What is 3/18 written in simplest form? Explain how you found you answer.

The factored form of the equation is g(x) = -(x + 2)(x − 4)..

A quadratic expression that is written as the product of a constant times two linear factors is said to be in factored form.

Given:

As, the equation of the function in factored form,

g(x) = a(x − [tex]r_1[/tex])(x − [tex]r_2[/tex]),

The function has x-intercepts of -2 and 4.

So (x + 2 )and (x − 4) are factors of the equation.

Now, the value of y changes for 1 unit to the right of the vertex.

The y-value goes down 1 unit for a point 1 unit to the right of the vertex, so a = -1.

So, the equation of this quadratic function is

g(x) = -(x + 2)(x − 4).

y = -2x + 12 is the linear equation's slope intercept form.

In the form of a slope-intercept equation, the line's equation is stated as follows: y = mx + b, where m denotes the slope and b denotes the y-intercept.

Values for the slope and y-intercept describe the properties of the relationship between the two variables x and y.Slope is a measure of how quickly y changes for every unit change in x.

In the event that the x-value is 0, the y-intercept shows the y-value. An equation's slope intercept form is shown as follows:

y = mx + c

where

slope = m

y-intercept = c

Therefore,

4x + 2y = 24

2y = -4x + 24

multiply both sides by two.

2y / 2 = -4x /2 + 24 / 2

y = -2x + 12

Answer:

Yes because the distance of (7,-7) from origin is equal to the radius of the circle.

Step-by-step explanation:

The radical expression is written as 38 in its simplest form.

A mathematical expression shows the value of something by combining numbers, variables, and operators. A mathematical statement known as an equation involves setting two expressions equal to one another.

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows: Expression: (Math Operator, Number/Variable, Math Operator)

1 + 7n - 5 will therefore equal:

The sample size should be e) 2,500.

To calculate the sample size needed for the manager's confidence interval, we need to use the formula for the margin of error:

Margin of error = z * (standard deviation of the sample proportion) / sqrt(sample size)

Given the sample data, the sample proportion of time spent mowing is 200 / 400 = 0.5.

Plugging in the values, we get:

Margin of error = 1.96 * sqrt(0.5 * 0.5 / 400) = 0.02

Rearranging the formula and solving for the sample size, we get:

Sample size = (z / margin of error)^2 * (sample proportion * (1 - sample proportion))

= (1.96 / 0.02)^2 * (0.5 * 0.5)

= 2500

So, the sample size needed for a 95.44 percent confidence interval with a margin of error of 0.02 is 2,500. The answer is option (e).

The simplification of csc²x-cscx+2/CSCX-1 = 1/sin²(x) - sin(x) / (sin²(x)-1)

First, let's recall the definition of cosecant (csc): it's the reciprocal of sine, so csc(x) = 1/sin(x).

Next, we can simplify the equation by substituting the definition of cosecant into the equation:

csc²x-cscx / CSCX-1 = (1/sin(x))² - (1/sin(x)) / (1/(sin(x))-1)

Next, we can simplify the numerator and denominator using algebraic identities:

(1/sin(x))² = 1/sin²(x)

(1/sin(x)) / (1/(sin(x))-1) = sin(x) / (sin²(x)-1)

So, the equation becomes:

Answer:

3: Multiplying the first equation by −2 so the x-variables are eliminated.

Step-by-step explanation:

The elimination method is a strategy to solve a system of linear equations by eliminating one of the variables (usually the y variable) by adding or subtracting the equations. This can be done by multiplying one or both of the equations so that when added or subtracted, the y variable will cancel out.

In this case, the best option for multiplying to solve the system using the elimination method is to multiply the first equation by -2 so that the x-variables are eliminated. This is because when the first equation is multiplied by -2, it becomes -6x + 12y = 8, which has the same coefficient for x as the second equation. When the two equations are added, the x variable will cancel out, leaving us with an equation in terms of y, which can then be solved for x.

The equation after the elimination will look like this:

-6x + 12y + 6x + 11y = -2 + 8

6y = 6

y = 1

Finally, we can use this value of y to solve for x in one of the original equations:

3x - 6(1) = 4

3x = 10

x = 10/3 = 3.33

So the solution to the system is (3.33, 1).

Answer:A function f(x) is even if f(-x) = f(x). The function is odd if f(-x) = -f(x). An even function has reflection symmetry about the y-axis. An odd function has rotational symmetry about the origin.

Step-by-step explanation:

The function is even when f(-x) = f(x) and is odd when f(-x) = -f(x).This has been obtained using even-odd functions.

What are even-odd functions?

When the output value of a real-valued function, f(x), is equal to f(x), for all values of x inside the domain of f, the function is said to be an even function.

It is claimed that a real-valued function f(x) is an odd function when, for all values of x in the domain of f, the output value of f(-x) is equal to the negative of f(x).

We have an even function if we have an expression that is equivalent to f(x) and we have an odd function if we obtain an expression that is equivalent to -f(x).

If we take a function and substitute x for -x, simplify the result, and then compare it to what you started with, you can "determine algebraically" if the function is even, odd, or neither.

The function is even if you come out with exactly what you started with (i.e., if f (-x) = f (x), in which case all of the signs are the same. If you come out with exactly the opposite of what you started with (i.e., if f(-x) = -f (x), in which case all of the signs are switched), it is an odd function.

Hence, the function is even when f(-x) = f(x) and is odd when f(-x) = -f(x).

The relative frequency of responders who chose the vegetarian meal is 0.5, or 50%.

The concept used in this problem is relative frequency, which is a measure of the number of times an event occurs in a data set, expressed as a fraction of the total number of events.

The relative frequency is a useful tool for summarizing and understanding the distribution of data, and provides a way to compare the relative frequencies of different events in a data set.

To create a relative frequency distribution in Excel, you would first create a table with the four meal options (chicken, fish, steak, and vegetarian) and count the number of times each option was selected. The relative frequency is calculated as the count of each meal option divided by the total number of responses (20 in this case).

Here is the frequency distribution as :

Meal Option → Frequency → Relative Frequency

Chicken → 6 → 0.3 (6/20)

Fish → 2 → 0.1 (2/20)

Steak → 2→ 0.1 (2/20)

The total area of the ribbon is equals to 46 sq. inches with a 4 square inches of school logo in between.

The four-sided polygonal shape known as a quadrilateral has four edges and four corners. The Latin words quadri, a variation of four, and latus, meaning "side," were used to create the term.

In American and Canadian English, a quadrilateral having at least one set of parallel sides is referred to as a trapezoid. It is referred to as a trapezium in British and other varieties of English. In Euclidean geometry, a trapezoid is a convex quadrilateral by definition. The bases of the trapezoid are the parallel sides.

The total area of the ribbon = area of the top square + area of the bottom trapizium

Area of the square = 4*4 = 16 sq. inches

Area of the trapizium = (1/2)*(sum of parallel sides)*height = (1/2)*(4+8)*5 = 30 sq. inches.
