Which equation represents a circle with the same center as
the circle shown but with a radius of 2 units?

o (x-4)2 + (y – 5)2 = 2
o (x-4)2 + (y - 5)2 = 4
o (x - 5)2 + (y – 4)2 = 2
o (x - 5)2 + (y – 4)2 = 4

Since the example circle is not shown, I can not answer thoroughly, but I will try my best.

The equation of a circle: (x - h)² + (y - k)² = r², where (h,k) is the center and r is the radius of the circle.

This means that for the radius to be two units, the right side of the equation is 2² = 4. So either B or d can be right.

Depending on the center of the given circle, we could narrow down to our final answer. If the center is (4,5), B is right, and if (5,4) is the center, D is right.

6 meters

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
