The area of triangle TUV with vertices T(-8,2), U(-2,8), and V(-9,9) are 13.4 units.

A triangle is a closed two-dimensional plane figure that has three sides, three angles, and three vertices. The sum of the angles of a triangle is always 180 degrees. Triangles can be classified based on the length of their sides and the size of their angles. Some common types of triangles include equilateral, isosceles, scalene, acute, obtuse, and right triangles. Triangles are a fundamental concept in geometry and are used in many areas of mathematics and science.

Here,

To find the area of triangle TUV, we can use the formula:

Area = 1/2 * base * height

We can choose any two sides of the triangle as the base and the corresponding height. Let's choose TU as the base and the perpendicular distance from V to TU as the height.

First, let's find the length of TU:

TU = √[(8 - 2)² + (-2 - (-8))²]

= √[6² + 6²]

= 6√(2)

Next, let's find the slope of TU:

mTU = (8 - 2) / (-2 - (-8))

= -3/2

The line perpendicular to TU passing through V has a slope equal to the negative reciprocal of mTU:

mVQ = 2/3

The equation of the line passing through V and perpendicular to TU is:

y - 9 = (2/3)(x + 9)

Solving for x and y at the point where this line intersects TU, we get:

y = (2/3)x + 19

(2/3)x + 19 = -3x/2 + 7

x = -8/7

y = 94/21

The perpendicular distance from V to TU is the absolute value of y - 8:

|94/21 - 8| = 2/21

So, the area of triangle TUV is:

Area = 1/2 * TU * (2/21)

= (1/21)√(2)

To find the area of rectangle QRS, we need to find the length and width. We can use the distance formula to find the length QR and the width QS:

QR = √[(9 - (-8))² + (9 - 2)²]

= √[289]

= 17

QS = √[(9 - (-9))² + (2 - 2)²]

= √[324]

= 18

So, the area of rectangle QRS is:

Area = QR * QS

= 17 * 18

= 306

Area of triangle QRS = Area of rectangle QRS - Area of triangle TUV

= 306 - (1/21)√(2)

≈ 13.4 units

So, the answer is (C) 13.

Approximately 95% of scores lie between -1.96 and 1.96 z-scores. This is because the area under the standard normal distribution curve between these two values is approximately 0.95.

To calculate this, first calculate the area under the standard normal distribution curve between -1.96 and 1.96. This can be done by using a Z-score table, which provides the area under the curve to the left of a given value. To calculate the area between -1.96 and 1.96, subtract the area to the left of -1.96 from the area to the left of 1.96. This is approximately 0.95.

Since the total area under the curve is 1, this implies that approximately 95% of scores lie between -1.96 and 1.96 z-scores. This is commonly known as the "95% Rule," and it is a useful way to quickly estimate the amount of scores that are within a certain range.

It is important to note that this calculation is only an approximation, as the exact value depends on the actual values that are used. Therefore, it is important to use a Z-score table with more accurate values if more precision is needed.

Answer:

Step-by-step explanation:

To find g(4), we substitute x = 4 into the expression for g(x):

g(4) = -3(4) - 4 = -12 - 4 = -16

To find g(4) + 8, we add 8 to the value we just found for g(4):

g(4) + 8 = -16 + 8 = -8

Therefore, g(4) + 8 = -8.

6. f(x)g(x)+h(x) = 20x3-4x. This answer is arrived at by using the rules of algebra and the values of the given functions.

7. f(x)g(x) = -15x2 - 18x - 15

Polynomials are algebraic expressions consisting of variables and coefficients that are combined through addition, subtraction, multiplication and division operations. For example, the polynomial 4x² + 3x - 5 can be written as the sum of 4x², 3x and -5.

6. In order to calculate f(x) g(x)+h(x), it is necessary to first multiply f(x) and g(x). Since f(x)=4x and g(x) = 5x2-4, it follows that f(x)g(x)=20x3-4x. Next, it is necessary to add h(x) to this product. Since h(x) = 9x, it follows that f(x)g(x)+h(x) = 20x3-4x+9x = 20x3-4x. Since each coefficient is correctly represented in the answer, it follows that the correct answer is 20x3-4x.

Multiplying f(x) and g(x) gives the product of 20x3-4x, and adding h(x) to this product gives the sum of 20x3-4x. As each coefficient is correctly represented in the answer, the correct answer is 20x3-4x.

7. The product of two polynomials is found by multiplying each term of one polynomial by each term of the other polynomial. This is known as the FOIL method (First, Outer, Inner, Last).

The first term is the product of the first terms of each polynomial, which is 3x x 4x = 12x2.

The second term is the product of the outer terms, which is 3x x -5x = -15x2.

The third term is the product of the inner terms, which is 5 x -5x = -25x.

Finally, the fourth term is the product of the last terms of each polynomial, which is 5 x -3 = -15.

