Write the terms a 1a1, a 2a2, a 3a3, and a 4a4 of the following sequence. If the sequence appears to converge, make a conjec

Arturiano [62]

Answer:

Step-by-step explanation:

WE are given that $a_n = \frac{(-1)^{n+1}}{5n-4}$ . Then, to now the first for terms, we must replace n by 1,2,3,4 respectively. Then

$a_1 = \frac{(-1)^2}{5(1)-4} = \frac{1}{1}= 1$

$a_2 = \frac{(-1)^3}{5(2)-4} = \frac{-1}{6}$

$a_3 = \frac{(-1)^4}{5(3)-4} = \frac{1}{11}= 1$

$a_4 = \frac{(-1)^5}{5(4)-4} = \frac{-1}{16}= 1$

Note that as n increase, $a_n$ gets closer to 0. So, the limit of this sequence is 0.

HELP!!! Does the graph represent a function and if so, why? No, some of the ordered pairs in this list have the same second elem

vlabodo [156]

Answer:

No, some of the ordered pair in this graph have the same first element.

Step-by-step explanation:

The relation of a function is that it expresses a dependence of one element on another. There is a one to one relation, which means that one point can not be used more then once.

Some ordered pairs in this graph have the same first element and are used more then once. So this graph can not represent a function.
