Answer:
18
Step-by-step explanation:
plug 4 for z
3(4)+6=18
First find the time that the ball is level with the top of the building on its descent. You can do this by solving 280 = -16^2 + 48t + 280 for t. This gives t = 3 seconds .
Then when the ball reaches the ground the time t is obtained by solving 0 = -16t^2 + 48t + 280 This gives t = 5.94 seconds.
Answer in interval notation is (3, 5.94].
Answer:
C. 93 cars
Step-by-step explanation:

Answer:
40%
Step-by-step explanation:
10/4 = .4
.4 = 40%
So this is taking this equation and plugging it into the quadratic formula -b+- (sqrt (b^2)-(4)ac)/2a so your A value is 1 B value is 3 and C value is -5 so it’s B&E
