1. 20.1%
You find this by subtracting the measured and the actual and then divide that by the actual. Then, multiply that by 100 to get the percent.
Your slope is
negative 11 over 3 !!!
Or approximately 3.67 (rounded)

By solving a quadratic equation, we will see that the ball hits the ground after 2.6 seconds.
<h3>How long does it take for the ball to hit the ground?</h3>
Here we need to solve the equation:
h(t) = 0 = -16t² + 40t + 4
This represents that the ball hits the ground.
So we just need to solve that quadratic equation, using the general formula we get:
We only care for the positive solution, which is:
t = (-40 - 43.1)/-32 = 2.6s
So the ball hits the ground after 2.6 seconds.

Answer:
<h3>
A Geometric sequence with common ratio 3</h3>
Step-by-step explanation:
A sequence of number is called Geometric sequence if the first number is being multiplied with a constant to get the rest of the numbers
ratio between 2 adjacent numbers in a sequence will be a constant and is called common ratio.
in the given sequence the ratio between any pair of adjacent numbers is 3.
∵ this is a geometric sequence with common ratio 3
