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.

Answer:

56.54 inches

Step-by-step explanation:

If the radius is 3 inches, to find the area of the circle your equation would be A = (pi) x r^2

Your equation would look like this:

A = (pi) x 3^2

A = 28.27

Now to get the volume of the pie, you would multiply 28.27 x 2 which gives you an answer of 56.54 inches.

Part a: ∠ABE and ∠DBE share a ray EBC as EBC is a straight line.

Part b: ∠ABE and ∠DBE are opposite to each other. Thus, the are termed as the  vertical angles.

Angles that are opposing each other whenever two lines connect are known as vertical angles. According to the vertical angles theorem, vertical angles are consistently congruent.

When two lines in geometry connect, four angles are created. Vertical angles are those that are not next to one another or that are opposing one another. Since they always utilize the same measure, vertical angles are unique.

Postulate for Angle Addition: When two neighbouring angles combine to make a straight line, its result is 180°.

The given angles:

∠ABE = ∠DBE (vertical angles)

Part a: ∠ABE and ∠DBE share a ray EBC .

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, T(v) = [4, -4].

It will take 2.2 hours for the two trains to meet.

We can find the time taken by the two trains to meet by using the formula,

large Time=Distance/Speed

Let's consider the time taken by the two trains to meet be "t".The distance between two trains = 418 miles.

Now, the first train is traveling at a speed of 85 mph and the second train is traveling at a speed of 105 mph.

Let's calculate the distance covered by both the trains in time "t".The distance covered by the first train in time "t"=85t.

The distance covered by the second train in time "t"=105t.

So, the total distance covered by both the trains in time "t" is,

Distance covered = 85t+105t=190t.

But we know the distance between the two trains is 418 miles.

Therefore,190t = 418

Now, solve for "t"t = 418/190t = 2.2 hours

Therefore, the two trains will meet in 2.2 hours.

The value of c is equal to 4.

The value of d is equal to 0.

In Geometry, a reflection across or over the x-axis is modeled and represented by the following transformation rule (x, y) → (x, -y). Therefore, a reflection across or over the x-axis would maintain the same x-value while the sign of the y-value would change from negative to positive or positive to negative as the case may be.

One of the vertices of triangle A is given by:

(x, y)                 →         (x, -y)

A (-1, -1)            →         A' (-1, -(-1) = (-1, 1)

When a translation is applied to triangle A', one of the corresponding or resulting vertices of triangle B is given by:

B (3, 1)

A' (-1 + c, 1 + d) → B (3, 1)

The average rate of change from year 1 to year 10 is: (150 - 69)/9 = 9 based on the given function.

The amount of maize the farmer's land is yielding in pounds per acre over x years is represented by the function f(x)=[tex]-x^2+20x+50[/tex].

We must compute the change in f(x) for the range [1,10] and divide by the interval's length to determine the average rate of change from year 1 to year 10.

f(1) = [tex]-(1)^2[/tex] + 20(1) + 50 = 69

f(10) = [tex]-(10)^2[/tex] + 20(10) + 50 = 150

Hence, the change in f(x) throughout the range [1,10] is as follows:

f(10) - f(1) = 150 - 69 = 81

And the interval [1,10] has the following length:

10 - 1 = 9

Thus, from year one to year ten, the average rate of change is:

(150 - 69)/9 = 9

By interpreting the average rate of change, we can conclude that from year 1 to year 10, the farmer's land's yield of maize per acre is growing at a pace of 9 pounds each year. This indicates that, on average, throughout the course of these ten years, the farmer can anticipate harvesting 9 extra pounds of maize per acre.

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 surface area of the triangular prism is 891 square inches, calculated by finding the area of each face (two triangular and three rectangular) and adding them up.

To find the surface area of the triangular prism, we need to find the area of each face and add them up.

The triangular prism has two identical triangular faces and three rectangular faces. The triangular faces have base 9 inches, height 12 inches, and hypotenuse 15 inches. The area of each triangular face can be found using the formula for the area of a triangle:

Formula for area of each triangular face = (1/2) x base x height

= (1/2) x 9 x 12

= 54 square inches

The prism also has three rectangular faces, each with length equal to the base of the triangle (9 inches) and width equal to the height of the prism (29 inches). The area of each rectangular face can be found using the formula for the area of a rectangle:

Area of each rectangular face = length x width

= 9 x 29

= 261 square inches

Hence, the triangular prism's total surface area is:

Total surface area = 2(Area of each triangular face) + 3(Area of each rectangular face)

= 2(54) + 3(261)

= 108 + 783

= 891 square inches

Therefore, the surface area of the triangular prism is 891 square inches.

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:

finishing time = 10 am + 10 2/3 hours
