How do you find the inverse of x and y intercepts?
When the original graph is mirrored around the line y = x, the inverse function's graph may be determined, the domain of the inverse, f-1(x), corresponds to the range of the original function (x), the x intercept of f-1(x) is the y intercept of f, and the range of the inverse f-1(x) is the domain of f(x) (x).
What is a intercept theorem?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.
Similarity and the intercept theorem go hand in hand. It is equivalent to the idea of similar triangles in that it may be used to demonstrate both the qualities of similar triangles and the intercept theorem.
Hence, When the original graph is mirrored around the line y = x, the inverse function's graph may be determined, the domain of the inverse, f-1(x), corresponds to the range of the original function (x), the x intercept of f-1(x) is the y intercept of f, and the range of the inverse f-1(x) is the domain of f(x) (x).

What is the standard deviation of 25?
Variance's square root is always the standard deviation. √25 thus equals 5.
Describe the term standard deviation?Both the standard deviation and the variance are indicators of how far data deviates from the mean. Because the results are all in data form or units, S.D. provides accurate results. Variance produces squared data findings, making it challenging to compare to actual data. Therefore, it makes sense to compare findings using S.D. rather than variance.Saying that the median is 7, the mode is 2, and the variance is squared does not make much sense.
However, it makes sense to state that the data's median, mode, and standard deviation are 7, 2, and 4, respectively.
Variance produces squared findings that make it impossible to compare to actual data without. You can only understand differences from getting S.D.Thus,
√25 = 5.

Is the leading coefficient a positive or a negative number?
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.

What is y =- 4 on a graph?
Answer:
I think it's a vertical line.
Graph the equation on the coordinate plane. y= −4/5x Select two points on the line to graph the line.
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.

A cannonball is shot with a speed of 90 m/s. Assuming its upward speed at the highest point of its curve is 0 m/s and the flat speed at the highest point of its bend is 45 m/s.
We know that in projectile motion, the horizontal velocity does not change.
Let 'x' be the angle it shot. Then the cosine of the angle x is the ratio of horizontal velocity to the resultant velocity when it is shot. Then we have
cos x = 45 / 90
cos x = 1/2
cos x = cos 60°
x = 60°

What is â…” equal to?
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.

The length of a rectangle exceeds its width by 3 and a half feet. The area of the
rectangle is 65 square feet. Find its length.
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.

What is the slope of 3x 5y =- 9?
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)
