The circle with center (1,6) and radius 3 has equation .
(Type equation.)
an

(x-1)^2+(y-6)^2=9

Step-by-step explanation:

You use the center to get the left part of the equation and the radius to get the right.

The standard equation of a circle is

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

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

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
