Hi i need help in math pls i am really bad plssssssss
zvonat [6]

Answer:

The answer is  a= \frac{8x^2+11x+1}{2}

Step-by-step explanation:

Combine like terms and we get,

24x^2+83x+3=6ax

\frac{24x^2+33x+3}{6x} =a             divide both sides of the equation by ax, and simplify further,

\frac{x(8x^2+11x+1)}{2}                          notice that we can reduce the 24 over 6 1/2,

\frac{8x^2+11x+1}{2} =a                 distribute and simplify further

And a=\frac{8x^2+11x+1}{2}

a man invests a total of 5000 in a bank account that yields 5% interest compound monthly. how much will it be worth after 6 year
kaheart [24]

Answer:

  6745.09

Step-by-step explanation:

If we assume the nominal annual interest rate is 5%, then the future value after 6 years is ...

  FV = P(1 +r/12)^(12·t)

for P = 5000, r = .05, t = 6.

Doing the arithmetic, we get ...

  FV = 5000(1 +.05/12)^(12·6) ≈ 6745.09

After 6 years, the bank account will be worth 6745.09.

_____

We made a comment about the interest rate, because the annual <em>yield</em> is about 5.116%. If the <em>annual yield</em> is actually 5%, then the account value is lower: $6700.48. (Monthly compounding is irrelevant in that case, because it is already figured into the yield.)

Usually, the wording would be that the account <em>earns</em> 5% interest compounded monthly.
