A coterminal angle is an angle that has the same initial side and terminal side as a given angle. The difference between the angle and the coterminal angle is a multiple of 360 degrees.

The following steps can be used to find a coterminal angle between 0 and 360 degrees:

Step 1: Identify the given angle. Let's assume that the given angle is 100 degrees.

Step 2: Add or subtract multiples of 360 degrees to the given angle to obtain a new angle that has the same initial and terminal sides. To obtain the angle that is between 0 and 360 degrees, add or subtract 360 degrees from the angle until the result is between 0 and 360 degrees.There are two ways to do this.

The first method is to add or subtract multiples of 360 until the result is between 0 and 360 degrees. The second method is to divide the given angle by 360 degrees and then multiply the quotient by 360 degrees.

The first method:Subtract 360 degrees from 100 degrees to get -260 degrees. Add 360 degrees to -260 degrees to get 100 degrees, which is between 0 and 360 degrees. Therefore, 100 degrees and 460 degrees are coterminal angles between 0 and 360 degrees.

The second method:Divide 100 degrees by 360 degrees to get a quotient of 0.27777777778. Multiply 0.27777777778 by 360 degrees to obtain 100 degrees, which is between 0 and 360 degrees.

Therefore, 100 degrees and 460 degrees are coterminal angles between 0 and 360 degrees.

the point (3/8, -15/8, 0) on the plane z = 4x + 2y + 3 is closest to the origin. To find the point (x, y, z) on the plane z = 4x + 2y + 3 that is closest to the origin, we can use the concept of orthogonal projection.

The closest point will be the point on the plane that is closest to the origin, which is the orthogonal projection of the origin onto the plane.

First, we need to find the normal vector of the plane. The coefficients of x, y, and z in the equation of the plane give us the normal vector. So, the normal vector of the plane is (4, 2, -1).

Next, we need to find the projection of the origin onto the plane. The projection of a vector v onto a plane with normal vector n is given by the formula:

[tex]proj_n(v) = v - ((v . n) / ||n||^2) * n[/tex]

where "." denotes the dot product, "||n||" denotes the magnitude of the normal vector, and "proj_n(v)" denotes the projection of v onto the plane with normal vector n.

In this case, the vector v is the origin, which is (0, 0, 0), and the normal vector is (4, 2, -1). So, we can calculate the projection of the origin onto the plane as follows:

[tex]proj_n(v) = (0, 0, 0) - (((0, 0, 0) . (4, 2, -1)) / ||(4, 2, -1)||^2) * (4, 2, -1)[/tex]

= (0, 0, 0) - (0 / 21) * (4, 2, -1)

= (0, 0, 0)

Therefore, the projection of the origin onto the plane is the origin itself.

Finally, we can find the coordinates of the point on the plane that is closest to the origin by setting z = 0 in the equation of the plane:

0 = 4x + 2y + 3

Solving for y, we get:

y = (-2x - 3/2)

So, the coordinates of the point on the plane that is closest to the origin are:

x = 3/8

y = -15/8

z = 0

Therefore, the point (3/8, -15/8, 0) on the plane z = 4x + 2y + 3 is closest to the origin.

The equation of the line normal to the curve y=8tan(x2) at x=0.1825 is

=> y = 0.37985x + 7.4876.

To find the equation of the line normal to the curve y=8tan(x2) at x=0.1825, we need to find the derivative of the function first.

The derivative of y=(3x-cos2(x))4 is:

y'= 12(3x-cos2(x))3(3+2sin2(x))

At x=0.1825, the derivative of the function is

y'= 12(3*0.1825-cos2(0.1825))3(3+2sin2(0.1825))= 0.37985.

Now, the equation of the line normal to the curve at the given point (0.1825, 8tan(0.18252)) is given by:

y - 8tan(0.18252) = 0.37985(x - 0.1825).
Therefore, the equation of the line normal to the curve y=8tan(x2) at x=0.1825 is y = 0.37985x + 7.4876.

The probability of selecting red balls from a bag containing both red and blue balls is equal to the number of red balls divided by the total number of balls. In this example, let's assume there are 10 red balls and 10 blue balls, so the probability of selecting a red ball would be 10/20 or 1/2, or 50%.

To explain further, the probability is the likelihood of an event occurring and is expressed as a number between 0 and 1, or a percentage between 0% and 100%. A probability of 0 means the event will never happen, while a probability of 1 means it will always happen. The probability of selecting a red ball in this example is 50%, meaning that it is equally likely to select either a red ball or a blue ball.

