The equation that we can create from this situation is:
i = (190 – 5 x) * (29 + x)
where i is the income and x is the increase in daily rate
Expanding the equation:
i = 5510 + 190x – 145x - 5x^2
i = -5x^2 + 45x + 5510
Taking the 1st derivative:
di/dx = -10x +45
Set to zero to get the maxima:
-10x + 45 = 0
x = 4.5
So the cars should be rented at:
29 + x = 33.5 dollars per day
The maximum income is:
i = (190 – 5*4.5) * (33.5)
i = 5,611.25 dollars

Answer:
7
Step-by-step explanation:
75% of 28 is 21.
21 pairs are tennis
So,
28-21=7.
7 pairs left!
Here we are give the value for π and Diameter of the circle fence
π=3.14
Diameter = 16
Radius = Diameter/2
2πr = 2(3.14)(8)
Circumference = 50.27
Now to fine the square fence length so we do 16*4 = 64
64-50.27 = 13.73 in
Therefore, the square fence is 13.73 inches longer than the circle fence
