What is the equation of the circle with center (1, −1) that passes through the point (5, 7)?

kykrilka [37]

Answer:

Option C $(x-1)^2+(y+1)^2=80$

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The distance from the center of the circle to any point on the circumference of the circle is equal to the radius of the circle

we have

(1,-1) and (5,7)

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

substitute the values

$d=\sqrt{(7+1)^{2}+(5-1)^{2}}$

$d=\sqrt{(8)^{2}+(4)^{2}}$

$d=\sqrt{80}\ units$

step 2

Find the equation of the circle in center radius form

$(x-h)^2+(y-k)^2=r^2$

where

(h,k) is the center

r is the radius

substitute

$(x-1)^2+(y+1)^2=(\sqrt{80})^2$

$(x-1)^2+(y+1)^2=80$

Why is it important to use estimation when solving problems

stellarik [79]

Well, it might not be important for most problems but..
If you're dividing, and the answer is a repeat..
You can estimate.

Example - 2.678 | You can estimate it to 2.68 and use that as an answer instead of a very long answer that's repeated.

I hope this helps.

Equation of the circle is x^2 +(y-10)^2=16. The radius of the circle is___units. The center of the circle is at ___

lubasha [3.4K]

Answer:

Radius=4 units

Centre= (0,-10)

Step-by-step explanation:

Given equation of circle is x^2 +(y-10)^2=16

Comparing it with (x-h)^2 +(y-k)^2 = r^2 ,we get,

r=4

Since, centre of a circle=(h,k)=(0,-10)

110- 37.25=72.25

72.25 divided by .20 =361.25

but since you can not drive part of a mile it would be 361 miles in one day.
