Mark invests $2,243 in a retirement account with a fixed annual interest rate of 3% compounded continuously. What will the account balance be after 15 years?

You start by multiplying 2,243 times 0.03(The representation of 3% as a decimal)
After you get 67.29, you multiply that by 15.
So the answer is $1009.35 in interest rate in 15 years

In a right-angled triangle: 1- the hypotenuse is the longest side2- we can apply pythagorean rule which states that: (hypotenuse)^2 = (side1)^2 + (side2)^2for the given triangle,longest side is 15 cm  side1 = 9 cmside2 is 12 cm  to check whether the triangle is right-angled or not,compare (15)^2 to the summation of (9)^2 and (12)^in other words, compare 225 to the summation of 81 and 144if they are both equal, then the triangle is right-angles, otherwise, it is not.you haven't provided the diagram showing her work, so i cannot tell the choice. however, apply my explanation to the question you have.
