Answer:
Brewed Coffee
4
Step-by-step explanation:
H=-16t^2+49
find where h=0
0=49-16t^2
0=7^2-(4t)^2
difference of 2 perfect square
0=(7-4t)(7+4t)
set to zero
7-4t=0
7=4t
7/4=t
7+4t=0
4t=-7
t=-7/4
faslse, this is before the person jumps
answer is 7/4 seconds
First, simplify the parenthesis. You’ll get:
1/4(4z)+7=-z+1
Then multiply 1/4 by 4z. You’ll get:
z+7=-z+1
Love like terms to the same side. I wanted to have the variable positive on time, so I moved variables to the left and constants to the right. You’ll get:
2z=-6
Divide both sides by 2. You’ll get :
z=-3
