Answer:  the simplified form of sec(Q) is sqrt(24/7).

Step-by-step explanation: The equation secant of angle Q is equal to two multiplied by the square root of six and divided by nine.

In order to reduce the complexity of the given mathematical expression, it is possible to employ the fundamental definition of secant, which states that:

The trigonometric identity denoted as sec(Q) equals the reciprocal of the cosine function evaluated at the angle Q. More precisely, sec(Q) = 1 / cos(Q).

The value of cos(Q) may be determined through the utilization of the Pythagorean identity.

The present mathematical equation demonstrates a fundamental identity in trigonometry, wherein the squares of the sine and cosine functions are summed to equal one. Written symbolically, the equation can be expressed as sin^2(Q) + cos^2(Q) = 1.

Given the condition that sec(Q) is positive, it is ascertainable that Q is situated within the first or fourth quadrant, wherein the cosine of Q is likewise positive. Consequently, the derivation for the solution of the cosine of the angle Q can be expressed as follows:

The trigonometric identity expressed as cos(Q) = sqrt(1 - sin^2(Q)) is a fundamental result in the field of mathematics. This particular equation provides a relationship between the cosine and sine functions of angle Q. Specifically, it states that the cosine of an angle Q is equal to the square root of one minus the sine squared of the same angle Q. The use of such identities is common in mathematical analysis and applied sciences, where it allows for efficient manipulation of trigonometric functions and the mathematical modeling of a variety of physical phenomena.

The following mathematical expression can be written in an academic style: Cosine of angle Q can be expressed as the square root of one minus the square of nine divided by twice the square root of six, i.e., cos(Q) = √(1 - (9/2√6)^2), while substituting the value of sine of angle Q as being equal to nine divided by twice the square root of six (i.e., sin(Q) = 9/2√6).

The mathematical expression cos(Q) = sqrt(1 - (81/24)) may be represented in a more academic manner. Specifically, it may be articulated as follows: the cosine of angle Q is equivalent to the square root of one subtracted by the quotient of 81 and 24. This revision lends itself to a more formal and precise mode of communication, which is characteristic of academic writing.

The mathematical expression cos(Q) = √(7/24) can be represented in a formal and academic manner.

The value of secant of angle Q can now be determined as:

The trigonometric function defining the secant of an angle Q is expressed as sec(Q) = 1/cos(Q).

The trigonometric function, sec(Q), can be expressed as the reciprocal of the square root of 7/24.

The mathematical statement, sec(Q) = sqrt(24/7), can be expressed in a formal and academic manner as follows. The reciprocal of the cosine function of the angle Q is equivalent to the square root of the fraction 24 over 7.

a) The angular velocity of the wheel is approximately 1.0667 radians per second. b) The wheel will spin at approximately 10.16 revolutions per minute.

Angular velocity is a measure of how quickly an object rotates or revolves around a fixed point, such as an axis or a center of rotation. It is a vector quantity that describes the rate of change of an object's angular position with respect to time, and is usually expressed in units of radians per second (rad/s) or degrees per second (deg/s).

a) To find the angular velocity of the wheel, we can use the formula:

angular velocity = linear velocity / radius

In this case, the linear velocity of the hamster is 16 centimeters per second, and the radius of the wheel is 15 centimeters. So, we have:

angular velocity = 16 / 15

angular velocity = 1.0667 radians per second

Therefore, the angular velocity of the wheel is approximately 1.0667 radians per second.

b) To find the speed of the wheel in revolutions per minute, we need to convert the angular velocity from radians per second to revolutions per minute. There are 2π radians in one revolution, and 60 seconds in one minute. So, we can use the following formula:

angular velocity (in revolutions per minute) = angular velocity (in radians per second) * 60 / 2π

Plugging in the angular velocity we found in part (a), we get:

angular velocity (in revolutions per minute) = 1.0667 * 60 / 2π

angular velocity (in revolutions per minute) ≈ 10.16 revolutions per minute

Therefore, the wheel will spin at approximately 10.16 revolutions per minute.

