Answer 1

Answer:

20%

Step-by-step explanation:

To find growth rate in compound growths, we can look at a general formula. Shown below:

$f(x)=a(b)^x$

Where a is the initial amount

b is the growth factor

x is time

In our formula given, we see that b = 1.2

What growth does this represent??

Well, the amount that is OVER 1, is the growth. Simple!

So, we take the value of b and then subtract 1 from it. Then we multiply that answer with 100 to get a PERCENTAGE GROWTH RATE. Let's do this on b:

b = 1.2

b - 1 = 1.2 - 1 = 0.2

0.2 * 100 = 20

Which is 20%!

So the growth rate is 20%

Answer 2

Answer:

B

Step-by-step explanation:

An exponential function may be given by:

f(x) = A(1+r)^x

A is the initial amount and r is a decimal representing the growth rate.

We can see that 1+r = 1.2, and we solve for r:

1 + r = 1.2

r = 0.2

The growth rate is 0.2, or 20%
