Mary wants to borrow $42 000 for two years. Bank A will charge her 4% simple interest. Bank B will charge her 4% interest but
the interest will be compounded every six months.
a) Calculate the interest Mary will pay to Bank A.
b) Calculate the interest Mary will pay to Bank B.
c) Which is the better deal for Mary, and how much will she save?

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.

it would be 0.18 because when the other choices are converted they equal those two numbers.   hope this !

answer is b chief get it right