What is arithmetic sequence?

An arithmetic sequence is a sequence of numbers in which each term after the first is found by adding a fixed constant number, called the common difference, to the preceding term.

Let's start by finding the fraction of Michelle's patients who are under 12 or over 65. We know that one-third of her patients are under 12, so two-thirds must be 12 or older. Similarly, five-twelfths of her patients are over 65, so seven-twelfths must be 65 or younger.

Now, we want to find the fraction of Michelle's patients who are between 12 and 65. To do this, we need to subtract the fraction of patients who are under 12 or over 65 from 1 (since these are the only two age groups we're considering).

Fraction of patients under 12: 1/3

Fraction of patients over 65: 5/12

Fraction of patients 12 to 65: 1 - 1/3 - 5/12

We can simplify this expression by finding a common denominator:

Fraction of patients 12 to 65: 12/12 - 4/12 - 5/12

Fraction of patients 12 to 65: 3/12

Simplifying this fraction gives us 1/4. Therefore, the answer is (D) 1/4.

What is combination?

In mathematics, a combination is a way of selecting objects from a larger group of objects, where the order of selection is not important. A combination is a subset of objects that are chosen from a larger set without regard to the order in which they are selected.

The formula  is given by:

C(n, r) = [tex]\frac{n!}{r!* (n - r)!}[/tex]

The total number of ways to choose 5 CDs from a collection of 23 CDs is given by the combination formula:

C(23, 5) = [tex]\frac{23!}{5!* (23 - 5)!}[/tex]

             = 33649

This means there are 33649 different ways to arrange 5 CDs out of the 23 CDs.

Out of these 33649 ways, only one arrangement is alphabetical. For this to happen, the first CD chosen must be the first one alphabetically, the second CD chosen must be the second one alphabetically, and so on.

The first CD can be any of the 23 CDs. However, once the first CD is chosen, there is only one CD that can be the second one alphabetically, two CDs that can be the third one alphabetically, and so on. Therefore, the probability of choosing 5 CDs in alphabetical order is:

P = 1 / C(23, 5)

P = 1 / 33649

P ≈ 0.00003

So the probability of choosing 5 CDs in alphabetical order out of a collection of 23 CDs is approximately 0.00003 or 0.003%.

To find the specified scalar, we need to first find the dot product of U and V, and then the dot product of U and W, and add these two dot products together:

U·V + U·W

where U·V denotes the dot product of U and V, and U·W denotes the dot product of U and W.

The dot product of two vectors a = (a1, a2) and b = (b1, b2) is given by:

a · b = a1b1 + a2b2

Using this formula, we can find the dot product of U and V:

U · V = (4i - j) · (5i + j) = 4i · 5i + 4i · j - j · 5i - j · j = 20i^2 + (4i · j - 5i · j) - j^2 = 20 + (-i · j) - 1 = 19 - i · j

Next, we can find the dot product of U and W:

U · W = (4i - j) · (i + 6j) = 4i · i + 4i · 6j - j · i - j · 6j = 4i^2 + (4i · 6j - j · i) - 6j^2 = 4 + (24i · j) - 6 = -2 + 24i · j

Now we can substitute these values into the original expression:

U·V + U·W = (19 - i·j) + (-2 + 24i·j) = 17 + 23i·j

Therefore, the specified scalar is 17 + 23i·j.

The reason why it is possible to draw two different rectangles that have an area of 30 square inches is that there are multiple pairs of whole numbers that multiply to 30. For example, a rectangle with dimensions 5 inches by 6 inches has an area of 30 square inches, and so does a rectangle with dimensions 2 inches by 15 inches.

However, the number 7 is a prime number, which means it can only be divided evenly by 1 and itself. Therefore, the only way to get an area of 7 square inches for a rectangle is by multiplying 1 and 7, which means the dimensions of the rectangle would be 1 inch by 7 inches. Since there are no other pairs of whole numbers that multiply to 7, it is not possible to draw two different rectangles with an area of 7 square inches.
