Water is released into a tank at the rate r(t) = 5 + √ t ft3/min at time t (in minutes). at time t = 1, there is 12 ft3 of water in the tank.

(a) evaluate z 6 1 r(t) dt, rounding your answer to two decimal places.

(b) in the context given above, what does the value in part (a) tell us?

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
