A. 176 because if there are 252 total and 76 on the balcony your answer is 252-76.
Answer: after 3 seconds
when the ball hit the ground => - 5t² + 14t + 3 = 0
⇔ (5t + 1)(t - 3) = 0
⇔ t = 3 or t = -1/5
but t is a positive integer => t = 3
so the ball will hit the ground after 3 seconds
Step-by-step explanation:
X=1. In the formula=yx =k where k is 120 so you will equate. This implies that yx=120 eqn1 and y=x+7 eqn 2
The y-intercept is (0,4) you can use photomath for problems like this an others
