Answer:

The amount of money they will spend at the restaurant is $35.16

Step-by-step explanation:

From the information given in the question, we have;

The amount Jessica, Genesis, and Violet received as bill at the restaurant, X = $29.30

The amount they wished to leave as tip, T = 20% (of the bill)

Therefore, the amount of money they will spend at the restaurant, 'A', is given as follows;

A = X + T

T = 20% of X = 20/100 × X = 0.2·X

∴ A = X + 0.2·X = 1.2·X

X = $29.30

A = 1.2·X = 1.2 × $29.30 = $35.16

The amount of money they will spend at the restaurant, A = $35.16

Sum of angles in a quadrilateral = 360°

360° - 128° - 40° - 82° = 110°

Answer:

x = 110

Step-by-step explanation

The sum of the interior angles of a quadrilateral = 360°

Sum the given angles and equate to 360

82 + 40 + 128 + x = 360

250 + x = 360 ( subtract 250 from both sides )

x = 110

Answer:

102 cm2

Step-by-step explanation:

First you want to find the area of the entire rectangle by multiplying the 2 sides.

20cm x 6cm = 120

Then you want to find the area of the other two shapes (in this case the square and triangle). Also use the other sides to find the lengths of the triangle.

Square = 3 x 3 = 9

triangle = 6 x 3 = 18 / 2 = 9

So then all you have to do is subtract the squares and triangles area from the total rectangle.

120 - (9 + 9)

120 - 18

102 cm2

The number of white and tie-dye t-shirt sold that week is 200 and 300 respectively

let

x + y = 500 (1)

15x + 20y = 9000 (2)

from (1)

x = 500 - y

substitute x = 500 - y into (2)

15x + 20y = 9000

15(500 - y) + 20y = 9000

7500 - 15y + 20y = 9000

- 15y + 20y = 9000 - 7,500

5y = 1500

y = 1500/5

y = 300

Substitute y = 300 into (1)

x + y = 500

x + 300 = 500

x = 500 - 300

x = 200

Therefore, the number of white and tie-dye t-shirt sold that week is 200 and 300 respectively

○ [tex]\displaystyle f(x) = 10cos\:\frac{\pi}{2}x + 10[/tex]

Step-by-step explanation:

[tex]\displaystyle \boxed{f(x) = 10sin\:(\frac{\pi}{2}x + \frac{\pi}{2}) + 10} \\ \\ 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 10 \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \hookrightarrow \boxed{-1} \hookrightarrow \frac{-\frac{\pi}{2}}{\frac{\pi}{2}} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{4} \hookrightarrow \frac{2}{\frac{\pi}{2}}\pi \\ Amplitude \hookrightarrow 10[/tex]

OR

[tex]\displaystyle 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 10 \\ Horisontal\:[Phase]\:Shift \hookrightarrow 0 \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{4} \hookrightarrow \frac{2}{\frac{\pi}{2}}\pi \\ Amplitude \hookrightarrow 10[/tex]

The cosine graph in the photograph on the right is the OPPOCITE of the cosine graph in the photograph on the left, and the reason for this is because of the negative inserted in front of the amplitude value. Whenever you insert a negative in front of the amplitude value of any trigonometric equation, the whole graph reflects over the midline. Keep this in mind moving forward. Now, with all that being said, no matter how far the graph shifts vertically, the midline will ALWAYS follow.

**Moreover, both graphs have the same maximum and minimum value, but we are looking for the equation that will not reflect over the midline of [tex]\displaystyle y = 10,[/tex]which means we do NOT want a negative in front of the amplitude value, therefore we have this equation:

[tex]\displaystyle f(x) = 10cos\:\frac{\pi}{2}x + 10[/tex]

If you are having trouble figuring out which graph is which, just remember that the parent function of [tex]\displaystyle y = cos\:x[/tex]never touches the origin unless it shifts one unit south or gets reflected from somewhere. In this case, the photograph on the left touches the origin because of a reflection [negative symbol], therefore the photograph on the right matches the equation selected.

I am delighted to assist you at any time.

The correct function is,

⇒ y = 10 cos (π/2x) + 10

A relation between a set of inputs having one output each is called a function.

Given that;

A cosine function has a period of 4.

Since, The period is 4.  

Hence, The relationship between period and b (the coefficient of the independent variable of the cosine function) is, (period) =(2π/b).  

Hence, We get;

⇒ 4b = 2π

⇒ b = 2π/4

⇒ b = π/2

So, Now our equation y = a cos (bx) + c becomes as;

⇒ y = 10 cos (π/2x) + 10

Thus, The horizontal center line of this cosine curve is y = 10.  The maximum value of the curve is 20, which is 10 + 10, and the minimum value is 0, which is 10 - 10.

The option which is the closest to the measure of ∠A is 74°

Step-by-step explanation:

The question is answered using the options provided by a similar question from an online source

When tan A = (7/2), we have;

The trigonometric ratio for the tangent of an angle is given as follows;

[tex]tan\angle A = \dfrac{Opposite \ leg \ length}{Adjacent \ Leg \ length} = \dfrac{sin \angle X}{cos\angle X}[/tex]

tan A = (7/2) = 3.5

sin(30°) = 1/2, cos(30°) = (√3/2)

sin(60°) = (√3/2), cos(60°) = (1/2)

sin(45°) = cos(45°) = (√2/2)

tan(30°) = (1/2)/(√3/2) = (√3)/3

tan(45°) = 1

tan(60°) = (√3/2)/(1/2) = √3

The tangent of an angle is increasing as we move from 0° to 90°

Therefore, given that tan A = 7/2 > tan 60° = √3, we have;

∠A > 60°

The option (the options obtained from an online source are; 15°, 39°, 58°, and 74°) which is the closest to the measure of ∠A is 74°.
