Find the equation of a circle with a center at (7, 2) and a point on the circle at (-2, -5).
KatRina [158]

Answer:

(x-7)^2 + (y-2) ^2 = 130

Step-by-step explanation:

We need to find the length of the radius

the length of the radius is found by using the distance formula

r = sqrt(  ( -2-7)^2+( -5 -2)^2)

    sqrt(  ( -9)^2+( -7)^2)

    sqrt( 81+49)

    sqrt(130)

The formula for a circle is

(x-h)^2 + (y-h) ^2 = r^2

where (h,k) is the center and r is the radius

(x-7)^2 + (y-2) ^2 = 130

One year, the population of a city was 330,000. Several years later it was
goblinko [34]

Answer:

18%

Step-by-step explanation:

Express the ending population as a percentage of the starting population:

270000 divided by 330000=0.82

0.82 *100=82

subtract from the 100% we started with to get the percent decrease:

100% - 82% = 18
