The y-intercept is (0,-1)
X= y/21 -2/21
Hope it helps :)
I think I am more towards c but I am stuck between c and d
Using one of the equations for costant acceleration
s = ut + 0.5gt^2 + 80
s = 64t - 16t^2 + 80
s = -16t^2 + 64t + 80
= -16[ t^2 - 4t) + 80
= -16 ( t - 2)^2 + 64 + 80
= -16(t - 2)^2 + 144
Time to maximum height = 2 seconds
Maximum height = 144 ft
Displacement when it hits the ground = -80 so
-80 = -16t^2 + 64t + 80
solve for t
t = 5.74 seconds
Answer:
The distributive property
Step-by-step explanation:
When you have a number on the outside of a set of parenthesis, you can remove the parenthesis by multiplying the term on the outside by each of the terms on the inside. This is known as the distributive property.
