The area of square LMNP is 50

<h3>What is a circle?</h3>

A circle is the locus of points equidistant from a fixed point which is known as the center of the circle.

A circle is defined if the center and the radius is known.

Analysis:

Perimeter of a circle = 2πr

Given perimeter = 10π

2πr = 10π

2r = 10

r = 10/2 = 5

r = MO

so the diagonal of the square is actually the diameter of the circle = 5+5 = 10

To find the side, x of the square the diagonal and the sides form a right-angled triangle, by  Pythagoras, 10^{2} = x^{2} + x^{2}

2x^{2} = 100

x^{2} = 100/2 = 50

Also area of square is x^{2} = 50

In conclusion, the area of square LMNP is 50

The x-coordinate in the solution of the system of equations  y = -2/3x and 4x - 9y = -40 is -4

<h3><u>Solution:</u></h3>

<em><u>Given that system of equations are:</u></em>

y = \frac{-2}{3}x  ------- eqn 1

4x - 9y=-40 ------ eqn 2

We have to solve the above given system of equations and find the x - coordinate

<em><u>Substitute eqn 1 in eqn 2 and solve for "x"</u></em>

4x - 9(\frac{-2}{3}x) = -40\\\\4x + \frac{18x}{3} = -40\\\\12x + 18x = -120\\\\30x = -120\\\\x = \frac{-120}{30} = -4

x = -4

Thus the x-coordinate in the solution of the system of equations is -4

The DingGnat Doorknob Company intends to sell a new line of square doorknobs. The price-demand function is p ( x ) = 48.5 − 0.09
pickupchik [31]

Answer:

a. 135 doorknobs

b. R(x) = 48.5x-0.09 x^2

Step-by-step explanation:

The price-demand function is:

p(x) = 48.5-0.09 x

a. At a price of $36.30, the number of doorknobs sold, 'x' is:

p(x) = 48.5-0.09 x\\36.30 = 48.5-0.09 x\\x= \frac{48.5-36.30}{0.09}\\x=135.55

Rounding it down to the nearest whole unit, the company can sell 135 doorknobs at $36.30

b. Revenue is the product of the price, p(x), by the demand, x. Therefore, the Revenue function is:

R(x) = x*p(x)=x(48.5-0.09 x)\\R(x) = 48.5x-0.09 x^2
