On a coordinate plane, a circle has a center at (8, 9). Concentric circles are circles with the same center but different radii.

Which equations represent concentric circles along with the circle shown in the graph? Check all that apply. x2 + y2 = 25 (x – 8)² + (y – 9)² = 3 (x – 8)² + (y – 9)² = 14 (x – 8)² + (y + 9)² = 3 (x + 8)² + (y + 9)² = 25 (x + 9)² + (y + 8)² = 3

Answer:

  • (x – 8)² + (y – 9)² = 3
  • (x – 8)² + (y – 9)² = 14

Step-by-step explanation:

The equation of a circle with center (h, k) and radius r is ...

  (x -h)² +(y -k)² = r²

Circles concentric with one having its center at (8, 9) will have equations of the form ...

  (x -8)² +(y -9)² = r²

The offered answer choices that have this form are ...

  • (x – 8)² + (y – 9)² = 3
  • (x – 8)² + (y – 9)² = 14

Use compatible numbers to find two estimates 1322 divided by 18
prisoha [69]
Compatible numbers is used to find estimate to a sum. The numbers are chosen because its 'simplicity' when they are multiplied, divided, added or subtracted.

Estimate one:

We can decrease the value 1322 to 1320 and 18 to 15
Then do the sum = 1320÷15 = 88
This estimate is not far from the actual answer 1322÷18 = 73.44..

Estimate two:

We can increase 1322 to 1330 and 18 to 20
Then do the sum 1330÷20=66.50
This estimate is also not far from the actual answer 73.44...
