H(t) = -16t² + 144
When will the object hit the ground? This means that the height will equal to 0.
h(t) = 0
0 = -16t² + 144
16t² = 144
t² = 144/16
t² = 9
√t² = √9
t = 3
The object will hit the ground after 3 seconds.
Answer:
t = X - Xt - 1
Step-by-step explanation:
X=1+t/1-t
Multiply both both sides by 1 - t
X(1 - t) = 1 + t
X - Xt = 1 + t
t = X - Xt - 1
361 times 1 is 361
hoped i helped!!
5x+y that's if there isn't more to this question or to the equation
