<h2>Answer:</h2>

The marginal cost when x=8 is:

                          375

<h2>Step-by-step explanation:</h2>

We know that the marginal function for a cost function C(x) at x=a

is given by:

   C'(x) at x=a

Here we have the cost function C(x) as:

C(x)=110+7x-x^2+2x^3

Now we find the derivative of C(x) with respect to x.

i.e.

C'(x)=0+7-2x+6x^2

( Since,

\dfrac{d}{dx} x^n=nx^{n-1}  )

C'(x)=7-2x+6x^2

Hence, we get:

C'(8)=7-2\times 8+6\times (8)^2\\\\i.e.\\\\C'(8)=7-16+384\\\\C'(8)=375

On a flight from New York to London, an airplane travels at a constant speed. An equation relating the distance traveled in mile
lions [1.4K]

Complete question :

On a flight New York to London an airplane travels at a constant speed. An equation relating the distance traveled in miles d to the number of hours flying t is t= 1/500d. How long will it take the airplane to travel 800 miles?

Answer:

1.6 hours

Step-by-step explanation:

Given the function :

Time t taken for flying distance d is given by:

t = 1/500 * d

Tine taken to fly 800 miles;

d = 800 miles

t = 1/500 * (800)

t = 800 / 500

t = 1.6

Hence, time t = 1.6 hours

A rectangular flower bed that is 5 ft long and 4 feet wide is surrounded by a square lawn that is
mr Goodwill [35]

Answer:

124 ft2

Step-by-step explanation:

The yard is a 12ft square so the length and width would both be 12ft. You multiply the length and width of the yard to get the area of the yard so 12x12=144. You have the length and width of the flower bed so 5x4=20. Once you have the area of both you can subtract the area the flower bed takes up of the lawn. 144-20=124 ft2.

Find 30% of 70<br> a. 21<br> b. 36<br> c. 40
gtnhenbr [62]
A is your answer

We can cross multiply using x/70=30%/100

Solving it we get:
100x=2100 (70 times 30)
x=21


So we get a, 21 as your answer.

I hope this helped!
