Barnaby’s grandfather is always complaining that back when he was a teenager, he used to be able to buy his girlfriend dinner for only $1.50. a.)If that same dinner that Barnaby’s grandfather purchased for $1.50 sixty years ago now costs $25.25, and the price has increased exponentially, write an equation that will give you the costs at different times.
b.) How much would you expect the same dinner to cost in 60 years?

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.

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values

d. you cannot tell because there are no values shown.
