Answer: BMI stands for Body Mass Index, and it is a simple calculation that can help you determine whether your weight is healthy for your height. The BMI formula is as follows:

BMI = weight in kilograms / (height in meters)²

To use the BMI formula, follow these steps:

Measure your weight in kilograms. If you know your weight in pounds, you can convert it to kilograms by dividing by 2.205.

Measure your height in meters. If you know your height in feet and inches, you can convert it to meters by multiplying your height in inches by 0.0254. For example, if you are 5 feet 6 inches tall, you would calculate your height in meters as follows: (5 x 12) + 6 = 66 inches, and 66 x 0.0254 = 1.68 meters.

Once you have your weight in kilograms and your height in meters, use the BMI formula to calculate your BMI score. For example, if you weigh 70 kilograms and your height is 1.75 meters, your BMI would be calculated as follows:

BMI = 70 / (1.75)²

BMI = 70 / 3.06

BMI = 22.9

Once you have your BMI score, you can use it to determine whether your weight is within a healthy range for your height. The World Health Organization (WHO) uses the following categories to classify BMI scores:

Underweight: less than 18.5

Normal weight: 18.5 to 24.9

Overweight: 25 to 29.9

Obesity: 30 or higher

Note that BMI is not always an accurate indicator of health, as it does not take into account factors such as muscle mass and body composition. It is best used as a general guideline, and if you have concerns about your weight or overall health, it's a good idea to consult with a healthcare professional.

T(U) is a subspace of W Since V is a subspace of U, the zero vector of V, 0, is in U. As T is linear, \(T(0) = 0_w\) , where \(0_w\)  is the zero vector of W. Therefore, \(0_{w}\) is in T(U).

It can be proved  Since U is a subspace of V, the zero vector of V, 0y, is in U. Since T is linear, \(T(0_{y}) = 0_{w}\) , where \(0_{w}\) is the zero vector of W. So\(0_{w}\)  is in T(U).

To show that T(U) is a subspace of W, we also need to show that T(U) is closed under vector addition and scalar multiplication. Let u1, u2 be vectors in U, and let c be a scalar. Then we have: \(T(u1 + u2) = T(u1) + T(u2)\)  (since T is linear)

\(T(cu1) = cT(u1)\)  (since T is linear)

Since U is a subspace of V, we have \(u1 + u2\) and \(cu1\)  are also in U. Therefore, \(T(u1 + u2)\)  and \(T(cu1)\)  are both in T(U), which shows that T(U) is closed under vector addition and scalar multiplication.

Thus, T(U) is a subspace of W.

In order to get a final average of 80, you need to score a 90 on the final exam.

To find the final grade you need to get on the final exam, we need to set up an equation based on the information provided. Let's call the final exam score "x".

The final average, which needs to be 80, is equal to two thirds of the average of the exams (75) plus one third of the final exam score (x).

So, we have: 80 = (2/3) * 75 + (1/3) * x

Expanding the right side of the equation, we get: 80 = 50 + x/3

Subtracting 50 from both sides, we get: 30 = x/3

Multiplying both sides by 3, we get: 90 = x

So, in order to get a final average of 80, you need to score a 90 on the final exam.  in order to get a final average of 80, you need to score a 90 on the final exam.

To multiply the algebraic expression x(9x - 9), we can use the special product formula (a-b)(a+b) = a^2 - b^2.

Using the formula, we can see that 9x - 9 can be written as (3x - 3)(3x + 3), where a = 3x and b = 3. Therefore, x(9x - 9) can be written as x(3x - 3)(3x + 3). Multiplying the expression, we get 3x^2(x - 1)(3x + 3). We can simplify this further by factoring out 3x^2 from the last two terms, which gives us the final answer of 3x^2(x - 1)(3x + 3) = 9x^4 - 27x^2.

To multiply the algebraic expression x(9x - 9), we used the special product formula (a-b)(a+b) = a^2 - b^2. By applying the formula, we simplified the expression to 3x^2(x - 1)(3x + 3), which we further simplified to the final answer of 9x^4 - 27x^2.

Number of students need to be sampled = 610

A study to determine the true average number of alcoholic drinks consumed by Greek students is conducted.

