Step-by-step explanation:
Answer:
n=22 or 252=11(22)+10
Step-by-step explanation: 252=11n+10. Start by attempting to isolate the varyable by subracting 10 from both sides--> 242=11n, divide by 11--> 22=n
PROOF 252=11*22+10=242+10=252
H(t) = -16t^2 + 128t
h(5) = -16(5)^2 + 128(5)
h(5)= -16(25) + 640
h(5) = - 400 + 640
h (5) = 240
