Answer:
3 seconds
Step-by-step explanation:
When the ball hits the ground, the height will be 0. Therefore, you can substitute 0 in for the value of f(t), hence the equation will be:
0 = -16t^2 + 32t + 48
You can then factor out -16:
0 = t^2 - 2t - 3
Factor:
0 = (t-3)(t+1)
t = 3, -1
However -1 is an extraneous solution because time cannot be negative. Therefore, the answer is 3 seconds.
The first one is an octagon the second one is a petegon third is a trapezoid the fourth one is a parallelagram the fifth one is rectangle sixth is a decagon the lst one is a heptagon
Answer:
i think it is f(x)= 10m+0.10s
x= number text messages send
m= months
for example: if you send 200 messages and were in the plan for 3 month the function will go like this;
f(x)= 10(3)+0.10(200)
=30+20
= $50
Answer:
-- Acme
--- Bell
Step-by-step explanation:
Given
Acme:
Bell:
Required
Determine the cost function for both
The cost function can be determined using the following illustrations:
Daily Rate + Hourly Rate * Number of Hours
Represent the number of hours with x
So, we have:
For Acme:
For Bell:
