Answer:
A) 1 : 4
B) 1 : 2
C) Base of M = 10 units
Step-by-step explanation:
A)
The ratio of the area of triangle M to triangle N
B)
The ratio of the side lengths of triangle M to triangle N
C) Let the base of triangle M be b units.

Height in feet is represented by 
The height of the ball is 0 feet when it hits the ground.
So we replace height f(x) by 0 and solve for x to find the time taken to reach the ground

( divide by -16 on both sides)

Now factor it
(x-6)(x+1) =0
x-6 =0 and x+1=0
x=6 and x=-1
Time cannot be negative so we ignore -1
x = 6 seconds
It will take 6 seconds for the ball to reach the ground.
