The area of the shaded sector is 575π/9 square units.

The area of the unshaded sector is 325π/9 square units

The value of the angle subtended by the unshaded sector is 130⁰ the value of the angle subtended by the shaded sector is 230⁰.

To find the area of a sector with radius 10 units and angle 230⁰, we can again use the same formula:

Area of sector = (angle/360) x πr^2

Substituting the values given in the formula, we get:

Area of sector = (230/360) x π(10)²

= (23/36) x 100π

= 575π/9 square units

To find the area of a sector with radius 10 units and angle 130⁰, we can use the formula:

Area of sector = (angle/360) x πr^2

Substituting the values given in the formula, we get:

Area of sector = (130/360) x π(10)^2

= (13/36) x 100π

= 325π/9 square units

Explanation:

I'll use x in place of 'a'

I'll also use y in place of b.

The equation 5a+b = 7 turns into 5x+y = 7

Solve for y to get

5x+y = 7

y = -5x+7

This is in slope-intercept form y = mx+b

The negative reciprocal of the slope is 1/5. Flip the fraction and flip the sign. So if -5 is the original slope, then 1/5 is the perpendicular slope.

Of the answer choices, only choice C has a slope of 1/5. Think of b = (1/5)a-2 as y = (1/5)x - 2

Therefore, choice C is the answer.

The equation of a line that is perpendicular to '5a+b = 7' is 'b = (1/5)a + c'. Therefore, the correct option among given choices is 'b = (1/5)a - 2' (option C).

To start with, the given line's equation, 5a + b = 7, can be converted to slope-intercept form (b = mx + c), where m represents the slope of line, and 'c' is the y-intercept.

Converting the equation, 5a + b = 7, we get b = -5a + 7. This tells us the slope of our original line is -5.

Lines that are perpendicular to each other have slopes that are negative reciprocals of each other. So, the line perpendicular to the one with a slope of -5 would have a slope of 1/5. Therefore, the equation of a line perpendicular to '5a+b = 7' would be in the form 'b = (1/5)a + c'.

Thus, the correct answer is option C : b = (1/5)a - 2.

Answer:

To determine when each company is projected to break even, Jami needs to find the point where the Cost and Revenue equations intersect. This point will represent the month when the business is projected to break even, as the Cost and Revenue will be equal.

Using the given equations, we can set the Cost equation equal to the Revenue equation for each business:

Blysis: -13124.3190x + 3586 = -6941915384x + 21954

Solving for x, we get x = 0.00057 months.

Since this value is extremely small, we can assume that Blysis is already profitable.

Appster: -13124.3190x + 3586 = -6941915384x + 21954

Solving for x, we get x = 0.00057 months.

Since this value is extremely small, we can assume that Appster is already profitable.

Enrich: -3586x - 21954 = -6941915384x + 13174

Solving for x, we get x = 0.0035 months.

Since this value is also very small, we can assume that Enrich is already profitable.

Green Team: 178420.64421x - 68419 = -4289115387x + 13174

Solving for x, we get x = 0.0009 months.

Since this value is extremely small, we can assume that Green Team is already profitable.

Southwest Fusion: -13124.3190x + 4289115387x = 13174

Solving for x, we get x = 35.23 months.

This value indicates that Southwest Fusion is projected to break even in approximately 35 months.

Zoo to You: -13124.3190x + 54209539 = -10381x

Solving for x, we get x = 4.05 months.

This value indicates that Zoo to You is projected to break even in approximately 4 months.

Based on these projections, Jami should recommend Blysis, Appster, Enrich, and Green Team to the investor, as they are already profitable or expected to break even within the next 24 months. Southwest Fusion and Zoo to You may not be as attractive for investment, as they are projected to take longer to become profitable.

Step-by-step explanation:

With an eye level of 35 feet above the water, you can see approximately 7.24 miles to the horizon.

Multiplication is a mathematical operation that involves combining two or more numbers to find their total or product. It is often denoted by the symbol "×" or "*", and the result of multiplication is called the product. For example, multiplying 3 and 4 gives a product of 12, written as 3 × 4 = 12.

To find out how far you can see when your eye level is 35 feet above the water, we can use the given formula:

d = √(3h/2)

Plugging in h = 35, we get:

d = √(3 * 35/2)

d = √(105/2)

d = √52.5

d ≈ 7.24

So, when your eye level is 35 feet above the water, you can see approximately 7.24 miles to the horizon. Keep in mind that this is an approximation and actual visibility may vary due to factors such as atmospheric conditions and the height of objects obstructing the view.

Therefore, With an eye level of 35 feet above the water, you can see approximately 7.24 miles to the horizon.

Answer:

  graph 4 (reflected vertically)

Step-by-step explanation:

You want the graph that represents a cosine function with no horizontal shift, an amplitude of 2, and a period of 2π/3.

The amplitude of a sine or cosine function is the difference between the positive peak and the centerline. All of the graphs show functions with an amplitude of 2.

The period of the function is the difference of x-values between the first instance of the function and the first repeat: f(x) ≡ f(x+p) has a period of p.

Graphs 1 and 3 show periods of 2π/9; graphs 2 and 4 show periods of 2π/3, as required.

There is an interaction between horizontal shift and vertical reflection. Sine or cosine functions are effectively inverted (reflected over the x-axis) if they are shifted horizontally by 1/2 period—and vice versa.

The function in graph 3 is a sine function, or a horizontally shifted cosine function.

The function in graph 4 is a cosine function that has been shifted 1/2 perior, OR a cosine function that has been reflected over the x-axis.

Graph 4 is the only viable choice for a cosine function with the correct period, so we have to assume it starts at -2 because it has been reflected vertically over the x-axis. (There seems to be no restriction on that in the problem statement.)

Ordinarily, you might not be expected to make any assumptions about vertical reflection. It seems a bit of a trick question.

Step-by-step explanation:

Use Trigonometric Expansion.

Verify the following identity:

[tex]cos(x)^2(tan(x)^2+1)=1[/tex]

Write tangent as [tex]\frac{sine}{cosine}[/tex]

[tex]cos(x)^2(\frac{sin(x)}{cos(x)} ^2+1)=1[/tex]

[tex]cos(x)^2(\frac{sin(x)}{cos(x)} ^2+1)=cos(x)^2(\frac{sin(x)^2}{cos(x)^2+1} )[/tex]

[tex](cos(x)^2(\frac{sin(x)^2}{cos(x)^2} +1))=1[/tex]

Put sin(x)^2/cos(x)^2 +1 over the common denominator cos(x)^2 : sin(x)^2/cos(x)^2+1 = cos(x)^2+sin(x)^2 /cos (x)^2:

cos(x)^2(cos(x)^2+sin(x)^2/cos(x)^2)=1

Cancel cos(x)^2 from the numerator to the denominator.

cos(x)^2(cos(x)^sin(x)^2)/cos(x)^2=cos(x)^2(cos(x)^2+sin(x)^2)/cos(x)^2=cos(x)+sin(x)^2:

In the end, Reggie has 435.2 stamps and Cοrwin has 179.2 stamps.

The fοur basic mathematical οperatiοns are Additiοn, subtractiοn, multiplicatiοn, and divisiοn.

Let's start by assigning variables tο represent the number οf stamps each persοn has.

Let x be the cοmmοn factοr, sο Reggie has 8x stamps, Tοm has 4x stamps, and Cοrwin has 5x stamps.

After Cοrwin gave 3/10 οf his stamps tο Reggie and Tοm, he had (1-3/10) οr 7/10 οf his οriginal number οf stamps, οr 7/10(5x) = 7x/2 stamps.

Reggie and Tοm each received 3/20 οf Cοrwin's οriginal number οf stamps, οr 3/20(5x) = 3x/4 stamps.

Sο Reggie nοw has 8x + 3x/4 stamps = 35x/4 stamps, and Tοm has 4x + 3x/4 stamps = 19x/4 stamps.

We are alsο given that Cοrwin had 192 less stamps than Reggie after the exchange, sο:

5x = 35x/4 - 192

Multiplying bοth sides by 4 tο get rid οf the fractiοn:

20x = 35x - 768

Subtracting 20x frοm bοth sides:

15x = 768

Dividing bοth sides by 15:

x = 51.2

Sο Reggie has 8x = 409.6 stamps, Tοm has 4x = 204.8 stamps, and Cοrwin has 5x = 256 stamps.

If Tοm's number οf stamps increased by 30%, he nοw has 130% οf his οriginal number οf stamps, οr 1.3(204.8) = 266.24 stamps.

Finally, adding up the number οf stamps each persοn nοw has:

Reggie: 409.6 + 3x/4 = 409.6 + 3(51.2)/4 = 435.2 stamps

Tοm: 266.24 stamps

Cοrwin: 7x/2 = 7(51.2)/2 = 179.2 stamps

Since the vertex is (0, -4), we know that the equation of the parabola will have the form:

y = a(x - 0)^2 - 4

where "a" is the coefficient that determines whether the parabola opens up or down.

To find the value of "a", we can use the fact that the parabola passes through the point (10, 1):

1 = a(10 - 0)^2 - 4

1 + 4 = 100a

5 = 100a

a = 1/20

Substituting this value of "a" into the equation for the vertex form, we get:

y = (1/20)x^2 - 4

So the equation of the parabola in vertex form is y = (1/20)x^2 - 4, with vertex (0, -4) and passing through (10, 1).

Since the question is asking about total employees, we must add 175 to 500 to get 675. Therefore, the correct answer is 675.

Increase means to grow or make larger in size, amount, degree, or intensity. It is the opposite of decrease, meaning to make or become less.

This is because when there were 500 employees, a 35% increase would be a total of 500 + 35% of 500

= 500 + 175

= 675.

To calculate 35% of 500, we use the formula:

(35/100) × 500 = 175

This means that 35% of 500 is 175, so when we add 175 to 500, we get 675.

Since the question is asking about  total employees, we must add 175 to 500 to get 675.

       First, we will solve for the area of the triangles. Since they are congruent, we will multiply the height times the base. Usually, you would have to divide by two. However, since we have two congruent triangles, we will not be doing this.

       A = BH

       A = (2 m)(6 m)

       A = 12 m²

       Next, we will find the area of the rectangle. We will multiply the length by the width.

       A = BH

       A = (6 m)(4 m)

       A = 24 m²

       Lastly, we will add these two values together.

24 m² + 12 m² = 36 m²
