The maximum height the ball reaches is 65.92 m.
The time taken for the ball to reach the maximum height is 3.06 seconds.
The time taken for the ball to hit the ground is 6.12 seconds.
<h3>maximum height the ball reaches</h3>
The maximum height the ball reaches is calculated as follows;
s(t) = -4.9t² + 30t + 20
at maximum height, final velocity = 0
v = 0
ds/dt = -9.8t + 30 = 0
9.8t = 30
t = 30/9.8
t = 3.06 seconds
s(3.06) = -4.9(3.06)² + 30(3.06) + 20
s(3.06) = 65.92 m
Thus, the time taken for the ball to reach the maximum height is 3.06 seconds.
<h3>Time of flight of the ball</h3>
The time taken for the ball to hit is the total time of flight = 2 x 3.06 seconds = 6.12 seconds.
Thus, the maximum height the ball reaches is 65.92 m.
The time taken for the ball to reach the maximum height is 3.06 seconds.
The time taken for the ball to hit the ground is 6.12 seconds.

Step-by-step explanation:
Given c = longest of triange = 15m
Given b = short side of triangle = 9m
By pythagoras' Theorem,
Sum of 2 and 8 is (2+8)
Then multiply by 5 will give us answer a. (2+8)x5

There are two intersection points (-1, 1) and (-2, 3), and the x coordinates are -1 and -2.
<h3>What is an exponential function?</h3>
It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent y = a^x
where a is a constant and a>1
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have two equations:
y = –2x – 1 and
From the graph, we can see:
There are two intersection points:
(-1, 1) and (-2, 3)
The x coordinates are -1 and -2
x = -1, y = 1
x = -2, y = 3
Thus, there are two intersection points (-1, 1) and (-2, 3), and the x coordinates are -1 and -2.
