The population P(in thousands) of Austin, Texas, during a recent decade can be approximated by y=494.29(1.03)t, where t is the number of years since the beginning of the dedicate. Tell whether the model represents exponential growth or decay and how you know.

Identify the annual percent increase or decrease in population (this will just be a percentage).

Estimate when the population was about 590,000.

i do not know the answer i am sorry

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !

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.

answer: c
