Answer: Divide the first equation, −4x + 8y = 16, by 2
Step-by-step explanation:
Use these conversions:
1 foot = 12 in
1 mile = 5280 feet
67000 in * [1 ft /12 in] * [1 mile/5280 ft]
Then the answer is the option c.
0.001)) milli to grams is x 1000
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.
