The length of a rectangle is 88 inches longer than the width. If the perimeter of the rectangle is 7272 inches, find the measur

tresset_1 [31]

The perimeter (IP) of a rectangle is

P = 2(length + width)

let width = w then length = w + 88

P = 2(w+w+88) = 2(2w+88) = 4w+176

Thus P = 4w+176 = 7272

hence 4w = 7272 - 176 = 7096

so w = 7096/4 = 1774

width = 1774 inches and length = w+88 = 1774+88 = 1862 inches

Write the inverse of h(x) = e 2x h -1(x) = log e2 x 2log ex ½log ex

svp [43]

Answer:

Step-by-step explanation:

So we have the function:

$h(x)=e^{2x}$

To find the inverse, switch h(x) and x, change h(x) to h⁻¹(x), and solve for it. Thus: "

$x=e^{2h^{-1}(x)}$

So, take the natural log (log to base e) of both sides:

$\ln(x)=\ln(e^{2h^{-1}(x)})$

The right side will cancel:

$\ln(x)=2h^{-1}(x)$

Divide both sides by 2:

$h^{-1}(x)=\frac{1}{2}\ln(x)$

And we're done!

Our answer is C

Note:

$\ln(x)=\log_ex$

-4/9 * -5/8 I really want to know the answer home work is due and I need a explanation

lilavasa [31]

-4/9 times -5/8 you can cross cancel the 4 and 8 so it makes the problem -1/9 times -5/2 which equals -5/18
