Answer:
B 5 seconds
Step-by-step explanation:
h = 240 + 32t – 16t^2
When is this equation 0
0 = 240 + 32t – 16t^2
Factor out 16
0 = -16(-15-2t+t^2)
= -16(t^2-2t-15)
What 2 numbers multiply to -15 and add to -2
-5*3 = -15
-5+3 =-2
0 = -16(t-5) (t+3)
Using the zero product property
t-5=0 t+3=0
t=5 t=-3
Since time cannot be negative
t=5 seconds
12,000 Students Applied...
To find the answer, consider that for every 1000 students that apply, 150 students are accepted.
Divide 1800 by 150 and you get 12....which can be translated to 12,000 students
The Perimeter of Triangle ABC would be 60.
You can solve this by setting up proportions.