In other words, if the bag contained 10 red balls and 10 blue balls and you randomly selected one ball from the bag, there is a 50% chance that the ball will be red and a 50% chance that the ball will be blue.

If the number of red balls or blue balls changes, the probability of selecting a red ball would also change. For example, if the bag contained 6 red balls and 10 blue balls, the probability of selecting a red ball would be 6/16 or 3/8, or 37.5%.

An equation is a mathematical statement that validates the equivalent of two expressions linked by the equal symbol '='. For example, 2x - 5 = 13. 2x-5 and 13 are two phrases. The character '=' is used to connect the two expressions. An equation is a mathematical formula that has two algebras on either side of an assignment operator (=). It illustrates the equivalency relationship between the left and middle formulas. In any formula, L.H.S. = R.H.S. (left side = right side).

We can begin by calculating the % price reduction for both the sweater and the jacket:

For the sweater, the percentage decrease is calculated as follows: (original price - reduced price) / original price * 100% = (100 - 80) / 100 * 100% = 20%

For the jacket, the initial price was $300, and the discounted price was $240.

(original price - reduced price) / (original price * 100%) = (300 - 240) / 300 * 100% = 20%

We can use the same percentage reduction to determine the lowered price of the $700 suit:

$700 was the original price.

% reduction = 20% decreased price = original price - % reduction / 100 * original price = $700 - 20 % reduction / 100 * $700 = $560

As a result, the $700 suit would sell for $560 during the sale.

Y= 5, then x = 20/3. We could also choose a different value of y and get a different value of x, but the sum of the areas of the rectangles will always be 30 square centimeters.

Rectangles are commonly found in architecture, engineering, and mathematics. They are used to model many real-world objects, such as doors, windows, computer screens, and paper. The shape and properties of a rectangle make it useful for many practical applications, such as calculating the area of a room or the size of a photo.

The diagonals of a rectangle are equal in length and bisect each other, forming two congruent right triangles. The length of the diagonals can be found using the Pythagorean theorem. The rectangle is also a special case of a rhombus, which has all four sides equal in length, and a square, which has all four sides equal in length and four right angles.

We know that the sum of the areas of the two rectangles is 30 square centimeters. We can use the formulas for the area of a rectangle to set up an equation:

Area of Rectangle 1 + Area of Rectangle 2 = 30

length * width + length * width = 30

Substituting the given values for the lengths of the rectangles:

3x + 2y = 30

This is a linear equation in two variables, x and y. We can solve for one variable in terms of the other:

3x = 30 - 2y

x = (30 - 2y)/3

This gives us the value of x in terms of y. We can substitute this expression for x into the equation above and solve for y:

3x + 2y = 30

3[(30 - 2y)/3] + 2y = 30

30 - 2y + 2y = 30

0 = 0

This equation is always true, which means that there are an infinite number of solutions. We can choose any value of y, and then use the expression for x in terms of y to find the corresponding value of x.

For example, let's choose y = 5. Then:

x = (30 - 2y)/3 = (30 - 10)/3 = 20/3

So, if y = 5, then x = 20/3. We could also choose a different value of y and get a different value of x, but the sum of the areas of the rectangles will always be 30 square centimeters.

Step-by-step explanation:

First I want to find the slope fo the line:

Between the points, the x value changes by 18 (-12 to 6) and the y value changes by -30 (26 to -4). To find slope we do rise/run so -30/18 is the slope. Simplified this is (-15/9) = (-5/3)

Next we should find the Y intercept:

The point (-12,26) is 12x away from the Y intercept line. Given the slope of -5/3, we know that for every 3x, the y level decreases by 5. Since 3 goes into 12 4 times, the y level decreases by 5*4 = 20 before it hits the y intercept. The previous y value for the point is 26 so 26-20 = 6. Y intercept is 6.

Plug into y=mx+b

The expression 8/9 - 5/6 in the simplest form is equal to 1/18. We got this value by getting common denominator and then subtracting.

What is denominator ?

The denominator is the bottom number in a fraction, and it represents the total number of equal parts that make up a whole. For example, in the fraction 3/5, the denominator is 5, which means that the whole is divided into 5 equal parts, and we are considering 3 of those parts.

To subtract fractions, we need to have a common denominator. In this case, the least common multiple (LCM) of the denominators 9 and 6 is 18. Therefore, we can rewrite the fractions with denominators of 18:

8/9 - 5/6 = (8/9) x (2/2) - (5/6) x (3/3)

= 16/18 - 15/18

Now that the fractions have a common denominator, we can subtract their numerators:
