Afirecracker shoots up from a hill 140 feet high, with an initial speed of 100 feet per sound. using the formula h(t) = -16t2 + be + s, approximately how long will it take the firecracker to hit the ground? a.) 5 secs b.) 7 secsc.) 9 secsd.) 11 secs

Most likely C it would take 9 secs.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
