Answer:
The interest rate was of 5.5% a year.
Step-by-step explanation:
The compound interest formula is given by:
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit year and t is the time in years for which the money is invested or borrowed.
In this question, we have that:
We have to find r.
Taking the square root from both sides to isolate r.
The interest rate was of 5.5% a year.
You plug in a 3 wherever you see an x
2x^3-4x^2+6x
2(3)^3-3(3)^2+6(3)
2(27)-3(9)+18
54-27+18
27+18
=45
Hope this helps
