Answer:

48 objects

Explanation:

we have


t=0.003x^(2)+0.001x

where

t is the number of seconds

x is the number of objects

For t=7 sec

substitute in the equation and solve for x


7=0.003x^(2)+0.001x

Solve the quadratic equation by graphing

The solution is x=48 objects

see the attached figure
