P dollars is invested at annual interest rate r for 1year If the interest is compounded semiannually then the polynomial P(1+r/2)^2 represents the value of the investment after 1 year. rewrite the expressions without parentheses evaluate the polynomial if P=5670 and r=3.5%
looks like you have to do ...
5670(1.0175)^2
still confused
What part of Reiny's answer don't you understand?
In order for me to understand I need step by step explanations.
5670(1.0175)^2
1. Multiply: 5670(1.0175)
2. Square the product.
actually the squaring of 1.0175 has to be done first
5670(1.0175)^2
= 5670(1.03530625
= = $5870.19 , assuming it is in dollars
Thanks.
I forgot PEMDAS.
