The answer to the equation cos195°cos285° is -1/4.

An equation is a mathematical statement that asserts the equality of two expressions. Equations are used to describe relationships between different quantities and can be used to solve for unknown values. Equations are typically written as symbols, but can also be written in words. Simple equations might involve addition, subtraction, multiplication, and division, while more complex equations may involve exponents, logarithms, and trigonometric functions. Equations can be used to model and understand real-world phenomena, such as calculating projectile motion, or predicting the behavior of a chemical reaction.

This is derived from the trigonometric identity cos{60°−x}cosx – sin(60°−x)sinx. This identity states that the cosine of the sum of two angles is equal to the product of the cosines of each angle minus the product of the sines of each angle.

By substituting the angles 195° and 285° into the identity, we get cos{60°−195°}cos195° – sin(60°−195°)sinx. When we use the values of the angles, we get cos{-135°}cos195° – sin(135°)sinx. We can then simplify this to -1/4cos195° – 0sinx. As the sine of the angle is 0, this simplifies to –1/4cos195°. As the cosine of 195° is -1/4, the answer to the equation cos195°cos285° is -1/4.

Plotting the data and visually examining the connection between x and y equation is often the best method for identifying which equation best describes the line of best fit.

A mathematical equation links two statements and utilises the equals sign (=) to indicate equality. In algebra, an equation is a mathematical assertion that proves the equality of two mathematical expressions.

Based on the above equations, y = x + 5 or y = x - 5 would be the most plausible contenders. Both of these equations have the typical slope for a linear connection, which is a straight line slope of 1.

While the y-intercept of the equation y = x + 15 has a significantly bigger value than would be predicted based on the other possibilities, the slope of the equation is 1. Similar to that, the slope of the equation y = 2x - 15 is 2.

The equation for the function shown in the given table is y = 4x + 2 OR 4x - y = -2. The graph of the equation is attached below

From the question, we are to determine the equation for the function

From the the given table,

When x = 0, y = 2

and when x = 1, y = 6

We can determine the equation for the function by using the formula,

(y - y₁)/(x - x₁) = (y₂ - y₁)/(x₂ - x₁)

From above

x₁ = 0

y₁ = 2

x₂ = 1

y₂ = 6

Thus,

(y - 2)/(x - 0) = (6 - 2)/(1 - 0)

(y - 2)/x = 4/1

1 × (y - 2) = 4 × x

y - 2 = 4x

y = 4x + 2

The solution to the set of equations is (x, y) = (8, 17).

What is system of linear equations?

A system of linear equations is a set of two or more equations with two or more variables that are to be solved simultaneously. Each equation in the system is linear, meaning it can be written in the form of ax + by + cz + ... = d, where a, b, c, and d are constants and x, y, z, and other variables are unknowns.

The goal of solving a system of linear equations is to find the values of the variables that satisfy all of the equations in the system. The solution of a system of linear equations is a set of values for the variables that make all of the equations true.

There are different methods to solve systems of linear equations, such as substitution method, elimination method, and matrix method. These methods involve manipulating the equations in the system to isolate one variable, substitute its value into another equation, and eventually find the values of all the variables.

Systems of linear equations are used in many areas of mathematics, science, engineering, and economics to model real-world situations and solve practical problems.

To find the solution to the set of equations, we need to determine the values of x and y that satisfy both equations simultaneously. One way to do this is to use substitution or elimination methods.

However, the given answer choices do not seem to be the steps of a solution process. We need to use both equations to find a solution. Here is one possible way to do it:

Equation S: y = x + 9

Equation T: y = 2x + 1

Since both equations equal to y, we can set them equal to each other:

x + 9 = 2x + 1

Simplifying this equation, we get:

x = 8

Now that we know the value of x, we can substitute it into either Equation S or Equation T to find the value of y. Let's use Equation S:

y = x + 9

y = 8 + 9

y = 17

Therefore, the solution to the set of equations is (x, y) = (8, 17).

None of the given answer choices matches this solution process.

To find the weight of each cookie, we need to know the total weight of the box of cookies. Let's call the weight of the box "W".

Since there are 16 servings in the box and each serving contains 4 cookies, there are a total of 16 x 4 = 64 cookies in the box.

