If a computer can do one calculation in 0.15 seconds, then the function T(n) = 0.15n gives the time required for the computer to do n
calculations. Describe what represents the independent and dependent variables in this
problem? Is this continuous or discrete? How do you know?

54

Step-by-step explanation:

Because I like this number

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
