The function f(x)=(x+8)3 is​ one-to-one. Find an equation for f−1(x)​, the inverse function.

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh

all of the measures need to be converted to the same measure; such as inches. if you do that it is easy to determine which is the longest, 2500 mm which is approximately 97.5 inches.

answer is  

a.

5.2 inches

hope you get this right.

x=-2

step-by-step explanation:

28-32x=92

-32x=92-28

-32x=64

x=64/-32

x=-2
