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.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

can you rephrase the question ? it is unclear : -)
