How many objects are required to keep the computer busy for exactly 7 seconds?

48 objects

Step-by-step explanation:

The number of objects that the computer can sort (x) in t seconds is modeled by the function.

To determine the number of objects required to keep the computer busy for 7 seconds, we must put into the equation and solve for x.

This implies that;

or

We use the quadratic formula with a=3,b=1,c=-7000

We substitute the values to obtain;

We discard value and obtain the number of objects to be 48 to nearest whole object.
