Find the 9th term in a geometric sequence whose common ration is 1/3 and first term is 6
sasho [114]

Answer:

Therefore 9th term of the geometric sequence is \frac{2}{2187}

Step-by-step explanation:

Given first term(a) = 6

and common ratio = \frac{1}{3}

T_n= ar^{n-1}

\therefore T_9=ar^{9-1}

\Leftrightarrow  T_9=a r^8

\Leftrightarrow  T_9=6\times ( \frac{1}{3}) ^8

\Leftrightarrow  T_9=\frac{2}{2187}

Therefore 9th term of the geometric sequence is \frac{2}{2187}

Write the polynomial equation for -1/5,-1/2,-4​
ycow [4]

Answer:

(5x+1)(2x+1)(x+4)

Step-by-step explanation:

The factored from of a polynomial can be found from the zeros or x-intercepts of the graph.

The x-intercepts here are x= -1/5, x=-1/2 and x= -4. You can find the factors by finding the expression which solves for each value.

Since x = -1/5 then the factor is 5x+1.

Since x = -1/2 then the factor is 2x+1.

Since x = -4 then the factor is x+4.

So the factored form is (5x+1)(2x+1)(x+4).
