which point from the equation would you use? y-7=3(x+9)
Answers
Another point on the line is (-9, 7). Ultimately, the choice of which point to use depends on the context or specific requirements of the problem you are solving.
To determine which point to use from the equation y - 7 = 3(x + 9), we need more information.
The equation provided represents a linear equation in the form y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.
Without additional context or specific instructions, we can choose any point that satisfies the equation to use as a reference.
For example, if we let x = 0, we can solve the equation for y:
y - 7 = 3(0 + 9)
y - 7 = 3(9)
y - 7 = 27
y = 27 + 7
y = 34
So, one point on the line is (0, 34).
Alternatively, if we let x = -9, we can solve the equation for y:
y - 7 = 3(-9 + 9)
y - 7 = 3(0)
y - 7 = 0
y = 7
So, another point on the line is (-9, 7).

Draw an angle in standard position with the given measure. 8/3 π
Answers
The asterisk (*) represents the vertex of the angle, the initial side is the positive x-axis, and the terminal side is the red line segment that forms an angle of 8/3 π with the positive x-axis.
What is the standard position of angles?
Standard position simply means that the vertex of the angle is at the origin of the circle and that one ray of the angle is on the positive x-axis. The other ray of the angle is placed at the angle measure formed by traveling counter-clockwise along the circle.
To draw an angle in standard position with measure 8/3 π, follow these steps:
Start with the positive x-axis.
Counterclockwise, rotate the initial side of the angle until it coincides with the positive x-axis.
Starting from the initial side on the positive x-axis, rotate the terminal side of the angle in a counterclockwise direction until the angle measures 8/3 π.
The resulting angle will have a measure of 8/3 π and will look like the following:

A technology company is going to issue new ID codes to its employees. Each code will have two letters, followed by one digit, followed by one letter. The letters D, G, and Z and the digit 8 will not be used. So, there are 23 letters and 9 digits that will be used. Assume that the letters can be repeated. How many employee ID codes can be generated?
Answers
Using the concept of permutation, the company can generate 108,927 different employee ID codes.
How many employee ID codes can be generated?To know the number of employee ID codes that's generated, we can check the number of possibilities of each component and multiply them together.
Given:
- Two letters can be chosen from 23 letters (excluding D, G, and Z).
- One digit can be chosen from 9 digits.
- One letter can be chosen from 23 letters (excluding D, G, and Z).
Number of possibilities for the first letter = 23
Number of possibilities for the second letter = 23
Number of possibilities for the digit = 9

Complete the square to make a perfect square trinomial. Then, write the result as a binomial squared. x2+3/2x
Answers
Answer:
The added term needed for that expression to be a square is 9/16.
Step-by-step explanation:
We're provided with two terms, and asked to add an additional term to make this a perfect square. For this to work, the term needs to be a scalar value that is the square of half the coefficient of the second term.
That coefficient is 3/2, so half of that is 3/4, and its square is 9/16.
If we tack that on the end then, we get:
\(x^2 + \frac{3x}{2} + \frac{9}{16}\\=(x + \frac{3}{4})^2\)
To confirm the answer, let's expand it and see if we get the original expression:
\((x + \frac{3}{4})^2\\= (x + \frac{3}{4})(x + \frac{3}{4})\\= x^1 + \frac{3x}{4} + \frac{3x}{4} + \frac{9}{16}\\= x^2 + \frac{6x}{4} + \frac{9}{16}\\=x^2 + \frac{3x}{2} + \frac{9}{16}\)
So 9/16ths is the scalar that needs to be added on the end.
A classic counting problem is to determine the number of different ways that the letters of "recommend " can be arranged.
Answers
The number of different ways that the letters of "recommend" can be arranged is 90720.
What is arrangement?
Generally speaking, an arrangement of objects is just a collection of them. A combination (order is ignored) or permutation is used to determine the number of "arrangements" of the components (order is significant). An arrangement is a group of hyperplanes that divides a space into cells.
If there are n different objects in the system then the number of different ways of arrangement of n objects is n!
If the repetition of the objects are allowed in the system the number of different ways of arrangement is -
n! / (no. of repetition of object 1)! .... (no. of repetition of object r)!
Total number of letters in the word "recommend is 9.
The number of different ways of arangement of the 9 letters is 91
The repetition of letter "e" is 2 and repetition of letter "m" is 2.
The number of different ways that the letters of "recommend" can be arranged is -
9! / 2! × 2!
(9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) / (2 × 1) × (2 × 1)
(9 × 8 × 7 × 6 × 5 × 3 × 2 × 1)

what is the probability that two cards chosen from an ordinary deck of 52 cards are both kings?
a. 1/15
b. 25/57
c. 25/ 256
d. None of the above
Answers
The probability that two cards chosen from an ordinary deck of 52 cards are both kings is d) None of the above.
There are 4 kings in a deck of 52 cards, so the probability of drawing one king from the deck is 4/52. Once a king has been drawn, there are only 3 kings left in the deck, and the total number of cards in the deck is reduced by one. So the probability of drawing a second king given that the first king has already been drawn is 3/51.
To find the probability of drawing two kings in a row, we need to multiply the probability of drawing the first king (4/52) by the probability of drawing the second king (3/51) given that the first king was drawn:
Probability of drawing two kings = (4/52) * (3/51) = 1/221
Therefore, the probability that two cards chosen from an ordinary deck of 52 cards are both kings is 1/221, which is not one of the options listed. Thus, the correct answer is option d) None of the above.

