Answer:
t = 3 seconds
Step-by-step explanation:
Here h(t) = -16t^2 + 144.
When the quarter hits the ground, its height will be 0 feet. Letting h(t) = 0 results in -16t^2 + 144 = 0, or 16t^2 = 144, or
144
t^2 = ------------ = 36/4 = 9 seconds^2
16
Therefore, the time, t, required for the quarter to hit the ground is t = √9, or t = 3 seconds
Y=mx+b
m=slope
b=yintercept
given
slope=2/3=m
yintercept=9=b
y=2/3x+9
The answer is $3,960
you multiply 220,000 by 0.03 to get the amount the broker takes which is $6,600
you then multiply 6,600 by 0.60 to get the amount the agent receives, being $3,960
