Answer:
B. (-1,7)
C. (0,5)
D. (2,3)
Step-by-step explanation:
We solve this question looking at the graphic.
A. (-7, 1)
When 
, and thus (7,-1) is not solution of the equation.
B. (-1,7)
When 
, and thus (-1,7) is a solution of the equation.
C. (0,5)
When 
, and thus (0,5) is a solution of the equation.
D. (2,3)
When 
, and thus (2,3) is a solution of the equation.
E. (3, 2)
When 
, and thus (3,2) is not part of the solution
F. (5,0)
When 
, and thus (5,0) is not part of the solution
For this case we have the following equation:
h (t) = - 12t2 + 36t
When the object hits the ground we have:
- 12t2 + 36t = 0
We look for the roots of the polynomial:
t1 = 0
t2 = 3
Therefore, the time it takes the object to hit the ground is:
t = 3 s
Answer:
the time when the object hits the ground is:
t = 3 s
