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.
Answer:
Step-by-step explanation:
.95
I don't know what the easiest way to do this is. I just divide 19 by 2 and shift the decimal around. That doesn't sound very helpful.
The answer should be nearly one. It should be less than one, but not by much.
So divide 19 by 2 and you get 9.5 but you know that the answer is less than one, so shift it one more place to the left.
Answer:
![22.3](https://tex.z-dn.net/?f=22.3)
Step-by-step explanation:
Rounding each number to the nearest tenth means that you're rounding a number up by one decimal place.
19.75 will become 19.8
2.49 will become 2.5
![19.8 + 2.5 = 22.3](https://tex.z-dn.net/?f=19.8%20%2B%202.5%20%3D%2022.3)
Good luck!
