If you would like to calculate 7 * 3/4, you can do this using the following steps:
7 * 3/4 = 21/4 = 5 1/4
The correct result would be 21/4.
Answer:
The circle's centre is at the position (3, 5), and it has a radius of 2
Step-by-step explanation:
First let's put it in a useful format by completing the squares:
x² + y² - 6x - 10y + 30 = 0
x² - 6x + y² - 10y = -30
x² - 6x + 9 + y² - 10y + 25 = -30 + 9 + 25
(x - 3)² + (y - 5)² = 4
This tells us that the centre position is (3, 5) and the radius is √4, or 2
True, because of the Triangle Inequality Theorem.
To test if you could construct a triangle, make sure the following inequalities are true.
9 + 4 > 11
9 + 11 > 4
4 + 11 > 9.
