find the direction cosines of the line which is perpendicular to the lines whose direction cosines are proportional to 3,-2,3 and 1,-2,-1

Answers

Answer 1

The direction cosines of the line are:

x = 8 / √116

y = 6 / √116

z = -4 / √116

What are direction ratios?

Direction ratio helps in knowing the components of a line or a vector with reference to the three-axis, the x-axis, y-axis, and z-axis respectively.

We have,

Let the direction ratio of the line be (x, y, z)

The line is perpendicular to the lines whose direction cosines are proportional to 3,-2,3 and 1,-2,-1.

Now we have,

3x - 2y + 3z = 0 _____(1)

x - 2y - z = 0 _____(2)

We will find the value of x, y, and z using cross product.

x / 2 + 6 = y / 3 + 3 = z / -6 + 2

x / 8 = y / 6 = z / -4

We get,

x = 8

y = 6

z = -4

The direction cosines of the line are:

x = 8 / √8² + 6² + (-4)²

x = 8 / √64 + 36 + 16

x = 8 / √116

y = 6 / √116

z = -4 / √116

Thus the direction cosines of the line are:

x = 8 / √116

y = 6 / √116

z = -4 / √116

b. Median=3 and mean = 3.5
c. Median = 3.5 and mean = 3

IMAGE ABOVE

Answers

The correct statements regarding the mean and the median of the distribution are given as follows:

b. Median = 3 and Mean = 3.5.

What are the mean and the median of a distribution?

The mean of a data-set is given by the sum of all values in the data-set, divided by the cardinality of the data-set, which is the number of values in the data-set.The median of a data-set is given by the middle value of the data-set, which is the value for which 50% of the data-set is less than and 50% of the data-set is greater than.

From the frequency table, we have that:

5 observations have a value of 1.7 observations have a value of 2.8 observations have a value of 3.6 observations have a value of 4.5 observations have a value of 5.3 observations have a value of 6.1 observations have a value of 7.1 observations have a value of 10.

The number of values in the data-set is:

5 + 7 + 8 + 6 + 5 + 3 + 1 + 1 = 36.

Hence the mean is given by:

M = (5 x 1 + 7 x 2 + 8 x 3 + 6 x 4 + 5 x 5 + 3 x 6 + 1 x 7 + 1 x 10)/36 = 3.5.

The median will be the 36/2 = 18th value, which is of 3.

Hence the correct statement is:

b. Median = 3 and Mean = 3.5.

Step-by-step explanation:

Find other root. Use x as a substitute.

[tex]x = 2 + \sqrt{3}\\x - 2 = \sqrt{3}\\\left(x - 2\right)^2 = 3\\x^2 = 4 - 2 \times x \times 2 = 3\\x^2 - 4x + 1 = 0[/tex]

Now, we must use the quadratic formula to find the rest of the solution.

[tex]x = \frac{-b\pm \sqrt{b^2-4ac} }{2a}\\x = \frac{4\pm \sqrt{\left(-4\right)^2-4 \times 1 \times 1} }{2}\\\frac{4 \pm \sqrt{12} }{2} = 2 \pm 3[/tex]

If one root of this polynomial [root] is 2 - √3, the other will be 2 + √3. Inversing that rule, the answer is 2 - √3.

Examples of the given theorem are [tex]\frac{2}{4} \ \& \ \frac{3}{6}[/tex] , [tex]\frac{4}{16} \ \& \ \frac{8}{32}[/tex]  and so on .

Equivalent fractions can be defined as fractions that have different numerators and denominators but represent the same value. Two or more fractions are said to be equivalent if they simplify to the same fraction. Equivalent fractions are fractions that have the same value regardless of the numerator and denominator.For example, the equivalent fractions of 1/5 are 5/25, 6/30, and 4/20, which on simplification, result in the same fraction, that is, 1/5.

The number of honeybees which it will take to make the required 2 tablespoons of honey as required in the task content is; 72.

How many honeybees will it take to make 2 tablespoons of honey?

It follows from the conversion factor given in the task content that;

3 teaspoons is equivalent to 1 tablespoon.

Hence, 1/12 teaspoons is equivalent to;

= (1/12 ×1) ÷ 3

= 1/36 tablespoons.

On this note, one honeybee can make 1/36 tablespoons of honey in its lifetime.

Hence, if 2 tablespoons of honey is needed, the number of honeybees required is; 2/(1/36)

if the measure of arc CDE=118 degrees and the measure of arc EF=62 degrees calculate measure of angle FGE

Answers

The measure of angle FGE from the given figure is 28°.

Given that, the measure of arc CDE = 118° and the measure of arc EF = 62°.

How the measure of an arc and measure of an angle are related?

The measure of an arc is equal to the measure of its corresponding central angle.

From the given figure, the measure of arc CDE = 118° = corresponding central angle (∠CAE)

So, ∠CAE = 118°

From the given figure, the measure of arc FE = 62° = corresponding central angle (∠FAE)

So, ∠FAE = 62°

As we know the radius of a circle is perpendicular to the tangent.

That is, AE ⊥ EG

So, ∠AEG = 90°

Now, ∠AGE+∠AEG+∠GAE = 180° (The sum of interior angles of a triangle is equal to 180°)

∠AGE + 90° + 62° = 180°

⇒ ∠AGE + 152° = 180°

⇒ ∠AGE = 28°

So, ∠AGE = ∠FGE = 28°

Therefore, the measure of angle FGE from the given figure is 28°.

The square root of 155 is estimate according to the following compound inequality:

What is a compound inequality?

A compound inequality is a combination of multiple inequalities, at least two, involving operations such as and and or, explained below.

The and operation between multiple sets is composed by the elements that belong to all the sets.The or operation between multiple sets is composed by the elements that belong to at least one of the sets.

Hence one example of a compound inequality is:

x is greater or equal than a and less or equal than b.

For this problem, we have that:

12² = 144, hence sqrt(144) = 12.13³ = 169, hence sqrt(169) = 13.

Considering that 155 is between 144 and 169, and the square root function is increasing over it's entire domain, the square root of 155 is estimate according to the following compound inequality:
