A rock was thrown from the top of a cliff that its distance above sea level was given by s(t)=at^2 + bt +c , where t is time in seconds after the rock was released. After 1 second the rock was 63 metres above sea level, after 2 seconds 72 m and after 7 seconds 27m. Find an expression for s(t).

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

i dont know what you want me to answer for this but im guessing 2: 11?
