The length of side AB is about 5.87 units.

The triangle ABC is a right angle triangle. A right angle triangle is a triangle that has one of its angles as 90 degrees.

Therefore, let's find the length AB in the right triangle.

Using trigonometric ratios,

cos 33 = adjacent / hypotenuse

Therefore,

Adjacent side = AB

hypotenuse side = 7 units

cos 33° = AB / 7

cross multiply

AB = 7 cos 33

AB = 7 × 0.83867056794

AB = 5.87069397562

AB = 5.87 units

Answer:

The answer to your question is given below

Step-by-step explanation:

Let 'a' and 'b' be the length of the first two sides of the triangle and let 'c' be the longest length of the triangle.

The following data were obtained from the question:

Length of a = 17 m

Length of b = 144 m

Length of c = 145

For the triangle to be a right-angled triangle, then it must certify the pythagoras theory which states that the square of the two sides in a right-angled triangle is equal to the square of the longest side.

Thus, we can prove that the triangle is a right-angled triangle as illustrated below:

a² + b² = c²

Length of a = 17 m

Length of b = 144 m

Length of c = 145

17² + 144² = 145²

289 + 20736 = 21025

21025 = 21025

From the above illustration, we can see clearly that the square of two sides of the triangle is equal to the square of the longest side. Therefore, the triangle is a right-angled triangle.

The correct answer is that the data set {3, 7, 4} is represented in the given histogram.(option-a)

The given histogram represents the number of children in each age group who need to travel to school. Since the histogram has only three bars, we can conclude that there are only three age groups.

The first bar represents children aged 5-10, of which there are 3. The second bar represents children aged 11-13, of which there are 7. The third bar represents children aged 14-18, of which there are 4.

Therefore, the data set that is represented in the histogram is:

{3, 7, 4}

None of the other data sets given match the values in the histogram. The first data set has duplicate values and is not sorted by age group. The second data set includes ages that are not represented in the histogram. The third data set has values for ages 6, 11, 12, 13, 14, 15, 17, and 18, but the histogram does not have bars for all those ages. (option-a)

The net monthly income from the building is

Rs 346.33

Percent simply means "per hundred" and the symbol used to express percentage is %. One percent (or 1%) is one hundredth of the total or whole and is therefore calculated by dividing the total or whole number by 100. Example: 1% of 250 = (1 ÷ 100) x 250 = 2.5.

Therefore The yearly income = Rs 5800

10% = 5800 × 10/100 = Rs 580

The remaining rent = 5800-580 = Rs 5320

10½% = 21/200 × 5320

= 558.6

7¼ % = 29/400 × 5320

= 385.7

2¼ = 9/400 × 5320

= 119.7

total tax = 119.7 + 385.7 + 558.6 +580

= Rs 1644

Income left = 5800-1644

= 4156

therefore monthly net income = 4156/12

= Rs 346.33

The missing segment length is option (c) 25.

Angle bisector theorem states that if a line segment is drawn from a vertex of a triangle to the opposite side such that it bisects the angle, then the two parts of the opposite side which are divided by the line segment is proportional to the other two sides of the triangle.

Here given a triangle ABC.

Angle B is bisected with the line segment BD.

Then by Angle Bisector theorem,

AD / DC = AB / BC

Given side lengths,

AD = 12

DC = 32 - 12 = 20

AB = 15

BC = y

Substituting all the points,

12 / 20 = 15 / y

Cross multiplying,

12y = 20 × 15

y = 25

Hence the missing side length is 25.

1. The slopes of perpendicular lines are  a negative reciprocal

2. Parallel lines have the same slope.

3. The shortest distance from any point to a line is a straight line

The slope of two perpendicular lines is such that the slope of one line is equal to the reciprocal of the negative slope of the other.

if two lines of slope m and m' are perpendicular their slopes is written as

m = -1/m'

Parallel lines grow vertically and flow horizontally at the same rate. they have the same slope, they never cross.

An orthonormal set is a set of orthogonal unit vectors.

Normalization is the process of making unit vectors.

A set of vectors in which each vector is orthogonal to every other vector in the set is called an orthogonal set of vectors.

Two vectors are orthogonal when their dot product equals zero.

An orthonormal set is one in which each vector has length 1 and is orthogonal.

The process of creating a vector of length 1 in the same direction of the original vector is called "normalization".

An orthonormal set of vectors that is a basis of a vector space is quite useful. We can use the Gram-Schmidt process to transform a basis of a vector space (which may not be orthogonal) into an orthonormal basis.

To normalize vectors to produce an orthonormal set of vectors, we calculate the length of the vector and divide the vector by its length, to obtain a unit vector.

Since the question asked about "how to normalize vectors to produce an orthonormal set" that implies that the vectors already form an orthogonal set.

Let x be the fourth number.

We know that the sum of the four numbers is 20500:

2341.578 + 10690 + x + 2341.578 = 20500

Simplifying and solving for x:

x = 20500 - 2341.578 - 10690 - 2341.578

This question requires the application of the appropriate trigonometric function to solve it. So that the appropriate answer is; the shooter was on the second floor window = 14 feet from the grou i.e option B.

Let the height from the  the ground to tip of the gun be represented by y. Then applying the appropriate trigonometric function, we have:

Tan θ = \(\frac{opposite}{adjacent}\)

So that;

Tan 11 = \(\frac{y}{78}\)

⇒ y = Tan 11 x 78

      = 0.1943 x 78

y = 15.1554

y = 15 feet

Therefore, considering some other factors as regards the woman's ankle to the ground and the gun's tip in relation to the floor of the second floor, then we can say that the shooter was on the second floor window = 14 feet from the ground.

The required answer is option B.

Step-by-step explanation:

Consider finding points on the graph using the equation.

x = 0 : f(0) = \(0.5^{0}\) + 4 = 1 + 4 = 5 ← y- intercept

Since y- intercept is 5, this excludes the lower 2 graphs, which have y- intercepts of 1

x = 1 : f(1) = \(0.5^{1}\) + 4 = 0.5 + 4 = 4.5 ⇒ (1, 4.5 )

x = - 1 : f(- 1) = \(0.5^{-1}\) + 4 = \(\frac{1}{0.5}\) + 4 = 2 + 4 = 6 ⇒ (1, 6 )

The percentile of 6.2 in the given data set is 40%.

To determine the percentile of 6.2 in the given data set, we can use the following steps:

Arrange the data set in ascending order:

4.2, 4.6, 5.1, 6.2, 6.3, 6.6, 6.7, 6.8, 7.1, 7.2

Count the number of data points that are less than or equal to 6.2. In this case, there are 4 data points that satisfy this condition: 4.2, 4.6, 5.1, and 6.2.

Calculate the percentile using the formula:

Percentile = (Number of data points less than or equal to the given value / Total number of data points) × 100

In this case, the percentile of 6.2 can be calculated as:

Percentile = (4 / 10) × 100 = 40%

The percentile of 6.2 in the sample data set is therefore 40%.
