Answer:
yes x=4 is a solution
Step-by-step explanation:
45x = 180
divide each side by 45
45x/45 = 180/45
x = 4
x=4 is a solution

Step-by-step explanation:
Answer:
Graph B represents a function.
Step-by-step explanation:
Graph B is a quadratic function. y = x^2
I assume you are looking for the formula, and the velocity.
The formula:
v1^2-v0^2=2aS
where
v0=initial velocity (0 if object falls from rest), ft/s
v1=velocity reached after falling a distance S, ft/s
S=distance from initial position, positive downwards (for falling objects), ft
a=acceleration due to gravity, 32.2 ft/s^2 in imperial units
So substituting numbers, assuming initial velocity is zero (from rest), then
S=25 ft
v1^2-0^2=2*32.2*25
v1^2=1610
v1=sqrt(1610)
=40.1 ft/s
