To sketch the graph of a secant or cosecant function, first make a sketch of its corresponding cosine or sine function, respectively.
The secant function (sec(x)) is the reciprocal of the cosine function (cos(x)), while the cosecant function (csc(x)) is the reciprocal of the sine function (sin(x)). By graphing the corresponding cosine or sine function, we can identify the key features of the function such as the amplitude, period, and phase shift. These features will be reflected in the graph of the secant or cosecant function.
To obtain the graph of the secant function (sec(x)), we take the reciprocal of the y-values of the cosine function (cos(x)). Wherever the cosine function has a value of zero, the secant function will have a vertical asymptote. The secant function will have maximum and minimum points at the peak and trough points of the cosine function.
Similarly, to obtain the graph of the cosecant function (csc(x)), we take the reciprocal of the y-values of the sine function (sin(x)). Wherever the sine function has a value of zero, the cosecant function will have a vertical asymptote. The cosecant function will have maximum and minimum points at the peak and trough points of the sine function.

none of the above
The table has a greater rate of change.
The rates of change are equal.
In the given problem, we have a table showing the relationship between x and y values. By comparing the change in y with the change in x, we can determine the rate of change. Looking at the table, we observe that for every increase of 1 in x, there is a corresponding increase of 1 in y. Therefore, the rate of change for this table is 1.
The slopes are equal.
The equation has a greater slope.
In problem 2, we are given a linear equation in the form y = mx + b, where m represents the slope. The given equation is y = 2x + 7, which means the slope is 2. To compare the rates of change, we compare the slopes. If the slopes are equal, the rates of change are equal. In this case, the slopes are equal to 2, so the rates of change are the same.
The function rule has a greater slope.
The slopes are equal.
In problem 3, we are told that as x increases by 1, y increases by 3. This information gives us the rate of change between x and y. The slope of a function represents the rate of change, and in this case, the slope is 3. Comparing the slopes, we find that they are equal, as both have a value of 3. Therefore, the rates of change are the same.

November 2018, Perrigo had 91 million shares outstanding for a unit
price of 40 euros. Its Price to Book Ratio was 3.5. In addition,
Perrigo posted a net income of 166.4 million euros. What was its % financial profitability?
The answer based on the finance and share is financial profitability was 16%.
Given, shares outstanding = 91 million
Unit price = 40 euros
Price to book ratio = 3.5
Net income = 166.4 million euros
We know that the market capitalization of a company is given as:
Market capitalization = Share price x Shares outstanding
So, we can find the market capitalization of Perrigo as:
Market capitalization = 40 euros x 91 million= 3640 million euros
Now, we know that the price-to-book (P/B) ratio is given as:
Price-to-book ratio (P/B) = Market capitalization / Book value of equity
We can find the book value of equity as:
Book value of equity = Market capitalization / Price-to-book ratio= 3640 / 3.5= 1040 million euros
We can find the Return on Equity (ROE) as:
ROE = Net income / Book value of equity= 166.4 / 1040= 0.16 or 16%
Therefore, its % financial profitability was 16%.

If you have a right triangle with 36 square units. what is the scaled value if you go 2-1 , 3-1?
Answer:
324, 900, 9
Step-by-step explanation:
When a shape has its size increased by a scale factor, the size of its lengths are multiplied by this scale factor, yet its area is actually multiplied by the scale factor squared. This is due to two lengths being multiplied to contribute to the area, not just one. If it was a volume, you would multiply by the scale factor cubed!
Onto the answer, just follow the advice above:
36 * 3^2 = 36 * 9 = 324 square inches,
36 * 5^2 = 36 * 25 = 900 square inches,
36 * 0.5^2 = 36 * 0.25 = 9 square inches.

√(56-m)=m
explain like you are teaching me
Answer:
m = 7, -8
Step-by-step explanation:
√(56-m) = m
To remove the radical on the left side of the equation, square both sides of the equation.
\(\sqrt{(56-m)}\)² = m²
Simplify each side of the equation.
56 - m = m²
Now we solve for m
56 - m = m²
56 - m - m² = 0
We factor
- (m - 7) (m + 8) = 0
m - 7 = 0
m = 7
m + 8 = 0
m = -8
So, the answer is m = 7, -8
Answer:
√(56 - m) = m
Square both sides to clear the radical.
56 - m = m²
Add m to both sides, then subtract 56 from both sides.
m² + m - 56 = 0
Factor this quadratic equation.
(m - 7)(m + 8) = 0
Set each factor equal to zero, and solve for m.
m - 7 = 0 or m + 8 = 0
m = 7 or m = -8
Check each possible solution.
√(56 - 7) = 7--->√49 = 7 (true)
√(56 - (-8)) = -8--->√64 = -8 (false)
-8 is an extraneous solution, so the only solution of the given equation is 7.

