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
Answer:
this is the most that you can factor it... is there anything more to the q?
Answer:x 31.5 mm
Step-by-step explanation:I hope this helps

Answer: Circumference is approximately 75.36 feet</h3>
=======================================================
Work Shown:
d = diameter = 24 ft
pi = 3.14 approx
C = circumference of circle
C = pi*d
C = 3.14*24
C = 75.36 feet
Slope = (y2 - y1)/(x2 - x1) = (10 - 70)/(5 - (-15)) = -60/(5 + 15) = -60/20 = -3
