What is pythagoras theorem?

The Pythagorean Theorem, also known as the Pythagoras Theorem, is one of the most fundamental theorems in mathematics and it defines the relationship between the three sides of a right-angled triangle. In a right-angled triangle, one of the angles is  90∘, and the side that is opposite to that  90∘  (right) angle is known as the hypotenuse. The other two sides that are adjacent to the right angle are called the legs of the triangle.

It is given that  an 11.0 m ladder leans against the side of a building and ladder reaches up to the bottom of a window 9.5 m above the ground.

Diagram of this problem will be right angled triangle having hypotenuse 11 m and perpendicular 9,5 m

Using pythagoras theorem,

\(H^2=P^2+B^2\)

\((11)^2=(9.5)^2+B^2\)

121 = 90.25 + \(B^2\)

\(B^2\) = 121 - 90.25 = 30.75

B = \(\sqrt{30.75}\) = 5.6 m

Therefore, Base of the ladder is 5.6 m far away from the wall.

Setting x1 to zero in the equation 2x1 + 1x2 = 30 results in the value of x2 being 30.

The given equation is 2x1 + 1x2 = 30, where x1 and x2 represent variables. To find the value of x2 when x1 is set to zero, we substitute x1 with zero in the equation.

By replacing x1 with zero, we have 2(0) + 1x2 = 30. Simplifying further, we get 0 + 1x2 = 30, which simplifies to x2 = 30.

When x1 is set to zero, the equation reduces to a simple linear equation of the form 1x2 = 30. Therefore, the value of x2 in this scenario is 30.

Setting x1 to zero effectively eliminates the contribution of x1 in the equation, allowing us to focus solely on the value of x2. In this case, when x1 is removed from the equation, x2 becomes the sole variable responsible for fulfilling the equation's requirement of equaling 30. Thus, x2 is determined to be 30.

By using empirical rule, 99.7% of the customers have to wait between 36 minutes and 48 minutes.

To determine the percentage of customers who have to wait between 36 minutes and 48 minutes, we can use the empirical rule (also known as the 68-95-99.7 rule) for a normal distribution.

According to the empirical rule:

In this case, the mean is 42 minutes and the standard deviation is 2 minutes.

To find the percentage of customers who have to wait between 36 minutes and 48 minutes, we can calculate the z-scores for these values and then determine the percentage of data within that range.

The z-score is calculated using the formula:

z = (x - mean) / standard deviation

For 36 minutes:

z₁ = (36 - 42) / 2 = -3

For 48 minutes:

z₂ = (48 - 42) / 2 = 3

Since the z-scores fall within the range of -3 to 3, which is within three standard deviations of the mean, we can conclude that approximately 99.7% of the customers will have to wait between 36 minutes and 48 minutes.

The given system of linear equations consists of four equations with four variables: x, y, z, and w. To solve the system, we can use various methods, such as Gaussian elimination or matrix operations.

By performing row operations, we can reduce the system to its row-echelon form or solve it directly to find the values of x, y, z, and w. We will solve the system of linear equations using the method of Gaussian elimination. The augmented matrix representation of the system is:

[1 1 2 -1 | -2]

[0 3 1 2 | 2]

[1 1 0 3 | 2]

[-3 0 1 2 | 5]

First, we'll perform row operations to transform the matrix into the row-echelon form:

R2 = R2 - 3R1

R3 = R3 - R1

R4 = R4 + 3R1

The resulting matrix after these operations is:

[1 1 2 -1 | -2]

[0 0 -5 5 | 8]

[0 0 -2 4 | 4]

[0 3 1 2 | 5]

Next, we'll perform additional row operations to further simplify the matrix:

R4 = R4 - 3R2

The matrix now becomes:

[1 1 2 -1 | -2]

[0 0 -5 5 | 8]

[0 0 -2 4 | 4]

[0 3 1 2 | -19]

Finally, we'll perform the last row operation:

R3 = R3 + 2R2

The matrix is now in row-echelon form:

[1 1 2 -1 | -2]

[0 0 -5 5 | 8]

[0 0 0 14 | 20]

[0 3 1 2 | -19]

From this row-echelon form, we can solve for the variables. Starting from the bottom row, we obtain:

3w + z + 2w = -19, which simplifies to 5w + z = -19.

Next, we have 0x + 0y - 5z + 5w = 8, which simplifies to -5z + 5w = 8.

Lastly, x + y + 2z - w = -2.

At this point, we have three equations with three variables: x, y, and z. By solving this simplified system, we can find the values of x, y, and z.

The height in centimeters of the platform is 48.9 centimeters.

To find the height in of the platform formed by spreading the dirt dug out of a well is;

Step 1: Calculate the volume of the well.
The well is in the shape of a cylinder, so we can use the formula for the volume of a cylinder: V = πr^2h, where V is the volume, r is the radius, and h is the height (depth in this case). The diameter is 2.8 meters, so the radius is half of that, which is 1.4 meters.

V = π(1.4^2)(15)
V ≈ 92.4 m^3

Step 2: Calculate the volume of the platform.
Since the volume of the dirt in the well is equal to the volume of the dirt used to form the platform, we can set up an equation to find the height (h) of the platform.

Volume of the platform = Length x Width x Height
92.4 = 31.5 x 6 x h

Step 3: Solve for the height (h).
92.4 = 189h
h ≈ 0.489 meters

Step 4: Convert the height to centimeters and round to the nearest tenth.
0.489 meters = 48.9 centimeters

So, the height of the platform is approximately 48.9 centimeters.

A $100 bill and a dime differ by a magnitude of 3.

Orders of magnitude can be used in order to define large quantities efficiently and more easily. A dime is a currency used in the US that is equivalent to 0.10 dollars.

So we can represent a dime as 10-¹ of a dollar

and we can write 100 dollars as 10² of a dollar.

Therefore the difference in the order of magnitude of 100 dollars and a dime would be the difference between the powers or exponents of those two quantities,
