The cost, in dollars, of producing x yards of a certain fabric is C(x) = 1500 + 12x − 0.1x2 + 0.0005x3. (a) Find the marginal co
Flauer [41]

Answer:

(a) The marginal cost function is 12 - 0.2x + 0.0015x^2

(b) C'(500) = $287. C'(500) indicates the rate at which cost is rising with respect to production level of the fabric when x = 500.

C'(500) predicts the cost of producing the 500th yard of fabric.

(c) C'(500) = $287

The cost of manufacturing the 501st yard, C(501) = $287.6505.

C(501) is approximately the same as C'(500).

Step-by-step explanation:

(a) The marginal cost function is obtained by differentiating the cost function (C) with respect to the number of yards of fabric produced (x)

C(x) = 1500 + 12x - 0.1x^2 + 0.0005x^3

C'(x) = 12 - 0.2x + 0.0015x^2

(b) C'(x) = 12 - 0.2x + 0.0015x^2

C'(500) = 12 - 0.2(500) + 0.0015(500)^2 = $287. This means that cost is rising at a rate with respect to the production level when x = 500.

C'(500) = $287 predicts that the cost of producing the 500th yard of fabric is $287.

(c) C(x) = 1500 + 12x - 0.1x^2 + 0.0005x^3

C(501) = 1500 + 12(501) - 0.1(501)^2 + 0.0005(501)^3 = $287.6505 is approximately the same as C'(500) which is $287

How many centimeters long is a leg of an isosceles right triangle if its hypotenuse has a length of 8√2 centimeters?
andrew-mc [135]

Answer:

The leg is 8 cm long

Step-by-step explanation:

An isosceles right triangle has the length of its hypotenuse and opposite equal

Let us call the length x

From Pythagoras’ , the square of the hypotenuse equals the sum of the squares of the two other sides

Thus, we have ;

x^2 + x^2 = (8 √2)^2

2x^2 = 128

x^2 = 128/2

x^2 = 64

x= √64

x = 8 cm
