The function V(t) = 2.99(1.12) represents the value V(t), in dollars, of a commemorative box of Wheaties t years after its purchase in 2000. Determine the annual growth rate in the value of the Wheaties box. How much is the box worth currently in the year 2021)? Round to the nearest cent (2 decimal places)

The annual growth rate in the value of the Wheaties box = 12%

The box worth $32.30 currently in the year 2021.

Step-by-step explanation:

Exponential growth function : , where a =  initial value, r= rate of growth , x= time  (i)

Given: , where  V(t) = value of a commemorative box of Wheaties t years after its purchase in 2000.

It can written as

Comparing above function with (i), we get r=0.12

The annual growth rate in the value of the Wheaties box = 12%

Now , For 2021 ,  t=2021-2000=21

Hence, the box worth $32.30 currently in the year 2021.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

17 1/3
