g(x)=-x^2 is the reflection of your function f(x) over the x-axis.

What is function?

The function f(x)=x2 is a parabola facing upward with its vertex at (0,0), and including the points (1,1), (2,4), (-1,1), and (-2,4).

A function that is a reflection across the x-axis compared to f(x) would be the mirror image of f(x). It would have the opposite y-values for each x-value. It would also have its vertex at the same place as f(x).

Therefore, it would be a parabola pointing downward, with the points (1, -1), (2,-4), (-1,-1), and (-2,-4).

To get the opposite values for y, you simply need to place a negative in front of the x2. So the function would be g(x) = - x2.

Mean from a frequency table is when we find the mean average from a data set which has been organised into a frequency table.

To calculate the mean we find the total of the values and divide the total by the number of values. The number of values is the total frequency.  This can be abbreviated to nn.

[tex]Mean = \frac{total}{number of values} =\frac{total}{n}[/tex]

We can use an extra column to help.

Mean is a measure of central tendency, it is a value that can be used to represent a set of data.  

E.g. The frequency table shows the number of people living in 1616 flats.

There are 55 flats with 11 person living there, so we work out 1\times5=51×5=5

There are 66 flats with 22 people living there, so we work out 2\times6=122×6=12

There are 33 flats with 33 people living there, so we work out 3\times3=93×3=9

There are 22 flats with 44 people living there, so we work out 2\times4=82×4=8

The number of values (n)(n) is the total frequency, here n=16n=16

mean = total/n

         =34/16

         = 2.125

Yes, you can use the Side-Side-Angle (SSA) Congruence Theorem to prove that two triangles are congruent.

The SSA Congruence Theorem states that if two sides of one triangle have the same length as two sides of another triangle, and the included angle in the first triangle is congruent to the included angle in the second triangle, then the two triangles are congruent.

Here is an example of how you can use the SSA Congruence Theorem to prove that two triangles are congruent:

Let's say you have two triangles, triangle ABC and triangle DEF. You are given that the length of side AB is equal to the length of side DE, the length of side AC is equal to the length of side DF, and angle A is congruent to angle D.

To prove that triangle ABC is congruent to triangle DEF, you would need to show that all of the corresponding parts of the triangles are congruent. Since the lengths of two sides (AB and DE) and the included angle (angle A and angle D) are congruent, you can use the SSA Congruence Theorem to conclude that triangle ABC is congruent to triangle DEF.

It's worth noting that the SSA Congruence Theorem is not always sufficient to prove that two triangles are congruent. If the conditions of the theorem are not met, you may need to use other methods, such as the ASA Congruence Theorem or the HL Congruence Theorem, to prove congruence.

Real roots;-

We are aware that anytime we resolve a linear or quadratic equation, we obtain the equation's value variable, or in other words, we identify the equation's solution. We refer to this "solution" as the real roots. For instance, when we solve the equation x27x+12=0, the real roots come out to be 3 and 4.

How do you tell which roots are distinct and real?

The discriminant is the expression b² - 4ac for the quadratic equation ax² + bx + c = 0. The discriminant's value reveals how many roots f(x) has: - The quadratic function has two unique real roots if b² - 4ac > 0, otherwise it does not.

In grade 11 math, the slope is a concept that is typically introduced in the study of linear equations and graphing.

The slope of a line serves as a gauge for its steepness. It is defined as the change in y (the vertical distance) divided by the change in x (the horizontal distance) between two points on the line.

A line's slope might be zero, positive, negative, or undefinable. A line with a positive slope rises as it goes from left to right, while a line with a negative slope falls as it goes from left to right. A line with a slope of zero is horizontal, while a line with an undefined slope is vertical.

The slope is often represented by the letter m in the equation of a line, which is written in the form y = mx + b. The slope of the line is the coefficient of the x term (the m in the equation).

For example, the slope of the line represented by the equation y = 3x + 4 is 3, while the slope of the line represented by the equation y = -2x + 1 is -2.

A factor is a number that divides another number, leaving no remainder. In other words, if multiplying two whole numbers gives us a product, then the numbers we are multiplying are factors of the product because they are divisible by the product.

There are two methods of finding factors: multiplication and division. In addition, rules of divisibility may also be used.

Let f (x) = x ³ - 3x²  + ax -10 be the given polynomial.

By factor theorem,  ( x - 5 ) is the factor of f (x) , if f ( 5 ) = 0

Therefore,

f ( 5 ) = 3 ( 5 )²  + a ( 5 ) - 10 = 0

Without using a calculator, the square root of an integer is

1. Use multiplication to calculate the ideal square root.

2. Use division to calculate the ideal square root.

3. Use nearest perfect square number to find the square root of non-perfect squared numbers.

Given that,

We need to figure out how to calculate a number's square root without a calculator.

We know that,

There are some ways to find

First

Use multiplication to calculate the ideal square root.

A number that, when multiplied by itself, equals the first number is the number's square root.

3 is therefore the square root of 9.

Because 3 multiply by 3 is 9

That is 3×3=9

√9=3

Second

To calculate the square root, we use division.

A whole number can also be divided by a number until you get an answer that is the same as the number you used to divide the whole number in order to determine its square root.

For instance: Four is the square root of sixteen.

Because 16 divided by 4 is 4

That is 16÷4=4

√16=4

Third

We must compare the number with a nearly perfect squared number in order to determine the square root of non-perfect squared numbers.

For example: the square root of 63 is not a perfect square.

So,

The closest perfect square integer right now is 64, and its square root value is 8.
