Ok guys : use the information provided to write the vertex form equation of each parabola y=-12x^2+192x-769 explain this is a grade
2)solve each equation by completing the square : n^2+16n-74=-3
3)solve each equation by factoring: 6n^2+48n+90=0

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2 acellus answer

Arace is 10 kilometers long.markers will be placed at the beginning and end of the race course and at each 500 meter mark.how many markers are needed to mark the course for the race?

This size running track is usually called a 400 meter track. however if a person ran as close to the inside as possible on the track they would run less than 400 meters in one lap. how far away from the inside border would someone have to run to make one lap equal exactly 400 meters
