What is the general form of the equation of a circle with its center at (-2 ,1) and passing through (-4, 1)
Jlenok [28]
The equation of a circle is (x - h)² + (y - k)² = radius²
where the center is represented by (h, k).

So to plug in:
(x - (-2))² + (y - 1)² = radius²
(x + 2)² + (y - 1)² = radius²

To find the radius, you can do the distance formula OR (and I suggest this one) use common sense. The center and point given have the same Y-value meaning they are in a horizontal line. Because of this, you can just find the distance between them (AKA your radius) by doing the absolute value of their difference:

|- 4 - (-2)| = |- 4 + 2| = |-2| = 2

Just to show order doesn't matter:
|- 2 - (-4)| = |- 2 + 4| = |2| = 2

Your radius is 2. Plug this into your equation and simplify.

(x + 2)² + (y - 1)² = (2)²

Your answer is:
(x + 2)² + (y - 1)² = 4

Answer:

Question 16: 44 inches

Question 18: 10, 24, 26

Step-by-step explanation:

<em><u>Question 16:</u></em>

Pythagoras Theorem: c^2 = a^2 + b^2, where c is the hypotenuse and the longest side.

125^2 = 117^2 + b^2

15,625 = 13,689 + b^2

15,625 - 13689 = b^2

1936 = b^2

√1936 = b

44 = b

<em><u>Question 18: </u></em>

Pythagoras Theorem: c^2 = a^2 + b^2, where c is the hypotenuse and the longest side. You have to try all the possibilities. The ones that match are the lengths.

The answers are 10, 24, 26

c^2 = a^2 + b^2

26^2 = 10^2 + 24^2

676 = 100 + 576

676 = 676
