The ball was initially thrown from a height of 5.5 feet and 5.5 is y intercept that it throm from 5.5 feet.
Let x = the other rational number.
x(66/7) = (48/5)
Solve for x to find your answer.
B and c would be answered
Answer:
t = 4 seconds
Step-by-step explanation:
The height of a soccer ball as a function of time is given by :
We need to find the time when the ball hit the ground i.e. h = 0
Put h = 0 in above equation. So,
It is a quadratic equation such that,
t = -1 s and t = 4 s
Neglecting -1 s, the ball will hit the ground after 4 seconds.
