A computer can sort x objects in t seconds, as modeled by the function below:
t=0.007x2 + 0.003.x
How long, in seconds, will it take the computer to sort 15 objects?

it will take 0.056025 seconds to complete

Step-by-step explanation:

Here, we want to know the amount of time it will take. the computer to sort 15 items.

What to do here is simply substitute the value of 15 for x

Thus, we have

t = 0.007(15)^2 + 0.003(15)

t = 0.011025 + 0.045

t = 0.056025
