Help me with number 6 please!!!

1 answer:

4 0

Hints: in 5x+4y=32, let x= to obtain the y-intercept. y=8. This is the UPPER limit of the visible window. Next, let y= 0 in this same equation, to obtain the x-intercept. Answer: x=32/5. Since the 2 graphs extend beyond x=32/5, to the right, adopt x=7 as the RIGHT HAND limit of the visible window. Can you finish this problem?

-4x^4 - 3x^3 - 29x^2 - 114 where x= -4

tatiyna

Answer: -1410

Step-by-step explanation:

Let's start by subbing in -4 for x

$-4x^4 - 3x^3 - 29x^2 - 114\\-4(-4)^4-3(-4)^3-29(-4)^2-114$

Now we can solve

$-4(256)-3(-64)-29(16)-114\\-1024--192-464-114\\-832-464-114\\-1296-114\\-1410$

L = length of the rectangle
W = width of the rectangle

The area of the rectangle is:

A = L x W

If the cloth is cut along the diagonal, the area of one sail will be half the area of the rectangle:

A (one sail) = 1/2 (L x W) <span />