To find the weight of each cookie, we can divide the total weight of the box by the number of cookies:

Weight of each cookie = W / 64

Without knowing the weight of the box, we cannot determine the weight of each cookie.

Step-by-step explanation:

v=4 or v=-1.

The given function is (3x^(3)-2x^(2)+3)/(x-1). To express it in the form q(x)+(r(x))/(b(x)), we need to use polynomial long division.

First, divide the first term of the numerator, 3x^(3), by the first term of the denominator, x:

3x^(3)/x = 3x^(2)

Now, multiply this result by the denominator and subtract it from the numerator:

(3x^(3)-2x^(2)+3) - (3x^(2)(x-1)) = -2x^(2)+3x^(2)-3

Simplify:

x^(2)-3

Next, divide the first term of the new numerator, x^(2), by the first term of the denominator, x:

x^(2)/x = x

Multiply this result by the denominator and subtract it from the new numerator:

(x^(2)-3) - (x(x-1)) = -3+x

Simplify:

x-3

Since the degree of the new numerator is less than the degree of the denominator, we can stop here. The final result is:

q(x) = 3x^(2)+x

r(x) = x-3

b(x) = x-1

So, the function can be expressed as:

(3x^(3)-2x^(2)+3)/(x-1) = 3x^(2)+x + (x-3)/(x-1)

The three points that divide the line segment joining the given points into four equal parts are \((3.5, -1.25)\), \((4, -1.5)\), and \((4.5, -1.75)\)

To find the three points that divide the line segment joining the given points into four equal parts, we can use the Midpoint Formula repeatedly. The Midpoint Formula is given by:

\[ \text{Midpoint} = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right) \]

Let's first find the midpoint of the given line segment:

\[ \text{Midpoint} = \left( \frac{3 + 5}{2}, \frac{-1 + (-2)}{2} \right) = \left( 4, -1.5 \right) \]

Now we can use the Midpoint Formula again to find the two other points that divide the line segment into four equal parts. Let's first find the midpoint of the line segment joining the points \((3, -1)\) and \((4, -1.5)\):

\[ \text{Midpoint} = \left( \frac{3 + 4}{2}, \frac{-1 + (-1.5)}{2} \right) = \left( 3.5, -1.25 \right) \]

And then let's find the midpoint of the line segment joining the points \((4, -1.5)\) and \((5, -2)\):

\[ \text{Midpoint} = \left( \frac{4 + 5}{2}, \frac{-1.5 + (-2)}{2} \right) = \left( 4.5, -1.75 \right) \]

Answer:

360 people pledged $25.

Step-by-step explanation:

You'll need to set up only one equation to solve this.

Let's use x for the number of people who pledged $50. Since twice as many people pledged $25, it would be 2x. Keep this in mind for later.

Multiply 2x by 25, and you should get 50x. Now, your equation is 50x + 50x = 18,000. Simplify this to 100x = 18,000.

Now, divide both sides by 100. After doing so, you should have x = 180. This is how many people pledged $50. To find how many pledged $25, plug the value of x into 2x. (In other words, multiply 180 by 2.) After doing so, you should get 360. This is how many people pledged $25.

Answer:

The 6.5% compounded annually would get you the most money. This is because, when compounded annually, the interest is calculated on the original sum plus the interest already earned. Over the four year period, this would result in total interest earned being higher than if the interest was compounded daily, as the interest earned each day would be calculated on the original sum only. For example, with a 6.5% compounded annually rate, at the end of the fourth year you would have a total of $127.82, whereas with a 6.3% compounded daily rate, you would have a total of $126.56

The solution set for the inequality 6x + 1 ≤ 4x + 1 is x ≤ -3/2 can be written in interval notation as (-∞, 0].

To solve the inequality 6x + 1 ≤ 4x + 1, we need to isolate the variable on one side of the inequality. Here are the steps to do so:

1. Subtract 4x from both sides of the inequality: 6x + 1 - 4x ≤ 4x + 1 - 4x
2. Simplify: 2x + 1 ≤ 1
3. Subtract 1 from both sides of the inequality: 2x + 1 - 1 ≤ 1 - 1
4. Simplify: 2x ≤ 0
5. Divide both sides of the inequality by 2: 2x/2 ≤ 0/2
6. Simplify: x ≤ 0
