You invested $3,500 at 8 percent simple interest. How much more could you have earned over a 7-year period if the interest had compounded annually?

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

true? is that what you're asking or do you mean something else?

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

step-by-step explanation:

mean or average is 40.6
