Let:

x = number we want to find

the sum of a number and 6 is multiplied by 5:

(x + 6)*5

the result is the same as 7 times the number increased by 16. So:

(x + 6)*5 = 7x + 16

Let's solve for x:

Use distributive property on the left hand side:

5x + 30 = 7x + 16

Subtract 5x from both sides:

5x + 30 - 5x = 7x + 16 - 5x

30 = 2x + 16

Subtract 16 from both sides:

30 - 16 = 2x + 16 - 16

14 = 2x

Divide both sides by 2:

14/2 = 2x/2

7 = x

Answer: the height of the pole is 16.782 meters

Step-by-step explanation: Let us take the height of the pole as "h".

i) Finding the height of the pole:

distance from the pole is 20m.

The angle of elevation is 40°

\(tan(40°) = h/20\)

Multiply both sides by 20:

\(20 * tan(40°) = h\)

\(h ≈ 20 * 0.8391 ≈ 16.782 meters\)

Therefore, the height of the pole is 16.782 meters.

ii) Finding the angle of depression

The angle of depression is the angle formed between the horizontal ground and the line of sight from the point of observation to the foot of the pole.

angle of depression = angle of elevation = 40°

Therefore, the angle of depression of the foot of the pole from the point of observation is 40°.

https://brainly.com/question/88158

Using trigonometric methods, it is determined that the height of the pole is found by using the formula for tangent, and adding the height of the observer. The angle of depression equals the angle of elevation, so both are 40 degrees.

To solve the problem, we use the properties of a right triangle and trigonometric functions. Since we know the angle of elevation and the length of one side, we can find the length of the other side using the tangent function.

For the height of the pole: we know that tan(θ) = opposite/adjacent, so,
tan(40) = height/20
height = tan(40) * 20

Let's denote the observer's height as h=1.54m, so the total height of the pole is height + h.

For the angle of depression: In a right triangle, the angle of depression and the angle of elevation are equal. Therefore, the angle of depression is also 40 degrees.

frequency, or the variable b, is related to the period. (Specifically, it frequency is the value you divide the original period by to get the new period).

the original unchanged period of the tangent function is pi.

In this case however, we see the period, (one cycle), is going from 3pi to 9pi/2. this means the period is 3pi/2. Since we divide pi by 2/3 to get to 3pi/2, our frequency, or b, is 2/3.

The APR, or stated rate, is calculated as the annualized interest rate expressed as a percentage.

The APR, or stated rate, represents the annualized interest rate on a loan or investment, expressed as a percentage.

To calculate the APR, we need to consider the nominal interest rate and the compounding frequency. The formula to calculate the APR is:

APR = (1 + nominal interest rate/compounding periods)^(compounding periods) - 1

The nominal interest rate is the stated rate without taking compounding into account.

The compounding periods refer to the number of times interest is compounded in a year, typically based on daily, monthly, or quarterly periods.

By applying the formula and considering the appropriate compounding periods, we can determine the APR.

The APR is an important metric as it allows for easy comparison of interest rates across different financial products.

It helps consumers and investors understand the true cost or yield associated with a loan or investment and enables them to make informed decisions.

Here, y = weekly hours of sport

x = Time to run

For x = 50 minutes,

Since, slope of the given regression line is negative, correlation will be negative (n).

The value of h that makes the vectors linearly dependent is h = 4.

What is the determinant?

The determinant is a mathematical operation defined for square matrices. It is denoted by the symbol det(A) or |A|, where A represents a square matrix.

To determine the value(s) of h for which the vectors [3, -3, 9], [9, -12, 26], and [-2, 2, h] are linearly dependent, we need to check if there exists a non-trivial solution to the equation:

a[3, -3, 9] + b[9, -12, 26] + c[-2, 2, h] = [0, 0, 0],

where a, b, and c are constants.

Expanding this equation, we get:

[3a + 9b - 2c, -3a - 12b + 2c, 9a + 26b + ch] = [0, 0, 0].

This leads to the following system of equations:

3a + 9b - 2c = 0,   (1)

-3a - 12b + 2c = 0,  (2)

9a + 26b + ch = 0.  (3)

To determine if there exists a non-trivial solution, we can perform row reduction on the augmented matrix of this system.

The augmented matrix is:

[3   9  -2 | 0]

[-3 -12  2 | 0]

[9   26  h | 0]

By applying row reduction operations, we can simplify the matrix:

[R2 + R1 → R2]

[R3 - 3R1 → R3]

[R3 - 3R2 → R3]

[R2/(-3) → R2]

[3   9  -2  | 0]

[1   4  -2  | 0]

[0   0  h-4 | 0]

From the reduced row echelon form, we see that for the vectors to be linearly dependent, the determinant of the coefficient matrix must be zero:

det([3  9  -2]

   [1  4  -2]

   [0  0  h-4]) = 0.

Expanding this determinant, we get:

3(4(h - 4) - (-2)(0)) - 9(1(h - 4) - (-2)(0)) + (-2)(1(0) - 4(h - 4)) = 0.

Simplifying the equation gives:

12h - 48 + 9h - 36 + 8h - 32 = 0,

29h - 116 = 0,

29h = 116,

h = 116/29,

h = 4.

Therefore, the value of h that makes the vectors linearly dependent is h = 4.

The probability that a student participates in clubs, the student is a girl, is approximately 0.588.

Let's define:

G:

The circumstance a pupil is a female.

C:

The activity in a student engages with clubs.

In the event G, 17 students are female, 11 students are club members, and 10 students are female and club members in the event G and C.

Calculate P(C|G), or the probability of event C provided that event G has occurred, to determine if a student joins clubs given that she is a girl.

Using the conditional probability formula, we have:

P(C and G) / P(G) = P(C|G)

P(C and G) = 10/32 because 10 students are both ladies and take part in clubs (events G and C).

Additionally, according to event G, there are 17 girls in the class.P(G) = 17/32.

The probability that a student participates in clubs, given that the student is a girl, is:P

(C|G) = (10/32) / (17/32)

Answer: m = 55

n = 135

p = 45

Explanation:

Since the two lines are parallel, B = M. So, M = 55 The angle of a line is 180, so I subtracted 180 by the two angles of the triangle, 80 and 55, and I got 45. So P = 45.

P is equal to the right side of the smaller triangle. The angle of a line is 180, so I subtracted 180 by 45 to get 135. So N = 135. I am not sure if my answer is correct though because I’m still in middle school.

A(n) experiment can be used to establish a cause and effect relationship between the explanatory and response variables.

In an experiment, researchers actively manipulate the explanatory variable (also known as the independent variable) to observe its effect on the response variable (also known as the dependent variable). By controlling and manipulating the conditions of the experiment, researchers can establish a cause and effect relationship between the variables.

The key characteristic of an experiment is the ability to assign participants or subjects randomly to different treatment groups. This random assignment helps ensure that any observed effects on the response variable are due to the manipulation of the explanatory variable and not due to other confounding factors.

By conducting experiments, researchers can gather strong evidence to support or refute hypotheses about causal relationships. The experimental design allows for rigorous control over potential sources of bias and provides a foundation for drawing conclusions about cause and effect.

It is important to note that while experiments are powerful in establishing causality, they may not always be feasible or ethical for certain research questions. In such cases, other study designs, such as observational studies, can provide valuable insights, but establishing causal relationships becomes more challenging.
