What is the equation of a circle with a center (-2, 3) and a radius r = 5?

qwelly [4]

The formula for the equation of a circle is:
(x - h)^2 + (y - k)^2 = r^2

(h, k) is the center.

So the equation would be:
(x + 2)^2 + (y - 3)^2 = 5^2
or
(x + 2)^2 + (y - 3)^2 = 25

Prove that if a quadrilateral has four equal sides and one right angle, then the quadrilateral is a square

mars1129 [50]

So lets ABCD are the sides of the square and AB=CD, AC=BD and the Angle ABC = 90 so therefore by making a diagonal we can use the SAS or SSS congruency for two triangles, so we can prove two triangles are equal and that is why the shape is square.

Need help please don't know this no links

abruzzese [7]

Answer:

$551

Step-by-step explanation:

The maximum profit is found where the derivative of the profit function is 0.

y' = -2x +62 = 0

x = 62/2 = 31

Then the maximum profit is ...

y = (-x +62)x -410

y = (-31 +62)(31) -410 = 961 -410 = 551

Assuming the profit is in dollars, the maximum profit the company can make is 551 dollars.
