Find the limit of the sequence described by the general expression 5n+ (-1) n /n^2

Mathematics
1 answer:
elena-s [515]2 years ago
5 0

Answer:

b. 0

Step-by-step explanation:

The expression can be rewritten as:

A_{n} = \frac{5\cdot n}{n^{2}} + \frac{(-1)^{n}}{n^{2}}

As n becomes greater and begins diverging to infinity, each component of the sum converges to zero. Then, the limit of the sequence is zero.

Write the equation of a line through points (5, 5) and (1, 0) in point-slope form
klasskru [66]

Answer:

y=(5/4)x-5/4

Step-by-step explanation:

First we need to find the slope:

\frac{y_{2}-y_{1} }{x_{2}-x_{1} }

=\frac{5-0}{5-1}

=5/4

The SLops is 5/4

point-slope forum is

y=(5/4)x-5/4

F(x)=2x+1 and g(x)=x^2-7, find (f g) (x)
hodyreva [135]

The answer is (f o g)(x) = 2x^2 - 13

In order to find a composite function, you take the first letter (in this case f) and use that equation. You then remove the variable and put in the second letter (g).

f(x) = 2x + 1 ----> Remove variable.

f(x) = 2(      ) + 1 ----> Insert g(x)

(f o g)(x) = 2(x^2 - 7) + 1 ----> Distribute

(f o g)(x) = 2x^2 - 14 + 1 ----> Simplify

(f o g)(x) = 2x^2 - 13
