21. A cricket, getting stalked by a hungry bearded dragon, jumps at an initial speed of 10 inches per second. The resulting quadratic model of h = -10t2 + 75t, where h is the height in inches and t is the time in seconds. In how
many seconds will the cricket land back on the ground after the first jump? Show all work and write your answer in
complete sentences with proper units labeled.

a box 3 3/4 feet long or 4+ feet.

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
