Answer:

Step-by-step explanation:

a. The equation of the line that describes the relationship between distance and time for Car X can be found by using the slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.

To find the slope (m), we can use the formula: m = (change in y) / (change in x) = (distance traveled) / (time elapsed) = 174 miles / 3 hours = 58 miles per hour.

Since the car starts at time x = 0 and has traveled 174 miles at time x = 3, the y-intercept (b) can be found by setting x = 0 and solving for y: y = 58x + b, and y = 174 when x = 3, so b = 174 - 58(3) = -160.

Putting it all together, we get the equation: y = 58x - 160.

b. The graph that represents the relationship between distance and time for Car X is a line that passes through the point (0, -160) and has a slope of 58. This line represents the linear relationship between the distance traveled and the time elapsed for Car X.

The y-intercept of -160 represents the distance traveled when time is equal to 0. The slope of 58 represents the rate of change of the distance traveled with respect to time. This means that for every hour that passes, Car X travels 58 miles.

a)  The sample space for this experiment:

S = { E1E2, E1W2,E2W2, E1W1, E2W1, W1W2 }

b) The probability that the expert will correctly identify (by guessing) both of the cans containing water is:  1/6

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.

Now, According to the information:

Let E1 and E2 represent the empty cans and W1 and W2 be the cans filled with water.  

S = { E1E2, E1W2,E2W2, E1W1, E2W1, W1W2 }  

By merely guessing, the events are equally likely. Since there are 6 possible outcomes,  

The probability that the expert will correctly identify (by guessing) both of the cans containing water is:

Since there are 6 possible outcomes,  

probability = 1/6

According to Webster’s New Collegiate Dictionary, a divining rod is "a forked rod believed to indicate [divine] the presence of water or minerals by dipping downward when held over a vein." To test the claims of a divining rod expert, skeptics bury four cans in the ground, two empty and two filled with water. The expert is led to the four cans and told that two contain water.

According to the mathematical calculations made, the results are as follows: the length of DF is 3.87 cm, the length of XF is 4.89 cm. The point 2cm from E is 5cm from X and the angle of D is 60°.

In this problem, we have to apply the Pythagorean theorem to find the lenght of DF line.

a² + b² = c²

7² + b² = 8²

49 + b² = 64

b² = 15

b = 3.87

In this problem, we have to apply the Pythagorean theorem to find the lenght of XF line.

a² + b² = c²

3² + 3.87² = c²

9 + 14.97 = c²

23.97 = c²

4.89 = c

According to the information of the graph we can conclude that the point 2cm from E is on the line EX, and it is located 2cm from E and 5cm from X.

We know that F has a angle less than D so we can infer that F has an angle of 30° and D has an angle of 60° which we can check with a compass.

The value of x is 7.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

∠TUV = 9x + 1

∠TUW = 7x - 9

∠WUV = 5x - 11

Now,

∠TUV = ∠TUW + ∠WUV

Substituting the values.

9x + 1 = 7x - 9 + 5x - 11

Adding like terms.

9x + 1 = 12x - 20

1 + 20 = 12x - 9x

21 = 3x

Dividing 3 on both sides.

x = 21/3

x = 7

Thus,

x is 7.

The percent markup for the cost of shirt = 50%

Let us assume that the cost of each shirt be x dollars

A department store buys 300 shirts at a cost of $1,800.

Using unitary method the price of each shirt would be,

x = 1800/300

x = 6 dollars

A department store sells 300 shirts for $9 each.

So, Selling price of one shirt = $9

Price markup = Selling price - Cost price

                      = $9 - $6

                      = $3

The percent markup would be,

p = (Price markup / cost price) × 100

p = (3/6) × 100

p = 50%

Therefore, the percent markup = 50%

The possible values are -

(a²,b²) = p

(a²,b) = p if p|-r and (a²,b) = p² if p|r

(a²,b³) = p² if p|-r and (a²,b³) = p³ if p|r

What is gcd?

The greatest common factor (GCF) that divides two or more numbers is known as the greatest common divisor (GCD). The highest common factor is another name for it (HCF).

Since (a, b) = p it can be written a = pr and b = ps where r and s are integers such that (r, s) = 1.

Then a² = p²r².

Then by Theorem 1.7, (a²,b) = (p²r²,ps) = p(pr²,s).

By Theorem 1.8, (r²,s) = 1 .

Thus, there are two cases to consider: if p|s then, (a²,b) = p², and if p|-s then (pr²,s) = 1 (Again by Theorem 1.8)  so that (a²,b) = p in that case.

Thus, there are two cases for (a²,b): namely p or p².

The same analysis shows that (a³,b) must be either p, p² or p³ depending on the power of p that divides b.

Analyze (a²,b³) as follows.

Using the notation already introduced, and

Theorem 1.7, it is obtained that (a²,b³) = (p²r²,p³s³) = p²(r²,ps³).

Since, (r, s) = 1, Theorem 1.8 shows that (r²,s³) = 1.

Therefore, there are two possibilities for (a²,b³) -

(a²,b³) = p² if p|-r and (a²,b³) = p³ if p|r.

Step-by-step explanation:

The velocity of the particle at a given value of θ can be found by taking the derivative of the position vector with respect to time:

v(θ) = dr/dt = dr/dθ * dθ/dt = dr/dθ * ω

where ω is the angular velocity and dr/dθ is the derivative of the position vector with respect to θ.

The position vector r = a * e^(b * θ) * i + a * b * e^(b * θ) * j

Taking the derivative with respect to θ:

dr/dθ = a * b * e^(b * θ) * i + a * b^2 * e^(b * θ) * j

So the velocity of the particle is given by:

v(θ) = a * b * e^(b * θ) * ω * i + a * b^2 * e^(b * θ) * ω * j

The measure of angle Y, according to the stated statement, is 55 degrees.

An adverb used to describe something which goes together with something else and improves or completes it is complimentary (as in complementary colors)

The total of two complimentary angles is 90 degrees. As a result, we have:

m∠S + m∠Y = 90

Substituting the given equation m∠S = 5(m∠Y) − 240°, we get:

5(m∠Y) − 240° + m∠Y = 90

By merging like variables in the equation, we can reduce it to:

6(m∠Y) - 240° = 90

Adding 240 to both sides, we get:

6(m∠Y) = 330

Dividing both sides by 6, we get:

m∠Y = 55

Therefore, the measure of angle Y is 55 degrees.

The distance across the lake is approximately 62.5 meters, rounded to the nearest hundredth of a meter.

To find the distance across the lake (BC), we can use the following formula based on triangle similarity:

BC/AD = DB/DE

Where BC is the distance across the lake, AD is the known direct measurement made by Dominic, DB is the known measurement from point B to the landmark, and DE is the known measurement from point D to the landmark.

Let's assume that AD = 100 meters, DB = 50 meters, and DE = 80 meters. Then we can calculate BC as follows:

BC = (BC/AD) * AD = (DB/DE) * AD

BC = (50/80) * 100

BC = 62.5 meters
