Marsha and jan both invested money on march 1, 2007. marsha invested $5,000 at bank a where the interest was compounded quarterly. jan invested $3,000 at bank b where the interest was compounded continuously. on march 1, 2011, marsha had a balance of $6,484.65 while jan had a balance of $3,821.99. what was the interest rate at each bank? (round to the nearest tenth of a percent.)

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

-1/4 > -1 2/3. -1/4 is greater than -1 2/3 because it is closer to 0 on the number line.
