87y-6\\R(x,y)=5x+7y$

Then the profit equation is ...

$P(x,y)=R(x,y)-C(x,y)=5x+7y-x^2+2xy-9y^2-3x+87y+6\\=-x^2+2xy-9y^2+2x+94y+6$

The partial derivatives of profit with respect to x and y are zero when profit is maximized.

∂P/∂x = 0 = -2x +2y +2

∂P/∂y = 0 = 2x -18y +94

Simplifying, these equations are ...

y = x -1
x -9y = -47

Substituting the first into the second gives ...

x -9(x -1) = -47

-8x = -56

x = 7

y = 7 -1 = 6

The company will maximize profit by selling 7000 panels of type A and 6000 panels of type B.

Simplify this expression. 12x2(3x4 − 2x)

musickatia [10]

Answer:

$36*x^6-24*x^3$

Step-by-step explanation:

We can simplify the expressio using the product rule. The exponents will add up when multiplied with each other:

$=12*x^2*(3*x^4-2*x)$

$=12*3*x^(2+4)-12*2*x^(2+1)$

$=36*x^(6)-24*x^(3)$

The answer is B

$36*x^6-24*x^3$
