Answer:

Step-by-step explanation:

Here it is given that ,l ines PV , QW and RX are parallel .That is ,

[tex]\longrightarrow PV \ || \ QW \ || RX [/tex]

And we would like to find out the value of ,

[tex]\longrightarrow m\angle STW \ \& \ \angle TSV [/tex]

As we know that when a transversal intersects two parallel lines then ,

Here ,

[tex]\angle STW [/tex] and [tex]\angle TUX [/tex] are corresponding angles .So they must be equal.

[tex]\longrightarrow x = 2y \dots (i)[/tex]

Again here [tex]\angle VST[/tex] and [tex]\angle STW[/tex] are co- interior angles. So ,

[tex]\longrightarrow x + (x +5y) = 180^o \dots (ii) [/tex]

Substitute the value from equation (i) into (ii) ,

[tex]\longrightarrow 2y + 2y +5y =180^o \\[/tex]

[tex]\longrightarrow 9y = 180^o\\[/tex]

[tex]\longrightarrow y =\dfrac{180^o}{9}\\[/tex]

[tex]\longrightarrow y = 20^o [/tex]

[tex]\rule{200}4[/tex]

Therefore , we may find out the required angles as ,

[tex]\longrightarrow m\angle STW = x \\ [/tex]

[tex]\longrightarrow m\angle STW = 2y\\ [/tex]

[tex]\longrightarrow m\angle STW = 2(20^o)\\ [/tex]

[tex]\longrightarrow \underline{\underline{m\angle STW = 40^o}} [/tex]

[tex]\rule{200}4[/tex]

Again ,

[tex]\longrightarrow m\angle TSV = x + 5y \\ [/tex]

[tex]\longrightarrow m\angle TSV = 40^o 5(20^o)\\[/tex]

[tex]\longrightarrow m\angle TSV = 40^o + 100^o\\ [/tex]

[tex]\longrightarrow \underline{\underline{ m\angle TSV = 140^o }} [/tex]

And we are done!

[tex]\rule{200}4[/tex]

Step-by-step explanation:

Length=l

Width=w

l=3w

Perimeter of a rectangle=2(l+w)

2(l+w)=88

l+w=44

3w+w=44

4w=44

w=11

l=3w=33

Answer:

[tex]\displaystyle y = \frac{1}{2}sin\:524\pi{x}[/tex]

Step-by-step explanation:

[tex]\displaystyle \boxed{y = \frac{1}{2}cos\:(524\pi{x} - \frac{\pi}{2})} \\ \\ y = Acos(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 0 \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \hookrightarrow \boxed{\frac{1}{1048}} \hookrightarrow \frac{\frac{\pi}{2}}{524\pi} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{\frac{1}{262}} \hookrightarrow \frac{2}{524\pi}\pi \\ Amplitude \hookrightarrow \frac{1}{2}[/tex]

OR

[tex]\displaystyle y = Asin(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 0 \\ Horisontal\:[Phase]\:Shift \hookrightarrow 0 \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{\frac{1}{262}} \hookrightarrow \frac{2}{524\pi}\pi \\ Amplitude \hookrightarrow \frac{1}{2}[/tex]

You will need the above information to help you interpret the graph. First off, keep in mind that although the exercise told you to write the sine equation based on the speculations it gave you, if you plan on writing your equation as a function of cosine, then there WILL be a horisontal shift, meaning that a C-term will be involved. As you can see, the photograph on the right displays the trigonometric graph of [tex]\displaystyle y = \frac{1}{2}cos\:524\pi{x},[/tex]in which you need to replase "sine" with "cosine", then figure out the appropriate C-term that will make the graph horisontally shift and map onto the sine graph [photograph on the left], accourding to the horisontal shift formula above. Also keep in mind that the −C gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must be careful with your calculations. So, between the two photographs, we can tell that the cosine graph [photograph on the right] is shifted [tex]\displaystyle \frac{1}{1048}\:unit[/tex]to the left, which means that in order to match the sine graph [photograph on the left], we need to shift the graph FORWARD [tex]\displaystyle \frac{1}{1048}\:unit,[/tex]which means the C-term will be positive, and by perfourming your calculations, you will arrive at [tex]\displaystyle \boxed{\frac{1}{1048}} = \frac{\frac{\pi}{2}}{524\pi}.[/tex]So, the cosine graph of the sine graph, accourding to the horisontal shift, is [tex]\displaystyle y = \frac{1}{2}cos\:(524\pi{x} - \frac{\pi}{2}).[/tex]Now, with all that being said, in this case, sinse you ONLY have the exercise to wourk with, take a look at the above information next to [tex]\displaystyle Wavelength\:[Period].[/tex]It displays the formula on how to define each wavelength of the graph. You just need to remember that the B-term has [tex]\displaystyle \pi[/tex]in it as well, meaning both of them strike each other out, leaving you with just a fraction. Now, the amplitude is obvious to figure out because it is the A-term, so this is self-explanatory. The midline is the centre of your graph, also known as the vertical shift, which in this case the centre is at [tex]\displaystyle y = 0,[/tex]in which each crest is extended one-half unit beyond the midline, hence, your amplitude. So, no matter what the vertical shift is, that will ALWAYS be the equation of the midline, and if viewed from a graph, no matter how far it shifts vertically, the midline will ALWAYS follow.

