The population of a city increases by 4,00 people each year. in 2025 the population is projected to be 450,000 people. what is an equation that gives the city's population p (in thousands of people) x years after 2010?
p=4x+50
p-450=4(x-15)
p-15=4(x-450)
p=4x+15

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
