Answer:
4.5%
Step-by-step explanation:
If y varies directly as the square of x, that means that y=k*x^2. Plugging y=100 and x=5 into it, we get 100=k*5^2=k*25. Dividing by both sides, we get k=100/25=4. Going back to the original equation, we now know that y=4*x^2. Plugging 9=x in, we get 4*9^2=4*81=324=y
Answer:
Step-by-step explanation:
y=-f(x) means a reflection over the x axis so that means the coordinates will be (x,-y). The coordates will be opposite her and the max will be (6,0)

Answer:
45 people.
Step-by-step explanation:
