The area of the given kite is,

⇒ A = 26 units²

Now, In this case we have that the area of the kite is given by the area of two triangles,

And, the triangles share the same base with length,

2 + 2 = 4.

And, One of the triangles has height of 6 and the other has height of 7.

So, the total area of kite is,

A = 1/2 × 4 × 6 + 1/2 × 4 × 7

A = 12 + 14

A = 26 units²

Therefore, The area of the given kite is,

⇒ A = 26 units²

The range is 5 years.The median is 18 years.

To determine the range and median from the given dot plot of ages, we need to analyze the distribution of the data points.

The range represents the difference between the maximum and minimum values in a dataset. Looking at the dot plot, the minimum age appears to be 16, while the maximum age is 21. Therefore, the range can be calculated as:

Range = Maximum age - Minimum age = 21 - 16 = 5 years.

Thus, the range of the ages of employees at the summer camp is 5 years.

The median represents the middle value in a dataset when it is arranged in ascending or descending order. To determine the median, we need to organize the ages in order from least to greatest:

16, 17, 18, 19, 20, 21

Since there are six data points, the median would be the value in the middle. In this case, the median would be the third value, which is 18.

Therefore, the median of the ages of employees at the summer camp is 18 years.

Answer:

1 is a

2 is c

3 is b

Step-by-step explanation:

A) Yes, (x+2) is a factor of the function, because the remainder is zero.

B) All the factor are,

⇒ (x + 2) (x² - 5x + 3)

C) All the zeroes are,

x = - 2

x = (5 ± √13)/2

Given that;

Function is,

⇒ f (x) = x³ - 3x² - 7x + 6

Now, We can check (x + 2) is a factor of function or not as;

If x + 2 is a factor of function, then x = - 2 is satisfy the function.

So, Put x = - 2;

⇒ f (x) = x³ - 3x² - 7x + 6

⇒ f (- 2) = (- 2)³ - 3 (- 2)² - 7 (- 2) + 6

⇒ f (- 2) = - 8 - 12 + 14 + 6

⇒ f (- 2) = 0

Thus, (x + 2) is a factor of the function,

Hence, We can find all the zeroes as;

(x + 2) ) x³ - 3x² - 7x + 6 (x² - 5x + 3

          x³ + 2x²

         ------------

              - 5x² - 7x

              - 5x² - 10x

              ----------------

                       3x + 6

                       3x + 6

                      ------------

                              0

Thus, We get;

⇒ x³ - 3x² - 7x + 6

⇒ (x + 2) (x² - 5x + 3)

Since, x² - 5x + 3 = 0

x = - (- 5) ± √(- 5)² - 4×1×3 / (2×1)

x = (5 ± √25 - 12) / 2

x = (5 ± √13)/2

Thus,

A) Yes, (x+2) is a factor of the function, because the remainder is zero.

B) All the factor are,

The side length x and y of the right triangle are  [tex]\frac{8\sqrt{3} }{3}[/tex] and  [tex]\frac{16\sqrt{3} }{3}[/tex] respectively.

The figure in the image is a right triangle.

Angle θ = 60°

Opposite to angle θ = 8

Adjacent to angle θ = x

Hypotenuse = y

To solve for side lengths x and y, we use the trigonometric ratio.

Note that:

sine = opposite / hypotenuse

cosine = adjacent / hypotenuse

tangent = opposite / adjacent

First, we determine the value of x.

tanθ = opposite / adjacent

tan( 60 ) = 8/x

x = 8/tan( 60 )

x = [tex]\frac{8\sqrt{3} }{3}[/tex]

Next, solve for y:

sinθ = opposite / hypotenuse

sin( 60 ) = 8/y

y = 8/sin( 60 )

y = [tex]\frac{16\sqrt{3} }{3}[/tex]

Therefore, the value of x is  [tex]\frac{8\sqrt{3} }{3}[/tex] and the value of y is  [tex]\frac{16\sqrt{3} }{3}[/tex].

The actual distance from the starting point to the ending point is 39.96 miles.

For someone working with the map or scaled drawing, we can define the scale factor as the ratio between a distance on the drawing or map and the corresponding actual distance in the real world.

From the question,

1.5 inches on the map = 5 miles in actual distance

1 inch on the map =  x miles

Perform cross multiplication

1 inch on the map =  (5 x 1) / 1.5  = 3.33 miles/inch (scale factor)

The scale factor can then be expressed as ratio:

5/1.5 = 1:0.3

0r

5/1.5 = 10:3

So, the actual distance between the starting point and the ending point can be found by multiplying the length on the map by the scale factor:

Actual distance = Map distance x Scale factor

Actual distance = 12 inches x 3.33 miles/inch = 39.96 miles

Therefore, the actual distance from the starting point to the ending point is approximately 39.96 miles.

We have,

The given function is a quadratic function of form f(x) = ax² + bx + c, where a = -40, b = 640, and c = 0.

To find the vertex, we need to use the formula:

x = -b/2a

where a = -40 and b = 640.

So,

x = -b/2a = -640/(2(-40)) = 8

Now, we can find the y-coordinate of the vertex by plugging x = 8 into the function:

Answer:

The expression πr2h is a monomial because it is a single term that is the product of three variables: π, r2, and h. The term "mono" means "one," and "monomial" refers to a single term in algebraic expressions.

The degree of a monomial is the sum of the exponents of its variables. In this case, the degree of the monomial is 3, because the variables π, r, and h have exponents of 1, 2, and 1 respectively. Therefore, the degree of the monomial is 1 + 2 + 1 = 3.

The mean of the test is 45.

Let's use the formula for z-score:

z = (x - μ) / σ

where z is the number of standard deviations from the mean, x is the raw score, μ is the mean, and σ is the standard deviation.

For the first score of 30, we know that it falls three standard deviations below the mean:

-3 = (30 - μ) / σ

Simplifying this equation, we get:

-3σ = 30 - μ

μ = 30 + 3σ

For the second score of 60, we know that it falls three standard deviations above the mean:

3 = (60 - μ) / σ

Simplifying this equation, we get:

3σ = 60 - μ

μ = 60 - 3σ

Now we can set these two equations equal to each other, since they both equal μ:

30 + 3σ = 60 - 3σ

6σ = 30

σ = 5

Now we can plug this value of σ back into one of the equations for μ:

The shopkeeper should have sold the pen for Rs. 13.80 in order to earn a profit of 15%. Option C

To determine the selling price of the pen in order to earn a 15% profit, we can use the concept of a profit margin.

Let's start by finding the cost price of the pen. Since the shopkeeper wants to make a 10% profit when selling the pen for Rs. 13.20, we can set up the equation:

Cost price + 10% profit = Selling price

Let's assume the cost price of the pen is C. Then, we can write theequation as:

C + 0.1C = 13.20

Simplifying the equation, we have:

1.1C = 13.20

Dividing both sides by 1.1, we find:

C = 12

So, the cost price of the pen is Rs. 12.

Now, to determine the selling price that will yield a 15% profit, we can use the formula:

Selling price = Cost price + Profit

Profit is calculated as a percentage of the cost price. In this case, the profit percentage is 15%. Substituting the values, we have:

Selling price = 12 + 15% of 12

Selling price = 12 + (0.15 * 12)

Selling price = 12 + 1.8

Selling price = 13.8

Therefore, the shopkeeper should have sold the pen for Rs. 13.80 in order to earn a profit of 15%.

now, let's notice, we can't use the negative value, because the sides are never negative.

The area of triangle A is 98 sq cm. Option B is correct.

Since triangle A is a scaled version of triangle B, the ratio of their areas is equal to the square of the ratio of their corresponding side lengths.

If the dimensions of triangle A are twice the dimensions of triangle B, then the ratio of their side lengths is 2:1.

The ratio of their areas, therefore, is (2:1)² = 4:1.

Given that the area of triangle B is 24.5 sq cm, we can find the area of triangle A by multiplying 24.5 by the ratio of their areas:
