Answer:
2 sin A / cos 3A + 2 sin 3A / cos 9A + 2 sin 9A / cos 27A = tan 27A - tan A
2 sin A/cos 3A
Multiply with cos A to Numerator and denominator
= 2 sin A cos A/cos 3A cos A
Formula (sin 2A = 2 sin A cos A)
= sin 2A / cos 3A cos A
Formula [ (sin a-b) / cos a cos b = tan a - tan b ]
So,
= sin 3A - A / cos 3A cos A
= tan 3A - tan A----> Equation 1
Apply same procedure we get
2 sin3A / cos 9A = tan 9A - tan 3A---> Equation 2
2 sin 9A / cos 27A = tan 27A - tan 9A----> Equation 3
Add Equation 1,2 and 3
tan 3A - tan A + tan 9A - tan 3A + tan 27A - tan 9A = tan 27A - tan A
2 sin A / cos 3A + 2 sin 3A / cos 9A + 2 sin 9A / cos 27A = tan 27A - tan A

If 2^x=3^y=12^z, show that 1÷z=1÷y+2÷x.....
Answer:
Proof of [tex]\dfrac{1}{z}}=\dfrac{1}{y}+\dfrac{2}{x}[/tex] is shown below.
Explanation:
The given equation is
[tex]2^x=3^y=12^z[/tex]
To prove : [tex]\dfrac{1}{z}=\dfrac{1}{y}+\dfrac{2}{x}[/tex]
Proof : Let as assume,
[tex]2^x=3^y=12^z=k[/tex]
[tex]2^x=k\Rightarrow 2=k^{\frac{1}{x}}[/tex] ...(1)
[tex]3^y=k\Rightarrow 3=k^{\frac{1}{y}}[/tex] ...(2)
[tex]12^z=k\Rightarrow 12=k^{\frac{1}{z}}[/tex] ...(3)
We know that
[tex]12=2\times 2\times 3[/tex]
[tex]12=(2)^2\times 3[/tex]
Using (1), (2) and (3), we get
[tex]k^{\frac{1}{z}}=(k^{\frac{1}{x}})^2\times k^{\frac{1}{y}}[/tex]
[tex]k^{\frac{1}{z}}=k^{\frac{2}{x}}\times k^{\frac{1}{y}}[/tex]
[tex]k^{\frac{1}{z}}=k^{\frac{2}{x}+\frac{1}{y}}[/tex]
On comparing both sides, we get
[tex]\dfrac{1}{z}}=\dfrac{2}{x}+\dfrac{1}{y}[/tex]
[tex]\dfrac{1}{z}}=\dfrac{1}{y}+\dfrac{2}{x}[/tex]
Hence proved.
According to Weber’s law, whether you can detect a change in a stimulus depends on how much the stimulus changes and the ___
Answer:
This question lacks options, options are:
A. Perception of depth.
B. Strength of the original stimulus.
C. Law of visual organization.
D. Law of proximity
The correct answer is B.
Explanation:
Perception can be defined as the set of processes and activities related to the stimulation that reaches the senses, through which we obtain information regarding our habitat, the actions we carry out in it and our own internal states. Weber's law states that the increase in the intensity of the stimulus necessary to provoke a change in sensation is proportional to the intensity of the initial stimulus, that is, the stronger the initial stimulus is, the greater the additional intensity required for the second stimulus to be perceived as different.

It yield to the driver approaching on the right. The correct option is D.
Thus, At a four-way stop, the driver in the opposing lane should have the right of way while making a left turn. Give the driver enough time to cross the crossing before you proceed.
Give the driver on the interstate highway the right of way if you are on the acceleration ramp or the entrance. You must give them the right of way because these drivers are almost certainly travelling at a fast rate of speed.
At a four-way stop with stop signs in place, the driver on your right has the right of way. At the crosswalks, those who are biking, walking, or crossing at a four-way intersection always have the right of way.
Thus, It yield to the driver approaching on the right. The correct option is D.

Answer:
To be emancipated at such a young age, the only viable option is to permanently leave your home and cut off relations to the parents, except in cases of child abuse. Check out the official nycourts"dot"gov website to see all legal emancipations for a child under 21.
To live on your own, you need to find income so you can pay for necessities such as food and shelter. Everything else is secondary. Without these two things, you can expect to be homeless or worse.
It'll be impossible to move to Los Angeles with no money, unless you can trade a service or something similar to finance your travels from New York to California. (Note, expenses in Los Angeles are in the top, if not the top in the USA).

How does the location of muscle in an animal affect your choice of cookery method for the preparation of a dish? How does this affect economic aspects in commercial cookery?
Answer:
The location of muscle in an animal lay affect your choice of cookery method because when we have a strong muscle we will need more cooking time, such as boiling or a combination of them. In commercial cookery it has to be taken into account because of the energy (gas or electricity) used and the time needed to be done. In business this has to be analyzed in order to say which is the most profitable way to cook.
Explanation:
The tenderness of meat is defined and affected by muscles and their connective tissue. Depending on the tenderness of meat, we should select different temperatures of cooking and different methods. Some other factors we should take into account can be: fat, collagen and cooking loss.
Time of cooking also will affect final juiciness of meat. Casserole is an example of a slow cook method for strong muscles and it could take two hours for a meat to be ready. When it comes to grill and roast, they can be used for less strong meat.

the nurse has provided teaching to a patient who has diverticular disease but is not expericing an acute episode at this time. which statement by the patient reflects an adequate understanding of the tr=eaching?
Answer: The options are missing from the question,the options are;
"I will eat a diet that is low in fiber"
"I will avoid eating nuts and seeds"
"I will decrease my intake of fats and red meats"
"I will continue to work out by lifting weights"
The correct answer to the question is C
"I WILL DECREASE MY INTAKE IF FATS AND RED MEATS"
Explanation: Diverticular disease is the disease of the intestine that is characterised by formation of pouches,pockets or sac like structures in the intestine causing pain and sometimes inflammation.these small pouches are known as diverticula.
Individuals are encouraged to take meals that are high in fiber,fibers from vegetables and fruits and also to reduce their intake of red meat and fats as well as maintain a high level of physical activity inorder to decrease their risk of having diverticular disease.
It is yet to be proven that seeds and nuts can prevent diverticular disease but one can take a high fiber content meals once he or she presents with diverticular disease.
In diverticular disease,the goal is to apply less pressure on the abdomen inorder to avoid pain, an attack on the intestine or bursting of the pouches.
A patient with diverticular disease therefore needs to do activities and that will put little or no pressure on the abdomen, activities like vomitting,bending, straining at stool,lifting heavy objects and wearing tight) restrictive clothing can cause intraabdominal pressure and thus precipitating an attack on the already diseased intestine.
