Can anyone help me about question 2
madreJ [45]

Answer:

  3(4/3)^2543

Step-by-step explanation:

Using logarithms base 2, we have ...

  (a_n)^{\log{a_n}}=(a_{n+1})^{\log{a_{n-1}}}\\\\(\log{a_n})(\log{a_n}) = (\log{a_{n-1}})(\log{a_{n+1}}) \\\\ \dfrac{\log{a_{n+1}}}{\log{a_{n}}}=\dfrac{\log{a_n}}{\log{a_{n-1}}}=\dots\dfrac{\log_2{16}}{\log_2{8}}=\dfrac{4}{3}

That is, the ratio of each term to the previous is a constant equal to 4/3. This is the definition of a geometric sequence. This sequence has first term 3 and common ratio 4/3, so the general term is ...

  \log_2 a_n=3\left(\dfrac{4}{3}\right)^{n-1}

and the 2544th term is ...

  \boxed{\log_2{a_{2544}}=3\left(\dfrac{4}{3}\right)^{2543}}

Find all the zeros of the function y=-7x+8
alexdok [17]

The zero of the function is for x = 0. Put the value of x to the equation

y = -7x + 8:

-7x + 8 = 0        <em>subtract 8 from both sides</em>

-7x =-8       <em>divide both sides by (-7)</em>

\boxed{x=\dfrac{8}{7}}

 -The variables cant be as radicals.
 
 Therefore:
 
 a) It is a polynomial (The variable is under a radical)
 b) It is not a polynomial.
 c) It is a polynomial.
 d) It is not a polynomial. (It has a variable in the denominator).
 e) It is a polynomial.
 f) It is not a polynomial. <span> (It has a </span><span>variable in the denominator).</span>
