Question 23009: I need help because i am doing this w/o my book. Please and thank you. the question says Find the zero's of the polynomial function. f(x)=2(x-5)(x-6)^3
I have two more questions and that is it.The next one says use the correct compound interest formula A=P[1+r/n]^nt or A=Pe^rt to solve I don't know what they mean can u tell me please. Using that it says Find the accumulated value of an investment of $10,000 at 4% compounded annually for 17yrs.
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! Zeros of the polynomial function are the points where f(x) = 0. What values of x will zero out the equation? Answer: x= 5 and x= 6. These are also the x-intercepts.
The graph looks like this:
For your second question, A=P[1 +r/n]^nt is for interest compounded for periods such as annually, semiannually, quarterly, daily, etc. The formula A=Pe^rt is for interest compounded continuously.
Find the accumulated value of an investment of $10,000 at 4% compounded annually for 17yrs.
Use the first formula above, where P=$10,000, r=.04, n=1 time per year, and t= 17 years.
I get this with this formula and a calculator: A= 10000[1+.04)^17 =$19479.00496
Final answer: $19,479.00 What did you get??
