Answer:

Looking at the question and goin step by step

we get to know that equation formed wud be ->

product of nine and a number - 9*x = 9x

added to 6 => 9x+6

gives us 24

9x + 6 = 24

now 9x = 18 and x = 18/9 = 2

and now keeping x value = 9 *(2)+6 we get 18+6 = 24

so lhs = rhs = 24

9x+6=24 option a

Which equation represents inverse variation between x and y?

postnew [5]

Inverse variation means

When the value of x increases the value of y decreases.

When the value of x decreases the value of y increases.

So for an inverse variation we have the expression

$y=\frac{k}{x}$

$x=\frac{k}{y}$

The expression which represents this condition is

$x=-\frac{15z}{y}$

Hence option b) or the second option is the right answer.

What is the arc length of the shaded region to the nearest tenth?

Maslowich

Answer:

285

Step-by-step explanation:

The total amount of degrees in a circle is 360, we know that the un-shaded portion of the circle is 90 degrees this means that the shaded portion has 270 degrees.

We also know that the area of the circle is $\pi r^{2}$ but we are finding a portion of that, therefore we would need to multiply it by $(\frac{270}{360} )$ . The radius is also given which is 11.

Area of the shaded region = $(\frac{270}{360}) * \pi 11^{2}$ = 285

An aircraft manufacturer wants to determine the best selling price for a new airplane. The company estimates that the initial co

Ad libitum [116K]

Answer:

The cost function is simply the initial cost plus the manufacturing cost.

C(x)=500+20x-5x^3/4+0.01x^2

The demand function was given to us.

p(x)=320-7,7x

The revenue function is simply x multiplied by the demand function.

R(x)=xp(x)=320x-7.7x^2

We find that when 20 planes are produced, that profit is currently maximized

We know that to maximize profit, marginal revenue must equal marginal cost.

C'(x)=20-15/4x^-1/4+0.02x

R'(x)=320-15.4x

x=19,57

We find that when 20 planes are produced, that profit is currently maximized.

Step-by-step explanation:

An aircraft manufacturer wants to determine the best selling price for a new airplane. The company estimates that the initial cost of designing the airplane and setting up the factories in which to build it will be 500 million dollars. The additional cost of manufacturing each plane can be modeled by the function: , where x is the number of aircraft produced and m is the manufacturing cost, in millions of dollars. The company estimates that if it charges a price p (in millions of dollars) for each plane, it will be able to sell planes.

(a) Find the cost, demand, and revenue functions.

(b) Find th eproduction level and the associated selling price of the aircraft that maximizes profit.
