Answer:
1 seconds after being thrown, the stone reaches its max height
Step-by-step explanation:
The parabolic (quadratic) equation is:

Lets expand this in the form
, so we have:

We can say the values of a,b, and c, now to be:
a = -5
b = 10
c = 40
The number of seconds at which the max would occur is given by the point, x, at:

We know a and b, let's find the seconds, x,

Hence,
1 seconds after being thrown, the stone reach its max height

Step-by-step explanation:
<u>Step 1: Define</u>
j(x) = x + 5
j(12) is x = 12
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: j(12) = 12 + 5
- Add: j(12) = 17
