B. I hope this help please let me know if it's correct.
8 - 45k - 40 = 3k - 1
-32 - 45k = 3k - 1
+ 1 +45k +45k + 1
_________________
-31 = 48k
-0.689 = k
We have that
H(t)=-4.9t²<span>+50t + 2
we know that
</span><span>The initial height of the rocket, in meters is for t=0 sec
fot t=0
H(t)=</span>-4.9*0²+50*0 + 2------> H(t)=2 m
the answer is
The initial height of the rocket is 2 m
76% of 150 would be 114 I think I’m not to sure tho
