Vertex Angle = 180 -54 -54Vertex Angle =72 degrees
Answer:
Step-by-step explanation:
I didn’t see any choices but an inverse function switches the x and y values.
For every (x,y) of f(x) the inverse function will have (y,x) of f^-1(x)
Here's the first equation:
w = l - 7
Knowing this:
l*w = 98
Input w:
l*(l - 7) = 98
l^2 - 7l - 98 = 0
Factor:
(l-14)(l+7) = 0
Length can't be a negative number, -7 is rejected
The length is 14, the width is 7
Answer:
$16.59
Step-by-step explanation:
$15.88 * 4.5/100
=0.7146 + $15.88
= $16.59
