For
y=ax²+bx+c
the x value of the axis of symmetry is -b/(2a)
so test them
A., -b/(2a)=-(-8)/(2*-2)=8/-4=-2, yep
B. -b/(2a)=-2/(2*1/2)=-2/1=-2, yep
C. -b/(2a)=-(-16)/(2*4)=16/8=2, nope, need -2
D. -b/(2a)=-12/(2*3)=-12/6=-2, yep
answer is C
Subtract the distance of the Earth from the sun from the distance of Saturn from the sun to find the distance from Earth to Saturn:
1,424,000,000 - 149,600,000 = 1,274,400,000 km ( Saturn from Earth)
Divide the distance by the speed to find the time:
1,274,400,000 km / 28,000 km per hour = 45,514.2857 hours.
Round to 45,514 hours.
