Answer:
Time taken for the ball to hit the ground back = 3.08 s
Step-by-step explanation:
h(t)= -16t² + 48t + 4
when will rhe object come back to hit rhe ground?
When the ball is at the level.of the ground, h(t) = 0.
0 = -16t² + 48t + 4
-16t² + 48t + 4 = 0
Solving the quadratic equation
t = 3.08 s or t = -0.08 s
Since the time cannot be negative,
Time taken for the ball to hit the ground back = 3.08 s
Hope this Helps!!!

Step-by-step explanation:
The simplified form of the expression 1/6 (30x + 24) – 1/7 (63 – 7x) will be 6x – 5.
The complete question is given below.
<h3>What is simplification?</h3>
Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
The expression is given below.
⇒ 1/6 (30x + 24) – 1/7 (63 – 7x)
By simplifying we have
⇒ 1/6 × 30x + 1/6 × 24 – 1/7 × 63 + 1/7 × 7x
⇒ 5x + 4 – 9 + x
⇒ 6x – 5
Then the simplification process is done.
