When the ball will hit the ground, the height will be zero. So we need to replace

with 0 in our equation, and solve for

:


To solve this equation we are going to use the quadratic formula:

.
From our height equation, we can infer that

,

, and

. So lets replace those values in our quadratic formula to find



or


or

Since time cannot be negative,

is the solution of our equation.
We can conclude that the ball will hit the ground after
2.71 seconds.
Answer:
For which list does the total number have meaning? (What to see at the zoo)
For the list of facts it (does not) make sense to add the cost of a past, the area and the employees because these quantities (cannot) be expressed using the same unit. The number of 168 (does not) have meaning for the list
Step-by-step explanation:
Area is usually described in square feet while a population has no unit and a price is described in dollars therefore the list of facts has no meaning ( i got this question correct)
