Answer:

[tex]\displaystyle \sin\Big(\frac{x}{2}\Big) = \frac{7\sqrt{58} }{ 58 }[/tex]

[tex]\displaystyle \cos\Big(\frac{x}{2}\Big)=-\frac{3 \sqrt{58}}{58}[/tex]

[tex]\displaystyle \tan\Big(\frac{x}{2}\Big)=-\frac{7}{3}[/tex]

Step-by-step explanation:

We are given that:

[tex]\displaystyle \sin(x)=-\frac{21}{29}[/tex]

Where x is in QIII.

First, recall that sine is the ratio of the opposite side to the hypotenuse. Therefore, the adjacent side is:

[tex]a=\sqrt{29^2-21^2}=20[/tex]

So, with respect to x, the opposite side is 21, the adjacent side is 20, and the hypotenuse is 29.

Since x is in QIII, sine is negative, cosine is negative, and tangent is also negative.

And if x is in QIII, this means that:

[tex]180<x<270[/tex]

So:

[tex]\displaystyle 90 < \frac{x}{2} < 135[/tex]

Thus, x/2 will be in QII, where sine is positive, cosine is negative, and tangent is negative.

1)

Recall that:

[tex]\displaystyle \sin\Big(\frac{x}{2}\Big)=\pm\sqrt{\frac{1 - \cos(x)}{2}}[/tex]

Since x/2 is in QII, this will be positive.

Using the above information, cos(x) is -20/29. Therefore:

[tex]\displaystyle \sin\Big(\frac{x}{2}\Big)=\sqrt{\frac{1 + 20/29}{2}[/tex]

Simplify:

[tex]\displaystyle \sin\Big(\frac{x}{2}\Big)=\sqrt{\frac{49/29}{2}}=\sqrt{\frac{49}{58}}=\frac{7}{\sqrt{58}}=\frac{7\sqrt{58}}{58}[/tex]

2)

Likewise:

[tex]\displaystyle \cos \Big( \frac{x}{2} \Big) =\pm \sqrt{ \frac{1+\cos(x)}{2} }[/tex]

Since x/2 is in QII, this will be negative.

Using the above information, cos(x) is -20/29. Therefore:

[tex]\displaystyle \cos \Big( \frac{x}{2} \Big) =-\sqrt{ \frac{1- 20/29}{2} }[/tex]

Simplify:

[tex]\displaystyle \cos\Big(\frac{x}{2}\Big)=-\sqrt{\frac{9/29}{2}}=-\sqrt{\frac{9}{58}}=-\frac{3}{\sqrt{58}}=-\frac{3\sqrt{58}}{58}[/tex]

3)

Finally:

[tex]\displaystyle \tan\Big(\frac{x}{2}\Big) = \frac{\sin(x/2)}{\cos(x/2)}[/tex]

Therefore:

[tex]\displaystyle \tan\Big(\frac{x}{2}\Big)=\frac{7\sqrt{58}/58}{-3\sqrt{58}/58}=-\frac{7}{3}[/tex]

Answer:

formula is speed equals distance/ time.

now, speed above is 85km/h and distance is 42km.

time therefore is 42/85 which is 0.494h

now, 0.494h× 60 minutes is 29.64minutes(which is your answer in minutes)

now,29.64minutes × 60secs is 1778.82 seconds to the nearest seconds is 1779 seconds( which is your answer in seconds)

137 because they are 180 angles so you subtract 180-43=137.

Answer:

so in this figure the 43°=y°(by vertical opposite angle)

y°+z°=180°(by linear pair)

43°+z°=180°

z=180°-43°

z=137°

Slope is change in y over the change in x.

Slope = (-7 - 2) / (-1 -2)

Slope = -9/-3

Slope = 3

Answer:

the set of all possible input values for a function is called the domain of the function, and the set of all output values for a function is called the range. ... The y variable is the dependent variable and represents the corresponding output value f (x) in the rang

Answer: 5940

Step-by-step explanation: I don't know if it's for sure right but here

First I knew 10,800 was 100% and I wanted to find 2.5%

So I did:

10,800 divided by 100 and I got 108 = 1%

Than you want to do

108 x 2.5 = 270 ( 2.5% )

After that you wanted to find out how much years apart so

2021 - 2003 = 18

Then

18 x 270 = 4,860

Last of all you have to do

10,800 - 4,860 = 5940

Answer:

A and E

Step-by-step explanation:

If you add all the perimeters and the half circles, it would make 40 + 20π. And you can get this in two ways. A and E

Answer:

The correct answer is A and E.

Step-by-step explanation:

The perimeter of this shape is 10 + 10 + [tex]\frac{20\pi }{2}[/tex] + 10 + 10 + [tex]\frac{20\pi }{2}[/tex] = 10 + 10 + [tex]10\pi[/tex] + 10 + 10 + [tex]10\pi[/tex] = 40 + [tex]20\pi[/tex].

Answer:

(3,5)

Step-by-step explanation:

If you imagine a grid in your head, moving 3 units to the right is the same as 3 on the x axis, and 5 units above the x axis is the same as 5 on the y axis. X goes before y in an ordered pair, so the answer would be (3,5). Hope this helps!!

Given:

A city's population has increased 40% in the last 5 years and is now 53,782 people.

To find:

The population 5 years ago.

Solution:

Let x be the population 5 years ago.

A city's population has increased 40% in the last 5 years.

So, present population is

[tex]x+x\times \dfrac{40}{100}=x+0.4x=1.4x[/tex]

It is given that the present population is 53782.

[tex]1.4x=53782[/tex]

[tex]x=\dfrac{53782}{1.4}[/tex]

[tex]x=38415.7142857[/tex]

[tex]x\approx 38416[/tex]

Therefore, the population 5 years ago was about 38416.
