The graph shows two exponential functions. Choose the correct statement concerning their bases

A) C = -b

B) c = 1 - b

C) c = b - 1

D) c = 1/b

D

Step-by-step explanation:

The two graphs are reflections of each other in the y-axis

If one is f(x), other is f(-x)

c^x = b^(-x)

c = b^-1

c = 1/b

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
