If 45 girls participated in basketball, then how many students
are in the girls athletics program?
Answer:
150
Step-by-step explanation:
Let there are 'x' girls. According to the given chart, 30% of the total girls participitated in basketball. As well as, we are provided with the statement '45 girls participated in basketball'
=> 30% of x = 45
=> 30/100 × x = 45
=> x = 45 x 100/30
=> x = 150
What is the area of major sector DFE?
A. 157.86 square cm
B. 133.94 square cm
C. 132.54 square cm
D. 125.57 square cm
Answer:
Step-by-step explanation:
Area of the circle = πr² = π7.3² = 53.29π
Area of major sector = 53.29π(285/360) ≈ 132.54 cm²
The area of major sector DFE is 132.5 sq.cm , Option C is the right answer.
What is a Major Sector ?The region bounded by the two radii and intercepted arc in a circle is called a sector .
The angle made by the radii to the center of the circle is called central angle .
if the measure of the angle is less than 180 degree then it is called minor sector and if the angle is more than 180 degree , it is called Major Sector.
It is given that
The radii of the circle is 7.3 cm
The angle subtended by the major sector at the center is 285 degree.
The area of the sector is given by
= ([tex]\rm \theta[/tex] / 360) * Area of the circle
Area of the circle is πr²
Area of the sector = ( 285 / 360) * (22/7) * (7.3)²
Area of the sector is 132.5 sq.cm
Therefore , The area of major sector DFE is 132.5 sq.cm , Option C is the right answer.

In triangle UVW, u = 20, v = 47. and w = 60. To find m∠ W,
which law would you use? Laws of Sines or Laws of Cosines? and why?
Answer:
We would use the Law of Cosines to solve the question.
m∠ W = 121.8°
Step-by-step explanation:
In triangle UVW, u = 20, v = 47. and w = 60. To find m∠ W,
which law would you use?
The Law we would use to find find m∠W is the Law of cosines, this is because in the question above we are given 3 known sides of a triangle and we are asked to find an unknown angle.
Law of cosines when we are to find an unknown angle =
m∠ W = arc cos [u² + v² - w²/ 2uv]
m∠ W = arccos [ 20² + 47² - 60²/ 2 × 20 × 47]
m∠ W = 121.81159°
Approximately = 121.8°

OR
[tex]\displaystyle \boxed{y = 2sin\:\frac{4}{13}\pi{x} - 4} \\ \\ 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 -4 \\ Horisontal\:[Phase]\:Shift \hookrightarrow 0 \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{6\frac{1}{2}} \hookrightarrow \frac{2}{\frac{4}{13}\pi}\pi \\ Amplitude \hookrightarrow 2[/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 = 2cos\:\frac{4}{13}\pi{x} - 4,[/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 approximately shifted [tex]\displaystyle 1\frac{5}{8}\: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 1\frac{5}{8}\:unit,[/tex]which means the C-term will be positive, and by perfourming your calculations, you will arrive at [tex]\displaystyle \boxed{1\frac{5}{8}} = \frac{\frac{\pi}{2}}{\frac{4}{13}\pi}.[/tex]So, the cosine graph of the sine graph, accourding to the horisontal shift, is [tex]\displaystyle y = 2cos\:(\frac{4}{13}\pi{x} - \frac{\pi}{2}) - 4.[/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 approximately hits [tex]\displaystyle [-6\frac{1}{2}, -4],[/tex]from there to the y-intercept of [tex]\displaystyle [0, -4],[/tex]they are obviously approximately [tex]\displaystyle 6\frac{1}{2}\:units[/tex]apart, telling you that the period of the graph is [tex]\displaystyle 6\frac{1}{2}.[/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 = -4,[/tex]in which each crest is extended two units beyond the midline, hence, your amplitude. So, no matter how far the graph shifts vertically, the midline will ALWAYS follow.
**Now, the maximum value is the highest possible value the graph touches, and in this case, the graph's highest peaks cycle around [tex]\displaystyle y = -2,[/tex]therefore the maximum of this sinusoidal function is [tex]\displaystyle -2.[/tex]
