<PRE><B>Question 956644</B>
A computer can sort x objects in t seconds, as modeled by the function below:
 t= 0.003x^2 + 0.001x
 How many objects are required to keep the computer busy for exactly 7 seconds?
 Round to the nearest whole object. 
====
0.003x^2 + 0.001x = 7
Multiply thru by 1000 to get:
3x^2 + x - 7000 = 0
x = 48.13821
-------------
Ans:: 49
