I just took that quiz on k12. The answer is no solution. Hope I helped!
Answer:
5/2
Step-by-step explanation:
g(-3) falls under x<=-1 so substitute -3 on x
-1/2(-3)+1
3/2+1
5/2
The square root of 234 is 15.2970585408
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
