Answer:
y = 4
Step-by-step explanation:
-12= -3y
Divide both sides of the equation by
the same term

Simplify
Divide the numbers
Cancel terms that are in both the
merator and denominator
Move the variable to the left
y = 4
Y=7,500(1+0.0275)^x
y=7,500(1.0275)^10
y=9,837.38
So you want height to be 0 so you plug zero into the height and solve from there. You subtract 192 from both sides to get -192=-16tsquared. Then you would divide by -16 and end up with 12 = t^2. Then you find the square root of 12 and get t = 3.464 seconds.
