Suppose that for a company manufacturing calculators, the cost, revenue, and profit equations are given by Start 1 By 3 Matrix 1st Row 1st Column Upper C equals 90 comma 000 plus 40 x comma Superscript 2nd Column Upper R equals 200 x minus StartFraction x squared Over 20 EndFraction comma 3rd Column Upper P equals Upper R minus Upper C Superscript EndMatrix where the production output in 1 week is x calculators. If production is increasing at a rate of 500 calculators per week when production output is 4 comma 000 calculators. Find the rate of increase (decrease) in cost, revenue, and profit.

Step-by-step explanation:

The cost, revenue, and profit equations for a company manufacturing calculators are given below:

When  Production output x=4000

Change in Cost

Cost, C=90000+40x

Change in Revenue

Change in Profit

Therefore, when production output is 4000 and increasing at a rate of 500 calculators per week,

answer for #1 is c

answer for #2 is d

can i get brainliest

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
