Answer:
Therefore the width is 25 feet for getting maximum area.
The maximum area of the rectangle is 625 square feet.
Therefore the range is 0≤A≤625.
Step-by-step explanation:
Given function is
A = - x²+50x
We know that ,
If y = ax²+bx+c
For the maximum 
Here a = -1 , b= 50 and c=0
Therefore the width 
Therefore the width is 25 feet for getting maximum area.
The maximum area =[ -(25)²+50.25] square feet
= 625 square feet
The area can not be negative and maximum area is 625 square feet.
Therefore the range is 0≤A≤625.
The answer is a. number of boys < 89.
<span>1. </span><span>Well if the quotient is 45 ¼, the
divisor will depends on the dividend.
Since the dividend is not given, there it would be hard for us to tell what is
the divisor.
Because we only have the quotient, there are a lot of answers then if the
dividend is not given.
it can be that the divisor is 2 and the dividend is 90 ½ to be able to get 45 ¼
as an answer.
it’s hard to tell without identifying the dividend.</span>
