The sound waves are illustrations of cosine functions

The frequencies of the sound waves are x = 90°, 120°, 240°, 270°

The equations of the sound waves are given as:

\(y = 2\cos^2(x)\)

\(y =-\cos(x)\)

Next, we plot the graphs of the functions \(y = 2\cos^2(x)\) and \(y =-\cos(x)\)

From the graphs of the functions (see attachment), we have the following x-coordinates of the points of intersection of the both curves between the interval [0°, 360°)

\(x =(\frac{\pi}{2},\frac{2\pi}{3},\frac{4\pi}{3},\frac{3\pi}{2})\)

Express as degrees

\(x =(90^o,120^o, 240^o, 270^o)\)

Hence, the frequencies of the sound waves are x = 90°, 120°, 240°, 270°

Step-by-step explanation:

The closer together the points are to a line that can be drawn, the stronger the association.

1.  weak is B, the points are all over the place and a clear line can't even be drawn

2.  moderate is A, if you drew a line between the points, a line can be drawn and they points are somewhat close to the line

3. strong is C because you can draw a line through points are they are pretty closely clustered near the line.

FIFO - March cost of goods sold = $13,050. March 31 inventory = $7,350. LIFO - March cost of goods sold = $14,600. March 31 inventory = $5,800.

To calculate March cost of goods sold we need to add the given data for FIFO =

March cost of goods sold

= (2,800 + 3,700 + 6,550)

= 13,050

To calculate March cost of goods sold we need to add the given data for LIFO =

March cost of goods sold

= (3,400 + 4,400 + 6,800)

= 5,800

H 75 + Q > or = 120

Answer:

It's option B, (f • g)(x) = 3x^3 + 6x^2 - 5x - 10

Step-by-step explanation:

In this problem, we are dealing with a branch of functions called composite functions. What the difference is between normal and composite functions is that we instead of defining a value for f(x), take two functions, f(x) and g(x), in the form of f and g. For instance, h(x) = g.

• Take the products of both functions.

f(x)g(x) = 3x²+5 • x-2

• Next, expand the functions. We expand by combining like terms.

= 3x^3 - 6x^2 + 5x - 10

Since the function cannot be simplified further, this leads to option B being our answer.

Hope this helps!

The best description of the graph is option B) It is a line which intersects the y-axis at (2, 2). This is because the line has a y-intercept of 2 and intersects the y-axis at the point (0, 2). Option B

To determine the best description of the graph of the equation x + y = 2, we can rearrange the equation into slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.

Rearranging the equation, we have:

y = -x + 2

From this equation, we can see that the slope is -1, meaning that for every unit increase in x, y decreases by 1. The y-intercept is 2, indicating that the line intersects the y-axis at the point (0, 2).

Therefore, the best description of the graph is option B) It is a line which intersects the y-axis at (2, 2). This is because the line has a y-intercept of 2 and intersects the y-axis at the point (0, 2).

Option A) It is a line which intersects the x-axis at (2, 2) is incorrect because the line intersects the x-axis at the point (2, 0), not (2, 2).

Option C) It is a line joining the points whose x- and y-coordinates add up to 2 is incorrect because the equation represents a line and not a set of points.

Option D) It is a line joining the points whose x- and y-coordinates add up to 4 is incorrect because the equation represents a line where the x- and y-coordinates add up to 2, not 4.

Given that the lengths from the center to either chords are equal

This means that

FE = 6 units

For the other circle, we have

BC = 58 degrees

AB = ED

The arc AE is calculated as

AE = 180 - BC - ED

Where

AB = ED = BC = 58 degrees

y = -1/5x +1/2 linear function has the same slope .

A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all. Any two different points on a line can be used to calculate the slope of any line. The ratio of "vertical change" to "horizontal change" between two different locations on a line is calculated using the slope of a line formula. We shall comprehend the slope-finding method and its applications in this essay.

First solve for the slope

m =\(\frac{y_{2} -y_{1} }{x_{2} -x_{1} }\)

m=\(\frac{0-\frac{3}{5} }{\frac{1}{2} -\frac{1}{5} }\)

m = \(\frac{-1}{5}\)

Look for the linear equation with the same value of m after determining the slope (parallel equation).

Answer:

Step-by-step explanation:

For normal distribution z score is

=  \(\frac{\hat p-p}{\sigma p}\)

Population proportion (p) = 0.060

Sample size (n) = 285

the standard error of proportion is

=  \(\sigma p = \sqrt{\frac{p\times (1 - p)}{n}}\)

After putting the values into the above formula we will get

= 0.0141

Probability as the sample proportion will different from the population proportion by lower than the 4% that is

Probability = P(0.02<X<0.1) = P(-2.84<Z<2.84) = 0.9977 - 0.0023

The graph would show two lines, one for Tom and one for Steve. Tom's line would be a straight, continuous line with a positive slope representing a constant speed of 80 km/h.

Graph is a mathematical structure used to depict relationships among objects. It consists of a set of objects, known as vertices, connected by edges. A graph can represent any kind of relationship between two or more objects, such as a flowchart, a map, or a family tree. Graphs are widely used in computer science, engineering, and mathematics to represent data and solve problems.

Steve's line would start as a straight, continuous line with a positive slope representing a constant speed of 100 km/h. At d = 150, the line would have a break representing the 30-minute rest and then continue on with a positive slope, representing Steve's continued journey at the constant speed of 100 km/h.

Answer:

(x + 2)² + (y + 2)² = 0.75²

Step-by-step explanation:

Standard form

(x - h)² + (y - k)² = r²

the center is (h, k) = (-2, -2)

the radius is r = 0.75

(x + 2)² + (y + 2)² = 0.75²

Answer:

(x + 2)^2 + (y + 2)^2 = 0.5625

Step-by-step explanation:

By looking at the graph, we can see the center of the circle is (-2, -2) and by counting the squares, the radius is 0.75.

The standard form of a circle equation is:

(x - h)^2 + (y - k)^2 = r^2

where (h, k) is the center and r is the radius.

We can substitute our values in to get:

(x + 2)^2 + (y + 2)^2 = 0.5625