Standard Deviation, σ = 6.3

Margin Error of population mean, E = 0.5

Probability = 95% = 0.95

The p-value corresponding to 0.95 probability = (1+0.95)/2 = 0.975

The z-score corresponding to this p-value = 1.96 [from the z-tables]

Now, The margin error, E = zσ/√n, where n is the sample size

⇒ n = (zσ/E)²

⇒ n = (1.96 x 6.3/0.5)²

⇒ n ≈ 610

In mathematics, SAS stands for 'Side-Angle-Side' which is a criterion used to determine congruence (equality in size and shape) between two triangles.

The SAS criterion states that if two triangles have two sides that are proportional in length

and the included angles between those sides are congruent, then the two triangles are congruent.

To understand how SAS works,

Side,

This refers to a specific side of a triangle.

In the SAS criterion, we compare the lengths of the sides of two triangles to determine if they are proportional.

Angle

This refers to a specific angle within a triangle.

In the SAS criterion, compare the angles formed by the corresponding sides of the two triangles to determine if they are congruent.

Side-Angle-Side

This combination of a side, an angle, and another side is what we compare between two triangles.

If the two triangles have the same proportions for the corresponding sides and the same measures for the included angles,

they are considered congruent.

To illustrate this, let's consider an example

Suppose we have two triangles, triangle ABC and triangle DEF.

If side AB is proportional in length to side DE, angle BAC is congruent to angle EDF, and side BC is proportional in length to side EF,

then conclude that triangle ABC is congruent to triangle DEF using the SAS criterion.

By applying the SAS criterion,

mathematicians can determine whether two triangles are congruent without relying on other criteria such as Side-Side-Side (SSS),

Angle-Angle-Side (AAS), or Side-Angle-Angle (SAA).

Congruence is a fundamental concept in geometry and plays a significant role in various geometric proofs and constructions.

Given:

The coordinates of ∆ABC are A(-3, 2), B(5, 8) & C(11, 0).

To find:

The type of the given triangle.

Solution:

Distance formula:

\(D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

Using the distance formula, we get

\(AB=\sqrt{(5-(-3))^2+(8-2)^2}\)

\(AB=\sqrt{(8)^2+(6)^2}\)

\(AB=\sqrt{64+36}\)

\(AB=\sqrt{100}\)

\(AB=10\)

Similarly,

\(BC=\sqrt{(11-5)^2+(0-8)^2}\)

\(BC=\sqrt{(6)^2+(8)^2}\)

\(BC=\sqrt{36+64}\)

\(BC=\sqrt{100}\)

\(BC=10\)

And,

\(AC=\sqrt{(11-(-3))^2+(0-2)^2}\)

\(AC=\sqrt{(14)^2+(-2)^2}\)

\(AC=\sqrt{196+4}\)

\(AC=\sqrt{200}\)

\(AC=10\sqrt{2}\)

Two sides of the triangle are equal, i.e., \(AB=BC\). So, the triangle is an isosceles triangle.

Sum of square of two smaller side is

\(AB^2+BC^2=10^2+10^2\)

\(AB^2+BC^2=100+100\)

\(AB^2+BC^2=200\)

\(AB^2+BC^2=AC^2\)

Using the Pythagoras theorem, we can say that the given triangle is a right triangle.

Therefore, the correct options are B and F.

The slope of the tangent at the point (3, 3, 1) is -27/7. Therefore, the equation of the tangent is 27x + 7y = 90.

The given curve is x³/2 + y³/2 = 4. We have to find the equation of the tangent to this curve at the point (3, 3, 1).

Let y = f(x), then x³/2 + y³/2 = 4 becomes

f(x) = (4 - x³/2)³/2 = 2(8 - x³)³/2.

The slope of the tangent at the point (3, 3, 1) is the value of f'(3).

We know that the derivative of f(x) is given by

f'(x) = -3x²/2 (8 - x³)-1/2 and

f'(3) = -27/7.

Therefore, the slope of the tangent at (3, 3, 1) is -27/7.

Using the point-slope form of the equation of the line, we get the equation of the tangent as  :

y - 3 = (-27/7)(x - 3)

27x + 7y = 90

Therefore, the slope of the tangent at the point (3, 3, 1) is -27/7. Therefore, the equation of the tangent is 27x + 7y = 90.
