Gabe drops a hammer from an apartment that is 30 meters above the ground. the height of the hammer in meters, h, after t seconds is modeled by the function below.
h(t)=-t^2-2t+30
find the approximate number of seconds it will take for the hammer to hit the ground. round your answer to the nearest whole number.
a. 0
b. 5
c. 10
d. 30
Answer from: kimezzell18
Simplifying
h(t) = -1t2 + -2t + 30
Multiply h * t
ht = -1t2 + -2t + 30
Reorder the terms:
ht = 30 + -2t + -1t2
Solving
ht = 30 + -2t + -1t2
Solving for variable 'h'.
Move all terms containing h to the left, all other terms to the right.
Divide each side by 't'.
h = 30t-1 + -2 + -1t
Simplifying
h = 30t-1 + -2 + -1t
Reorder the terms:
h = -2 + 30t-1 + -1t
