Answer:

A

Step-by-step explanation:

Since the coefficient of the x² term is negative (we know this because if you look at C, the coefficient of x² is -2, which is negative) we know that the vertex will be the maximum. To find the vertex without having to be rewritten, a quadratic function should be written in vertex form which is y = a(x - c)² + d where (c, d) is the vertex. The answer choice that is written in vertex form is A.

The measure of ∠5 is 35degree

Linear pair of angles are produced when two lines intersect each other at a point. The sum of angles of the linear pair is always 180 degrees.

Given:

In Quadrilateral ABCD, AB||CD

<M2=35

If a transversal line intersects two parallel lines then the alternate interior angles are congruent.

In the given figure In Quadrilateral ABCD, AB||CD<M2=35  .

So,

<5≅<2 (Alternate interior angles)

M<5=M<2

M<5=35degree

First things first, we need to simplify (8^2)^-4. When a number is raised to a power, and the result of that is raised to another power, the two powers can be multiplied together to simplify. In this case, 2 * -4 = -8, so the question is asking how 8^-8 can be written.

8^-8 is the same as multiplying 8 8s together, and then finding the reciprocal (put it into a fraction where the original number is the denominator and 1 is the numerator).

The question is an example of theoretical probability, since it does not involve actually selecting marbles from the bag, while empirical probability is based on actual observations or experimental data.

Theoretical probability is the probability of an event based on mathematical analysis or reasoning, without actually performing an experiment or collecting data.

Here given question is an example of theoretical probability.

Theoretical probability is the probability of an event based on a theoretical or mathematical calculation, without actually performing an experiment or collecting data. In this case, we can calculate the probability of choosing a blue marble by dividing the number of blue marbles (8) by the total number of marbles;

the total number of marbles in the bag = 7 + 8 + 9 = 24

P(Blue) = 8/24 = 1/3

This calculation is based on theoretical probability, since it does not involve actually selecting marbles from the bag to determine the proportion of blue marbles. In contrast, empirical probability is based on actual observations or experimental data.

The expression for the final price of a hat would be h(0.775)(0.08875) and the final price of buying four hats after the discount and sales tax would be $142.

Option (C) is correct.

What is a discount?

A discount is a reduction in the price of a product or service. It can be offered for a variety of reasons, such as to encourage customers to make a purchase or to clear inventory. Discounts can be expressed as a percentage off the original price, or as a fixed dollar amount.

Part A: The expression that would calculate the final price of a hat is h(0.775)(1.08875). This takes into account the 22.5% discount by multiplying the original price by 0.775, and then adds the 8.875% sales tax by multiplying the discounted price by 1.08875.

Part B: If the original price of a hat is $42, then the final price of buying four hats after the discount and sales tax would be $42 x 4 x 0.775 x 1.08875 = $142.

Hence, the expression for the final price of a hat would be h(0.775)(0.08875) and the final price of buying four hats after the discount and sales tax would be $142.

The function f(x,y) has local minima at all points of the form (2nπ, 0) and (mπ, 2) for even integers m, and local maxima at all points of the form (mπ, 0) for odd integers m. It has no saddle points.

To find the local maximum and minimum values and saddle point(s) of the function f(x,y) = y^2 - 2y cos(x), -1 ≤ x ≤ 7, we need to find the critical points of the function and analyze their nature.

First, we find the partial derivatives of f with respect to x and y:

∂f/∂x = 2y sin(x)

∂f/∂y = 2y - 2cos(x)

Setting these partial derivatives equal to zero, we get:

2y sin(x) = 0 (Equation 1)

2y - 2cos(x) = 0 (Equation 2)

From Equation 1, we get either y = 0 or sin(x) = 0.

Case 1: y = 0

Substituting y = 0 in Equation 2, we get cos(x) = 1, which gives x = 2nπ, where n is an integer. The critical points are (2nπ, 0).

Case 2: sin(x) = 0

Substituting sin(x) = 0 in Equation 1, we get y = 0 or x = mπ, where m is an integer. If y = 0, then we have already considered this case in Case 1. If x = mπ, then substituting in Equation 2, we get y = 1 - cos(mπ) = 2 for even values of m and y = 1 - cos(mπ) = 0 for odd values of m. The critical points are (mπ, 2) for even m and (mπ, 0) for odd m.

Therefore, the critical points are: (2nπ, 0) for all integers n, (mπ, 2) for even integers m, and (mπ, 0) for odd integers m.

