The unknown measures and angle measures are:

A. LH ≈ 45.68; m∠K ≈ 55°; m∠L ≈ 35°

Trigonometry deals with the relationship between the ratios of the sides of a right-angled triangle with its angles.

The  unknown measures of the triangle can be founding as follow:

LH² = 56² - 32.4²  (Pythagoras Theorem)

LH = √(56²- 32.4²)

LH = 45.68 units

sin K = 45.68/56

K = sin⁻¹(45.68/56)

K ≈ 55°

Thus, m∠K ≈ 55°

sin L =  32.4/56

L = sin⁻¹( 32.4/56)

L ≈ 35°

Thus, m∠L ≈ 35°

Answer: $6,320.25

Step-by-step explanation:

Mrs. Cowley's broker fee is calculated by multiplying the purchase price by the broker fee percentage: $32,000 x 0.0075 = $240. Her total cost for the purchase is then $32,000 + $240 = $32,240. When she sells the stock for $25,100, she incurs another fee of $17 for using the discount broker. To calculate her net loss, we subtract her total cost from her selling price and subtract the two broker fees: $25,100 - $32,240 - $17 - $17 = -$6,320.25, which is rounded to $6,320.25 as a net loss.

Answer:

When two parallel lines are intersected by a transversal, the alternate interior angles are the pairs of non-adjacent angles that are located between the two parallel lines and on opposite sides of the transversal. These angles are congruent, which means they have the same measure. The other type of angles mentioned in the statement, which are supplementary, are the pairs of adjacent angles that are located on the same side of the transversal and outside the parallel lines. These angles add up to 180 degrees.

The correct choice is "consecutive interior angles are supplementary."

As per the Pythagorean theorem, the length of the missing side, c, is approximately 8.06 units.

Pythagorean Theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

Now, let's use the Pythagorean Theorem to find the length of the missing side in your problem. You have a right-angled triangle with side a = 4 and side b = 7. To find the length of the missing side, let's call it c, we need to use the Pythagorean Theorem, which is:

c² = a² + b²

In this case, we know the values of a and b, so we can substitute them into the equation:

c² = 4² + 7²

Simplifying the right-hand side, we get:

c² = 16 + 49

c² = 65

To solve for c, we need to take the square root of both sides of the equation:

c = √65

c ≈ 8.06

The probability of passing the test by random guessing is 0.003%.

To estimate the probability of passing a true/false test of 70 questions, we can use the normal approximation to the binomial distribution. Since each question has only two possible outcomes (true or false), the binomial distribution can be used to calculate the probability of getting a certain number of correct answers out of 70.

The mean of the binomial distribution can be calculated as np, where n is the number of trials (70) and p is the probability of success (0.5, since the responses are random guesses). The standard deviation of the binomial distribution can be calculated as the square root of np*(1-p).

To find the probability of passing the test, we need to find the number of correct answers required to achieve a score of 80% or higher. Since 80% of 70 is 56, we need to get at least 56 questions correct.

Using the normal approximation, we can approximate the binomial distribution with a normal distribution with mean 35 and standard deviation 4.79. To find the probability of getting at least 56 questions correct, we can standardize the value (56-35)/4.79 = 4.02 and look up the probability in a standard normal table. The probability of getting at least 56 questions correct is approximately 0.00003.

According to the information, the ball returns to the ground about 13.6 feet away.

To calculate how many feet away the ball returns to the ground we have to consider that the ball starts 0 feet above the ground (assuming the ground level is the reference point, where h(x) = 0).

To find the maximum height, we need to find the vertex of the parabola, which occurs at

x = -b/2a

where,

a = -0.25

b = 3.4.

x = -3.4 / (2 * (-0.25)) = 6.8

So, the ball reaches a max height of h(6.8) = -0.25(6.8)^2 + 3.4(6.8) = 8.2 feet at a horizontal distance of 6.8 feet away from the club it was hit with.

To find when the ball returns to the ground, we set h(x) = 0 and solve for x:

0 = -0.25x^2 + 3.4x

0.25x(13.6 - x) = 0

x = 0 or x = 13.6

Since x = 0 is the starting point, the ball returns to the ground at x = 13.6 feet away from the club it was hit with.

Therefore, the ball returns to the ground about 13.6 feet away.

Reflecting a point across the x-axis changes the sign of its y-coordinate while keeping the x-coordinate intact. As such, Z' can be rewritten in terms of (x, -y).

If a rectangle shifts downward by five units and rightward by three units, the transformation rule can be expressed as: (x, y) → (x + 3, y - 5).

Conversely, the given equation for this specified action is: (x, y) → (x - 3, y - 4).

Similar but reversed in reflection across the y-axis, where instead it is the x-coordinate that sees its sign changed, given the conditions that the y-coordinate stays constant. Hence, the transformation can be stated as: (x, y) → (-x, y).

The same applies for a mathematical exchange when it comes to reflecting about the x-axis; here the y-coordinate has its signs reversed with no transition in the x-coordinate – simply put, we have as follows: (x, y) → (x, -y).

The angle in the rectangular coordinate system is 0 degrees, the compass bearing of the airplane is N (north).

The slope of the line can be found using the formula:

slope = (change in y-coordinate) / (change in x-coordinate)

In this case, the change in the y-coordinate is 0, and the change in the x-coordinate is 10. Therefore, the slope of the line is:

slope = (0 - 0) / (10 - 0) = 0

Since the slope of the line is 0, the line is horizontal, and the angle it makes with the x-axis is 0 degrees or 180 degrees. However, we need to determine which of these angles is the correct bearing of the airplane relative to the observer.

Since the airplane is in the positive x-axis, it lies in Quadrant I. In this quadrant, the angle that a line makes with the positive x-axis is measured counterclockwise from the positive x-axis.

Therefore, the angle that the line connecting the observer to the airplane makes with the positive x-axis is 0 degrees. This is the bearing of the airplane relative to the observer.

To express the bearing using the compass bearing method, we need to convert the angle from the rectangular coordinate system to the angle measured in degrees clockwise from the north direction.
