Cot x sin x = cos x?

Mathematics
1 answer:
NeTakaya3 years ago
5 0

Answer:

cot(x) sin(x) = cos(x)

OK so what you are gonna do is first manipulate the left side of the equation

cot(x) sin(x)

So, you are gonna express with sin, cos

cos(x)/ sin(x) sin(x)

Then you will simplify cos(x)/ sin(x) sin(x)  and get:

= cos (x)

So the equation cot(x) sin(x) = cos(x)  is TRUE

(I hope this helps you! If it does please consider giving me the brainliest! It would really help me out and I would really appreciate it)

MAXImum [283]

Answer:

For 1) you must do that yourself from least to greatest.

2) most snow was 3 and 3/4

3) least snow was 1 and 2/4

4) it snowed 3 and 1/4 3 days long.

5) it could have been 4 and 2/4 with another 1 and 2/4 since that makes three or maybe just 4 with 1 since that also makes three there are a lot of possibilities considering it only has to be subtracted and equal three.

Step-by-step explanation:

Hope this helped.

A brainliest is always appreciated.

How to get answer:

Expand -2\left(x+13\right)+9x:\quad 7x-26\\Expand -2\left(x+13\right):\quad -2x-26\\\\=-2x-26+9x\\Simplify -2x-26+9x:\quad 7x-26\\7x-26=4\\\mathrm{Add\:}26\mathrm{\:to\:both\:sides}\\7x-26+26=4+26\\\mathrm{Simplify}\\7x=30\\\\\mathrm{Divide\:both\:sides\:by\:}7\\\frac{7x}{7}=\frac{30}{7}\\Simplify\\x=\frac{30}{7}

The sum of the measures of a pair of alternate angles of two parallel lines is 210°. What are the measures of these two angles?
aniked [119]
The answer is 105 and 105 because they did not tell you that one had more than the other, so it's equal. Plus, it could not be 210 or over or 0 or less. It was spilt up equally between both alternate angles, and the lines are parallel, so the angles are equal. So just do 210/2 and get what one of the angles would be. Great question!

A researcher selects all of the possible samples with n = 8 scores from a population and computes the mean, dividing by n, for e
Nadusha1986 [10]

Answer:

By the Central Limit Theorem, the average value for all of the sample means is 14.

Step-by-step explanation:

We use the central limit theorem to solve this question.

The Central Limit Theorem estabilishes that, for a random variable X, with mean \mu and standard deviation \sigma, the sample means of size n can be approximated to a normal distribution with mean \mu and standard deviation, which is also called standard error s = \frac{\sigma}{\sqrt{n}}

If the population mean is μ = 14, then what is the average value for all of the sample means?

By the Central Limit Theorem, the average value for all of the sample means is 14.
