5/4. Is the answer what ever is next to the variable x
1 yd = 3 ft
39 ft/m = 13 yd/m
1 min = 60 sec
13 yd/60 sec = .21667 yd/sec
To figure out the solution in a problem related to calculate maximum or minimum of something, you've to derive the involved equation, and make it equal to 0, solving the x.
So:
y = -0'296x² + 2'7x
y' = -0'592x + 2'7
0 = <span>-0'592x + 2'7
</span><span>-0'592x = 2'7
</span>x = 4'56
And if we substitute 4'56 on the first equation:
y = -0'296·<span>4'56² + 2'7·4'56
y = 6'16
So the length of the jump is 4'56cm, and the height 6'16cm.</span>
