If a $1,200 investment earns $210 over 5 years, what is the annual interest rate?

The annual interest rate is 41.7%.

Step-by-step explanation:

Given : If a $1,200 investment earns $210 over 5 years.

To find : What is the annual interest rate?

Solution :

Using compound interest formula,

Where, A=$1200 is the amount

P=$210 is the principal

t=5 years is the time

r is the interest rate.

Substitute the value,

Taking 5th root both side,

Interest rate in percentage,

The annual interest rate is 41.7%.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

35 is an outlier
