The sequence of transformations that maps DOG to D'O'G' is a rotation of about 90 degrees of the origin, followed by a translation of 5 units right.

Rotation is a physical phenomenon where an object spins around an axis. It is a type of circular motion where an object moves in a circular path around a central point.

To accomplish this transformation, first, the point representing the letter D is rotated 90 degrees clockwise around the origin so that it is now pointing in the same direction as the letter O. After that, the point representing the letter D is translated 5 units to the right, resulting in the final transformation of DOG to D'O'G'.

Thus, the sequence of transformations that maps DOG to D'O'G' is a rotation of about 90 degrees of the origin, followed by a translation of 5 units right.

A sinusoidal function is a type of periodic function that can be written in the form y = a sin(bx + c) + d, where a is the amplitude, b is the frequency, c is the phase shift, and d is the vertical shift.

Given the parameters in the question, we can plug them into the general form of a sinusoidal function to find the specific function.

Amplitude = 4
Period = 3π
Vertical shift = -8

The period of a sinusoidal function is related to the frequency by the equation period = (2π)/b. Therefore, we can solve for b to find the frequency:

3π = (2π)/b

b = (2π)/(3π)

b = 2/3

Plugging in the given values for amplitude, frequency, and vertical shift, we get the sinusoidal function:

y = 4 sin((2/3)x) - 8

This is the sinusoidal function that satisfies the given conditions. It has an amplitude of 4, a period of 3π, and a vertical shift down 8 units.

The area of the shape formed from rectangle ABDE is 78 cm².

To find the area of the compound shape, we need to find the area of rectangle ABDE and triangle BCD separately and then add them.

The rectangle ABDE has a length of 15 cm (DE) and a width of 4 cm (AB). Therefore, its area is:

Area of rectangle = length x width = 15 cm x 4 cm = 60 cm²

The triangle BCD has a base of 4 cm (BC) and a height of 9 cm (BD). Therefore, its area is:

Area of triangle = 1/2 x base x height = 1/2 x 4 cm x 9 cm = 18 cm²

Now, add the areas of the rectangle and the triangle to find the total area of the compound shape:

Total area = Area of rectangle + Area of triangle = 60 cm² + 18 cm² = 78 cm²

The domain of the correspondence is {-3, -2.5, 0, 4} and the range is {3, 9, -10}. This correspondence is not a function because it is not a one-to-one correspondence; for example, both -3 and 4 are mapped to the same value of 3.

The question is asking for the domain, range, and whether the correspondence is a function for the given set of ordered pairs: {(-3,3), (-2.5), (0,9), (4,-10)}.

The domain of a correspondence is the set of all possible input values. In this case, the domain is the set of x-values from the ordered pairs: {-3, -2.5, 0, 4}.

The range of a correspondence is the set of all possible output values. In this case, the range is the set of y-values from the ordered pairs: {3, -5, 9, -10}.

A correspondence is a function if each input (x-value) is associated with only one output (y-value). To determine if the given correspondence is a function, we need to check if any x-value is repeated with a different y-value.

In this case, there are no repeated x-values, so each x-value is associated with only one y-value. Therefore, the correspondence is a function.

Answer:-12

Step-by-step explanation:

To solve for y, we can use the second equation to isolate x and substitute the result into the first equation:

2x - 5y = 72

2x = 5y + 72

x = (5y + 72)/2

Now we can substitute this expression for x into the first equation:

3x + 4y = -30

3((5y + 72)/2) + 4y = -30

Simplifying the left side:

(15/2)y + 108 + 4y = -30

Combining like terms:

(23/2)y = -138

Dividing both sides by (23/2):

y = -138 * 2/23

Simplifying:

y = -12

Therefore, the value of y that satisfies both equations is -12.

To subtract rational expressions with common denominators, we simply subtract the numerators and keep the same denominator.

In this case, our common denominator is (z^(2)+4z-12),  so we can subtract/add the numerators:

So, we will subtract the numerators, (z) - (2), and keep the same denominator:
(z)/(z^(2)+4z-12)-(2)/(z^(2)+4z-12) = (z - 2)/(z^(2)+4z-12)

Now, we can simplify the numerator by combining like terms:
(z - 2)/(z^(2)+4z-12) = (z - 2)/(z^(2)+4z-12)

Since the numerator and denominator cannot be simplified any further, this is our final answer:

I'm guessing you need the volume of the bead with the hole.

We need to get the volume of two objects; a cube and a cylinder. We need the cylinder for the hole.

V(square) = 6^3

V(square) = 216 mm^3

V(cylinder) = pi(r^2)(h)

pi(1.5^2)(6)

Radius is half the diameter, and 6 represents the height, since it's as long as the cube.

The manufacturer should ship 0 refrigerators to warehouse A and 80 refrigerators to warehouse B to minimize costs. The minimum cost is $800.

The objective of the problem is to minimize the cost of shipping the refrigerators to the two warehouses while also meeting the requirements of shipping at least 100 refrigerators and hiring at least 300 workers. This can be formulated as a linear programming problem with the following decision variables:

x1 = the number of refrigerators shipped to warehouse A
x2 = the number of refrigerators shipped to warehouse B

The objective function is the total cost of shipping the refrigerators:

minimize 12x1 + 10x2

The constraints are the requirements of shipping at least 100 refrigerators, hiring at least 300 workers, and the maximum capacity of each warehouse:

x1 + x2 >= 100
4x1 + 2x2 >= 300
x1 <= 75 (100 - 25)
x2 <= 80 (100 - 20)

Using the graphical method, we can plot the constraints and find the feasible region. The optimal solution will be at one of the corner points of the feasible region.

