The dimension of the new classroom is 8 meters of length and 5 meters of width.

Area of a two dimensional shape is the total region which is bounded by the object's shape.

Given that,

Area of the classroom = 20 square meters

Let x be the length and y be the width of the classroom.

Area of a rectangular classroom = Length × Width.

So, we get an equation,

xy = 20

x = 20/y [Equation 1]

If length is increased by 3 meters and the width is increased by 1 meter, the classroom will double in area.

(x + 3) (y + 1) = 20 × 2

(x + 3) (y + 1) = 40  [Equation 2]

Substitute [Equation 1] in [Equation 2]

((20/y) + 3) (y + 1) = 40  

Multiplying,

20 + 3y + (20/y) + 3 = 40

3y + (20/y) = 40 - 23

3y + (20/y) = 17

Multiplying throughout by y,

3y² + 20 = 17y

3y² - 17y + 20 = 0

3y² - 12y - 5y + 20 = 0

3y (y - 4) - 5 (y - 4) = 0

(3y - 5) (y - 4) = 0

3y - 5 = 0 or y - 4 = 0

y = 5/3 or y = 4

Let y = 4, then x = 20/4 = 5

Dimension of the new classroom is (x+3) = 8 meters and (y+1) = 5 meters

Hence the dimension of the new classroom is 8 meters and 5 meters.

The determinant of a 3x3 matrix can be found using the following formula:
\[ \left|\begin{array}{ccc} a & b & c \\ d & e & f \\ g & h & i \end{array}\right| = a(ei - fh) - b(di - fg) + c(dh - eg) \]

In this case, we can substitute the values from the given matrix into the formula:
\[ \left|\begin{array}{ccc} d+b & d & d \\ d & d+b & d \\ d & d & d+b \end{array}\right| = (d+b)((d+b)(d+b) - d^2) - d(d(d+b) - d^2) + d(d^2 - d(d+b)) \]
Simplifying the expression gives:
\[ = (d+b)(d^2 + 2bd + b^2 - d^2) - d(d^2 + bd - d^2) + d(d^2 - d^2 - bd) \]
\[ = (d+b)(2bd + b^2) - d(bd) + d(-bd) \]
\[ = 2bd^2 + 2b^2d + b^3 - bd^2 - bd^2 \]
\[ = b^3 + 2b^2d \]

Therefore, the determinant of the given matrix is \[b^3 + 2b^2d\].

The final answer is 8*2=16 ways

Eight people are to be seated in a row of 8 chairs. In how many ways can these people be seated if two of them insist on sitting next to one another?

There are a couple of steps to solving this problem.

Step 1: Consider the two people who insist on sitting next to one another as one unit. This means that there are now 7 units to be seated in the 8 chairs.

Step 2: Calculate the number of ways that the 7 units can be seated in the 8 chairs. This is done using the formula n!/(n-r)!, where n is the number of chairs and r is the number of units. In this case, n=8 and r=7, so the formula is 8!/(8-7)!, or 8!/1!, which simplifies to 8.

Step 3: Calculate the number of ways that the two people who insist on sitting next to one another can be seated within their unit. There are 2! or 2 ways that they can be seated.

Step 4: Multiply the number of ways that the 7 units can be seated in the 8 chairs by the number of ways that the two people can be seated within their unit. This gives us the total number of ways that the 8 people can be seated if two of them insist on sitting next to one another.

So the final answer is 8*2=16 ways.

The accumulated value is $A = 5000 \times e^{(0.09 \times 4)} = 7,311.12$.

The accumulated value of an investment of $\$ 5,000$ at 9% compounded continuously for 4 years is $7,311.12.

This can be calculated using the compound interest formula

\(A=P e^{\lambda t}\).

In this equation, A is the accumulated value of the investment, P is the principal investment amount (which is $\$ 5,000$), $\lambda$ is the interest rate per compounding period (which is 0.09) and t is the number of compounding periods (which is 4 years).

Therefore, the accumulated value is $A = 5000 \times e^{(0.09 \times 4)} = 7,311.12$.

Answer:

Yes, the segments with lengths 11, 12, and 20 can form a triangle.

To check this, we can use the triangle inequality theorem, which 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 that:

11 + 12 > 20

11 + 20 > 12

12 + 20 > 11

Since all three inequalities are satisfied, the segments can form a triangle.

To classify the triangle, we can use the law of cosines, which relates the lengths of the sides of a triangle to the cosine of one of its angles. Specifically, for a triangle with sides a, b, and c and angle A opposite side a, we have:

c^2 = a^2 + b^2 - 2ab cos(A)

Using this formula, we can find the cosine of each angle and determine if the triangle is acute, right, or obtuse based on the values obtained.

