Answer:
The center of this circle is at 
. The radius of this circle is 
.
Step-by-step explanation:
A circle with center 
and a radius of 
(
) could be expressed as:
.
(In other words, a point is on this circle if and only if the distance between that point and the center is equal to the radius.)
Rearrange this equation using binomial expansion to match the equation given in this question:
.
.
The equation in this question is:
.
Match up the coefficients of 
and 
in the two equations.:
- Coefficient of :
. - Coefficient of :
.
Thus, 
and 
.
The constants of the two equations should also match up:
.
Substitute in as well as and solve for :
.
(since .)
Therefore, the center of this circle is . The radius of this circle is .
Answer:
1/24
Step-by-step explanation:
1/3÷ 8
Copy dot flip
1/3 * 1/8
1/24
The greatest 3 digit number divisible by the 8, the 10, and the 12 is 960. The simplest way of finding the number is to multiply all the divisible factor which is the 8, the 10, and the 12 that results in 960 (8*10*12). If this multiply operation results in more than 3 digit number, therefore we must analyze the factor of the result and eliminate it.
Answer:
y = 2; distance is 4 units
Step-by-step explanation:
Line y = 2
Because the y- coordinate is the same, only horizontal movement from -1 to -5..
Which is 4 units
Answer:
9/12
Step-by-step explanation:
You have to divide 36 by 4 to get 9 and then divide 48 by 4 and you will get 12.
