Answer:

c) [tex]\displaystyle \pi[/tex]

Step-by-step explanation:

[tex]\displaystyle \boxed{y = cos\:(2x - \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{\pi}{4}} \hookrightarrow \frac{\frac{\pi}{2}}{2} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{\pi} \hookrightarrow \frac{2}{2}\pi \\ Amplitude \hookrightarrow 1[/tex]

OR

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

You will need the above information to help you interpret the graph. First off, keep in mind that although this looks EXACTLY like the sine graph, 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 = cos\:2x,[/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{\pi}{4}\: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{\pi}{4}\:unit,[/tex]which means the C-term will be positive, and by perfourming your calculations, you will arrive at [tex]\displaystyle \boxed{\frac{\pi}{4}} = \frac{\frac{\pi}{2}}{2}.[/tex]So, the cosine graph of the sine graph, accourding to the horisontal shift, is [tex]\displaystyle y = cos\:(2x - \frac{\pi}{2}).[/tex]Now, with all that being said, in this case, sinse you ONLY have a graph to wourk with, you MUST figure the period out by using wavelengths. So, looking at where the graph WILL hit [tex]\displaystyle [-3\pi, 0],[/tex]from there to [tex]\displaystyle [-2\pi, 0],[/tex]they are obviously [tex]\displaystyle \pi\:units[/tex]apart, telling you that the period of the graph is [tex]\displaystyle \pi.[/tex]Now, the amplitude is obvious to figure out because it is the A-term, but of cource, if you want to be certain it is the amplitude, look at the graph to see how low and high each crest extends beyond the midline. 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 unit beyond the midline, hence, your amplitude. So, no matter how far the graph shifts vertically, the midline will ALWAYS follow.

I am delighted to assist you at any time.

Step-by-step explanation:

To find percentage error you would subtracted the expected value by the actual, and then you would dive that by he actual amount. finally to get you're percent you would multiply by 100. Meaning you would do the following:

1-3=-2

-2/3=-.6666

.6666 x 100 = 66.66%

Hence, r=2cosθ represents a circle with centre (1,0) and radius 1 and (1,0) in polar coordinates too is (1,0

The name of the shape graphed by the function [tex]r^{2} = 4\;cos[/tex] θ is Limaçon with inner loop.

We have the following function -

[tex]r^{2} = 4\;cos[/tex] θ

We have to find the shape represented by this function.

Polar coordinates are used to represent a point in a two - dimensional plane. In polar coordinate system, the point under consideration is represented with the help of two variables namely [tex]r[/tex] and θ. (Take the reference from the figure attached)

We have -

[tex]r^{2} = 4\;cos[/tex] θ

The relation between variables in polar coordinates and cartesian coordinates is -

[tex]x = rcos\theta\\y=rsin\theta\\r=\sqrt{x^{2} +y^{2} }\\[/tex]

First, lets convert this equation in the rectangular coordinates -                                                      

[tex]r^{3} =4\;r\;cos\;\theta\\r\times\;r^{2} = 4\;r\;cos\;\theta\\\sqrt{x^{2} +y^{2} }\;\times\;(x^{2} +y^{2}) = 4x\\(x^{2} +y^{2})=\frac{4x}{\sqrt{x^{2} +y^{2} }}[/tex]

The above equation in rectangular coordinate system represents a Limaçon with inner loop.

Hence, the name of the shape graphed by the function [tex]r^{2} = 4\;cos[/tex] θ is

Limaçon with inner loop.

[tex]A=9600cn^2[/tex]

Step-by-step explanation:

From the question we are told that:

Ratio of square base and slant height [tex]R=6:5[/tex]

Volume [tex]V=48000cm^3[/tex]

Generally the equation for height  Pyramid h is mathematically given by

  [tex]h^2=s^2+(\frac{1}{2}a^2)[/tex]

  [tex]h=\sqrt{s^2+(\frac{1}{2}a)^2)}[/tex]

  [tex]h=\sqrt{5^2+3^2}[/tex]

  [tex]h=4[/tex]

   Where

    a= base Length

    s=slant height of pyramid

Therefore the ratio of height is

  [tex]h=4[/tex]

Generally the equation for The Volume of  Square  based Pyramid V is mathematically given by

 [tex]V=a^2\frac{h}{3}[/tex]

 [tex]V=6^2\frac{4}{3}[/tex]

 [tex]V=48[/tex]

Therefore the ratio of volume is

 V=48

Generally for V=4800

Therefore

  [tex]a=60[/tex]

  [tex]h=40[/tex]

Generally the equation for Area of Square  based Pyramid A is mathematically given by

  [tex]A=a^2+2a\sqrt{\frac{a^2}{4}+h^2 }[/tex]

 [tex]A=60^2+2(60)\sqrt{\frac{(60)^2}{4}+(40)^2}[/tex]

 [tex]A=9600cn^2[/tex]

Therefore the Area of Square  based Pyramid A is

Answer:

x = 35 and y = 100

Step-by-step explanation:

Let x = dollar cost per dive  and y = dollar cost per night.

ATQ,

4x+3y = 440 .....(1)

and

8x + 5y = 780 .....(2)

Multiply equation (1) by 2.

8x+6y = 880......(3)

Subtract equation (3) from (2).

8x + 5y -(8x+6y)= 780-880

-y = -100

y = 100

Put the value of y in equation (1).

4x+3(100) = 440

4x = 440-300

4x = 140

x = 35

Hence, the value of x is 35 and that of y is 100.

The equation of the line that is tangent to circle A from point C (2, 8) is x = 2 option (A) x = 2 is correct.

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

It is given that:

Circle A is located at (6, 5) and has a radius of 4 units.

First, find the slope of the radius

As we know, the ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

The line passes through (2, 8) and (2, 5)

y - 5 = (-3/0)(x -2)

-x + 2 = 0

x = 2

Thus, the equation of the line that is tangent to circle A from point C (2, 8) is x = 2 option (A) x = 2 is correct.
