The pair of vertical angles are

There are four angles made by the intersection of two lines. Those are ∠1, ∠2, ∠3 and ∠4

Vertical angles are the each of opposite angles formed when two lines meet each other at a point. So whenever two lines intersect each other four angles are formed and each set of opposite angles are called vertical angles

Here, two lines intersect each other and ∠1, ∠2, ∠3 and ∠4 are formed.

∠1,∠3 and ∠2,∠4 are the opposite angles

So the vertical angles are ∠1,∠3 and ∠2,∠4

Hence, the pair of vertical angles are

The division of (4+5i) / (2-4i) is performed by multiplying the numerator and denominator by 2+4i and the result of the given expression is (-3/5) + (13/10) i

The given expression is

(4+5i) / (2-4i)

Here we have to divide the given complex number

First multiply both numerator and denominator by 2+4i

(4+5i) / (2-4i) × (2+4i) / (2+4i)

= [tex]\frac{(4+5i)(2+4i)}{(2-4i)(2+4i)}[/tex]

Multiply the terms in the numerator and denominator.

= [tex]\frac{8+16i+10i-20}{2^2+4^2}[/tex]

= (-12+26i) / 20

= (-12/20) + (26/20)i

Divide both numerator and denominator by common terms

= (-3/5) + (13/10)i

Hence, the division of (4+5i) / (2-4i) is performed by multiplying the numerator and denominator by 2+4i and the result of the given expression is (-3/5) + (13/10)i

Answer: Look at step by step

Step-by-step explanation:

(ax + b)(ax + b) = [tex]a^{2}[/tex] [tex]x^{2}[/tex]+ 2abx + [tex]b^{2}[/tex]

Substitute g into x

[tex]a^{2}[/tex] = 7

a = [tex]\sqrt{7}[/tex]

2ab = -3

b = -3 / (2 x [tex]\sqrt{7}[/tex])

[tex]b^{2}[/tex] = 9 / (4 x 7) = 9/28

So the term to be added to make a perfect square is 9/28

When factorized would get ([tex]\sqrt{7}[/tex]x - 3/2[tex]\sqrt{7}[/tex])([tex]\sqrt{7}[/tex]x - 3/2[tex]\sqrt{7}[/tex])

The range of the function, f(x), that gives the total cost of the cleats of given that each cleat costs $15 and the number of cleats, x, is 5 ≤ x ≤ 9 is RANGE: [75, 135]

The range of a function is the set containing the output values that are obtainable with the function.

The given parameters are;

The number of players, n, in the sports team is; 5 ≤ n ≤ 9

The given cost of one cleat = $14

The function that represents the total cost of the cleats for the team is f(x) = 15•x

Given that each team member is given one cleat, we have;

Using the vertical angle image we get the following answers:

Given the equations are:

42 = 4x-4 and 24 = x+50.

According to vertical angles theorem, when two lines intersect the opposite angles are equal and adjacent angles are supplementary.

we know that,

∠2 = 4x-4 and ∠4 = x+50

a)To Find the value of x:

4x - 4 = x + 50

4x - x = 50 + 4

3x = 54

x = 54/3

x = 18

b) To Find the measure of ∠2:

∠2 = 4×18 - 4 = 72 - 4

= 68

c)  Angles 2 and 3 are supplementary so their sum is 180°.

∠2 + ∠3 = 180

68 + ∠3 = 180

∠3 = 180 - 68

∠3 = 112°

The Inequality notation of the given equation 10+3x>-16 is x > -2

What is Inequality notation?

A mathematical statement known as an inequality expresses the relationship between two quantities while indicating that they are not completely equal. The four symbols used to represent inequality are. ≥, >,<, and ≤.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare the two values in inequality. Less than (or less than and equal to), greater than (and greater than or equal to), and also not equal to signs are used in place of the equal sign.

Consider the above equation.

-10 +3x > -16

Add 10 on both sides.

= -10+3x+10> -16+10

= 3x> -6

Divide by 3 to equation into both sides.

= [tex]\frac{3x}{3} > \frac{-6}{3}[/tex]

The rate of change of the function shown in the graph is $0.5 per minute.

What is rate of change?

The rate of change (ROC) measures how quickly a variable alters over a predetermined amount of time. When discussing momentum, the term "rate of change" is frequently used. It is typically defined as the ratio of a change in one variable to a matching change in another; visually, the rate of change is represented by the slope of a line. The Greek letter delta (Δ) is usually come in use to represent the ROC.

As shown in the graph,

The x-axis represents the minute and y-axis represents the cost.

and the cost is function of time.

For each 10 minute the cost increased $5

So, the cost is changing at a rate of $5 per 10 minute

$5 = 10 minutes

diving both side with 10

$0.5 = 1 minute

Therefore, the rate of change of the function shown in the graph is $0.5 per minute.

(x-2) is not a factor of f([tex]x[/tex]) = [tex]3x^{4}-3x^{3}-9x^{2} +5x-2[/tex].

Remainder Theorem is an approach of Euclidean division of polynomials. According to this theorem, if we divide a polynomial P(x) by a factor ( x – a) that isn't essentially an element of the polynomial, you will find a smaller polynomial along with a remainder.

The Remainder Theorem: If (x-a) is a factor of the f(x) then f(a) = 0

We are given a line segment as MN with its' endpoint coordinates as;

M(4,14) and N(13,8)

Now, point O divides MN such that MO:NO is 2:1.

Now, the formula for the coordinate of the point that divides a line segment in the ratio a:b is;

(x, y) = (ax₂ + bx₁)/(a + b), (ay₂ + by₁)/(a + b)

Since point O is the point that divides the line segment in the ratio 2:1, we have;

O(x, y) = (2*13 + 1*4)/(2 + 1), (2*8 + 1*14)/(2 + 1)

The statements that are true about the quadratic function and its graph include the following:

In Mathematics, the graph of any quadratic function or equation always forms a parabola because it is a u-shaped curve. For the given quadratic function, the graph is a upward parabola because the coefficient of x² is positive i.e when the value of "a" is greater than zero.

Next, we would determine the statements about the quadratic function and its graph that are true:

At point (-10, 82), we have:

f(x) = 1/5 x² – 5x + 12

f(x) = x²/5 – 5x + 12

f(-10) = -10²/5 – 5(-10) + 12

f(-10) = 82

At point (20, -8), we have:

f(x) = 1/5 x² – 5x + 12

f(x) = x²/5 – 5x + 12

f(20) = 20²/5 – 5(20) + 12

f(20) = -8

What is inequality?

In mathematics, the term 'inequality' is defined as a statement or equation with an ordered relationship like greater than, greater than or equal to, less than, less than or equal to- between two numbers or algebraic equations.

Now the given inequality is,

-5 < 9- 6x

Adding 5 both the side we get,

5 - 5 < 9 - 6x + 5

⇒ 0 < 14 - 6x

⇒ 14 - 6x > 0

Dividing both the side by 6 we get,

⇒ 14 < 6x

⇒ x > 14/6 = 7/3

or, x ≤ 7/3

If wasps had eaten 20 apples then, 50 rotten apples were there and the rest of the apples were quality apples in the ratio of 4: 10: 20 respectively.

This is a problem from simple mathematical equations. We can solve this problem by following a few steps.

Let's consider x as the highest common factor of apples eaten by wasps, rotten and quality apples.

So, the number of apples eaten by wasps is, 4 × x = 4x

The number of rotten apples is, 10 × x = 10x

The number of quality apples is, 20 × x = 20x

As, we all know HCF of the numbers × ratio of numbers = The numbers

So, 4x = 20 as per the question.

Therefore, x = 5.

Now, we can write that the HCF is 5.
