The function that has a period of 4π and an amplitude of 6 is option B: y = 6 sin 2θ. To determine the period and amplitude of a trigonometric function, we examine the coefficients and constants within the function's equation.

The general form of a sinusoidal function is y = A sin(Bθ), where A represents the amplitude and B determines the period. The period is given by the formula T = 2π/B, where T is the period and B is the coefficient of θ.

Applying the formula for the period, we find T = 2π/2 = π.

The period of π represents half of the period we are looking for. To achieve a full period of 4π, we multiply the period by 2. Thus, the full period is 2π * 2 = 4π, which matches the desired period.

Next, we examine the amplitude. In option B, the amplitude is 6, as it is directly multiplied to the sine function.

Hence, option B: y = 6 sin 2θ is the function that has a period of 4π and an amplitude of 6, as requested.

The expected number of times a student who studies both biology and history is chosen can be calculated using the probability of selecting such a student in each trial.

To calculate the probability p, we need to know the total number of students in the class and the number of students who study both biology and history. Let's assume there are n students in the class and m students who study both biology and history.

The probability of selecting a biology and history student in one trial is given by m/n, as we are selecting one student out of the total number of students.

Therefore, the expected number of times a biology and history student is chosen in 60 trials is:

Expected number = 60 * (m/n)

For example, if there are 100 students in the class and 20 students study both biology and history, the probability of selecting such a student in one trial is 20/100 = 0.2. Thus, the expected number of times they will be chosen in 60 trials is 60 * 0.2 = 12.

In summary, to find the expected number of times a student who studies both biology and history is chosen in 60 trials, multiply the probability of selecting such a student in one trial by the total number of trials (60).

The given coordinates J(-7,-1), K(9,-5), and L(21,-8) do form a triangle.

To determine if the given coordinates form a triangle, we need to check if the three points are not collinear, meaning they do not lie on the same line. One way to verify this is by calculating the slopes between each pair of points. If the  slopes are different, then the points are not collinear and form a triangle.

Using the formula for slope, we find that the slope between J and K is -1/2, the slope between K and L is -3/4, and the slope between L and J is 1/14. Since these slopes are all different, the three points are not collinear, and therefore, they form a triangle.

The equation of a parabola with vertex at (1,1) and the directrix y=-1/2 is,

y = 3(x - 1)² + 1

Given that,

Vertex is (1, 1)

Equation of directrix y=-1/2

To write the equation of a parabola with vertex at (1,1) and the directrix

y = -1/2,

Use the standard form equation of a parabola:

(y - k) = 4p(x - h)²

Where (h, k) is the vertex of the parabola and p is the distance from the vertex to the focus and from the vertex to the directrix.

Since the vertex is (1,1),

We have h = 1 and k = 1.

Also, since the directrix is y = -1/2, the distance from the vertex to the directrix is p = 3/2 (because the vertex is 3/2 units away from y = -1/2).

So, substituting these values into the equation, we get:

(y - 1) = 4(3/2)(x - 1)²

Simplifying this equation, we get:

2(y - 1) = 6(x - 1)²

or

y = 3(x - 1)² + 1

The standard-form equation of the hyperbola with vertices (0, ±4) and foci (0, ±5) is:

x²/16 - y²/9 = 1.

The standard-form equation of a hyperbola with vertices (0, ±4) and foci (0, ±5) can be determined using the following formula:

For a hyperbola centered at the origin (h, k), the standard-form equation is given by:

(x - h)²/a² - (y - k)²/b² = 1, where a represents the distance from the center to the vertices and b represents the distance from the center to the foci.

In this case, since the center of the hyperbola is at (0, 0), the equation becomes:

x²/a² - y²/b² = 1.

To find the values of a and b, we can use the given information about the vertices and foci. Since the distance from the center to the vertices is 4, we have a = 4. Similarly, the distance from the center to the foci is 5, so we have c = 5.

We can use the relationship between a, b, and c for a hyperbola:

c² = a² + b²,

(5)² = (4)² + b²,

25 = 16 + b²,

b² = 25 - 16,

b² = 9,

b = 3.

Now we can substitute the values of a and b into the equation to get the standard-form equation of the hyperbola:

x²/4² - y²/3² = 1.

