Answer:
![h(0)=400](https://tex.z-dn.net/?f=h%280%29%3D400)
The above function value for
shows that height of the ball before it was dropped i.e. at time = 0 seconds.
The height of the ball above the ground before it was dropped = 400 ft.
Step-by-step explanation:
Given:
The quadratic function that models the height of the baseball above the ground in feet ,
seconds after it was dropped is given as:
![h(t)=-16t^2+400](https://tex.z-dn.net/?f=h%28t%29%3D-16t%5E2%2B400)
To find
and interpret the meaning of the function value in contect of the problem.
Solution:
In order to find
, we will replace
in the given function as
is a function of time
.
Thus, we have:
![h(0)=-16(0)^2+400](https://tex.z-dn.net/?f=h%280%29%3D-16%280%29%5E2%2B400)
![h(0)=16(0)+400](https://tex.z-dn.net/?f=h%280%29%3D16%280%29%2B400)
![h(0)=0+400](https://tex.z-dn.net/?f=h%280%29%3D0%2B400)
(Answer)
The above function value for
shows that height of the ball before it was dropped i.e. at time = 0 seconds.
The height of the ball above the ground before it was dropped = 400 ft.
Using the table, we will see that the function is:
t(l) = 3*l
<h3>
How to write the function?</h3>
Here we only have a table to work with, so we need to use that.
In the table, we can see the pairs:
- t(1) = 3
- t(2) = 6
- t(3) = 9
- t(4) = 12
So, in each new level, we just add 3 more toothpicks. Even more, we can see that the number of toothpicks is 3 times the value of l (the level) for all the cases in the table. So this is a linear function.
From that we can conclude that the function will be:
t(l) = 3*l

Answer:
2 o'clock
Step-by-step explanation:
Their 'closing speed' is 60 - 50 = 10 km/hr
they have 20 km between them
at closing speed this will take 20 km / 10 km/hr = 2 hours for the cars to meet....this would be at 14:00 or 2 oclock
