Answer:
The net profit per bike is 150-40= 120. Hence to break even, the store needs to profit more than the operating cost of the store. 3840/ 120= 32. The store needs to sell 32 bicycles each month to break even.
Answer:
5.428571
Step-by-step explanation:
take the fraction and divide that:
then just add 5:
5 + 0.428571 = 5.428571
or...
convert the mixed fraction to improper fraction:
divide like normal:
Answer:
-28x-41
Step-by-step explanation:
6*5x-6*8
30x-48
2x+7-30x-48 = 2x-30x+7-48 = -28x+7-48 = -28x+(-41)= -28x-41
It's hard to type and hard to read the "inverse tangent" function, as you've seen (above).
So, use "arctan x" instead.
Then the problem becomes: "differentiate cos (arctan x)."
You must apply first the rule for differentiating the cosine function, and next apply the rule for differentiating the arctan function:
(d/dx) cos (arctan x) = - sin (arctan x) * [1/(1+x^2)]
