Write the equation of circle b with center B(-2,3) that passes through (1,2)

professor190 [17]

Answer:

$(x+2)^2 + (y-3)^2 = 10$

Step-by-step explanation:

The standard equation for circle is

$(x-a)^2 + (y-b)^2 = r^2$

where point (a,b) is coordinate of center of circle and r is the radius.

______________________________________________________

Given

center of circle =((-2,3)

let r be the radius of circle

Plugging in this value of center in standard equation for circle given above we have

$(x-a)^2 + (y-b)^2 = r^2 \ substitute (a,b) \ with (-2,3) \\=>(x-(-2))^2 + (y-3)^2 = r^2 \\=>(x+2)^2 + (y-3)^2 = r^2 (1)$

Given that point (1,2 ) passes through circle. Hence this point will satisfy the above equation of circle.

Plugging in the point (1,2 ) in equation 1 we have

$\\=>(x+2)^2 + (y-3)^2 = r^2 \\=> (1+2)^2 + (2-3)^2 = r^2\\=> 3^2 + (-1)^2 = r^2\\=> 9 + 1 = r^2\\=> 10 = r^2\\=> r^2 = 10\\$

now we have value of r^2 = 10, substituting this in equation 1 we have

Thus complete equation of circle is $=>(x+2)^2 + (y-3)^2 = r^2\\=>(x+2)^2 + (y-3)^2 = 10$

PLEASE HELP ME What is the measure of angle y?<br> 130°<br> 50°<br> 90°<br> 40°

QveST [7]

Answer:

m<y=50

Step-by-step explanation:

The total interior angles of a triangle is 180 degrees. This is a right triangle, the right angle measures 90 degrees. The given angle is 40 degrees.

Add 90 and 40.

90+40=130

Subtract 130 from 180.

180-130=50

m<y=50

Check:

90+40+50=180

90+90+180

180=180

If a room is 20 by 24 feet, how big is it on a floor plan where 1/2 inch represents 1 foot?

Naddik [55]

Well if you take the room being 20 x 24. Thats 480 feet. But you want how large in 1/2 inch. 1/2 inch is 1/24 of a foot. So if we take 480 feet being 1 and times it by 24. (480 x 24) You get 11,520 half inches. Brainliest would be much appreciated if you feel its deserved.