After plotting the constraints and finding the feasible region, we can evaluate the objective function at each of the corner points to find the minimum cost. The corner points and their corresponding costs are:

(75, 0) -> 12(75) + 10(0) = $900
(0, 80) -> 12(0) + 10(80) = $800

The answer of the given question based on the Equation is given the solution to the given equation is n = 21/4.

A quadratic equation is type of equation in an algebra that involves variable (usually represented by x) that  raised to the second power (i.e., squared). The general form of the quadratic equation are given,

[tex]ax^2+bx+c = 0[/tex]

The highest power of  variable is 2, hence , name "quadratic".

To solve this equation, we can start by simplifying each of the terms on both sides of the equation:

3n + √(n² + 8) + 3√(n² + 8) - √(n² + 8) = 8

Combining like terms, we get:

3n + 3√(n² + 8) = 8

Subtracting 3√(n² + 8) from both sides, we get:

3n = 8 - 3√(n² + 8)

Dividing both sides by 3, we get:

n = (8/3) - (√(n² + 8)/3)

Now, we can rearrange this equation to isolate the radical term on one side of the equation:

√(n² + 8)/3 = (8/3) - n

by Squaring both the sides of equation, we get:

n² + 8 = 64/9 - (16n/3) + n²

Simplifying this equation, we get:

16n/3 = 56/9

Dividing both sides by 16/3, we get:

n = 21/4

Answer:

Scalene triangle

Step-by-step explanation:

To determine the type of triangle, we need to compare the lengths of the sides to each other.

If all three sides have the same length, it's an equilateral triangle.

If two sides have the same length and the third is different, it's an isosceles triangle.

If all three sides have different lengths, it's a scalene triangle.

Using the lengths given, we see that all three sides have different lengths, so this is a scalene triangle.

Answer:

an obtuse triangle.

Step-by-step explanation:

To determine the type of triangle with sides of lengths 2, 6, and 7, we can use the triangle inequality theorem. This theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

In this case, we can check whether this condition holds for the three sides of lengths 2, 6, and 7:

2 + 6 > 7 (True)

6 + 7 > 2 (True)

2 + 7 > 6 (True)

Since all three inequalities are true, the given lengths of 2, 6, and 7 form a valid triangle.

To determine the type of triangle, we can use the lengths of the sides and the Pythagorean theorem or trigonometric functions. For this triangle, we can use the Pythagorean theorem to find that the longest side (7) is opposite the largest angle, which is greater than 90 degrees. Therefore, this triangle is an obtuse triangle.

Answer:

Based on the data in the table, we can set up a system of equations to represent the relationship between the number of imports (f(x)) and the number of exports (g(x)):

2x + 3y = z (Equation 1)

4x + 4y = z (Equation 2)

6x + 5y = z (Equation 3)

8x + 6y = z (Equation 4)

In this system, x represents the month number (January = 1, February = 2, etc.), y represents the number of exports, and z represents the total trade (exports plus imports). Each equation represents the data for a specific month.

To solve the system, we can use any method of solving systems of linear equations, such as substitution or elimination. However, we can also observe a pattern in the coefficients of the variables:

2 3 5 8

4 4 6 8

We can see that the coefficients of the x-term (the month number) increase by 2 each time, and the coefficients of the y-term (the number of exports) increase by 1 each time. This suggests that the equation for the nth month (where n is an integer between 1 and 4) can be expressed as:

2n + (n+2)y = z

We can test this by plugging in the values of n and y from any of the given months and verifying that the resulting value of z matches the actual value for that month. For example, if we use the data for March (n=3, y=5), we get:

2(3) + (3+2)(5) = z

6 + 25 = 31

And we can see that the actual value of z for March is indeed 31, which confirms that our equation works.

Using this equation, we can find the solution to the system for any given month by plugging in the appropriate values for n and y. For example, to find the total trade (z) for May (which would correspond to n=5), we can plug in n=5 and solve for z:

2(5) + (5+2)y = z

10 + 7y = z

To find the number of exports for May, we can plug in n=5 and solve for y:

2(5) + (5+2)y = z

10 + 7y = z

10 + 7y = 10 + 2y + 3

5y = -3

y = -3/5

However, since exports cannot be negative, this solution is not valid. This suggests that the data given in the table only applies to the months of January through April, and we cannot use this equation to find the solution for any month beyond April.

In summary, the system of equations represents the relationship between the number of imports and exports for each month from January to April. By observing the pattern in the coefficients of the equations, we can derive a general equation that can be used to find the total trade for any month between January and April. However, we cannot use this equation to find the solution for any month beyond April, as there is not enough data to determine the number of imports and exports for those months.

  E.  ∆ABE is isosceles

Step-by-step explanation:

Given ∠BAD ≅ ∠BED in ∆ABE you want to know what can be concluded.

An isosceles triangle has sides of equal measure opposite angles of equal measure. The base angles A and E in triangle ABE are given as congruent, so we can conclude ∆ABE is isosceles.

The answer using positive exponents only is 16x^(24)y^(16).

To simplify the expression (2x^(6)y^(4))^(4), we need to use the properties of exponents. Specifically, we need to use the property that states (a^(m))^n = a^(m*n). This means that when we raise a power to another power, we multiply the exponents.

Using this property, we can simplify the expression as follows:

(2x^(6)y^(4))^(4) = 2^(4) * x^(6*4) * y^(4*4) = 16 * x^(24) * y^(16)

So, the simplified expression is 16x^(24)y^(16).

Therefore, the answer using positive exponents only is 16x^(24)y^(16).
