The parent function f(x) = x² was reflected over the x-axis and translated three units left and two units down to form y = g(x). The function g(x) = - (x + 3)² - 2. is the correct anwer.

Here, the given parent function is f(x) = x².

We need to find the equation for the function g(x) which is obtained by reflecting the parent function f(x) = x² over the x-axis and translating it to three units left and two units down.

Therefore, the reflection of the parent function f(x) = x² over the x-axis gives the function h(x) = -x².

This function is obtained by negating all the y-coordinates of the parent function.

Then, we need to translate this function with three units left and two units down to obtain the function g(x).

Hence, the function g(x) = - (x + 3)² - 2.

Here, we obtain the desired equation for the function g(x) which is obtained by reflecting the parent function f(x) = x² over the x-axis and translating it to three units left and two units down.

Answer:

100+4.50(s)+12(s)+96⩽ 800

s=students

they can spend up to 800 dollars OR LESS. They have a charge of 100 dollars for the bus, plus a charge of 4.50 per student for lunches, plus a charge of 12 dollars per student for admissions plus 16 dollars times 6 (96) for the chaperones. All of this gives us our inequality above.

PS: the reason why the adults don't get their own variable is because it says to define the variable not variable(s). You also cannot group the adults with the students because the student costs and the adult costs are two totally seperate and different amounts. if you just used variable p for people it wouldn't work because you wouldn't know how many adults were required to pay adult admission.

Based on the given information, we have the mean concentration of sodium in the drinking water of a water system in Connecticut as 26.4 mg/l and the standard deviation as 6 mg/l.

The water department selects a simple random sample of 32 water specimens over the course of a year. To answer the question using the distributions tool, we need to set the mean and standard deviation parameters on the tool to the expected mean and standard error for the distribution of sample mean concentrations.

The expected mean for the distribution of sample mean concentrations is the same as the mean concentration of sodium in the drinking water, which is 26.4 mg/l.

The water department in Connecticut is monitoring the concentration of sodium in their drinking water. By calculating the mean and standard error for the distribution of sample means, they can determine the probability of the mean concentration exceeding the notification level of 28 mg/l. If this probability is low, the water department will notify the public and recommend necessary actions.

In this scenario, the water department in Connecticut wants to monitor the concentration of sodium in their drinking water. They have set a notification level of 28 mg/l, meaning that if the mean concentration of sodium across a sample of 32 water specimens exceeds this level, they will notify the public.

To analyze this situation, we can use the distribution of sample means. The mean concentration of sodium in the drinking water of the water system is given as 26.4 mg/l, with a standard deviation of 6 mg/l.

To find the expected mean and standard error for the distribution of sample means, we can use the following formulas:

Expected mean of sample means = population mean

                                                        = 26.4 mg/l
Standard error of sample means = population standard deviation / square root of sample size

Using the given values, the standard error of sample means can be calculated as follows:
Standard error of sample means = 6 mg/l / square root of 32

                                                      ≈ 1.06 mg/l

Now, we can use a distributions tool to find the probability that the mean concentration of sodium in the sample of 32 water specimens exceeds 28 mg/l. We will set the mean parameter on the tool to 26.4 mg/l and the standard deviation parameter to 1.06 mg/l.

By entering these values into the distributions tool, we can find the probability of obtaining a mean concentration greater than 28 mg/l. If this probability is less than a certain threshold (e.g., 0.05), it indicates that the mean concentration exceeding 28 mg/l is unlikely to occur by chance alone. In such cases, the water department would notify the public and recommend that individuals on sodium-restricted diets inform their physicians of the sodium content in their drinking water.

The value of the number is 135

Let 'm' be the required number.

We have been given a statement '12 less than four fifths of a number is three fifths of number increased by 15.'

We write given statement as a mathematical expression.

We can write '12 less than four fifths of a number ' as,

(4/5)m - 12

Also, we can write 'three fifths of number increased by 15' as (3/5)m + 15

so for statement, '12 less than four fifths of a number is three fifths of number increased by 15' we get an equation,

(4/5)m - 12 = (3/5)m + 15

Now we solve above equation to find the value of the m.

