need help.. The midpoint of GH is M(-6,-3). One endpoint is H (-4,4) Find the coordinates of endpoint G.
iren2701 [21]

Answer:

The coordinates of G are: (-8, -10)

Step-by-step explanation:

Mid point formula:

x = \dfrac{x_1+x_2}{2}\\y = \dfrac{y_1+y_2}{2}

Where,

(x,y) are the coordinates of the mid point of the points (x_1,y_1)  and (x_2,y_2).

As per question statement, we are given that:

x_2=-4\\y_2=4

and

x=-6\\y=-3

To find:

x_1 = ?\\y_1 = ?

Solution:

Let us use the mid point formula:

-6 = \dfrac{x_1-4}{2}\\\Rightarrow -12=x_1-4\\\Rightarrow x_1=-12+4\\\Rightarrow \bold{x_1=-8}

-3 = \dfrac{y_1+4}{2}\\\Rightarrow -6=y_1+4\\\Rightarrow y_1=-6-4\\\Rightarrow \bold{y_1=-10}

The coordinates of G are: (-8, -10)

A circle is centered at the point (-3,2) and passes through the point (1,5). What is the radius of the circle?
Akimi4 [234]

Answer:

5

Step-by-step explanation:

The radius is a distance on a circle from the center to a point on the circle.

We have both of these points describe here in this definition.  Using the distance formula will give us the radius.

\sqrt{(x \text{ difference })^2+(y \text{ difference})^2

The difference between 1 and -3 is 1-(-3)=4.

The difference between 5 and 2 is 5-2=3.

\sqrt{4^2+3^2}

\sqrt{16+9}

\sqrt{25}

What is 0.03 out of 1 as a percent?
BigorU [14]
When trying to find a percent, it is best to multiply everything by 100 (as a percentage is out of 100). 0.03*100= 3 and 1*100=100. Therefore, 0.03 as a percent is 3% Hope this helps :)
