SA =pi * r * s + pi * r^2
9^2 + 5^2 = s^2
81 + 25 = s^2
106 = s^2
s = 10.3
SA = pi * 5 * 10.3 + pi * 25
SA = 240.26

There are 1,000 residents of a town in Year 1. That number increases by 1% each year.

S_A_V [24]

Answer:

Part A) $y=1,000(1.01^{x})$

Part B) $1,105\ persons$

Step-by-step explanation:

Part A) What is the explicit rule for the number of residents

we know that

In this problem we have a exponential function of the form

$y=a(b^{x})$

where

a is the initial value

b is the base

r is the rate

(1+r)=b

Let

y ----> the number of residents

x is the time in years

we have

a=1,000 residents

r=1%=0.01

b=(1+0.01)=1.01

substitute

$y=1,000(1.01^{x})$

Part B) How many residents will there be in the town in Year 10?

For x=10 years

substitute in the equation

$y=1,000(1.01^{10})$

$y=1,105\ persons$