If x  represent the number of seconds then the function is f(x)=0.5sin(52π(x))

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Given that the middle C key on a piano has a frequency of 262 cycles per second.

Frequency = 262

It has an amplitude of 0.5 unit

Amplitude = 0.5

We have to find the function.

y=Asin(2πf(x))

A is amplitude and f is the function.

y=0.5sin(2π262(x))

y=0.5sin(52π(x))

Hence, if x  represent the number of seconds then the function is f(x)=0.5sin(52π(x))

Answer:

.23

Step-by-step explanatio

45 of the seeds will be yellow. So the probability of a yellow flower is

45/300 = .15

Total probability = probability of white + probability of yellow + probability of red

or

1 = P(W) + P(Y) + P(R)

we know P(W) = .62. So let x = probability of a red flower

1 = .62 + .15 + x

1 = .77 + x

x = .23

Answer:

6,000,000

Explanation:

42,000 acres is the area you get after you multiply the number of acres of old-growth trees by 0.7%. So you would divide 42,000 by 0.7% to get the number of acres of old-growth trees.

# of acres of old-growth trees * 0.7% = 42,000

# of acres of old-growth trees = 42,000/0.7%

# of acres of old-growth trees = 6,000,000

PS. 0.7% = 0.007

Answer:

None of the above

Step-by-step explanation:

According to the divergence test, if the limit of a sequence as n approaches infinity does not equal 0, then the series diverges.  (Notice that if the limit does equal 0, the series doesn't necessarily converge).

According to the geometric series test, a geometric series converges if -1 < r < 1, and diverges otherwise.

The first series is a geometric series with r = -5/3.  So it diverges.

The second series is also a geometric series:

3ⁿ⁻¹ / 2ⁿ = ⅓ (3ⁿ / 2ⁿ) = ⅓ (3/2)ⁿ

r = 3/2, so it diverges.

For the third series, the limit as n approaches infinity equals 1.  This fails the divergence test, so this series also diverges.

For the fourth series, the limit as n approaches infinity equals 1.  This fails the divergence test, so this series also diverges.

Answer:

Distance between  the observer and the red car is [tex]250 Sin \frac{\pi}{3}t[/tex]

Step-by-step explanation:

Diameter of field = 500 m

Radius of field =[tex]\frac{Diameter}{2}=\frac{500}{2}=250 m[/tex]

Let R be the radius and the speed at which the car completes race be w

So,[tex]w=\frac{2\pi}{T}[/tex]

Car finished 5 laps in minutes = 30

Car finished 1 lap in minutes = [tex]\frac{30}{5}=6[/tex]

So, [tex]w=\frac{2\pi}{6}=\frac{\pi}{3}[/tex]

Refer the attached figure

Angle between car and observer = wt

So, Distance between  the observer and the red car is give as A sin wt

So, Distance between  the observer and the red car=[tex]250 Sin \frac{\pi}{3}t[/tex]

Answer:

13.1 cm² (nearest tenth)

Step-by-step explanation:

Use the sine rule for area of a triangle with 2 sides and an included angle (SAS).

Sine rule for area

[tex]\textsf{Area ABC}=\dfrac12ab \sin C[/tex]

(where [tex]a[/tex] and [tex]b[/tex] are the side lengths and [tex]C[/tex] is the included angle)

Given:

[tex]\implies \textsf{Area}=\dfrac12\cdot 8 \cdot 7 \cdot\sin (28\textdegree)[/tex]

               [tex]=13.14520376...[/tex]

               [tex]= 13.1 \textsf{ cm}^2 \textsf{ (nearest tenth)}[/tex]

Use sine rule

Area:-

[tex]\\ \sf\longmapsto \dfrac{1}{2}Base\times Height sin\theta[/tex]

[tex]\\ \sf\longmapsto \dfrac{1}{2}(8)(7)sin28[/tex]

[tex]\\ \sf\longmapsto 28sin28[/tex]

[tex]\\ \sf\longmapsto 13.1cm^2(Approx)[/tex]

By rewriting the linear function we will see that the correct option is A.

"an increasing line that passes through (0, 4)"

Here we have the linear function:

2y  = 4x + 8

We can rewrite it to get the function in the slope-intercept form:

y = (4x + 8)/2

y = 2x + 4.

So, the slope is positive, this implies that we will have an increasing line.

We also can see that the y-intecept is 4, this means that the line passes through the point (0, 4).

From that, we can conclude that the correct option is A.
