Answer:

12097.8001

Step-by-step explanation:

Heron's formula is a formula used to calculate the area of a triangle when the lengths of its three sides are known.

It is named after Hero of Alexandria, a Greek mathematician and engineer who first derived this formula.

The formula states that the area of a triangle is equal to the square root of the product of the semi-perimeter (half the sum of the three sides) and the differences of the semi-perimeter and each side.

Mathematically, Heron's formula can be written as:

A = √(s(s-a)(s-b)(s-c)),

where A is the area of the triangle, s is the semi-perimeter and a, b, c are the length of the three sides of the triangle.

For example, if the lengths of the three sides of a triangle are 5 cm, 6 cm and 7 cm, then the semi-perimeter (s) is (5 + 6 + 7)/2 = 9 cm.

Using Heron's formula, the area of the triangle is:

A = √(9(9-5)(9-6)(9-7)) = √(9*4*3*2) = √432 = 6.48 cm2

By graphing the system of equations, we can see that the solution of the system is (-5, -3).

Here we want to solve the following system of equations:

y = (2/5)*x - 1

2x - 3y + 1 = 0

To solve a system of equations graphically, we just need to graph both equations on the same coordinate axis, and then find the point where the two lines do intersect.

The graph of the system of equations can be seen on the image below.

Below you can see the graph of the system of equations, and you can see that the graphs intercept at the point (-5, -3)

To check if this is a solution, just replace these values in both equations and see if you get the same thing.

For the first one:

-3 = (2/5)*-5 - 1

-3 = -2 - 1

-3 = -3

And for the other line

2*-5 - 3*-3 + 1 = 0

The length available will be (300-W) feet, where W represents the breadth (width) of the rectangle.

Let L, A, and W represent the length, area, and width of the rectangular field respectively.

A quadrilateral with parallel sides equal to one another and four equal vertices is known as a rectangle. It is also known as an equiangular quadrilateral for this reason.

The area a two-dimensional form occupies in a plane is known as its area. It has a square unit of measurement. As a result, the rectangle's area is the space enclosed by its exterior lines. It is the same as the length times the width calculation.

Rectangles can also be referred to as parallelograms since their opposite sides are equal and parallel.

Based on the data given we have,

2L + 2W = 60

=>2L=60-2W

=>L=(60-2W)/2

So the value of a, b, c are 2, -5, √2 respectively

Therefore, the discriminant is (-5)² - 4(2)(√2) = 25 - 8√2

So, The discriminant for √ 2x² − 5x+ √ 2 = 0 is -8√2

Answer:

The discriminant of a quadratic equation ax² + bx + c = 0 is given by the formula:

b² - 4ac

Given the equation √ 2x² − 5x + √ 2 = 0, we can find the discriminant by substituting the values of a, b, and c into the formula:

b² - 4ac = (-5)² - 4(√2)(√2) = 25 - 8 = 17

What is the graph of a function?

The graph of a function is a visual representation of the relationship between the input values (x-coordinates) and the output values (y-coordinates) of the function. In other words, it is a visual representation of the function's rule.

The graph of a function can take many different forms, depending on the function's rule. Linear functions, for example, will produce a straight line on the graph.

-4y > -x + 12 is a linear inequality. To solve this inequality, we can start by isolating y:

y < x/4 - 3

This inequality is in slope-intercept form (y = mx + b), where the slope is m = -1/4 and the y-intercept is b = -3.

To graph the solution, you can pick a few x-values and substitute them into the inequality to find the corresponding y-values.

You can use x = -8, x = -4, x = 0, x = 4, x = 8 for example and find the y-values for each x, y < -8/4 -3 = -2, y < -4/4 -3 = -1, y < 0/4 -3 = -3, y < 4/4 -3 = -1 and y < 8/4 -3 = -1/2.

Then plot those points on a coordinate plane and draw the line that goes through them, and shade the half-plane that is above the line

When a figure is dilated by a scale factor of less than 1, it becomes smaller as the coordinates of each point on the figure will be multiplied by a value less than 1. This results in a reduction of the size of the figure while preserving its shape.

For example, if a figure is dilated by a scale factor of 0.5, the coordinates of each point on the figure will be multiplied by 0.5. This means that each point on the figure will be moved half as far from the origin as it was before the dilation.

The result of this is that the dilated figure will be smaller than the original figure and will have a scale factor of less than 1.

It's important to note that if the scale factor is less than 1, the dilation will reduce the size of the figure and if the scale factor is greater than 1, the dilation will increase the size of the figure.

An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two values are not equal, most commonly use the not equal symbol (). Different inequalities are used to contrast values, no matter how small or large. Many simple inequalities can be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality: Negative values on both sides are divided or added. Trade off the left and right.
