<h3>Answer:  2x/15</h3>

T = total amount of money = (14x^2)/15

y = amount of money each person receives

n = number of people

y*n = T

y*7x = (14x^2)/15

y = (1/(7x))*(14x^2)/15 .... multiply both sides by 1/(7x)

y = 2x/15

Suppose it has been determined that the sales at Ewing Gallery decline after the end of an advertising campaign, with daily sale
gtnhenbr [62]

Answer:

$1050 is the daily sales 5 days after the end of the campaign.

Step-by-step explanation:

We are given the following in the question:

S(x)= 2100(2^{-0.2x})

where S is the daily sales in dollars and x is the number of days after the campaign ends.

We have to find the value of the daily sales 5 days after the end of the campaign.

We put x  = 5 in the equation:

S(5)= 2100(2^{-0.2(5)}) = 2100(2^{-1}) = 1050

Thus, $1050 is the daily sales 5 days after the end of the campaign.

Find the numbers b such that the average value of f(x) = 4 + 10x − 6x2 on the interval [0, b] is equal to 5.
Tju [1.3M]

Answer:

  b = (5±√17)/4 ≈ {0.2192, 2.2808}

Step-by-step explanation:

The average on the interval is found from the integral ...

  \frac{1}{b}\int\limits^b_0 {(4+10x-6x^2)} \, dx =\frac{1}{b}(4b+5b^2-2b^3)\\\\=-2b^2+5b+4

We want the value of this integral to be 5, so we want to find b such that ...

  5 = -2b^2 +5b +4

  2b^2 -5b +1 = 0

  b^2 -5/2b = -1/2

  b^2 -5/2b +25/16 = -1/2 +25/16

  (b -5/4)^2 = 17/16

  b = (5±√17)/4

The average value of f(x) is 5 on the intervals ...

  [0, (5-√17)/4] and [0, (5+√17)/4]
