Question

A computer can sort x objects in t seconds, as modeled by the function below t=0.003x^2 + 0.001x how long in seconds will it take the computer to sort 12 objects

Answer 1

`t=0.444\ seconds`

Explanation:

Let

x -----> the number of objects

t ----> the time in seconds

we have

`t=0.003x^(2)+0.001x`

For x=12 objects

substitute in the formula and solve for t

`t=0.003(12)^(2)+0.001(12)`

`t=0.444\ seconds`
