Anna must sell at least approximately 1.845 books to make a profit.

What is the linear equation?

A linear equation is an algebraic equation of the form y=mx+b. where m is the slope and b is the y-intercept.

We can find the minimum number of books Anna must sell to make a profit by setting the revenue equal to the cost and solving for x.

That is, we want to find the value of x where R = C:

6.56x = 10.063 + 1.09x

5.47x = 10.063

x = 10.063 / 5.47

x = approximately 1.845 books

Hence, Anna must sell at least approximately 1.845 books to make a profit.

For square, Functions will be A=s², s=√A, s=√(d²/2), d=√2s², p=4s, s=p/4, A=(p/4)², d=√2A.

What exactly is a function?

A function is defined as a relationship between a group of inputs that each have one output. A function is a connection between inputs in which each input is associated to exactly one output. Every function has a domain and a co-domain, as well as a range. In general, a function is denoted as f(x), where x represents the input. A function's generic representation is y = f. (x).

In mathematics, there are several types of functions. Some examples include:

When there is a mapping for a range for each domain between two sets, this is referred to be an injective function or a one to one function.

Surjective functions, also known as Onto functions, are used when more than one element is transferred from domain to range.

Polynomial function: A function made up of polynomials.

Inverse Functions: A function that may be used to inverse another function.

Now,

As given square with side of length s, diagonal of length d, perimeter P, and area A.

and Area=side²

Perimeter=4*side

diameter²=side²+side²

then A=s² and s=√A,  s=√(d²/2) and d=√2s²,  p=4s and s=p/4, A=(p/4)², d=√2A.

Hence,

            For square, Functions will be A=s², s=√A, s=√(d²/2), d=√2s², p=4s, s=p/4, A=(p/4)², d=√2A.

... ...

Proof:

Suppose m is an odd integer. We can write m as 2n + 1 for some integer n. Then,

m + 1 = (2n + 1) + 1 = 2n + 2

Since 2n + 2 is clearly an even integer, it follows that m + 1 is an even integer if m is an odd integer.

Proof:

Suppose x is an even integer and y is an odd integer. We can write x as 2n and y as 2m + 1 for some integers n and m. Then,

x + y = 2n + (2m + 1) = 2(n + m) + 1

Since n + m is clearly an integer, it follows that x + y is an odd integer if x is an even integer and y is an odd integer.

Proof:

Suppose m is an even integer. We can write m as 2n for some integer n. Then,

3m^2 + 2m + 3 = 3(2n)^2 + 2(2n) + 3 = 12n^2 + 4n + 3

Since 12n^2 + 4n + 3 is clearly an odd integer, it follows that 3m^2 + 2m + 3 is an odd integer if m is an even integer.

The three points that are in the solution set are (-2,6), (-5,5), and (3,-9). Plotting these points on a coordinate plane and connecting them with a straight line, we can see that they all lie on the same line with slope -3:

[Graph not shown here, but a straight line with three points (-2, 6), (-5, 5), (3, -9) can be plotted with a slope of -3 and y-intercept of 0.]

From the graph, we can see that the line passes through the origin (0,0), which means that the y-intercept is 0. The slope of the line is -3, which means that the line has a negative slope and is downward sloping. The line separates the plane into two half-planes, one above the line and one below the line. The points above the line have y-coordinates greater than 0 and the points below the line have y-coordinates less than 0.

we have AB as a, AD as b and the angle between them is theta.

So using the cosine rule, we have

  BD = √a² + b² - 2abcosθ

So now consider the triangle ABC

Here AB is a, BC is b and the angle is 180-theta

So using cosine rule, we get AC as

   AC = √a² + b² - 2abcosθ( 180 - θ )

    AC = √a² + b² - 2ab(-cosθ )

    AC = √a² + b² - 2abcosθ

Now we have the two diagonals AC and BD. So multiplying, we get

 AC × BD = √a² + b² + 2abcosθ × √a² + b² - 2abcosθ

Simplifying, we get

AC × BD = √(a² + b² + 2abcosθ) × (√a² + b² - 2abcosθ)

A quadratic function with x-intercepts as (-2,0) and (1,0) and y-intercept as (0,-2) is y = x² + x - 2.

What is a quadratic function?

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree.

It is given that the x intercepts of the quadratic function are (-2,0) and (1,0).

The y intercept of the quadratic function is (0,-2).

Let the equation of the given quadratic be y = ax² + bx + c.

As the given quadratic has x intercepts as (-2,0) and (1,0) and y intercept as (0,-2).

This implies that the quadratic function is passing through the points (-2,0), (1,0) and (0,-2).

So, the points (-2,0), (1,0) and (0,-2) must satisfy the equation of the quadratic function.

As the point (-2,0) satisfy the equation of the quadratic function -

y = ax² + bx + c

0 = a(-2)² + b(-2) + c

0 = 4a - 2b + c ..... (1)

As the point (1,0) satisfy the equation of the quadratic function -

y = ax² + bx + c

0 = a(1)² + b(1) + c

0 = a + b + c ..... (2)

As the point (0,-2) satisfy the equation of the quadratic function -

y = ax² + bx + c

-2 = a(0)² + b(0) + c

-2 = c ..... (3)

Substitute the value of c in equation (1) -

0 = 4a - 2b - 2

2 = 4a - 2b ...... (4)

Substitute the value of c in equation (2) -

0 = a + b - 2

2 = a + b ...... (5)

Multiply equation (5) by 2 -

4 = 2a + 2b ...... (6)

Add equation (4) and (6) -

2 + 4 = 4a - 2b + 2a + 2b

6 = 6a

a = 1

Substitute the value of a in equation (5) -

2 = 1 + b

b = 2 - 1

b = 1

The values are a = 1, b = 1 and c = -2.

Now substitute the value of a, b and c in the quadratic function.

y = ax² + bx + c

y = (1)x² + (1)x + (-2)

y = x² + x - 2

Therefore, the quadratic function is y = x² + x - 2.

The expression that is equivalent to (1 + cos(x))2Tangent (StartFraction x Over 2 EndFraction) ) is option D. (1 + cos(x))(sin (x))

The expression (1 + cos(x))2Tangent (StartFraction x Over 2 EndFraction) is equivalent to (1 + cos(x))(sin (x)) because of the double angle identity for tangent.

The double angle identity states that tangent of 2 times an angle is equal to 2 times the tangent of that angle divided by 1 minus the square of the tangent of that angle. In other words,

tan(2θ) = 2tan(θ)/(1 - tan2(θ))

In this expression, we have tangent of x/2, so substituting θ = x/2 gives us:

tan(x) = 2tan(x/2)/(1 - tan2(x/2))

Since cos(x) = 1 - 2sin2(x/2), we can simplify the expression to:

(1 + cos(x))2tan(x/2) = (1 + 1 - 2sin2(x/2))2tan(x/2) = (2 - 2sin2(x/2))(2sin(x/2)/(1 - sin2(x/2)))
