Answer:

Step-by-step explanation:
We know that the equation that models the height of the ball as a function of time is
.
Where the initial speed is 80 feet.
When the ball lands on the ground, its height will be
.
So to know how long it will take the ball to reach the ground, equal h (t) to zero and solve for t.

To solve this quadratic equation we use the quadratic formula.
For an equation of the form:

The quadratic formula is:

In this case

Then


We take the positive solution

Answer:
To understand roads and subways at new places.
To calculate distance between two places.
To know whether there are two or more paths to the same place and which is the shortest.
We can get information about mountains, rivers, valleys or any other thing, which may come on the way, and we can prepare for that.
There is a bias in this sampling method.
The interviewer only interviews people exiting a local restaurant, which means it's more likely for the people to go out to eat regularly.
