If $4000 is the principal, compounded annually at 6%per annum for five years, then-
Amount=principal *(1+rate/100)^5
=4000*(1+6/100)^5
=4000*(53/100)^5
=5352.90
Therefore, Compound Interest =5352.90-4000
=$1352.90
Please recheck the calculation.
210900 × 0.15 = 31635
210900 - 31635 = 179265
179265 is the mortgage loan
Using the power rule, the derivatives are given as follows:
a)
.
b)
.
<h3>What is the power rule for a derivative?</h3>
