H=-16t^2+-(304)/2(-16) How long does it take the projectile to reach its maximum height. Use the vertex formula to determine the time it takes the projectile to reach its maximum height.

Part 3 find the time it takes the projectile to return to the ground. Assume that the projectile starts at height H=0

The directions on a sewing pattern say to cut an extra 15% of fabric to account for error.chloe needs 0.75 yard of fabric to make a skirt, and she cuts 0.1125 yard.did chloe cut the correct amount of fabric? why or why not? a. chloe cut enough fabric because she cut the amount of fabric for the skirt. b. chloe cut enough fabric because she cut enough fabric for the skirt and the amount of extra fabric. c. chloe did not cut enough fabric because she only cut the amount of fabric for the skirt. d. chloe did not cut enough fabric because she only cut the amount of extra fabric.
