A bacteria colony grow at a rate of 11% per year. If the initial sample has a mass of 500 grams, which of the following functions models the size of the colony in grams t years later?

A) f(t)=500(.89)^t
B) f(t)=500(1.11)^t
C) f(t)=11(500)^t
D) f(t)=11(1.5)^t

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,

-232