The ordering and transportation cost C for the c mponents used in manufacturing a product is c= 100(200/x^2+ x/x+30), x≥1 where C is measured in thousands of dollars and x is the order size in hundreds. Find the rate of change of C with respect to x when (a) x = 10, (b) x = 15, and (c) x = 20. What do these rates of change imply about increasing order size?
Answers
The ordering and transportation cost C for the components used in manufacturing a product is c= 100(200/x^2+ x/x+30), x≥1 where C is measured in thousands of dollars and x is the order size in hundreds.
To find the rate of change of C with respect to x when (a) x = 10, (b) x = 15, and (c) x = 20.
The rate of change of the cost with respect to x is its derivative.
The differentiation rules to apply are
Quotient Rule: \(\frac{d}{dx} \left[\frac{f(x)}{g(x)}\right] = \frac{g(x)f^{'}(x)-f(x)g^{'}(x)}{\left[g(x)]^{2} }\)
Constant Multiple Rule: \(\frac{d}{dx} \left[cf(x) \right] = cf^{'}(x)\)
Power Rule: \(\frac{d}{dx} \left[x^{n} \right] = nx^{n-1}\)
Constant Rule: \(\frac{d}{dx} [c] = 0\)
So,
\(c^{'}(x) = 100 (\frac{x^{2}(200)^{'}-200(x^{2})^{'}}{(x^{2})^{2} }+\frac{(x+30)(x)^{'}-x(x+30)^{'} }{(x+30)^{2} } )\)
\(c^{'}(x) = 100 (\frac{x^{2}(0)-200(2x) }{x^{4} } + \frac{(x+30)(1)-x(1+0)}{(x+30)^{2} })\)
\(c^{'}(x) = 100 (\frac{0-400x}{x^{4} } + \frac{x+30-x}{(x+30)^{2} })\)
\(c^{'}(x) = 100 (\frac{-400x}{x^{4} } + \frac{30}{(x+30)^{2} })\)
From the above values it appears that the rate of change of the cost increases as the size of the order increases
\(a) c^{'}(10) = -38.13\\ \\b) c^{'}(15) = -10.37\\ \\c) c^{'}(20) = -3.8\)
Hence the above values it appears that the rate of change of the cost increases as the size of the order increases

Answers
25% percent of the females in Math town have brown eyes. To find the number of females with brown eyes, we need to subtract the number of males with brown eyes from the total number of people with brown eyes
what is percent ?
A percent is a way of expressing a number as a fraction of 100. The symbol for percent is %, which means "per hundred".
In the given question,
Let's assume that there are 100 people in Math town.
60% of them are males, so there are 60 males and 40 females.
Out of the 60 males, 30% have brown eyes, so there are 18 males with brown eyes.
28% of the entire population have brown eyes, so there are 28 people with brown eyes.
To find the number of females with brown eyes, we need to subtract the number of males with brown eyes from the total number of people with brown eyes:
28 - 18 = 10
So, there are 10 females with brown eyes.
Out of the 40 females in Math town, what percentage have brown eyes?

Answers
The sampling method used by the restaurant manager allows for efficient data collection and a representative sample, it may introduce bias and lacks randomization.
Based on the information provided, we can identify the following statements that are true about the sampling method used by the restaurant manager to evaluate customer satisfaction with the new smoothie:
1. The manager uses systematic sampling: The manager surveys every other customer who orders the new smoothie. This systematic approach involves selecting every second customer, providing a consistent and organized sampling method.
2. The sample is representative: By surveying every other customer who orders the new smoothie, the manager ensures that the sample includes a variety of customers, reflecting the customer population as a whole.
3. The sample size may be smaller than the total customer base: Since the manager surveys every other customer, the sample size may be smaller compared to surveying every customer. This allows for efficient data collection and analysis.
4.The sampling method may introduce bias: The manager may inadvertently introduce bias by only surveying every other customer. Customers who are skipped in the survey may have different preferences or opinions, leading to a potential bias in the results.
5. The sampling method lacks randomization: Randomization is not employed in this sampling method, as the manager systematically selects customers. This could potentially introduce bias or exclude certain types of customers from the sample.

Answers
Using a standard normal distribution table, we find that the probability is approximately 0.0134 (rounded to four decimal places).
What is probability?Probability is a measure of the likelihood or chance that a particular event or outcome will occur. It is expressed as a value between 0 and 1, where 0 represents an event that is impossible to occur, and 1 represents an event that is certain to occur.
According to question:To solve this problem, we can use the formula for the standard deviation of the sample mean:
Standard deviation of sample mean = standard deviation / √(sample size)
Plugging in the given values:
Standard deviation of sample mean = 7 / √(31)
Next, we can calculate the z-score, which is the number of standard deviations the sample mean is below the population mean:
z-score = (sample mean - population mean) / standard deviation of sample mean
Plugging in the given values:
z-score = (141.5 - 145) / (7 / √(31))
Using a calculator, we find that the z-score is approximately -2.22.
Finally, we can use a standard normal distribution table or a calculator to find the probability that a z-score is less than -2.22.
Using a standard normal distribution table, we find that the probability is approximately 0.0134 (rounded to four decimal places).

Write the equation of the circle centered at (-4,4) with a diameter of 14.
Answers
To write the equation of a circle centered at (h, k) with a diameter of d, we can use the standard form of the equation:
(x - h)^2 + (y - k)^2 = r^2
where (h, k) represents the center of the circle and r represents the radius.
In this case, the center of the circle is (-4, 4), and the diameter is 14. The radius is half of the diameter, so the radius would be 14 / 2 = 7.
Substituting the values into the equation, we have:
(x - (-4))^2 + (y - 4)^2 = 7^2
Simplifying further:
(x + 4)^2 + (y - 4)^2 = 49
Therefore, the equation of the circle centered at (-4, 4) with a diameter of 14 is:
(x + 4)^2 + (y - 4)^2 = 49
