We used the variable previously to show an angle in standard position, and we also referred to the sine and cosine functions as and . Often the sine and cosine functions are used in applications that have nothing to do with triangles or angles, and the letter x is used instead of for the input (as well as to label the horizontal axis). So from this point forward, we’ll refer to these same functions as and . This change does not affect the graphs; they remain the same. You know that the graphs of the sine and cosine functions have a pattern of hills and valleys that repeat. The length of this repeating pattern is . That is, the graph of (or) on the interval looks like the graph on the interval or or . This pattern continues in both directions forever. The graph below shows four repetitions of a pattern of length. Each one contains exactly one complete copy of the “hill and valley” pattern.

An example of an asset-producing debt

erastovalidia [21]

For example, education debt is a fact of life for many of us but we should view it as an investment in our future. We’d like to think it will provide us with an opportunity to increase our future income, so that makes it good debt. Debt for an unaffordable expensive car would be considered bad debt since it is an unnecessary expense that provides no income and depreciates in value. Debt for something that depreciates and provides no income would certainly be considered bad debt. An education is an investment that appreciates in value by increasing future income potential... the car is a depreciating expense that will provide no income and will rapidly depreciate in value (uses up income instead of providing income). The expensive car may be more fun to have, but the education will be the best investment.

Solve x2 + 2x + 9 = 0

Keith_Richards [23]

$x^2+2x+9=0 \\ \\
a=1 \\ b=2 \\ c=9 \\ b^2-4ac=2^2-4 \times 1 \times 9=4-36=-32 \\ \\
x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}=\frac{-2 \pm \sqrt{-32}}{2 \times 1}=\frac{-2 \pm \sqrt{-16 \times 2}}{2}=\frac{-2 \pm 4i\sqrt{2}}{2}=-1 \pm 2i\sqrt{2}$

The answer is D.

What ratio of height to width is considered most appropriate in graphing a frequency distribution?

Fiesta28 [93]

Answer:
As a rule of thumb, it is usual to define discrete data in 5 to 10 groups or bins. When graphed, the height of each group or bin defines the frequency for the group or bin.

Explanation:
When discrete data is graphed into a histogram, it defines a frequency distribution. Because information becomes lost when too many groups or bins are used, it is customary to use 5 to 10 bins.

Example:
Consider the following random data which has a sample size of 16.
x = [1, 3, 6, 2, 9, 8, 4, 5, 10, 3, 5, 4, 3, 5, 7, 5]
When fewer groups or bins are used to construct the histogram, the centralized nature of the distribution is easy to discern.
As the number of bins increases, the distribution becomes more difficult to define.
