The quotient of the given division is (x + 9).

What is synthetic division?

Synthetic division is a technique for performing manual Euclidean division of polynomials in algebra that requires less writing and calculation than long division. Although it is typically taught for division by monic linear polynomials, the technique can be applied to division by any polynomial.

Given:  x^2 - 81 / (x - 9)

We have to find the quotient for the given division.

We can find the quotient using synthetic division.

                       x + 9

                 [tex]\sqrt[x-9]{x^2-81}[/tex]

                 -    x^2 - 9x

              _______________

If Two signs that scores are significantly different then (a) the error bars of group will not overlap

Error bars are graphical representations of data variability that are used to indicate the error or uncertainty in a reported measurement on graphs.

The estimated error in a measurement is indicated by error bars. In other words, an error bar represents the degree of uncertainty in a value.

When the standard deviation error bars overlap significantly, it is an indication that the difference is not statistically significant. To reach a conclusion, you must conduct a statistical test.

When the standard deviation error bars overlap even less, it indicates that the difference is unlikely to be statistically significant.

For significantly different group , we also have p-value greater than 0.05

So, Option (b) is incorrect.

The formula is Y=kx.

the financial gain experienced when the income from a commercial activity is greater than the costs, taxes, and other costs associated with maintaining the activity in question.

When laying sod, the equation to determine sakeem's profit is Y= KX, where y represents profit, x is the number of square feet of sod, and k is a constant.

His supplier bills him $0.43 per square foot for sod when he builds a lawn.

For laying the sod, Sakeem's costs his clients $2.00 per square foot.

The amount of sod used to create a lawn directly affects how much money Sakeem's makes.

Answer: If a1 = 16 and a2 = -8, then we can write a recursive formula for the nth term of the sequence as follows:

an = a(n-1)/2

This formula states that the nth term of the sequence is equal to the previous term (n-1) divided by 2. For example, if n = 3, then a3 = a(3-1)/2 = a2/-8/2 = 4.

We can also write this formula in terms of the initial values of the sequence as follows:

a(n) = (-1)^(n-1) * 8

This formula states that the nth term of the sequence is equal to (-1) raised to the power of (n-1), multiplied by 8. This formula will always give the correct value for the nth term of the sequence, regardless of the initial values of the sequence.

The Range of the length of a rectangle having fixed width and area increasing linearly is  = {y ∈ R : c ≠ 0 or y ≠ 0}, and Domain = All real numbers,

An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°). A rectangle has equal and parallel, opposite sides. Since a rectangle is a two-dimensional form, it has two dimensions: length and width. The rectangle's longer side is its length, while its shorter side is its breadth.

Given:

The width of the rectangle is fixed, and the length is changing.

The line is formed when connected through the graph.

The area of the rectangle = [tex]length\times width[/tex]

So when the width is fixed, the area would increase linearly and directly proportional to length.

Calculate the range of function y = cx,

y = area as shown in the graph, x is the length, and width is constant c.

Range = {y ∈ R : c ≠ 0 or y ≠ 0}

Calculate the domain,

It can be any real number, as the area can't be negative.

Domain = All real numbers.

Therefore, Range = {y ∈ R : c ≠ 0 or y ≠ 0}, and Domain = All real numbers.

When we say, "a system of linear equations works" it means that the linear equations share one or more ordered pairs (x,y) when graphed.

In many practical applications in daily life, linear equations are a crucial tool in science. They enable scientists to, among other things, make predictions, compute rates, and characterize relationships between two variables in the physical world. In order to see trends, linear equations are often graphed.

Slope intercept form, direct variation, point slope form and standard form are four types of linear functions.

When we have a system of linear equations and when we solve them simultaneously we get one or more ordered pair depending upon the variable in system.

The slope of the line y = 14x – 1 is 14.

To find the slope of a line, we need to know two points on the line. We can choose any two points, as long as they are not the same. For example, we can choose the points (0, -1) and (1, 13):

y = 14x – 1

y = 14(0) – 1 = -1 when x = 0

y = 14(1) – 1 = 13 when x = 1

The slope of the line is the change in y divided by the change in x between these two points. In this case, the change in y is 13 – (-1) = 14, and the change in x is 1 – 0 = 1. Therefore, the slope of the line is 14/1 = 14.

We can also write the slope as a simplified fraction. In this case, 14 is already a simplified fraction, so we don't need to simplify further. Therefore, the slope of the line y = 14x – 1 is 14.

Answer:

A.) [tex]\frac{1}{5^6}[/tex]

Step-by-step explanation:

To simplify [tex](5^2)^3[/tex], use the exponent rule that states [tex](a^m)^n=a^{mn}[/tex]

So,

[tex](5^2)^3=5^{2*3}=5^6[/tex]

Use the same exponent rule to begin simplifying [tex](5^4)^{-3}[/tex]:

[tex](5^4)^{-3}=5^{4*(-3)}=5^{-12}[/tex]

To further simplify [tex]5^{-12}[/tex], use the exponent rule that states [tex]a^{-m}=\frac{1}{a^m}[/tex]

So,

[tex]5^{-12}=\frac{1}{5^{12}}[/tex]

Then multiply the two new expressions as indicated in the original problem:

[tex](5^6)(\frac{1}{5^{12}})=\frac{5^6}{5^12}=\frac{1}{5^6}[/tex]

Alternatively, you could use the exponent rule that states [tex]a^m*a^n=a^{m+n}[/tex]

where

[tex]a^m=5^6\\a^n=5^{-12}[/tex]

So,

Square is a polygon which has 4 sides. All four sides of square are equal length and perpendicular to each other that means the angle between two adjacent side is 90°.

Given that ABCD is a square surface. And diagonal of square creates two isosceles triangles.

So the ∠ABC = ∠BCD = ∠CDA = DAB = 90°

Here, BD and AC are two diagonals of a square ABCD and E is the intersection point of diagonals.

Diagonals cut each other perpendicular.

So, ∠AED = 90°  and ∠EAD = ∠EDA = 45°

Now to find ∠BAC;

we have ∠ABC = 90° so from the property of isosceles triangle

∠BAC = ∠BCA = 45°

In isosceles triangle BCD,

∠BCD = 90° and ∠DBC = ∠BDC = 45°
