H=0
Therefore:
144t-16t²=0
t (144-16t)=0
We have two equations:
1)
t=0 (when the ball is released)
2)
144-16t=0
-16t=-144
t=-144 / -16=9 (this is the time )
Answer: the ball hit the ground in 9 s.
Answer:
B and D
Step-by-step explanation:
Because only those two equations on the graphs are straight. and are increasing or decreasing in a constant pace.
Answer:
2:3 , you divide by common denominator
i guess as a decimal it might be
.50 to .75 but dont take my word for it
Step-by-step explanation:
10 into 5 is 2
15 into 5 is 3
Answer:
8.06
Step-by-step explanation:
√(x2 - x1)² + (y2 - y1)²
√(6 - 2)² + (0 - 7)²
√(4)² + (-7)²
√(16) + (49)
√65
= 8.06
Answer:
I would say A. it makes the most sense.
