The height of a trapezoid is 6 in. And its area is 48 in2. One base of the trapezoid is 6 inches longer than the other base. Wha

omeli [17]

Answer:

5 in
11 in

Step-by-step explanation:

Let x represent the length of the shorter base in inches. Then the longer base has length x+6. The area of the trapezoid is given by the formula ...

A = (1/2)(b1 +b2)h

Filling in the values we know, we have ...

48 = (1/2)(x +(x+6))(6)

16 = 2x +6 . . . . . divide by 3

10 = 2x . . . . . . . . subtract 6

5 = x . . . . . . . . . . divide by 2

(x+6) = 11 . . . . . . find the longer base

The lengths of the bases are 5 inches and 11 inches. We found them by solving an equation relating area to base length.

Suppose that the dollar cost of producing x appliances is c(x)=1000+ 90x- 0.2x 2

Aleksandr [31]

Answer:

Step-by-step explanation:

Given that the dollar cost of producing x appliances is

$c(x)=1000+ 90x- 0.2x^2$

A) Average cost can be obtained by dividing c(x) by units = x

i.e. average cost = $\frac{1000}{x} +90-0.2x$

B) Marginal cost = dC/dx = $90-0.4x$

When x=140 marginal cost $= 90-0.4(140)\\=34$

C) We calculate

c(140) = $=1000+90(140)-0.2(140^2)\\\\=9680$

c(141) = $=1000+90(141)-0.2(141^2)\\\\\\=9713.80$

Marginal cost = difference = 33.80

Same as 34 shown in marginal cost.

Help please! Will give brainly! Explain how the equation y=x^2 differs from the equation y=x

ira [324]

Answer:

Below.

Step-by-step explanation:

$y=x^2$ is also $y = x*x$

It will differ for any x besides 1 and 0 because you're multiplying x by itself, which makes the answer greater.

But, it's the same for 1 and 0 because they equal each other when you square them.
