Which of the following is an exponential model that shows an initial investment of $200 dwindling by 3% annually.
A. a(t) = 200(1+0.03)
B. a(t)= 200(1 – 0.03)
C. a(/) = 200(1-0.3)
D. alt)= 200(1-3)

Option A. a(t) = 200(1+0.03)

Step-by-step explanation:

Given data

principal P= $200

rate r= 3%

time t= 1 year

Required

The final amount A

We know that the expression for the simple interest is given as

A=P(1+rt)

so the equivalent expression is

A. a(t) = 200(1+0.03)

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
