(1 point) Find a formula for the nth term in the sequence: 17,−17/8,17/27,−17/64,17/125,…

lana [24]

Given:

The sequence is:

$17,-\dfrac{17}{8},\dfrac{17}{27},-\dfrac{17}{64},\dfrac{17}{125},...$

To find:

The formula for the nth term in the given sequence.

Solution:

We have,

$17,-\dfrac{17}{8},\dfrac{17}{27},-\dfrac{17}{64},\dfrac{17}{125},...$

The given sequence can be written as

$\dfrac{17}{1^3},-\dfrac{17}{2^3},\dfrac{17}{3^3},-\dfrac{17}{4^3},\dfrac{17}{5^3},...$

The sign are alternative and the absolute value of each term can be defined by the expression $\dfrac{17}{n^3}$ , where n is a natural number.

So, the required formula is:

$a_n=(-1)^{n+1}\dfrac{17}{n^3}$

Therefore, the formula for nth term in the given sequence is $a_n=(-1)^{n+1}\dfrac{17}{n^3}$ .

Diana paints 150 fence posts and chuck paints 130 fence posts. Diana paints 10 more fence posts than chuck. How many fence posts

statuscvo [17]

Complete Question

The complete question is shown on the first uploaded image

Answer:

Step-by-step explanation:

From the question we are told that

The relationship is $\frac{150 }{d} = \frac{130}{c}$

The number of fence post painted by chuck is $l = 130$

The number of fence post painted by Diana is $k = 150$

can paint 10 fences more than chuck so let say the of fence painted in an hour by chuck is $g$

Then the number of fence post painted by Diana in one hour is

$f = g+ 10$

$\frac{150 }{ g + 10 } = \frac{130}{g}$

$130 g + 1300 = 150g$

$g = 65 \ m$

Adele works at an appliance store. She recently sold 18 appliances, 2 of which were ovens. What is the experimental probability

swat32

Answer: The experimental probability of 2/9

Step-by-step explanation:

2/18= 1/9 * 2= 2/9 so on the first try,she sold 2 out of 18 which means the experimental probability is 2/18 = 1/9 so since this is the second try, you will have to multiply 1/9 by 2 to find the next possible outcome.
