Answer:
X = 45
Step-by-step explanation:
90 + X + A = 180 (angles of a triangle sum to 180)
90 + X + 45 = 180
X = 45
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
Answer: B, the are parallel but not equal. They are parallel line because they move in the same direction and they are not equal because they have different magnitude.