Next, we find the second partial derivatives of f:

∂^2f/∂x^2 = 2y cos(x)

∂^2f/∂y^2 = 2

∂^2f/∂x∂y = 0

At the critical points, we have:

(2nπ, 0): ∂^2f/∂x^2 = 0, ∂^2f/∂y^2 = 2 > 0, and ∂^2f/∂x∂y = 0, so this is a minimum point.

(mπ, 2) for even integers m: ∂^2f/∂x^2 = -2y, ∂^2f/∂y^2 = 2 > 0, and ∂^2f/∂x∂y = 0, so this is a minimum point.

(mπ, 0) for odd integers m: ∂^2f/∂x^2 = 0, ∂^2f/∂y^2 = 2 > 0, and ∂^2f/∂x∂y = 0, so this is a minimum point.

The probability that the dictionary is selected is 0.417, 3 novels and 2 books of poems are selected is 0.707. The probability that 4 novels are selected is 0.354.

The probability that the dictionary is selected, we need to determine the total number of ways to select 5 books from the shelf, as well as the number of ways to select the dictionary and 4 other books.

The total number of ways to select 5 books from the shelf is:

C(12,5) = 12! / (5! * 7!) = 792

The number of ways to select the dictionary and 4 other books is:

C(1,1) * C(11,4) = 11! / (4! * 7!) = 330

Therefore, the probability that the dictionary is selected is:

P(dictionary) = 330/792 = 0.417

The probability that 3 novels and 2 books of poems are selected, we need to determine the total number of ways to select 5 books from the shelf, as well as the number of ways to select 3 novels and 2 books of poems.

The total number of ways to select 5 books from the shelf is:

C(12,5) = 12! / (5! * 7!) = 792

The number of ways to select 3 novels and 2 books of poems is:

C(8,3) * C(3,2) = (8! / (3! * 5!)) * (3! / (2! * 1!)) = 560

Therefore, the probability that 3 novels and 2 books of poems are selected is:

P(3 novels, 2 books of poems) = 560/792 = 0.707

The probability that 4 novels are selected, we need to determine the total number of ways to select 5 books from the shelf, as well as the number of ways to select 4 novels and 1 other book.

The total number of ways to select 5 books from the shelf is:

C(12,5) = 12! / (5! * 7!) = 792

The number of ways to select 4 novels and 1 other book is:

C(8,4) * C(4,1) = (8! / (4! * 4!)) * (4! / (1! * 3!)) = 280

The number of significant figures for each given value is as follows: 0.098200 has 5 significant figures, 1.68×10^4 has 3 significant figures, 78,000,120 has 9 significant figures, and 1.008 has 4 significant figures.

Significant figures represent the precision and accuracy of a number. They include all the digits that carry meaning in a measurement or calculation. In the case of 0.098200, all the digits are non-zero and are considered significant. Therefore, it has 5 significant figures.

For 1.68×10^4, the number is written in scientific notation. The digits before the multiplication sign represent the significand, which in this case is 1.68. The exponent of 10 indicates the number of places the decimal point is moved to obtain the actual value. In this case, it is 4, which means the decimal point is moved four places to the right. The significand, 1.68, has three significant figures, and the exponent of 10 does not affect the significant figures. Therefore, the value has 3 significant figures.

In 78,000,120, the zeros are considered significant because they are between nonzero digits. Hence, all the digits contribute to the significant figures, resulting in 9 significant figures.

Lastly, for 1.008, the trailing zero after the decimal point is significant, as it indicates precision. Therefore, it has 4 significant figures.

In summary, the number of significant figures for each given value is 0.098200 with 5 significant figures, 1.68×10^4 with 3 significant figures, 78,000,120 with 9 significant figures, and 1.008 with 4 significant figures.

Millimeters can be converted into centimeters by dividing the value by 10. The solution has been obtained by using the unit conversion.

What is unit conversion?

A unit conversion is used to express the same property in a different unit of measurement. For instance, you could use minutes instead of hours to represent time or feet instead of miles to indicate distance. It commonly occurs when measurements are provided in one system of units, such as feet, but are required in a different system, such as chains.

We are required to convert millimeters to centimeters.

We know that 1 centimeter = 10 millimeters

So, for converting millimeters to centimeters, we need to divide the value by 10.

Hence, millimeters can be converted into centimeters by dividing the value by 10.