For the given triangle, we have:

a = 11, b = 12, c = 20

cos(A) = (b^2 + c^2 - a^2) / (2bc) = (12^2 + 20^2 - 11^2) / (2 * 12 * 20) ≈ 0.714

Since cos(A) is positive and less than 1, the angle A is acute. Similarly, we can find the cosines of the other angles:

cos(B) = (c^2 + a^2 - b^2) / (2ca) ≈ 0.943

cos(C) = (a^2 + b^2 - c^2) / (2ab) ≈ -0.519

Since cos(B) and cos(C) are both positive and less than 1, angles B and C are also acute.

Therefore, the given triangle is acute.

The value of x in the equation 8+4=2(x-1) is 7

To solve for x in the equation 8+4=2(x-1), we can follow these steps:

Simplify the left-hand side of the equation by adding 8 and 4 to get 12:

8 + 4 = 12

Simplify the right-hand side of the equation by distributing the 2 to the expression inside the parentheses:

2(x-1) = 2x - 2

Set the left-hand side and the right-hand side equal to each other:

12 = 2x - 2

Add 2 to both sides of the equation:

12 + 2 = 2x

14 = 2x

Divide both sides of the equation by 2:

14/2 = x

x = 7

Therefore, the value of x in the equation 8+4=2(x-1) is 7.

The real number t corresponds to the point P(-2/1, 2/3) on the unit circle. To evaluate the six trigonometric functions of t, we can use the coordinates of point P.

Part 2 of 6:

Part 5 of 6:

The other four trigonometric functions can be evaluated similarly using the coordinates of point P:

sint= y-coordinate of point P = 2/3

cott= x-coordinate/y-coordinate = (-2/1)/(2/3) = -3

The complete question is:

For the given triangle ABC, the exact values of the three angles are: A = 50°, B = 60°, and C = 70°.

Let ABC be a triangle. The angles A, B, and C can be determined using the fact that the sum of the angles in any triangle is 180°.

We know that

A = 5x, B = 6x, and C = 7x, so:

A + B + C = 5x + 6x + 7x = 18x

Since the sum of the angles in a triangle is 180°, we can set

18x = 180°

and solve for x:

18x = 180°, x = 10°

Therefore, A = 50°, B = 60°, and C = 70°.

The coordinates of B' after the translation represented by (x - 4, y - 3) is (1, -2). See other solutions below

B is located at the point (5, 1) in the figure.

If we translate the point by (x - 4, y - 3), the new location of B, denoted by B', can be found by subtracting 4 from the x-coordinate and 3 from the y-coordinate.

Therefore, B' is located at (1, -2).

The given information provides us with a set of matching points, which are:

Preimage = (2, 1)

Image = (-1, 2)

These points can be represented by the equation:

(x, y) = (-y, x)

This equation indicates that the points have undergone a (d) clockwise rotation of 270 degrees.

Here, the smaller shape is created by scaling down a larger shape, the transformation is a dilation that results in a reduction.

The scale factor for this transformation could be either 1/2 or 1/4.

Given the points P = (3, -2) and S = (4, -5), we apply two transformations.

The first transformation (x - 2, y) is defined as shifting the x-coordinate of each point left by 2 units, while keeping the y-coordinate the same.

This results in new points P' = (1, -2) and S' = (2, -5).

The second transformation involves reflecting the new points across the x-axis, which changes the sign of their y-coordinates.

The resulting points are P'' = (1, 2) and S'' = (2, 5).

In this context, we are given the coordinates of point A as (-2, -5).

This implies that if we scale down the original coordinates by a factor of 1/2, we get the new coordinates of point A, which become (-1, -2.5).

Therefore, the coordinates of point A' are (-1, -2.5).

Answer:

To calculate the probability that the winner of the gift certificate bought a printer from Super Electronics, we need to use the total number of customers who participated in the survey as the denominator and the number of customers who bought printers as the numerator.

The total number of customers who participated in the survey is:

Total Customers = Number of Customers who bought Laptops + Number of Customers who bought Desktops + Number of Customers who bought Printers

Total Customers = 88 + 52 + 64

Total Customers = 204

The number of customers who bought printers is 64.

Therefore, the probability that the winner of the gift certificate bought a printer from Super Electronics is:

P(Bought a Printer) = Number of Customers who bought Printers / Total Customers

P(Bought a Printer) = 64 / 204

P(Bought a Printer) = 0.3137 (rounded to 4 decimal places)

So, the probability that the winner of the gift certificate bought a printer from Super Electronics is 0.3137 or approximately 31.37%.
