Answer:
Step-by-step explanation:
There's the two widths, x.
There's the four lengths, y.
4y+2x=600
Also, A=xy.
x=300-2y
A=y*(300-2y)
dA/dy=0= y*(-2)+(300-2y)
-2y-2y+300=0
y=300/4=150/2=75
x=300-2y=300-150=150
Then the long side is 150ft, the short side is 75ft.
Check to make sure that the sum of the lengths is 600: 300+300=600
And the maximum area is 150*75 ft2

Answer:
The rate of change for the given function between x=3 and x=7 is 19
Step-by-step explanation:
Given function is:
Can also be written as:
The rate of change of a function is given by the formula:
In the given question,
We have to find rate of change between 3 and 7
Here
b = 7 and a = 3
WE have to find f(7) and f(3) first
So,
Putting the values in the formula
Hence,
The rate of change for the given function between x=3 and x=7 is 19
When looking for the least common multiple, you are looking for the smallest multiple that they both divide into evenly. the least common multiple of 4 and 7 is 28.
