What is the general form of the equation of a circle with its center at (-2, 1) and passing through (-4, 1)?

Answers

Answer 1
Answer: The equation of circle is:
(x-a)^2+(y-b)^2=r^2 where C(a, b) is the center.
In order to find r you have to find the distance between C(-2, 1) and let's say A(-4, 1)

The formula for distance is:
\sqrt{ ( y_(A)-y_{C )^(2) + (x_(A)- x_(C )^(2) )
r = 2

The equation of circle is
(x+2)^2+(y-1)^2=4

I hope that this is the answer that you were looking for and it has helped you.

Determine which of the following equations define a function. For those that do not,state the reason for your answer.
x +3=0

Answers

x + 3 = 0 is not a function because it is a vertical line.

A vertical line has undefined slope because all points the line have the same x-coordinate.

A function is a relation in which no two ordered pairs have the same first component (x-values or input) and different second components (y-values or output).

Remember that a function can only take on one output for each input. Since a vertical line has the same x-coordinates for all values of y-coordinates, then it means that it is not a function.

In △PQR, if the measures of ∠Q and ∠R are 100° and 45°respectively, find the measure of ∠P

Answers

Answer:

∠ P = 35°

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180° , then

∠ P + ∠ Q ∠ R = 180° ( substitute given values )

∠ P + 100° + 45° = 180° , that is

∠ P + 145° = 180° ( subtract 145° from both sides )

∠ P = 180° - 145° = 35°
