Acircle has its center at (−2, 5) and a radius of 4 units. what is the equation of the circle? (1 point) (x 2)2 (y − 5)2 = 16 (x 2)2 (y 5)2 = 16 (x 2)2 (y − 5)2 = 4 (x − 2)2 (y 5)2 = 4

Step-by-step explanation:

We have been given that a circle has its center at (−2, 5) and a radius of 4 units. We are asked to write the equation of the circle.

We know that standard equation of circle is in form , where, (h,k) represents vertex of circle and r represents radius of circle.

Upon substituting coordinates of vertex and in above equation, we will get:

Therefore, the equation of our given circle would be .

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.

step-by-step explanation:

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
