Answer:
(a)
(b)
(c)R'(5400)=$394
Step-by-step explanation:
Given that x is the quantity demanded and the speaker's unit price (in dollars) is p where:
p = −0.02x + 610 (0 ≤ x ≤ 20,000)
(a)Revenue function R.
Revenue = Price X Quantity Demanded
Therefore:
R(x)=xp
(b)Marginal revenue function R'(x)
If
Then, the marginal revenue function
(c)We want to compute R'(5,400)
From the above, we can infer that the revenue that will be generated on the sales of the 5401st item is $394.
Answer:
average speed of hiker is 2.4 mph
Step-by-step explanation:
here is the solution : -

average speed of hiker is 2.4 miles per hour
20 quarts is less than 10 gallons because there are 4 quarts to a gallon which make 20 quarts 5 gallons for it to be 10 gallons it would have to be 40 quarts
This sequence starts with an initial set; let’s call it s1. This set contains 20 cans, and every set following would have two less cans than the last set. So,
s1=20
s2=s1-2=18
s3=s2-2=16
•
•
•
s9=s8-2=4
How many cans in the display represents the value of each set added together, so we can denote this as
s1+s2+s3+...+s9
and replacing with values:
20+18+16+...+4 = 108
The number of cans in the display equals 108.
(The set notation seems weird, but by practicing this application now, the Calculus version will seem easier.)
