What is the explicit formula of a1=-3,d=2

Mathematics
1 answer:
AVprozaik [17]3 years ago
7 0

Answer:

The explicit formula for the given expression is 2 n - 3

Step-by-step explanation:

Here, the first term of sequence  =  -1

The common difference  = 2

In a ARITHMETIC PROGRESSION:

The nth term of a sequence is given as

a(n) =  a + (n-1) d

⇒ Here, a(n)  = -1 + (n-1)(2)

                      = -1 + 2n -2

                       = 2n - 3

or,  a(n)  =  2n - 3

Hence, the explicit formula for the given expression is 2n - 3.

Which line is the line of reflection?<br><br>A. a<br>B. b<br>C. c<br>D. d
Leto [7]
The line of reflection is b

You can see it much easier if take away all the clutter. Redraw the diagram and take way a d and especially c.

You should be left with only line b and the two triangles. You can see it much easier if you do that. Then just look at the parallel lines of the triangles. They are right across from each other.

Find a power series representation for the function. (Give your power series representation centered at x = 0.) f(x) = x/6x^2 +
timama [110]

Looks like your function is

f(x)=\dfrac x{6x^2+1}

Rewrite it as

f(x)=\dfrac x{1-(-6x^2)}

Recall that for |x|, we have

\dfrac1{1-x}=\displaystyle\sum_{n=0}^\infty x^n

If we replace x with -6x^2, we get

f(x)=\displaystyle x\sum_{n=0}^\infty\frac(-6x^2)^n=\sum_{n=0}^\infty (-6)^n x^{2n+1}

By the ratio test, the series converges if

\displaystyle\lim_{n\to\infty}\left|\frac{(-6)^{n+1} x^{2(n+1)+1}}{(-6)^n x^{2n+1}}\right|=6|x^2|\lim_{n\to\infty}1=6|x|^2

Solving for x gives the interval of convergence,

|x|^2

We can confirm that the interval is open by checking for convergence at the endpoints; we'd find that the resulting series diverge.
