In 1993, the moose population in a park was measured to be 4730. by 1997, the population was measured again to be 4330. if the population continues to change linearly.

The rate of change in population is 100 per year.

Step-by-step explanation:

Since we have given that

In 1993, the population = 4730

In 1997, the population = 4330

So, it means, population continues to change linearly.

So, the slope of population to get change would be

Hence, the rate of change in population is 100 per year.

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.
