Answer:

£30

Step-by-step explanation:

Since the ratio of Donatella and Annasara's amount is in the ratio 4:5,

Let's say Donatella and Annasara have 4x and 5x of money.

Since Annasara has £6 more than Donatella, we can say,

5x = 4x + £6

or, 5x - 4x = £6

or, x = £6

Hence,

Amount that Annasara has = 5x

 = 5*£6

Recall Marginal Cost is the derivative of Total Cost, and Fixed Cost is the cost of producing zero units.

olga nikolaevna [1]

Answer:

The total cost of producing 91 units of ACME rocket fuel is $3999.99.

Step-by-step explanation:

The Marginal Cost is given by the following function

$MC(q) = 200*(q+9)^{-5}$

The total cost function is the integrative of the marginal cost function. So:

$TC(q) = \int {MC(q)} \, dq$

$TC(q) = \int {200*(q+9)^{-5}} \, dq$

$TC(q) = -50*(q+9)^{-4} + K$

In which K, the integrative constant, is the fixed cost. So $K = 4000$ .

1. Find the total cost of producing 91 units of ACME rocket fuel.

This is TC(91).

$TC(91) = -50*(91+9)^{-4} + 4000 = 3999.99$

The total cost of producing 91 units of ACME rocket fuel is $3999.99.

Find the area of the circle with the given radius or diameter. Use pi = 3.14. d = 13 A=?

GuDViN [60]

Hello!

The formula for finding area of a circle is: π · r²

Diameter is 2x the radius. To find the radius when the diameter is given, divide the diameter by 2.

The diameter is 13. 13 ÷ 2 = 6.5

r = 6.5
6.5² = 6.5 × 6.5 = 42.25

π = 3.14

Multiply 3.14 by 42.25 to get the area

3.14 × 42.25 = 132.665

The area of the circle is 132.665 sq. units, which is the last option.
