A circle is described by the equation x2 y2 14x 2y 14 = 0. what are the coordinates for the center of the circle and the length
bearhunter [10]

Answer:

length is (-7,-1) and radius is 6

Step-by-step explanation:

We are given the expression of the equation of a circle that is

x2 + y2 + 14x + 2y + 14 = 0.

Using completing the squares:

x2 + y2 + 14x + 2y + 14 = 0(x+7)^2 + (y+1) ^2 = -14 + 49 + 1(x+7)^2 + (y+1) ^2 = 36 center thus is at (-7,-1) and the radius is equal to square root of 36 equal to 6.

A circular race track has a radius of 200 feet a car drives 50 laps around the track approximately how many miles does the car t
bazaltina [42]

Answer:

  11.9 miles

Step-by-step explanation:

The length of the track is ...

  C = 2πr = 2π(200 ft) = 400π ft

Then the length of 50 laps will be ...

  50C = 50·(400π ft) = 20,000π ft ≈ 62,831.9 ft

The number of miles (m) this is can be found from ...

  m(5280 ft) = 62,831.9 ft

  m = 62,831.9/5280 ≈ 11.90 . . . . miles

50 laps is about 11.9 miles.
