Question 955017: A horse runs along the road. Its distance from the lamp post P on the side of the road is measured at different times, t, and has the form d(t)=at^2+bt+5
The distances are recorded in the table below:
Time(in seconds) 1 2 3 4 5 6
Distance(meters) 10 17 g 37 h 65
So 1 corresponds with 10 and 2 with 17 and so forth.
Determine the values of a and b, for d(t)=at^2+bt+5
(1) a=1 and b=4
(2) a=19/3 (6.33333..) and b=-4/3 (-1.33333..)
(3) a=-9 and b=24
(4) a=6 and b=-1
(5) or none of the above

--------------
3 points are (0,0), (3.5,4) and (7,0)
y = ax^2 + bx + c
At x = 0, y = 0 --> c = 0
----
At x = 7, y = 0
49a + 7b = 0
7a + b = 0
b = -7a
---
At x = 3.5, y = 4
12.25a + 3.5b = 4
Sub for b
12.25a - 24.5a = 4
-12.25a = 4
a = -16/49
---
b = 16/7
-------------
And then they got
y=16x^2/49+16x/7
What I am wondering is how you got there, because I have looked very hard a it and can not make sense of it, would someone please explain the process a bit more clearly?
