Answer:
Step-by-step explanation:
let x,y be the sides of court.
2(x+y)=90
x+y=90/2=45
y=45-x
xy=500
x(45-x)=500
45x-x²=500
x²-45x+500=0
x²-25x-20x+500=0
x(x-25)-20(x-25)=0
(x-25)(x-20)=0
x=25,20
when x=25
y=45-x=45-25=20
when x=20
y=45-20=25
sides are 25 ft,20 ft.
X/100 = 52/260
100•52=5200
5200/260 = 20
20%
I don't know if this helps but my calculator said 4.2189246e+21
Answer:
A)85
Step-by-step explanation:
Calculation for the resulting tracking signal
Using this formula
Tracking signal= Last forecast error statistics (RSFE) /Low MAD (Mean Absolute Deviation)
Let plug in the formula
Tracking signal=34/0.4
Tracking signal=85
Therefore the resulting tracking signal will be 85