⇒ (4/5)m - 12 = (3/5)m + 15

⇒ (4/5)m - (3/5)m = 15 + 12

⇒ (4/5 - 3/5)m = 27

⇒ (1/5)m = 27

⇒ m = 27 × 5

⇒ m = 135

The solution of the given problem of triangle comes out to be tan ∠A = 0.25.

Triangles are called polygons if they have four quadrants or more. Its form is a simple geometric figure. When put together, the characters ABC create a right-angled triangle. When the boundaries are incompatible, Euclidean geometry generates a new rectangle with square corners. Triangles are regarded as polygons because they have three edges and three corners.

Here,

Since △ABC is a right triangle with m∠C = 90°, we know that m∠A + m∠B = 90°.

Using the fact that tan ∠B = opposite/adjacent, we can set up a ratio using a common factor, x, for the opposite and adjacent sides of ∠B:

tan ∠B = 0.25 = opposite/adjacent = x/4x

Simplifying the right side, we get:

0.25 = x/4x = 1/4

Multiplying both sides by 4x, we get:

x = 4

So the opposite side of ∠B has length x = 4, and the adjacent side has length 4x = 16.

Using the Pythagorean theorem, we can find the length of the hypotenuse of △ABC:

c² = a² + b²

c² = 4²+ 16²

c² = 256

c = √256

c = 16

Now, we can use the fact that tan ∠A = opposite/adjacent to find tan ∠A:

tan ∠A = opposite/hypotenuse = 4/16 = 1/4

Therefore, tan ∠A = 0.25.

To show that the given equations represent trigonometric identity statements, we will simplify each equation and demonstrate that both sides of the equation are equal.

Starting with sec²θ(1 - cos²θ):

Using the Pythagorean identity sin²θ + cos²θ = 1, we can rewrite sec²θ as 1 + tan²θ. Substituting this into the equation, we get:

(1 + tan²θ)(1 - cos²θ)

= 1 - cos²θ + tan²θ - cos²θtan²θ

= 1 - cos²θ(1 - tan²θ)

= sin²θ

Thus, the equation simplifies to sin²θ, which is a trigonometric identity.

For cosx(secx - cosx) = sin²x:

Using the reciprocal identities secx = 1/cosx and tanx = sinx/cosx, we can rewrite the equation as:

cosx(1/cosx - cosx)

= cosx/cosx - cos²x

= 1 - cos²x

= sin²x

Hence, the equation simplifies to sin²x, which is a trigonometric identity.

Considering cosθ + sinθtanθ = secθ:

Dividing both sides of the equation by cosθ, we obtain:

1 + sinθ/cosθ = 1/cosθ

Using the identity tanθ = sinθ/cosθ, the equation becomes:

1 + tanθ = secθ

This is a well-known trigonometric identity, where the left side is equal to the reciprocal of the right side.

Simplifying (1 - cos∝)(cosec∝ + cot∝):

Expanding the expression, we have:

cosec∝ - cos∝cosec∝ + cot∝ - cos∝cot∝

= cot∝ - cos∝cot∝ + cosec∝ - cos∝cosec∝

= cot∝(1 - cos∝) + cosec∝(1 - cos∝)

= cot∝tan∝ + cosec∝sec∝

= 1 + 1

= 2

Thus, the equation simplifies to 2, which is a constant value.

In summary, we have analytically shown that the given equations represent trigonometric identity statements by simplifying each equation and demonstrating that both sides are equal.

Since opposite angles of a parallelogram are equal, angle A = angle C and angle B = angle D where x is 35.

What is parallelogram?

A parallelogram is a four-sided flat shape in which opposite sides are parallel and have the same length. It is a type of quadrilateral, which means it has four sides.

The opposite angles of a parallelogram are also equal, which means that if angle A is equal to angle C, then angle B is equal to angle D. Moreover, the adjacent angles of a parallelogram are supplementary, which means that if angle A and angle B are adjacent angles, then angle A + angle B = 180 degrees.

According to the question:
Since AB = CD and angle A is 60 degrees, it means that opposite sides AB and CD are parallel and have the same length. Therefore, the figure ABCD is a parallelogram.

To determine the value of angle B, we can use the fact that the opposite angles in a parallelogram are equal. That is, angle B = angle D.

Since angle A + angle B + angle C + angle D = 360 degrees for any quadrilateral, we can write:

angle A + angle B + angle C + angle D = 60 + (3x+15) + angle C + angle D = 360

Simplifying this equation, we get:

4x + 75 + angle C + angle D = 360

angle C + angle D = 360 - 4x - 75 = 285 - 4x

Since angle B = angle D, we have:

angle B + angle D = 2 angle D = (3x+15)

Therefore, we can solve for angle D:

2 angle D = (3x+15)

angle D = (3x+15)/2

Now, we can substitute this into the equation for angle C + angle D:

angle C + (3x+15)/2 = 285 - 4x

Multiplying both sides by 2, we get:

2 angle C + 3x + 15 = 570 - 8x

Simplifying and solving for angle C, we get:

2 angle C = 555 - 11x

angle C = (555 - 11x)/2

Therefore, the angles of the parallelogram ABCD are:

angle A = 60 degrees

angle B = (3x+15) degrees

angle C = (555 - 11x)/2 degrees

angle D = (3x+15)/2 degrees

Note that since opposite angles of a parallelogram are equal, angle A = angle C and angle B = angle D.

The Bayes' decision rule strategy is Buy.

Bayes' decision rule is used to choose between a set of mutually exclusive and collectively exhaustive outcomes based on the probabilities of those outcomes and their expenses. It chooses the decision alternative with the largest expected value. Bayes' decision rule specifies the following method for selecting between two mutually exclusive possibilities:

choose the one with the highest probability of being correct. Suppose we have two alternatives, A1 and A2, and we must select one. The outcomes O1, O2, and O3 may arise if we select A1, and outcomes O4, O5, and O6 may arise if we select A2, as shown in the given payoff table below:O1 O2 O3A1 r1 r2 r3A2 r4 r5 r6The procedure for using Bayes' rule is as follows:

Step 1: Calculate the likelihood ratios for each outcome. The likelihood ratio is the probability of the outcome given the chosen alternative divided by the probability of the outcome given the alternative not selected. For example, the likelihood ratio for O1 is as follows: r1/(r4 + r5 + r6).

Step 2: Estimate the prior probabilities of the alternatives (before any information is acquired). Assume that these are 50-50 probabilities unless more information is available. For example, if A1 and A2 are equally likely, their prior probabilities are both 0.50.

Step 3: Calculate the posterior probabilities of the alternatives given the observed outcome.

Bayes' theorem is used to calculate the posterior probabilities of the alternatives. The formula for Bayes' theorem is as follows: P(Ai|Oj) = (P(Oj|Ai)P(Ai))/ P(Oj)where P(Ai|Oj) is the posterior probability of Ai given Oj, P(Oj|Ai) is the likelihood of Oj given Ai, P(Ai) is the prior probability of Ai, and P(Oj) is the total probability of Oj, which is the sum of the likelihoods for the two alternatives.

10 + 2x = 15 + x

Taking x away from both sides:

10 = 15 - x

x = 5

Thus, Greg and Savannah will have the same number of books in their libraries after five weeks. By substituting x = 5 into either equation, we can determine how many books that is:

Given that a company's vice president's salary n years after becoming vice president is defined by the formula S(n) = 70000(1.2)". We have to determine which of the following statements is true:

She will be receiving a 2% raise per year. Her salary will increase $14,000 every year. The percent increase of her salary is 120% every year. Her salary is always 0.2 times the previous year's salary. The percent increase of her salary is 20% every year.

To calculate the salary of the vice president after n years of becoming a vice president, we use the given formula:

S(n) = 70000(1.2)

S(n) = 84000

The salary of the vice president after one year of becoming a vice president: S(1) = 70000(1.2)

S(n) - S(n-1) / S(n-1) × 100%

S(n) - S(n-1) / S(n-1) × 100% = (70000(1.2)n) - (70000(1.2)n-1) / (70000(1.2)n-1) × 100%
