We want the final coordinate of K to become (-3,1). If you reflect across the y-axis, you transform

$(x,y)\mapsto(-x,y)$

So, we need to move K to (3,1), and then reflect it across the y-axis. Since K starts at (-1,4), we have to move it 4 units to the right and 3 units down.

37th term; a1 = 2.3; d = -2.3

Sindrei [870]

Answer:

37th term of given arithmetic sequence $a_1$ = 2.3; d = -2.3 is -80.5.

Solution:

Given that

Need to determine 37th term, when $a_1$ = 2.3, d = -2.3

Means first term of arithmetic sequence = $a_1$ = 2.3 and common difference d = -2.3

Formula for nth term of arithmetic sequence is

$\mathrm{a}_{\mathrm{n}}=\mathrm{a}_{1}+(\mathrm{n}-1) \mathrm{d}$ --- equation 1

$\text { In our case } a_{1}=2.3, d=-2.3$

We need to determine 37th term so n = 37.

On substituting given values in equation (1) we get

$\mathrm{a}_{37}=\mathrm{a}_{1}+(37-1) \mathrm{d}$

$\begin{array}{l}{\Rightarrow a_{37}=2.3+(37-1)(-2.3)} \\\\ {\Rightarrow a_{37}=2.3(1-36)=2.3 \times 35=-80.5}\end{array}$

Hence 37th term of given arithmetic sequence is -80.5

Qualitative researchers use qualitative analysis computer programs to a. validate the findings. b. transcribe interview recordin

Ksivusya [100]

Qualitative researchers use qualitative analysis computer programs to assign labels or codes to data.

What does qualitative research analysis entail?

To better comprehend ideas, opinions, or experiences, qualitative research entails gathering and evaluating non-numerical data (such as text, video, or audio).
It can be utilized to uncover intricate details about a situation or to spark fresh study concepts.

The following five categories can be used to categorize qualitative data analysis-

content evaluation
To classify,
summarize, and tabulate the data,
verbal or behavioral data must be categorized.
Analyzing stories.
discourse examination.
Framework examination. logical theory.

Slope of the line that passes through (-3, -2) and (-3, 6), please!

Serjik [45]

Answer:

slope is undefined

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 3, - 2) and (x₂, y₂ ) = (- 3, 6)

m = $\frac{6+2}{-3+3}$ = $\frac{8}{0}$

Since division by zero is undefined then the slope is undefined

Find maclaurin series

Mumz [18]

Recall the Maclaurin expansion for cos(x), valid for all real x :

$\displaystyle \cos(x) = \sum_{n=0}^\infty (-1)^n \frac{x^{2n}}{(2n)!}$

Then replacing x with √5 x (I'm assuming you mean √5 times x, and not √(5x)) gives

$\displaystyle \cos\left(\sqrt 5\,x\right) = \sum_{n=0}^\infty (-1)^n \frac{\left(\sqrt5\,x\right)^{2n}}{(2n)!} = \sum_{n=0}^\infty (-5)^n \frac{x^{2n}}{(2n)!}$

The first 3 terms of the series are

$\cos\left(\sqrt5\,x\right) \approx 1 - \dfrac{5x^2}2 + \dfrac{25x^4}{24}$

and the general n-th term is as shown in the series.

In case you did mean cos(√(5x)), we would instead end up with

$\displaystyle \cos\left(\sqrt{5x}\right) = \sum_{n=0}^\infty (-1)^n \frac{\left(\sqrt{5x}\right)^{2n}}{(2n)!} = \sum_{n=0}^\infty (-5)^n \frac{x^n}{(2n)!}$

which amounts to replacing the x with √x in the expansion of cos(√5 x) :

$\cos\left(\sqrt{5x}\right) \approx 1 - \dfrac{5x}2 + \dfrac{25x^2}{24}$
