So first of all you can find x and y because all triangles have interior angles that add up to 180 degrees.

X= 10 degrees
Y= 60 degrees

Looking at the options, we see that the first statement is true. And if the angles are not equal, the triangles are not able to be similar.

Suppose the weekly revenue for a company is given byr: 202400p wherep is the price of their product. What is the price of their

Rudiy27

Answer:

(a) The price for a revenue of $18,750 is $239.2.

(b) They sold 710 colonial houses and 2130 ranch houses

Step-by-step explanation:

(a) If the weekly revenue is defined as

$r=2p^2+400p$

then the price must be calculated as:

$r=2p^2+400p=18750\\\\2p^2+400p-18750=0$

The roots of this function are

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}=\frac{-400 \pm \sqrt{400^2-4*2*(-18750)}}{2*2}\\ \\x=\frac{-400 \pm 556.78}{4}\\ \\x_1=-39.2\\x_2=239.2$

The first root is negative, so it is not a real solution. So the second root is the answer.

The price for a revenue of $18,750 is $239.2.

(b) Last year they sold three times as many ranch models (Hr) as they did colonial models (Hc):

$H_r=3*H_c$

The total amount of houses sold (colonial + ranch) is 2840

$H_c+H_r=2840\\H_c+3*H_c=2840\\4*H_c=2840\\H_c=2840/4=710\\\\H_r = 3*H_c=3*710=2130$

The diameter of a circle has endpoints of (2, 5) and (-4, 13). What is the correct equation of this circle? Pls explain and I wi

Bezzdna [24]

Answer:

Option 4

Step-by-step explanation:

Midpoint of the diameter is the center.

<u>Use midpoint formula to determine the coordinates:</u>

x = (2 - 4)/2 = -1
y = (5 + 13)/2 = 9

<u>Find the radius using the midpoint and one of the endpoints and the distance formula:</u>

r = $\sqrt{(-1 - 2)^2 + (9 - 5)^2} = \sqrt{9+16} = \sqrt{25} = 5$

<u>Use the equation of the circle:</u>

(x - (-1))² + (y - 9)² = 5²
(x + 1)² + (y - 9)² = 25

Correct choice is 4