My entire life I have noted the sun rises every morning and sets every evening. I am concluding that the sun will rise tomorrow morning and set tomorrow evening. Make an argument as to why this can be inductive or deductive reasoning and include details that indicate your knowledge of the topic.
The argument that the sun will rise tomorrow morning and set tomorrow evening is based on inductive reasoning, using past observations of consistent sunrise and sunset patterns to predict future occurrences.
1. The observation: Throughout your entire life, you have consistently noticed that the sun rises every morning and sets every evening. This is an observation based on personal experience.
2. Inductive reasoning: Based on this observation, you make an inference or prediction about the future. You reason that since the sun has always risen in the morning and set in the evening in the past, it is likely to continue doing so in the future.
3. Pattern and consistency: The assumption is that natural phenomena, such as the rising and setting of the sun, follow a pattern or regularity. This assumption is based on the principle of uniformity of nature, which suggests that the future will resemble the past in terms of natural occurrences.
4. The limitations of inductive reasoning: While inductive reasoning provides a useful way to make predictions based on past observations, it is not foolproof. There is always a small possibility that something unexpected could happen, such as a rare astronomical event or an external factor that alters the pattern. However, based on the available evidence and the consistency of the observed pattern, the prediction that the sun will rise tomorrow morning and set tomorrow evening is highly probable.
In summary, the argument relies on inductive reasoning, using the past consistent observation of the sun's rising and setting to predict that it will continue to do so in the future. While this reasoning is not infallible, it is a reasonable and practical way to make predictions based on observed patterns in nature.

To solve the problem we will calculate the cost of 1 sandwich first.
The cost of 12 sandwiches is 9.6 Rands.
Given
15 sandwiches are sold for 12 Rand
What is the value of 1 sandwich?We know the cost of 15 sandwiches is 12 Rand, therefore,

consider the following curve. y = 1 x 5 ex find y ′(x). y ′(x) = find an equation of the tangent line to the given curve at the point 0, 1 6 . y =
Equation of the tangent at (0, 1/7) is y = (5/36)x + 1/7.
To find an equation of the tangent line to the curve y = (1 + x)/(6 + \(e^{x}\) ) at the point (0, 1/7), we need to find the slope of the tangent line at that point and then use point-slope form to write the equation of the line.
To find the slope of the tangent line, we need to take the derivative of y with respect to x, and evaluate it at x = 0:
y' = [(6 + \(e^{x}\))(1) - (1 + x)( \(e^{x}\))]/\((6+e^{x} )^{2}\)
At x = 0, we have:
y' = [(6 + \(e^{0}\))(1) - (1 + 0)(\(e^{0}\))]/\((6+e^{0} )^{2}\) = 5/36
So, the slope of the tangent line at (0, 1/7) is 5/36.
Now, we can use point-slope form to write the equation of the tangent line:
y - \(y_{1}\) = m(x - \(x_{1}\))
where m is the slope we just found, and (\(x_{1}\), \(y_{1}\)) is the point we're given, (0, 1/7).
Substituting the values, we get:
y - 1/7 = (5/36)(x - 0)
Simplifying, we get:
y = (5/36)x + 1/7
Therefore, the equation of the tangent line to the curve y = (1 + x)/(6 + \(e^{x}\)) at the point (0, 1/7) is y = (5/36)x + 1/7.

Which of the following hold for all random variables X and Y?
A• Var (2X) = 4Var (X)
B• Var (X + 10) = Var (X)
C• Var (X + Y) = Var (X) + Var (Y)
D Var (3X + 3Y) = 9Var (X + Y)
Among the given options, the correct statement is: C. Var (X + Y) = Var (X) + Var (Y).
This statement is known as the addition rule for variance and holds true for all random variables X and Y, regardless of their specific distributions.
To understand why this statement is true, let's briefly discuss the concept of variance. Variance measures the dispersion or spread of a random variable's values around its expected value (mean). Mathematically, variance is defined as the average of the squared deviations of the random variable from its mean.
Now, let's prove statement C:
Var (X + Y) = E[(X + Y - E[X + Y])^2] (definition of variance)
= E[(X + Y - E[X] - E[Y])^2] (linearity of expectation)
Expanding the square term:
mathematica
Copy code
= E[(X - E[X])^2 + 2(X - E[X])(Y - E[Y]) + (Y - E[Y])^2]
By linearity of expectation, we can split this expression into three parts:
scss
Copy code
= E[(X - E[X])^2] + 2E[(X - E[X])(Y - E[Y])] + E[(Y - E[Y])^2]
= Var(X) + 2Cov(X, Y) + Var(Y) (definition of variance and covariance)
Note that Cov(X, Y) represents the covariance between X and Y, which measures the extent to which X and Y vary together. However, the given options do not mention anything about the covariance between X and Y, so we cannot determine its value.
Therefore, statement C is correct because it expresses the addition rule for variance, which states that the variance of the sum of two random variables is equal to the sum of their individual variances.
