Answer:
5 seconds
Step-by-step explanation:
The ground is 25 eet, so 25=-16t^2+400
-16t^2=-400, 16t^2=400
t^2=25, dividing both sides by 16
t=5 seconds.

Answer:
The scale factor is 4.5
Step-by-step explanation:
Scale factor from ∆RST to ∆XYZ = side length of ∆XYZ / corresponding side length of ∆RST
Thus:
XY corresponds to RS
XY = 45
RS = 10
Therefore:
Scale factor = 45/10 = 4.5
Scale factor from ∆RST to ∆XYZ = 4.5
