Question

A computer can sort x objects in t seconds, as modeled by the function below:

t=0.005x^2+0.002x

How long, in seconds, will it take the computer to sort 10 objects?

Round your answer to the nearest hundredth of a second. ...?

Answer 1

The answer is 0.52 s

The function is t = 0.005x² + 0.002x

x = 10

Substitute x into the function:
t = 0.005 * 10² + 0.002 * 10
t = 0.005 * 100 + 0.02
t = 0.5 + 0.02
t = 0.52 s
