Hi.
your answer is 1/3, or 2/6, or 3/9, or 4/12, etc.
hope this helps!!!
You will need to use this formula:
Years = log (total/principal) / n * log (1 + (rate / n))
where "n" is the number of compounding periods per year.
Years = log (9,000/4,790.23) / n * log (1 + (.038 / n))
Years = log (

<span>
1.8788241901
</span>
</span>
</span>
) / 2 * log (1.019)
Years = 0.27388614314 / 2 * 0.0081741840064
Years = 0.27388614314 /

Years =

Positive correlation the more years of education the more you'll earn
Step-by-step explanation:
(a-b)^2=(a^2-2*a*b+b^2)
4*(x^2-2x+1)-9=4x^2-8x+4-9=4x^2-8x-5
if you have to calculate the Δ
there is it: 4x^2-8x-5=0
Δ=b^2-4*a*c=64-4*4*(-5)=64+80=144
-b±Δ/2*a=8±12/8=
=8+12/8=20/8|:4=5/2
=8-12/8=-4/8|:4=-1/2
