Answer:

just took the test answer is C

Step-by-step explanation:

Answer:

zero

Step-by-step explanation:

the slope of a function m: y2-y1/x2-x1

m=-3-(-3)/5-(-5)

m=0/10=0

The slope of the line drawn passing through (- 5, - 3) and (5, - 3) is zero, so option C is correct.

An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.

Given:

straight line drawn passing through (- 5, - 3) and (5, - 3)

Calculate the slope of the line as shown below,

[tex]m = y_2 - y_1 / x_2 - x_1[/tex]

m = slope

m = -3 - (-3) / 5 - (-5)

m = 0 / 10

m = 0

Therefore, the slope of the line drawn passing through (- 5, - 3) and (5, - 3) is zero.

where x is nonzero

=======================================================

Explanation:

We'll use two rules here

------------------------------

The portion [ x^(a-b) ]^(a+b) would turn into x^[ (a-b)(a+b) ] after using the first rule shown above. That turns into x^(a^2 - b^2) after using the difference of squares rule.

Similarly, the second portion turns into x^(b^2-c^2) and the third part becomes x^(c^2-a^2)

-------------------------------

After applying rule 1 to each of the three pieces, we will have 3 bases of x with the exponents of (a^2-b^2),  (b^2-c^2) and (c^2-a^2)

Add up those exponents (using rule 2 above) and we get

(a^2-b^2)+(b^2-c^2)+(c^2-a^2)

a^2-b^2+b^2-c^2+c^2-a^2

(a^2-a^2) + (-b^2+b^2) + (-c^2+c^2)

0a^2 + 0b^2 + 0c^2

0+0+0

0

All three exponents add to 0. As long as x is nonzero, then x^0 = 1

Step-by-step explanation:

Answer:

The following characteristics of experiments are not also characteristics of surveys:

- The first one is B. The study compares two or more treatments (possibly including "no treatment").

- The other one is D. The study involves one or more treatment groups and a control group.

Step-by-step explanation:

surveys are tested with one group

The two options are B) and C) because they are characteristics of science.

The main characteristics of surveys are as follows:

1.measurable survey objectives.

2.sound research design.

3.effective survey question design.

4.sound sampling strategy, when needed.

5.effective survey response strategy.

6.meaningful data summary.

7.effective data display and reporting.

Answer:

We need to evaluate [tex]\frac{j}{4}[/tex] for j = 12.

First, we need to replace j by 12 on [tex]\frac{j}{4}[/tex], so we get [tex]\frac{12}{4}[/tex] and now, we only need to divide:

Answer:

[tex]x\approx12.1940[/tex]

Step-by-step explanation:

So we want to find the value of x.

To do so, we can use the standard trigonometric ratios.

Focus on Angle B. The opposite side is 8, and the hypotenuse is x. Therefore, we can use the sine function.

Recall that sine is:

[tex]\sin(x)=opp/hyp[/tex]

Substitute 41 for x, 8 for the opposite, and x for the hypotenuse:

[tex]\frac{\sin(41)}{1}=\frac{8}{x}[/tex]

Cross multiply:

[tex]8=x\sin(41)[/tex]

Divide both sides by sin(41):

[tex]x=8/\sin(41)[/tex]

Use a calculator:

[tex]x\approx12.1940[/tex]

Answer:

2⁸ > 2.38 × 10² > 6³ > 2.16 × 10¹ > [tex]\sqrt{300}[/tex], 300%

Step-by-step explanation:

Given numbers are,

2.38 × 10², √300, 2⁸, 300%, 6³, 2.16 × 10¹

We have to arrange these numbers in the decreasing order(from greatest to least)

2.38 × 10² = 2.38 × 100 = 238

√300 = 10√3 ≈ 17.32

2⁸ = 256

300% = [tex]\frac{300}{100}[/tex] = 3

6³ = 216

2.16 × 10¹ = 21.6

Therefore, decreasing order (from the greatest to least) will be,

256 > 238 > 216 > 21.6 > 17.32 > 3

2⁸ > 2.38 × 10² > 6³ > 2.16 × 10¹ > [tex]\sqrt{300}[/tex], 300%
