<u>Answer: </u>
Sum of the roots of the polynomial
<u>Solution:</u>
The general form of cubic polynomial is ---- (1)
If we have any cubic polynomial having roots
Sum of roots =
---(2)
From question given that,
--- (3)
On comparing equation (1) and (3), we get a = 1, b = 2, c = -11 and d = -12
Hence the sum of roots using eqn 2 is given as,
=
= -2
Hence the sum of the roots of the polynomial
Answer:
APY = 0.04 or 4%
Step-by-step explanation:
Given the annual percentage rate of 3.5% that is compounded quarterly, and a principal of $6,500:
We can use the following formula to solve for the annual percentage yield (APY):
where <em>r</em> = interest rate = 3.5% or 0.035
<em> n</em> = number of compounding periods per year = 4
We can plug in the values into the equation:
APY = 1.03546 - 1
APY = 0.04 or 4%
