It is given that z varies directly with x and inversely with the square of y so it follows:
It is also given that z=18 when x=6 and y=2 so it follows:
So the equation of variation becomes:
Therefore the value of z when x=7 and y=7 is given by:
Hence the value of z is 12/7 or 1.7143.
It's asking how far horizontally from the starting point which means that y, the height in meters is 0.
set 0 = -0.06x^2 + 10.1x + 5 and solve for x using the quadratic formula
-b +-
/ 2a
-10.1 +-
/ 2(-0.06)
you get that x = 168.83 m and -0.49 meters. Since the horizontal distance cant be negative, 168.83m is your answer
