Answer:
7.7 seconds
Step-by-step explanation:
The solution is given by the quadratic formula.
For ax² +bx +c = 0, the roots are ...
x = (-b±√(b²-4ac))/(2a)
We want the positive root, so ...
x = (-113 -√(113² -4(-16)(74)))/(2(-16)) = (113 +√17505)/32 ≈ 7.6658
The rocket will hit the ground about 7.7 seconds after it is launched.
The answer is 256 ,

Total Population= 11800÷26
Step-by-step explanation:
- Number of animals captured,tagged and released= 118
- In capture/recapture program 26% have tags
i.e, 26% of total animals= 118
Let total number of animals = P
(26÷100)× P =118
26 P =118×100
P=11800÷26
