Answer:

[tex] - \frac{sec^{2}x }{2 \tan (\frac{3}{2} ) x} [/tex]

Step-by-step explanation:

use chain rule on

[tex] \frac{d}{dx} \frac{1}{ \sqrt{ \tan\: (x)} } [/tex]

Let u = tan x.

Use power rule

[tex] \frac{d}{du} {u}^{n} = nu ^{n - 1} [/tex]

[tex] - \frac{1}{2 \tan( \frac{3}{2}x ) } ( \frac{d}{dx} \tan \: (x) )[/tex]

Use Trigonometric Differentiation: the derivative of tan x is sec² x.

[tex] - \frac{ \sec^{2} x}{2 \tan( \frac{3}{2} ) x} [/tex]

Answer:

Step-by-step explanation:

Answer:

A. 2

Step-by-step explanation:

From the diagram, it is indicated;

AD = DB = 3t,

AC = 7t + 6

CE = EB = 4t

Perimeter = 48 units

Perimeter = AD + DB + AC + CE + EB

Plug in the values

48 = 3t + 3t + 7t + 6 + 4t + 4t

Add like terms

48 = 21x + 6

48 - 6 = 21x + 6 - 6

42 = 21x

42/21 = 21x/21

2 = x

x = 2

Answer:

The answer is D

Step-by-step explanation:

y=kx

9=k

Plug it in they are all true.

The table represents a direct proportion between the number of tickets sold and the total cost will be D.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The slope of the line is given as,

m = (y₂ - y₁) / (x₂ - x₁)

For the linear relationship, the slope will remain constant.

Let's check all the options, then we have

A. The slope is given as,

m = (2 - 0) / (1 - 0) = (4 - 2) / (3 - 1)

m = 2 ≠ 1

B. The slope is given as,

m = (4 - 0) / (2 - 0) = (6 - 4) / (4 - 2)

m = 2 ≠ 1

C. The slope is given as,

m = (7 - 5) / (2 - 1) = (9 - 7) / (3 - 2) = (11 - 9) / (4 - 3)

m = 2 = 2 = 2

The y-intercept is 3.

D. The slope is given as,

m = (18 - 9) / (2 - 1) = (27 - 18) / (3 - 2) = (36 - 27) / (4 - 3)

m = 9 = 9 = 9

The y-intercept is zero.

The table addresses an immediate extent between the number of tickets sold and the all-out cost will be D.

Answer:

Answer:

12247

Step-by-step explanation:

Accounts receivables A/R are the amounts that will be collected from customers to whom goods are sold on credit.

Now, since there are 12,247 customers to whom the credit has been extended to, there will be equal number of 12,247 accounts receivable in their books and a single GL (General ledger) will be there representing and showing the total amount due from these 12,247 customers.

that is, the company will have to make 12,247 accounts receivable accounts, each having the names of the respective customers.

Answer:

[tex]3v^{2}[/tex]

Answer:

m<N = 130°

m<K = 50°

x = 28

Step-by-step explanation:

angle N and angle K are supplementary so the sum of their measures is 180°

4x + 18 + 2x - 6 = 180 add like terms

6x + 12 = 180 subtract 12 from both sides

6x = 168 divide both sides by 6

x = 28 to calculate the measurements of angle N and K replace x with 28

N = 4x + 28 so 4 × 28 + 18 = 130°

N = 2x - 6 and 2×28 - 6 = 50°

9514 1404 393

Answer:

Step-by-step explanation:

The Pythagorean theorem tells you the square on the hypotenuse is equal to the sum of the squares on the other two sides. (This is the version you use for problem 2.)

This also means the square on one side is the difference between the square on the hypotenuse and the square on the other side. (Use this version for problems 1 and 3.)

1. ? = 200 in² -75 in² = 125 in²

2. ? = 576 km² + 100 km² = 676 km²

3. ? = 36 square units - 16 square units = 20 square units

The answer to your question is :

Explanatory variable <--------> The first freezer

Response variable <---> The time required for the water to turn into ice in each freezer

control group <------------------> The second freezer

An Explanatory variable in an experiment is the variable that has been changed/manipulated by the researcher for the purpose of the experiment/research it is an independent variable ( as seen in first freezer )

A Response variable is the outcome of an experiment that serves as an evidence of the effect of the explanatory variable. it is a dependent variable

The control group is the made up of the refrigerators whom are not cooled using the new formula of refrigerant ( i.e. the second freezer )

hence the explanatory variable is the first freezer, the response variable is the time required for the water to turn into ice in each freezer, while the control group is the second freezer.

Answer:

Good luck to whoever figures out the last one.

Step-by-step explanation:

Let's say we had a sample of 100 people. We'll split them into two equal groups of 50 each. The two groups will be the treatment and control groups. The treatment group, aka experimental group, is where the actual drug is given. The control group is where the fake drug is given. People in the control group must not know the pill is fake. For more info, check out the placebo effect. In short, this is when a person takes a fake pill and thinks they get better, and that positive mentality helps them actually get better.  

If both the treatment and control groups improve (on average) together, then that means the fake pill is just as good as the real thing. Consequently, it means the real pill isn't effective at all. If on the other hand the experimental group does better overall compared to the control group, then we can see that the real pill is doing what it's intended to do. Of course, there are a lot of complicated factors involved, as there is with anything dealing with medicine. I haven't mentioned anything about side effects or things of that nature. In this simplified viewpoint of the world, we're only considering the one factor of whether or not the drug clears up the psoriasis on the skin.

To make things fair, it's best to randomly generate numbers so that you randomly assign people into each group. That way you have representative samples. Also, when drawing the sample of 100 people, make sure that's as random as possible to help represent the population as best as possible. The fact that the people in the control group not knowing that they are taking the fake pill means we have a single blind experiment. A double blind experiment is when even the researchers are not sure who is taking the real pill vs the fake pill. Double blind experiments are encouraged to prevent the researcher's bias from affecting the results.

To keep participants from knowing whether or not they are in the control group, the common solution is to provide a sugar pill. The pill will not cause any side effects and will not cause any improvements to health. It's simply sugar. To the participant, it seems like the real thing since they can't taste the difference or detect anything seems different.

Answer:

Randomly select a sample of people with psoriasis. Randomly assign them to one of two groups. Give one group the​ treatment, and withhold it from the other group. Give both groups similar looking​ pills, so neither knows which group they are in.

Step-by-step explanation:

When multiplying fractions, we can multiply them straight across.

[tex]\frac{3}{8}[/tex]×[tex]\frac{5}{6}[/tex]

[tex]\frac{15}{48}[/tex]

15 and 48 have a common factor, which is 3, so we can divide the numerator and denominator by 3 to simplify.
