Triangles can be classified based on their angles (as acute, right, or obtuse triangles) or based on their sides (as equilateral, isosceles, or scalene triangles). The study of triangles is fundamental in many areas of mathematics and physics and is also important in practical applications such as engineering, architecture, and surveying.

by the question.

To find the area of the shaded region, we first need to find the area of the entire rectangle. The area of a rectangle is given by the formula: length x width.

The length of the rectangle is 12 meters, and the width is 8 meters, so the area of the entire rectangle is:

12m x 8m = 96 square meters

Next, we need to find the area of the triangle that is not shaded. The base of the triangle is 6 meters, and the height is 8 meters. The area of a triangle is given by the formula: 1/2 x base x height.

1/2 x 6m x 8m = 24 square meters

Finally, we can find the area of the shaded region by subtracting the area of the triangle from the area of the entire rectangle:

The total amount of water supplied per hour inside a circle of radius 14 is approximately79.90 ft^3 per hour, and the total amount of water that goes through the sprinkler per hour is approximately  2π ft^3 per hour. As R approaches infinity, the total amount of water supplied per hour approaches  2 ft^3 per hour.

To find the total amount of water supplied per hour inside of a circle of radius 14, we need to integrate the function e^(-r) over the region of the circle total amount of water = ∫∫ e^(-r) dA

where the integration is over the circular region of radius 14, and dA is the differential area element.

Using polar coordinates, we can write dA = r dr dθ, and the limits of integration are 0 ≤ r ≤ 14 and 0 ≤ θ ≤ 2π. Substituting these values, we get:

total amount of water = ∫(0 to 2π) ∫(0 to 14) e^(-r) r dr dθ

Integrating with respect to r first, we get:

total amount of water = ∫(0 to 2π) [-e^(-r)](0 to 14) dθ

total amount of water = ∫(0 to 2π) (1 - e^(-14)) dθ

total amount of water = (1 - e^(-14)) ∫(0 to 2π) dθ

total amount of water = 2π(1 - e^(-14))

Thus, the total amount of water supplied per hour inside of a circle of radius 14 is approximately 79.90 ft^3 per hour.

To find the total amount of water that goes through the sprinkler per hour, we need to integrate the function e^(-r) over the entire plane:

total amount of water = ∫∫ e^(-r) dA

where the integration is over the entire plane, and dA is the differential area element.

Using polar coordinates, we can write dA = r dr dθ, and the limits of integration are 0 ≤ r ≤ ∞ and 0 ≤ θ ≤ 2π. Substituting these values, we get:

total amount of water = ∫(0 to 2π) ∫(0 to ∞) e^(-r) r dr dθ

Integrating with respect to r first, we get:

total amount of water = ∫(0 to 2π) [-e^(-r)](0 to ∞) dθ

total amount of water = ∫(0 to 2π) (1) dθ

total amount of water = 2π

Thus, the total amount of water that goes through the sprinkler per hour is exactly 2π ft^3 per hour.

To calculate the total amount of water supplied per hour inside a circle of radius R, then let R → ∞, we can use the result from part B and multiply it by the ratio of the areas of the two circles:

total amount of water = (total amount of water inside circle of radius R) × (area of circle of radius R)/(area of entire plane)

total amount of water = (2πR^2(1-e^(-R))) / (πR^2)

total amount of water = 2(1-e^(-R))

Now we can let R → ∞:

total amount of water = 2

Thus, the total amount of water supplied per hour inside a circle of infinite radius is exactly 2 ft^3 per hour.

Para resolver este problema, primero tenemos que multiplicar las fracciones:

3/5 x 4/7 = 12/35

Luego, encontramos cuántas docenas son 12/35 de 420 docenas:

(12/35) x 420 = 144

Así que 3/5 de 4/7 de 420 docenas (que es equivalente a 12/35 de 420 docenas) representa 144 docenas de huevos.

Para encontrar el número total de huevos, multiplicamos 144 docenas por 12 huevos por docena:

144 x 12 = 1,728

Por lo tanto, 3/5 de 4/7 de 420 docenas representa 1,728 huevos.

The rate at which the height of the water is increasing when water is being pumped in at a rate of 2/3 m/s and the water is 9m deep is 0.667 m/s.

We can start by using the formula for the volume of a square pyramid to find the volume of water in the tank. Let V be the volume of water in the tank and h be the height of the water.

