y-intercept: 250
y= 150x+250
Step-by-step explanation:
Answer:
seconds
Step-by-step explanation:
h(t) = -16t² + 32t +8
0 = -16t² + 32t +8
0 =-0.125(-16t² + 32t+8)
0=2t²-3t-1
0=2t²-2t-t-1
Group
0=(2t²-2t)(-t-1)
0=2t(t-1)-1(t+1)
0=(2t-1)(t-1)(t+1)
0=2t-1 0=t-1 0=t+1
1/2(1)=(2t)1/2 0+1=t-1+1 0-1=t+1-1
0.5=t 1=t -1=t
t=0.5 t=1 t=-1