We can now combine the terms to get the product of the two polynomials, which is:

f(x)g(x) = -15x2 - 18x - 15.

Therefore, the correct coefficient for each term is -15x2 for the first term, -18x for the second term, and -15 for the third term.

Answer:30 gallons

Step-by-step explanation:

Answer:

30 gallons of tea

Step-by-step explanation:

Step 1:

First, before we do anything, let's convert 2 hours into minutes. There are 60 minutes in an hour, so we would multiply 60 and 2 to get 120 minutes.

Step 2:

Since we know that 4 cups of tea are poured every minute, we must multiply 4 by 120 because it is poured every 1 minute, and 4 × 120 = 480.

Step 3:

We also know that there are 16 cups of tea in one gallon, so we would divide 480 by 16 because we are trying to get how many gallons there are. 480 ÷ 16 = 30, so there are 30 gallons of tea poured in two hours.

Your gross pay per month including tips is $533.00. The answer is A) $533.00.

First, let's calculate your hourly wage including tips:

Hourly wage including tips = $6.75 + $3.50 = $10.25

Next, let's calculate your total earnings per week:

Total earnings per week = hourly wage including tips x hours worked per week

= $10.25 x 13 hours

= $133.25

Now let's calculate the deductions from your earnings:

FICA deduction = 7.56% x $133.25 = $10.08

Federal tax withholding = 9.6% x $133.25 = $12.80

State tax withholding = 6.7% x $133.25 = $8.92

Total deductions = $10.08 + $12.80 + $8.92 = $31.80

Finally, let's calculate your gross pay per month:

Gross pay per month = total earnings per week x 4 weeks - total deductions

= ($133.25 x 4) - $31.80

= $533.00

Therefore, your gross pay per month including tips is $533.00. The answer is A) $533.00.

In a sampling distribution of means, the distribution will approximate the normal distribution, the mean of the sampling distribution will equal the mean of the population and the standard deviation of the sampling distribution is based on Central Limit Theorem, option A.

The central limit theorem (CLT) of probability theory states that, under the assumption that all samples are of equal size and regardless of the population's actual distribution shape, the distribution of a sample variable approaches a normal distribution (i.e., a "bell curve") as the sample size increases.

In other words, the central limit theorem (CLT) is a statistical assumption that, given a sufficiently enough sample size from a population with a limited degree of variance, the mean of all sampled variables from the same population will be roughly equal to the mean of the entire population. According to the law of large numbers, these samples also resemble a normal distribution, with their variances almost equaling the variation of the population as the sample size increases.

The perimeter of a rectangle is equal to twice the length plus twice the width. Therefore, 18 cm = 2(length + 5) + 2(width). This equation can be solved by subtracting 2(width) from both sides, resulting in 18 - 2(width) = 2(length + 5). Finally, dividing both sides by 2 gives us 9 - width = length + 5. Therefore, width = 4 cm and length = 9 cm.

In this problem, we were given the perimeter of a rectangle, and asked to find its dimensions.

The problem provides two pieces of information about Hannah's jogging routine: she started with 3 41 miles and added 1/21 miles every week. We can use this information to create a linear equation that represents the number of miles Hannah jogged as a function of the number of weeks she has been jogging.

To create this equation, we first identify the starting value, which is 3 41 miles. This is also the y-intercept of the line. Next, we determine the slope of the line, which is the rate at which the number of miles increases each week. The slope is equal to the change in y (miles) divided by the change in x (weeks), which in this case is (1/21 - 3/41)/1 = -2/1 = -2. Therefore, the slope of the line is -2.

Putting these two pieces of information together, we get the equation y = -2x + 3 41, where y is the number of miles jogging and x is the number of weeks of jogging. This is a linear equation in slope-intercept form, where the slope is -2 and the y-intercept is 3 41.

This problem is a classic example of applying the stars and bars combinatorial method.

To solve this problem, we need to distribute 23 identical objects into 7 distinct containers so that none of the containers is empty. Let's start by assuming that each container has at least one object. This means we have distributed 7 objects, leaving 16 objects to be distributed.

We can now use the stars and bars method to distribute these 16 objects. Imagine placing all 16 objects in a line, and placing 6 dividers between them to separate them into 7 groups (one for each container). Each group will then receive the objects that are to the left of the divider.

For example, if we have the sequence OO|OOO|O|OOO|OO|OO|O, this corresponds to 2 objects in the first container, 3 objects in the second container, 1 object in the third container, and so on.

The number of ways to place the 6 dividers in the sequence of 16 objects is the same as the number of ways to choose 6 positions out of 16 to place the dividers. This can be computed using the formula for combinations:

$${16 \choose 6} = \frac{16!}{6!(16-6)!} = 8008$$

Therefore, there are 8008 ways to distribute 23 identical objects into 7 distinct containers so that no container is empty.
