Answer:
30 yrs
Step-by-step explanation:
SI = PRT/100
T = I × 100/PR
= 9000×100/1500×20
= 900000/30000
= 30 yrs
we have

Complete the square. Remember to balance the equation by adding the same constants to each side



Rewrite as perfect squares

remember that

Square root both sides





Simplify



therefore
<u>the answer is</u>


The given polynomial expressed as partial fraction is 5x^3 + 9/x
<h3>Polynomial function and partial fractions</h3>
Polynomial function are function that have a leading degree of 3. Given the expression below;
f(x) = (5x^4+9)/x
Applying partial fraction
Since the part fraction means separating the fraction into two parts, hence;
f(x) = 5x^4/x + 9/x
Simplify
Since there is value of x at both numerator and denominator, it will cancel out to have
f(x) = 5x^3 + 9/x
From the result, we can see that p(x) = 5x^3 and k = 9
Hence the given polynomial expressed as partial fraction is 5x^3 + 9/x
