There are no numbers for this, thus you will have to use the quadratic formula.
The answer is A. Good luck man!! :)
Answer:
Step-by-step explanation:
From the law of variation,
y <> 1/x, where <> is the constant of proportionality. Therefore
y = k/x where k is a constant
3 = k/5 and k = 15
To find x when y = 2.5(5/2)
Go back to the second equation
y = k/x
5/2 = 15/x
When you cross multiply
5x = 30.
Divide through by 5,
x = 6.
The area is 18 units squared, I believe.
(4 sec) * (-10 ft/sec) = -40 ft.
