The raidius of the circle is r=___The equation of the circle in standard form____

Schach [20]

step 1

Find the radius of the circle

To find out the radius, calculate the distance between the center and any point that lie on the circle

so

(-2,3) and (-2,0)

Its a vertical distance

so

r=3-0=3 units

step 2

we have the radius r=3 units and the center (-2,3)

the equation of the circle is

$\begin{gathered} (x+2)^2+(y-3)^2=3^2 \\ (x+2)^2+(y-3)^2=9 \end{gathered}$

What type of conic is given by the equation 4x^2+9y^2=36

zvonat [6]

Answer:

This is equation of ellipse

Step-by-step explanation:

we are given

$4x^2+9y^2=36$

We can see that right side is 36

so, we can make right side as 1 by dividing both sides by 36

$\frac{4x^2+9y^2}{36} =\frac{36}{36}$

$\frac{4x^2+9y^2}{36} =1$

$\frac{4x^2}{36}+\frac{9y^2}{36} =1$

we can simplify it

$\frac{x^2}{9}+\frac{y^2}{4} =1$

we can rewrite it as

$\frac{x^2}{3^2}+\frac{y^2}{2^2} =1$

now, we can compare it with standard equation of ellipse

$\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2} =1$

we can see that both equations are similar

so, this is equation of ellipse

Step-by-step explanation:

8( -x - 7) > 16

-8x - 49 > 16

+ 49 + 49

-8x > 65

x > 8.125 or 8 & 1/8

Is 1 3/23 a rational number

UkoKoshka [18]

Answer:

Yes

Step-by-step explanation:

In mathematics rational means "ratio like." so a rational number is one that can be written as the ratio of two integers. 1 3/23 can be converted into 26/23, which is a ratio, therefore, 1 3/23 is a rational number.

Hope this helps!
