Using exploration data the management of an oil company estimates that over a period of 20 years oil can be pumped from a west texas oil field at a rate given by r(t) = 8t 4t 2 + 7 stone (ins278) – hw32 – clark – (52400) 2 where r(t) is the production rate (measured in hundreds of barrels per year) t years after pumping begins. determine the number of barrels that will be produced during the first 5 years of production.

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
