Do this please!!! It's an easy exercise of finding the volume of a pyramid

A) if $50000 is invested in a bank account that pays 9.3% of interest compounded on a six-monthly basis, how much money will be in the account after 3 and 12 years? b) if matusalen's father had put $2.0 in the bank when he was born and there, how long would matusalen have had to his death (969 years later) if the interest was 7% per year composed each month and weekly?

Which statement justifies why angle ebc measures 90?

You deposit $5000 each year into an account earning 3% interest compounded annually. how much will you have in the account in 30 years?