V = (s² [h])/3

We know that the base of the pyramid is 3m by 3m, so s = 3. Also, the height of the pyramid is 16m, so we have:

V = (3² [h])/3

V = 3h

Now, we can find the rate of change of the volume with respect to time:

dV/dt = 3 [dh/dt]

We know that water is being pumped in at a rate of 2/3 m/s, so dh/dt = 2/3. We want to find how fast the height increases when the water is 9m deep, so h = 9. Substituting these values, we get:

dV/dt = 3 [dh/dt]

dV/dt = 3 [2/3]

dV/dt = 2

Therefore, the rate at which the volume of water is increasing is 2 cubic meters per second. To find the rate at which the height of the water is increasing, we need to solve for dh/dt:

dV/dt = 3 [dh/dt]

2 = 3 * dh/dt

dh/dt = 2/3

So the height of the water is increasing at a rate of 2/3 m/s when the water is 9m deep. Rounded to 3 decimal places, the answer is 0.667 m/s.

Triangle XYZ will be translated to X'Y'Z' and the coordinates of Z' are (6,7).

A transformation known as a translation involves shifting each point in an image uniformly in one direction. It is also a type of transformation where every point in a figure is moved by the same amount in the same direction, producing a new figure that is identical to the original.

From the graph,

The coordinates of X are (7, 11)

The coordinates of Y are (10, 14)

The coordinates of Z are (8, 7)

When triangle XYZ is translated to X'Y'Z', the X-coordinate is given as (5, 11), which means the X-coordinate shifts left 2 points, so we need to subtract 2 from X-coordinate and keep Y-coordinate as it is.

Therefore the coordinate of the triangle X'Y'Z' are as follows,

The coordinates of X' are (7-2, 11) = (5,11)

The coordinates of Y' are (10-2, 14) = (8, 14)

The coordinates of Z' are (8-2, 7) = (6, 7)

We cannot determine the exact number of votes for Tim or Selena without additional information. However, we can determine the fraction of the whole class that voted for each candidate based on the given information.

If only one third of the students cast votes, that means that two thirds did not vote. Therefore, the fraction of the whole class that voted for Tim and Selena is each equal to one third of the total number of students.

To calculate these fractions, we can use the following formula:

Fraction of class = Number of students who voted / Total number of students

Let's assume that there are N students in the class. Then, the number of students who voted for Tim is (1/3)N, and the number of students who voted for Selena is also (1/3)N.

So, the fraction of the whole class that voted for Tim is:

(1/3)N / N = 1/3

Similarly, the fraction of the whole class that voted for Selena is also 1/3.

Since we don't know the exact number of votes for each candidate, we cannot determine who received more votes.

The value of T(v), express v as linear combination in the basis B and the matrix representation of T obtain is T(v) = [4, -4].

To find T(v), we need to express v as a linear combination of the basis vectors of R^3 with respect to B:

v = (-1)[0] + (-1)[0] + (1)[1]

This means that the coordinate vector of v with respect to B is [-1, -1, 1].

To find the matrix representation of T with respect to the standard bases of R^3 and R^2, we can apply T to each of the basis vectors:

T([1, 0, 0]) = [1, 3]

T([0, 1, 0]) = [-1, 1]

T([0, 0, 1]) = [2, -2]

We can arrange the results in a matrix:

[1 -1 2]

[3 1 -2]

The matrix [1 -1 2; 3 1 -2] represents T with respect to the standard bases of R^3 and R^2.

To find T(v), we can multiply the matrix representation of T with the coordinate vector of v with respect to B:

T(v) = [1 -1 2; 3 1 -2] * [-1; -1; 1] = [4; -4]

Therefore, the man finished his trip at 8:40 pm with total travelling time of 10 2/3 hours.

In mathematics, a fraction is a representation of a part of a whole or a ratio between two quantities. It consists of two numbers, a numerator and a denominator, separated by a horizontal line, also called a fraction bar or a vinculum. The numerator represents the number of equal parts being considered, while the denominator represents the total number of parts that make up the whole.

Here,

We can solve this problem using the formula:

distance = rate x time

Let's start by finding the time it took for the man to travel 450 kilometers at an average speed of 50 kilometers per hour:

time = distance / rate

time = 450 km / 50 km/h

time = 9 hours

So the man spent 9 hours travelling. However, he also took two breaks: a 40-minute rest and a 1-hour lunch break. We need to convert these times to hours to include them in our calculation.

40 minutes is equal to 40/60 = 2/3 hours, and 1 hour is simply 1 hour. So the total time the man spent travelling, including the breaks, is:

total time = 9 hours + 2/3 hours + 1 hour

total time = 10 2/3 hours

To find the finishing time, we add the total time to the starting time of 10 am:

The expression 61+x when x = 18 evaluates to 79.

Expression is a combination of numbers, symbols and operators that represent a mathematical quantity or operation.

To find the value of the expression, we must first substitute 18 in for x.  To evaluate this expression, we must add 61 and 18. 61+18 = 79. Therefore, the expression 61+x when x = 18 evaluates to 79.

To verify the answer, we can use the distributive property of multiplication to expand the expression. 61+x is equivalent to 61+18, which can be written as

61+18 = 61+1*18.

We can now distribute the 1 to the 18,
