Answer:
60cm
Step-by-step explanation:
perimeter of a square=4L
192cm=4L
L=48cm
Dilated by ratio 0.25
1 : 0.25 = 48 : 12
New length = 48+12 = 60cm.
The information is really hard to follow, you should ask the question with a screenshot of the data table.
It hits the ground at h=0
0=-16t^2-16t+96
undistribute -16
0=-16(t^2+t-6)
factor
0=-16(t-2)(t+3)
set to zero
0=t-2
2=t
t+3=0
t=-3, nope, we can't have negative time
at t=2, or 2 seconds
Step-by-step explanation:
let us consider the elevation of the sun is x
then
x=6×6
x=36
