Answer:
<em>(x - 2)^2 + (y + 1)^2 = 26</em>
Step-by-step explanation:
A circle with center O(2, -1) that passes through the point A(3, 4).
=> The radius of this circle is OA which could be calculated by:
OA = sqrt[(3 - 2)^2 + (4 - (-1))^2] = sqrt[1^2 + 5^2] = sqrt[26]
The equation of a circle with center O(a, b) and radius r could be written as:
(x - a)^2 + (y - b)^2 = r^2
=> The equation of circle O above with center O(2, -1) and radius = sqrt(26) is shown as:
(x - 2)^2 + (y - (-1))^2 = (sqrt(26))^2
<=>(x - 2)^2 + (y + 1)^2 = 26

Answer:
-150 + 300 - 550 + 150 +50 = -200
Step-by-step explanation:
I rounded to the nearest tens place for each number.
Answer:
5 goes into 100 twenty times, so 20% is the answer

Answer:
Step-by-step explanation:
To make them consecutive, means they have to be one after the other.
You assume one of the numbers are n, to make the other integers consecutive you add 1 then 2 then 3.
A reciprocal just flips the fraction
1. 
2.
3. Before it is flipped it is 
but it turns into
