Suppose that when your friend was born, your friend’s parents deposited $2000 in an account paying 4.5% interest compounded quarterly. What will the account balance be after 18 years?​

The account balance will be $4475.53 after 18 years.

Step-by-step explanation

Since the inital deposite is $2000, we have 2000 before the parenthases. Then we have 1+ because your friend's parents are Paying interest, which is adding. then we have to convert 4.5% by moving the decimal point over 2 places to the left and adding in zeros. So, 4.5% is now 0.045. then we divide 0.045 by 4 because they are paying quarterly. Finnally we have (4)(18) as an exponent because they are paying 4.5% interest quarterly through 18 years.

So we have

= 4475.53

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
