Question 417878: In this equation, h=-16t^2+20t+300, can you help me make tables of values for the height equation, with increments of 0.5 seconds. And can you show me how you got that
Answer by ankor@dixie-net.com(22740)   (Show Source):
You can put this solution on YOUR website! h = -16t^2 + 20t + 300,
:
Make a table for every .5 sec
:
Start with t = 0, substitute 0 for t in the given equation, find h
h = -16(0^2) + 20(0) + 300
h = 0 + 0 + 300
h = 300
:
t = .5
h = -16(.5^2) + 20(.5) + 300
h = -16(.25) + 20(.5) + 300
h = -4 + 10 + 300
h = 306
:
t = 1
h = -16(1^2) + 20(1) + 300
h = -16 + 20 + 300
h = 304
:
t = 1.5
h = -16(1.5^2) + 20(1.5) + 300
h = -16(2.25) + 30 + 300
h = -36 + 30 + 300
h = 294
The table would be like this
t | h
-------
0 | 300
.5 | 306
1.0| 304
1.5| 296
2.0|
2.5|
3.0| 216
3.5|
4.0|
4.5|
5.0| 0, strikes the ground in 5 sec (h=0)
:
You should be able to fill in the missing values for h, in the same manner.
:
If you plot these points as x,y coordinates on a graph, it should look like this
