A manufacturer produces bolts of a fabric with a fixed width. A quantity q of this fabric (measured in yards) that is sold is a

BigorU [14]

Answer:

$R'(20) = 2000$

Step-by-step explanation:

We are given the following in the question:

Quantity, q

Selling price in dollars per yard, p

$q=f(p)$

Total revenue earned =

$R(p)=pf(p)$

f(20)=13000

This means that 13000 yards of fabric is sold when the selling price is 20 dollars per yard.

f′(20)=−550

This means that increasing the selling price by 1 dollar per yards there is a decrease in fabric sales by 550.

We have to find R'(20)

Differentiating the above expression, we have,

$R'(p) = \displaystyle\frac{d(R(p))}{dp} = \frac{d(pf(p))}{dp} = f(p) + pf'(p)$

Putting the values, we get,

$R'(p) = f(p) + pf'(p)\\\\R'(20) = f(20) + 20(f'(20))\\\\R'(20) = 13000 + 20(-550) = 2000$

Answer:

-1.1, 6.1

Step-by-step explanation:

-2X^2+10X+14=0

(-2X^2+10X+14)/-2=0

X^2-5X-7=0

Then use the quadratic formula because you can't factor

Fill in the equations and solve. One should have the plus and the other should have the minus and that's how you get the 2 different answers.

dimaraw [331]

Answer: 30-40-50, or B

Step-by-step explanation:

Think of this equation of a right triangle. We know that the hypotenuse is 50 feet and leaning.

Since right triangles follow a formula is 3-4-5, then, 30, 40 and 50 is the answer.

he dot plot below shows 6 data points with a mean of 16. A dot plot going from 11 to 20. 1 dot is above 12, 13, 15, 17, 19, 20.

puteri [66]

Answer:

The absolute deviation at 19 is 3.

Step-by-step explanation:

The absolute and mean absolute deviation show the amount of deviation (variation) that occurs around the mean score.

Since we are only interested in the deviations of the scores and not whether they are above or below the mean score, we can ignore the minus sign and take only the absolute value, giving us the absolute deviation.

We are asked to find the absolute deviation at 19.

the given mean is 16.

Hence, the deviation is:

19-16= -3.

Hence the absolute deviation at 19 is |-3|=3.

You have a square that has a side length of $1$ centimeter. Each minute, $2$ centimeters are added to the side length. After $10

Mariulka [41]

Answer:

Difference in area of the last square and the initial square = 440 cm²

Step-by-step explanation:

Length of the side of a square = 1 cm

Area of the square = (side)² = 1 cm²

Addition of side length every minute = 2 cm

After x minutes length of each side of the square = (1 + 2x) cm

If x = 10 minutes

Length of each side of the square = [1 + 2(10)]

= 21 cm

Area of the square after 10 minutes = (21)²

= 441 cm²

Therefore, difference in area of the last square and area of the initial square

= 441 - 1

= 440 cm²
