Answer:
y = -7/2x + 17/2
Step-by-step explanation:
Slope = (-9 - - 2)/(5 - 3)
= -7/2
y-intercept: -2 - (-7/2)(3)
= -2 + 21/2 (-2*2+21)/2
= 17/2

The number of gallons of water in the tank at t=10 is
... W(10) = 160,000 -10(8000 -10) = 80100
The number of gallons of water in the tank at t=10.5 is
... W(10.5) = 160,000 -10.5(8000 -10.5) = 76110.25
The rate of change over the interval is
... (W(10.5) - W(10))/(10.5 - 10) = (76110.25 - 80100)/(0.5) = -7979.5
The average rate of change in the number of gallons of water in the tank over the interval is -7979.5 gal/min.
The sign is negative, so the amount of water is decreasing.
Answer:
The rate of return is 14%
Step-by-step explanation:
The rate of return can be determined by,
RR =
x 100%
where:
RR is the rate of return
is the final amount = $690 - $6 = $684
is the initial amount = $15 x 40 = $ 600
So that,
RR =
x 100%
= 0.14 x 100%
= 14%
Therefore, the rate of return is 14%.