Therefore, the standard-form equation of the hyperbola with vertices (0, ±4) and foci (0, ±5) is:

Victoria charged her friend $112.50 for the pair of jeans she sold .To find out how much money Victoria charged her friend, we need to calculate 25% of the total amount she spent on the four jeans.

Victoria bought four jeans for a total of $450. To find 25% of $450, we multiply $450 by 25/100, which is the decimal representation of 25%.

25% of $450 = (25/100) * $450

                      = $0.25 * $450

                      = $112.50

Therefore, Victoria received $112.50 as a refund after selling one pair of jeans. This means she essentially got 25% of her money back.

Since Victoria sold one pair of jeans to her friend, she would charge her friend the original cost of that pair, which is equal to the price of the jeans she bought minus the refund she received.

Original cost of one pair of jeans = Cost of four jeans - Refund received

Original cost of one pair of jeans = $450 - $112.50 = $337.50

The conjecture is that in a quadrilateral formed by two pairs of parallel lines, the consecutive angles are supplementary.

Conjecture: In a quadrilateral formed by two pairs of parallel lines, the consecutive angles are supplementary.

Explanation: When two lines are parallel, the alternate interior angles formed by a transversal are congruent.

In a quadrilateral formed by two pairs of parallel lines, we have two transversals. Each transversal creates two pairs of congruent alternate interior angles, resulting in a total of four congruent angles. By the angle sum property of a quadrilateral, the sum of all four angles is 360 degrees.

Since the sum of consecutive angles in a quadrilateral is always 180 degrees, and we have four congruent angles, it follows that the consecutive angles in the quadrilateral are supplementary (add up to 180 degrees).

In this problem, the first and third angles on one side of the transversal measure 118° each, while the second and fourth angles measure 62° each. Same-side exterior angles formed by parallel lines and a transversal are congruent.

When investigating the relationship between same-side exterior angles formed by parallel lines and a transversal, we can start by drawing five pairs of parallel lines: m and n, a and b, r and s, j and k, and x and y. These lines are then intersected by a transversal, denoted as t.

By measuring the four angles on one side of the transversal, we find that one angle measures 118°, the second angle measures 62°, the third angle measures 118°, and the fourth angle measures 62°.

To understand the relationship between these angles, we can analyze the concept of same-side exterior angles. Same-side exterior angles are pairs of angles that lie on the same side of the transversal and are outside the parallel lines. In this case, we have two pairs of same-side exterior angles: the first angle and the third angle, and the second angle and the fourth angle.

The key property to observe is that same-side exterior angles are congruent. This means that the first angle is congruent to the third angle, and the second angle is congruent to the fourth angle. In other words, angle 1 = angle 3 and angle 2 = angle 4.

Based on the measurements provided, we can conclude that the first and third angles both measure 118°, while the second and fourth angles both measure 62°. This confirms the congruence between same-side exterior angles in this scenario.

To summarize, in the given problem, the measurements of the angles on one side of the transversal indicate that the first and third angles are congruent, measuring 118° each, while the second and fourth angles are also congruent, measuring 62° each.

The x-coordinates of the maximum or minimum points for the given equations are: a. Maximum point at x = 5/2, b. Minimum point at x = 2 and  c. Maximum point at x = 9/4.

To find the maximum or minimum points of the given quadratic equations, we need to determine the vertex of each parabola. The vertex represents the point where the function reaches its maximum (if the coefficient of the x² term is negative) or minimum (if the coefficient of the x² term is positive). The x-coordinate of the vertex can be found using the formula:

x = -b / (2a),

where a is the coefficient of the x² term and b is the coefficient of the x term.

a. For the equation y = -x² + 5x + 2, the coefficient of the x² term is -1, and the coefficient of the x term is 5. Plugging these values into the formula, we get:

[tex]x = -5 / (2 \times -1) = 5/2.[/tex]

Therefore, the vertex of the parabola is located at x = 5/2. Since the coefficient of the x² term is negative, this represents a maximum point.

b. For the equation y = 2x² - 8x + 10, the coefficient of the x² term is 2, and the coefficient of the x term is -8. Applying the formula, we have:

[tex]x = -(-8) / (2 \times 2) = 8 / 4 = 2.[/tex]

Hence, the vertex is at x = 2. As the coefficient of the x² term is positive, this corresponds to a minimum point.

c. Finally, for the equation y = -2x² + 9x - 1, the coefficient of the x² term is -2, and the coefficient of the x term is 9. Using the formula, we find:

[tex]x = -9 / (2 \times -2) = 9 / 4.[/tex]

Here, 'n' represents the number of years that have passed since the bone was living.

To solve for 'n', we can take the logarithm of both sides:

log(0.25) = log((1/2)^(n/5730))

Using logarithmic properties, we can bring the exponent down:

log(0.25) = (n/5730) * log(1/2)

Simplifying further:

log(0.25) = (n/5730) * (-0.3010)  (approximately, as log(1/2) ≈ -0.3010)

Now, we can solve for 'n':

n/5730 = log(0.25) / (-0.3010)

n ≈ (5730 * log(0.25)) / (-0.3010)

This means that x, the weight of peanuts, is equal to zero. However, since the total weight of the bag is 100 kg, there must be some peanuts in the bag. Therefore, there must be an error in the given information or calculation.

If we assume that the total weight of peanuts and almonds is 100 kg, we can solve for the quantities. Let's assign x as the weight of peanuts and y as the weight of almonds.

x + y = 100  (Total weight of the bag)

2x + 2.04y = 2.08 * 100  (Price equation)

Simplifying the equations, we have:

x + y = 100

2x + 2.04y = 208

Multiplying the first equation by 2, we get:

2x + 2y = 200

Subtracting this equation from the second equation, we have:

2x + 2.04y - (2x + 2y) = 208 - 200

0.04y = 8

y = 8 / 0.04

y = 200

Substituting the value of y into the first equation, we can solve for x:

x + 200 = 100

x = 100 - 200

x = -100

Since negative weight is not possible, we can conclude that there is an inconsistency or error in the given information or calculation.

a) The relationship between the height (h) and the square of the time (t^2) is given by h = k * t^2.

b) The constant of variation (k) can be calculated by substituting the given values into the relationship: 125 = k * 5^2. Solving for k, we find k = 5.

c) If a stone takes 3 seconds to reach the ground, we can use the relationship to find the height: h = 5 * 3^2. The height of the cliff is 45 meters.

d) To find the time taken for a stone to fall from a 180-meter high cliff, we rearrange the relationship: 180 = 5 * t^2. Solving for t, we find t = 6 seconds.

a) The relationship between the height (h) and the square of the time (t^2) can be expressed as:

h = k * t^2

b) To calculate the constant of variation (k), we can use the given information that a stone takes 5 seconds to reach the ground when dropped off a cliff 125 m high. Substituting these values into the relationship, we have:

125 = k * 5^2

125 = k * 25

Solving for k:

k = 125 / 25

k = 5

Therefore, the constant of variation is 5.

c) To find the height of a cliff if a stone takes 3 seconds to reach the ground, we can use the relationship and substitute the values:

h = k * t^2

h = 5 * 3^2

h = 5 * 9

h = 45

Thus, the height of the cliff would be 45 meters.

d) To find the time taken for a stone to fall from a cliff 180 m high, we need to rearrange the relationship and solve for t:

h = k * t^2

180 = 5 * t^2

Divide both sides by 5:

36 = t^2

Taking the square root of both sides:

t = √36

t = 6

Therefore, the time taken for a stone to fall from a cliff 180 meters high would be 6 seconds.

The statement that Study 2, with a sample size of 100 bottles, is more likely to provide a more precise estimate of the mean caffeine content of the energy drink compared to Study 1 is true.

Based on the given information, the statement that is true is that Study 2, which uses a larger sample size of 100 bottles, is more likely to provide a more precise estimate of the mean caffeine content of the energy drink compared to Study 1, which uses a smaller sample size of 25 bottles.

When estimating a population parameter, such as the mean, using a sample, a larger sample size generally leads to a more accurate and precise estimate.

In this case, Study 2 has a larger sample size, which means it provides more information about the variability of the caffeine content in the energy drink.

With a larger sample, the estimate of the mean caffeine content is likely to have a smaller margin of error and be more representative of the true population mean.

On the other hand, Study 1 with a smaller sample size is more susceptible to sampling variability and may have a larger margin of error. This means that the estimate obtained from Study 1 may have more uncertainty and be less reliable compared to Study 2.
