Is trigonometry challenging?

This is due to the fact that trigonometry is still regarded as a very challenging and abstract branch of mathematics in comparison to other branches. When learning trigonometry, students frequently run into mistakes, misunderstandings, and barriers. A subfield of mathematics known as trigonometry studies how angles and length ratios relate to one another. Applications of geometry to astronomical research led to the field's emergence in the Hellenistic civilization during the third century BC.

cosecx(secx−1)−cotx(1−cosx)

= 1/sinx*1(1-cosx)/sinxcosx−cosx(1−cosx)/sinx

=((1−cosx)−sinxcosx(1−cosx))/sinxcosx

=sinxcosx(1−cosx)−cos^2x(1−cosx)​

=(1−cosx)(1−cos2x)/sinxcosx

=(1−cosx)×sin2^x/sinxcosx

=tanx(1−cosx)

=tanx−tanxcosx

=tanx−sinx/cosx×cosx

=tanx−sinx

3 times the length of a field increased by 4 times the width gives 24 units. Two times the length decreased by 3 times the width is -1 unit. Find the dimensions

Answers

Answer:

width = 3

length = 4

Step-by-step explanation:

Ok so you can form a system of equations where w is the width and l is the length:

3l + 4w = 24

2l - 3w = -1

you want to eliminate one of the variables and then solve, so you can first take the top equation and multiply both sides by 2:

6l + 8w = 48

next, multiply the second equation by 3:

6l - 9w = -3

now that both include 6l, you can subtract the two equations

6l + 8w = 48

- (6l - 9w = -3)

17w = 51

divide both sides by 17

w = 3

Plug w = 3 into the equation 3l + 4w = 24:

3l + 4 * 3 = 24

3l + 12 = 24

subtract 12 from both sides

3l = 12

divide both sides by 3

l = 4

I believe the answer is an average of 4800 beats per hour.
We know that the heart beats an average of 80 beats per minute and there are 60 minutes in an hour. We can use this information and multiply 80x60 to find the average amount of heartbeats in an an hour.

The interior angles of ∆AUL (or any triangle for that matter) sum to 180°, so

∠3 + 20° + 57° = 180°

===>   ∠3 = 103°

Angles ∠3 and ∠4 occur on the same ray LP, so they are supplementary to one another. In other words,

∠3 + ∠4 = 180°

so that

∠4 = 180° - 103° = 77°

Number line graph with closed circles on 0 and 24 and shading in between.

Answers

Answer:

Number line graph with closed circle on 24 and shading to the right.

Step-by-step explanation:

First, the graph has to have a closed circle on only 24.

Since she has $61 and needs at least $85 to buy a skateboard, she needs to have at least $24 saved to buy one.

This means the last 2 answer choices are wrong, because there cannot be shading in between.

The first answer choice is also wrong because it puts a open circle, instead of a closed one, on 24.

So, the correct answer is Number line graph with closed circle on 24 and shading to the right.

Step-by-step explanation:

Relative frequency of head = [tex]\dfrac{\text{Number of times heads occur}}{\text{Total number of times coin is flipped}}[/tex]

Let x= Number of times the coin is flipped, then

[tex]0.6=\dfrac{300}{x}\\\\\Rightarrow\ x=\dfrac{300}{0.6}\\\\\Rightarrow\ x=\dfrac{3000}{6}\\\\\Rightarrow\ x=500[/tex]

Step-by-step explanation:

Computing 40% can be done a couple of ways.

  40% = 40/100 = 4/10 = 2/5

  40% of 35 = (2/5)(35) = 2(35/5) = 2(7) = 14

__

  40% = 4/10 = 2(2(1/10))

  40% of 36 = 2(2(1/10)(35)) = 2(2(3.5)) = 2(7) = 14

The amount discounted is $14.

So, our formula would be like this: P = 2*9 + 2*6.

You deposit $500 in an account that earns 6.5% annual interest compounded yearly. Write a function that represents the balance y (in dollars) after x years.

Answers

Answer:

f(x)=.65+y

Step-by-step explanation:

               .

The function for compound interest is A = 500 ( 1.065 )ˣ

What is Compound Interest?

Compound interest is interest based on the initial principle plus all prior periods' accumulated interest. The power of compound interest is the ability to generate "interest on interest." Interest can be added at any time, from continuously to daily to annually.

The formula for calculating Compound Interest is

A = P ( 1 + r/n )ⁿᵇ

where A = Final Amount

P = Principal

r = rate of interest

n = number of times interest is applied

b = number of time periods elapsed

Given data ,

Let the compound interest amount be represented as A

Now , the interest rate r = 6.5 %

The number of times the interest is applied = yearly

The principal amount P = $ 500

n = 1 ( compounded yearly )

t = x ( number of years )

So, the function that represents the balance y (in dollars) after x years is:

y ( x ) = 500 ( 1 + 0.065/1 )ˣ

On simplifying , we get

y ( x ) = 500 ( 1.065 )ˣ

Hence , the function is A = 500 ( 1.065 )ˣ

Im soooo confused Source: Henry Byroade, Assistant Secretary of State in the United States State Department, memorandum to his superior regarding British proposals concerning the overthrow of the government of Muhammad Mosaddegh, the nationalist prime minister of Iran, November 26, 1952. In August of 1953, Mosaddegh was overthrown in a coup organized by the CIA and the British intelligence agency MI6.The British Foreign Office has informed us that it is inclined to bring about a coup d'etat in Iran, replacing the Mosaddegh government by one that would be more reliable," if the United States government agreed to cooperate. You will recall the British embassy on October 8 gave us a paper that outlined the possible ways of meeting the threat that would be posed if the communist party of Iran (which is supported by the Soviet Union) took advantage of Mosaddegh's weakness to seize power. Since then, the State Department and CIA have had three meetings with British representatives. The British believe that there is virtually no chance of an oil settlement* with Mosaddegh and they have little hope that his government will be able to prevent a communist takeover. The British do not appear to have a specific candidate in mind as the leader of the suggested coup, but they believe that several of the "old guard" politicians and more moderate nationalist leaders would be good candidates.CIA believes that the project is probably feasible and that it could be handled in a way that British and American connection with it could never be proven. However, many things could go wrong. Furthermore, it must be assumed that the Iranians would charge the British with complicity in any sudden political development of this sort, with or without proof, and that this charge would be echoed by the Soviet bloc. There is also the danger of possible violent Soviet reaction, especially if the coup was not completely successful from the beginning.
