Is the square root of 2 equal to 2?

The length of a leg of an isosceles right triangle can be found using the concept of Pythagoras' theorem by the formula sqrt (hypotenuse ^ 2 / 2) = x.

Since, two sides of an isosceles triangle are equal, let us consider the two equal sides as 'x' and let the hypotenuse of the triangle be 'h'.

Being a right triangle, by Pythagoras' theorem,

h ^ 2 = x ^ 2 + x ^ 2

h ^ 2 = 2x ^ 2

Hence, we can find the length of a leg of an isosceles triangle by:

sqrt (h ^ 2 / 2) = x

To graph the equation y= −4/5x on the coordinate plane, we can plot two points that satisfy the equation and then draw a straight line through those points. For example, we could choose the points (-1, 4/5) and (2, -8/5), which both satisfy the equation. To plot these points, we first locate the point (-1, 4/5) on the coordinate plane. This point is 1 unit to the left of the y-axis, and 4/5 units above the x-axis. We can then draw a straight line through this point and the point (2, -8/5), which is 2 units to the right of the y-axis and 8/5 units below the x-axis. This line will be the graph of the equation y= −4/5x.

The fractional notation ¾ is equal to 0.75.

â…” is a fractional notation that refers to the fraction 3/4, which is equal to 0.75. To understand this fraction, the denominator (bottom number) must be multiplied by the numerator (top number). In this case, 4 multiplied by 3 is equal to 12. Then, divide the numerator by the denominator to find the fractional value. In this example, 3 divided by 4 is equal to 0.75, which is the same as 3/4.

The formula for finding a fractional value is:

Fractional Value = Numerator / Denominator

To calculate the fractional value of 3/4, the numerator is multiplied by the denominator to get 12. Then, the numerator is divided by the denominator to get the fractional value:

Fractional Value = 3 / 4

Fractional Value = 3 * 4 / 4

Fractional Value = 12 / 4

Fractional Value = 0.75

Therefore, the fractional notation ¾ is equal to 0.75.

To solve the system of equations using substitution method for three variables minimum three equations are required using following steps:

1. Get the value third variable in form of other two and substitute in other two equations.

2. Now get the value of second variable in first variable and get the value of all three variables.

Let us consider three system of equations in three variable are :

x + y + z = 0   __(1)

2x + 3y + z = 2 __(2)

3x + 2y + 2z = 1  ____(3)

Get the value of z in form of x and y from (1) and substitute in (2) and (3)

z = -(x + y)

2x + 3y -(x + y) = 2

⇒x +2y = 2   __(4)

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

⇒3x + 2y -2x -2y =1

⇒x = 1

Now substitute in (4)

1 + 2y = 2

⇒ y = 1/2

Now substitute the value of x and y in (1)

Answer: 19.625 ft^2

Step-by-step explanation: To calculate the area of a circle you have to use Area=pi*r^2, so the radius is 2.5 ft, Area = 3.14*2.5^2 = 19.625 ft^2

Answer:

Step-by-step explanation:

Done the I-ready.

Answer:

19.25 feet

Step-by-step explanation:

Let x be the width of the rectangle in feet. Then, the length of the rectangle is x + 3.5 feet. Since the area of a rectangle is equal to its length times its width, we know that the area of the rectangle is (x + 3.5) * x = 65 square feet.

We can solve for x by setting up the equation (x + 3.5) * x = 65 and then solving for x. This gives us the following:

x^2 + 3.5x - 65 = 0

To solve this quadratic equation, we can use the quadratic formula:

x = (-b +/- sqrt(b^2 - 4ac)) / 2a

In this case, a = 1, b = 3.5, and c = -65, so we have:

x = (-3.5 +/- sqrt(3.5^2 - 4(1)(-65))) / 2(1)

Solving for x, we get:

x = (-3.5 +/- sqrt(12.25 + 260)) / 2

Therefore, the width of the rectangle is x = (-3.5 +/- 19.25) / 2 = -0.75 or 15.75 feet. Since the length of the rectangle is x + 3.5 feet, this means that the length of the rectangle is (-0.75 + 3.5) feet or (15.75 + 3.5) feet, which is equal to 2.75 feet or 19.25 feet.

However, we know that the length of the rectangle must exceed its width by 3.5 feet, so the only solution that is physically possible is x = 15.75 feet and the length of the rectangle is 19.25 feet. Therefore, the length of the rectangle is 19.25 feet.

The leading coefficient is the number that appears before the variable with the highest exponent in a polynomial. It can be either a positive or a negative number.

The leading coefficient is the coefficient, or number, that appears before the variable with the highest exponent in a polynomial. This coefficient helps determine the end behavior of a graph, which means it can either be a positive or a negative number. For example, if the leading coefficient is a positive number, then the graph will have an upward trend on either side of the y-axis, or the x-axis. If the leading coefficient is a negative number, then the graph will have a downward trend on either side of the y-axis, or the x-axis. Additionally, the leading coefficient can also help determine the degree of a polynomial. For example, the leading coefficient of a polynomial with a degree of two will always be a positive number, while the leading coefficient of a polynomial with a degree of three will always be a negative number. In conclusion, the leading coefficient can be either a positive or a negative number and plays an important role in determining the end behavior of a graph and the degree of a polynomial.

Mode is the most common value in the dataset.

The Median of the following observation 65,75 and 80 is 75.

Median is one indicator of central tendency. The value that falls in the middle of the given range of integers is known as the median. In a given data sample, it divides the higher half from the lower half. A minimum of half of the observations fall below or are equal to the median, and a minimum of half of the observations fall above or are equal to the median.

If a data collection has an odd number of observations, the median can be determined as follows:

Step 1: sort the information into ascending or descending order.

3x - 5y=-9 has a [tex]\frac{-3}{5}[/tex] slope.

A line's steepness can be determined by looking at its slope. To find the slope of a line, you need to have the equation of the line in the form y = mx + b, where m is the slope and b is the y-intercept (the point at which the line crosses the y-axis).

To put the equation 3x - 5y = -9 in this form, you can start by isolating the y term on one side of the equation:

3x - 5y = -9

-5y = -3x - 9

y = (-3/5)x - (9/5)

The intercept theorem, also referred to as Thales' theorem, the basic proportionality theorem, or the side splitter theorem, is a crucial concept in basic geometry that discusses the ratios of different line segments that are produced when two intersecting lines are intercepted by a pair of parallels.

It is equivalent to the ratios in similar triangles theorem. It is typically credited to the Greek mathematician Thales. Despite the fact that its first known demonstration may be found in Euclid's Elements, it was known to the ancient Babylonians and Egyptians.
