General information

All of these questions have to do with various translations of the square root function. The first problem deals with the basic function. Other problems translate the graph in various ways.

The basic square root function has its vertex at (0, 0) and is defined for x-values (domain) that are 0 or positive. The resulting y-values (range) are also zero or positive.

The basic function intercepts the x- and y-axes only at the point (0, 0), so both intercepts are 0. Unless the function is reflected vertically or horizontally, its minimum will be at the left end of any interval, and its maximum will be at the right end.

The transformation of a function g(x) to f(x) = g(x -a) +b causes it to be translated 'a' units to the right and 'b' units up. For the functions here, that means the vertex is translated from (0, 0) to (a, b). For the functions here, the vertex values are the limits of the domain and range, so those will be altered accordingly.

Problems

1.

a) The graph is shown in the attachment as f1 (orange).

b) vertex: (0, 0); domain: [0, ∞); range: [0, ∞)

c) x-intercept: 0; y-intercept: 0

d) On the interval [1, 4], the minimum is √1 = 1, and the maximum is √4 = 2.

__

2.

a) The graph is shown in the attachment as f2 (green). The basic function is translated left 1 and down 2.

b) vertex: (-1, -2); domain: [-1, ∞); range: [-2, ∞)

c) x-intercept: 3; y-intercept: -1 (read from the graph)

d) On the interval, [0.5, 5], the minimum is √1.5 -2 ≈ -0.78; the maximum is √6 -2 ≈ 0.45. Min and max values are shown in the table in the second attachment.

__

3.

a) The graph is shown in the attachment as f3 (purple). The basic function is translated up 3.

b) vertex: (0, 3); domain: [0, ∞); range: [3, ∞)

c) x-intercept: (none); y-intercept: 3 (the vertex)

d) On the interval, [2, 4], the minimum is √2 +3 ≈ 4.41; the maximum is √4 +3 ≈ 5. Min and max values are shown in the table in the third attachment.

__

4.

a) The graph is shown in the attachment as f4 (red). The leading multiplier of -2 causes the graph to be reflected over the x-axis and vertically expanded by a factor of 2 before being translated right 2 and up 3.

b) vertex: (2, 3); domain: [2, ∞); range: (-∞, 3]. Note the range is all y-values less than or equal to 3 because of the vertical reflection.

c) x-intercept: 4.25; y-intercept: (none). The x-intercept is found by solving ...

  0 = -2√(x -2) +3

  (-3/-2)² = x-2

  2 +2.25 = x = 4.25

d) On the interval, [4, 7], the minimum is -2√(7 -2)+3 = 3-2√5 ≈ -1.47; the maximum is -2√(4-2)+3 = 3-2√2 ≈ 0.17. Min and max values are shown in the table in the second attachment.

The goal of our sampling is to determine the favorite sport of the students in the high school. For that we need to sample from all the students in the school, trying to get as diversified as possible. Let's analyze each strategy and choose the better one.

Kenneth goes to a football field, since he's already at an sports event, most of the students going there will have football as their favorite sport, skewing the data towards that. Therefore this is not an effective strategy.

Lynn stands at the entrance of the school sampling 20 students that arrives, this also doesn't take a lot of students into account, because most of the people that arrive early presumably have a simillar personality.

Maleka uses a list of students from the whole scools, then chooses at random the names she'll interview. This seems like a good approach, because it's from the whole school, and there isn't a significant bias inserted into the sampling.

Finally tony samples all the students from his class, this also does not sound like a good strategy, because they don't represent the whole school.

The best strategy is the one used by Maleka, option C.

Step-by-step explanation:

The number c that satisfies the conclusion of the Mean Value Theorem for the function f(x) = x + 3/x on the interval [1, 14] is approximately c = 3.75.

To find the number c that satisfies the conclusion of the Mean Value Theorem for the function f(x) = x + 3/x on the interval [1, 14], follow these steps:

1. Verify the conditions of the Mean Value Theorem:
  The function f(x) = x + 3/x is continuous on the closed interval [1, 14] and differentiable on the open interval (1, 14).

2. Calculate the average rate of change of the function on the interval:
  f(14) = 14 + 3/14 ≈ 14.214
  f(1) = 1 + 3/1 = 4
  Average rate of change = (f(14) - f(1)) / (14 - 1) ≈ (14.214 - 4) / 13 ≈ 0.786

3. Differentiate the function to find the instantaneous rate of change:
  f'(x) = 1 - 3/x²

4. Set f'(x) equal to the average rate of change and solve for x:
  1 - 3/x² = 0.786
  x² = 3 / (1 - 0.786)
  x² ≈ 14.056
  x ≈ √14.056 ≈ 3.75

The number c that satisfies the conclusion of the Mean Value Theorem for the function f(x) = x + 3/x on the interval [1, 14] is approximately c = 3.75.

This calculator computes the mean absolute deviation from a data set:

You do not need to specify whether the data is for an entire population or from a sample. Just type or paste all observed values in the box above. Values must be numeric and may be separated by commas, spaces or new-line. Press the "Submit Data" button to perform the computation. To clear the calculator, press "Reset".

What is the mean absolute deviation

The mean deviation is a measure of dispersion, A measure of by how much the values in the data set are likely to differ from their mean. The absolute value is used to avoid deviations with opposite signs cancelling each other out.

Mean absolute deviation formula

This calculator uses the following formula for calculating the mean absolute deviation:

$ MAD =\frac{1}{n} \sum_{i=1}^n |x_i-\bar{x}|$

where n is the number of observed values, x-bar is the mean of the observed values and xi are the individual values.

To find the percentage rate of change of a function at a specific point, we need to find the derivative of the function. The percentage rate of change of f(t) = e^-0.09t^2 at t=1 and t=5 is approximately -17.75% and -13.65%, respectively.

To find the percentage rate of change of a function at a specific point, we need to find the derivative of the function at that point and then multiply it by 100%. Thus, the derivative of f(t) is given by:

f(t)=e^-0.09t^2

f'(t) = (-0.18t)e^(-0.09t^2)

Evaluating f'(1) and f'(5) yields:

f'(1) = (-0.18)(1)e^(-0.09(1)^2) ≈ -0.1606

f'(5) = (-0.18)(5)e^(-0.09(5)^2) ≈ -0.1851

To find the percentage rate of change, we multiply the derivative by 100% and divide by the function value at the respective point:

Percentage rate of change at t=1:

= (f'(1)/f(1)) * 100%

= (-0.1606/e^-0.09) * 100%

≈ -17.75%

Percentage rate of change at t=5:

= (f'(5)/f(5)) * 100%

= (-0.1851/e^-0.09) * 100%

≈ -13.65%

Therefore, the percentage rate of change of f(t) at t=1 and t=5 is approximately -17.75% and -13.65%, respectively.

For a set population, a parameter does not change. A parameter is a numerical value that describes some aspect of a population, such as the mean, median, or standard deviation.

It is a fixed value that represents the entire population and does not change as new data is collected.

If there are three different samples of the same size from a set population, it is possible to get three different values for the same statistic.

Because a sample is a subset of a population, the values of statistics calculated from samples will vary depending on the specific individuals or observations that are included in the sample. Even if the samples are of the same size, they will likely have different values for the statistics because of the randomness of sampling.

If she can reuse her shorts and shirts:

Day 1: one short, one shirt, and one pair of shoes. (Well, this leaves her with one shirt and two pairs of shoes.)

Day 2: one short, one shirt, and one pair of shoes. (This is the thinking that she can reuse her clothing. Now, she is left with one pair of shoes.)

Day 3: one short, one shirt, and one pair of shoes. (Also thinking she can reuse clothing. Now she has completely used all her shorts, shirts, and shoes.

If she can't reuse:

Day 1: one short, one shirt, and one pair of shoes. However, now she is left with one shirt and two pairs of shoes that she didn't use because she can't reuse the shorts.

In conclusion, if she can reuse the shorts and shirts, she will have three different combinations. If she can't reuse them, she will have one outfit combination.

6x-y=2 is the equation

Step-by-step explanation:

The formula is y= mx+c where m= slope and c = y-intercept

so replacing their values,

y = 6x -2

y+2= 6x

6x-y = 2 is the required equation.

Answer:

y=6x-2

Step-by-step explanation:

Answer: to write an equation it has to be y=mx+b

The slope is 6, so you substitute the 6 in for the m. M is always the slope.

You also keep the x there.

The y intercept, also know as b, is -2 so you substitute that in for b.

Then you get the equation on the line.

Supply and demand are two factors that affect how much a country's currency is worth.

The supply and demand of a country's currency determine the value of that currency in a free-floating currency exchange market. A currency improves in value or appreciates when demand for it rises. A currency loses value or depreciates when there is less demand for it.

Money's demand determines how much it is worth. When there is still a strong demand for treasuries, the US dollar increases. The value of a currency determines both its supply and demand. For instance, if a nation prints a lot of currency, the value relative to other currencies will drop because supply exceeds demand. Inflation will happen if the cost of products rises or the value of money declines in comparison to other assets.

By answering the presented question, we may conclude that So the arithmetic mean of (3a-2) and (5a-6) is: ((3a-2) + (5a-6))/2 = 4a-4

The mean of a dataset is the sum of all values divided by the total number of values; this is also known as the arithmetic mean (as opposed to the geometric mean). This is the most often used measure of central tendency, sometimes known as the "mean." Merely dividing the entire number of values in the dataset by the sum of those values provides this result. Calculations may be performed using both raw data and data that has been compiled into frequency tables. The average of a number is referred to as its average. It is simple to calculate: Divide the total number of digits by the number of digits. the sum divided by the count.

The arithmetic mean of two numbers is the sum of the numbers divided by 2.

The arithmetic mean of (3a-2) and (y) can be expressed as:

(3a-2 + y)/2

(3a-2 + y)/2 = 4a-4

3a-2 + y = 8a-8

y = 5a-6

Therefore, the value of x is 5a-6.

So the arithmetic mean of (3a-2) and (5a-6) is:

((3a-2) + (5a-6))/2 = 4a-4

And this is consistent with our initial equation.
