Which point does not lie on the circle centered at (3,2) with radius 5
patriot [66]

The point which does not lie on the circle centered at (3,2) with radius 5 is given below.

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (3, 2) and r = 5,

hence

(x - 3)² + (y - 2)² = 25 ← equation of circle

If an ordered pair lies on the circle then it satisfies the equation, if not then it does not lie on the circle.Substitute the coordinates of the points into the left side of the equation of the circle and check validity.

1

(0 , 6) : (0 - 3)² + (6 - 2)² = 9 + 16 = 25 ← lies on circle

2

(3, - 3) : (3 - 3)² + (- 3 - 2)² = 0 + 25 = 25 ← lies on circle

3

(- 2, 2) : (- 2 - 3)² + (2 - 2)² = 25 + 0 = 25 ← lies on circle

4

(3, 0) : (3 - 3)² + (0 - 2)² = 0 + 4 = 4 ≠ 25 ← not on circle

Describe the mental math steps you would use to find 7(42) (this is the distributive property by the way. :] )
Katarina [22]

Answer:

multiply 7 by 42

= 294

42 x 7 can be done as mental math, but that is challenging for some people.

lana66690 [7]
We know that the building is 256.25 m long and that a ratio is 25 meters to 1 inch.
We have to divide the length of a building to 25:
256.25 : 25 = 10.25
Answer: The building will be 10.25 inches long in the sketch.
