Which of the following represents this function written in standard form? y=2(x-1)(x-6)
A. v=2x^2 - 14x+12
B. y= 2x^2 - 12+6
C. y= 2x^2 – 7x+12
D. y=2x^2– 12x+12

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
