It represents that it is false

Step-by-step explanation:

taking a peek at the picture, we can see that the U-turn or vertex occurs at the point (2 , -9), and we can also see that the graph passes through the point say (5 , 0).

\(\stackrel{vertex}{(2~~,~-9)}\qquad y=a(x-2)^2-9\qquad \qquad \textit{we know that} \begin{cases} x=5\\ y=0 \end{cases} \\\\\\ 0=a(5-2)^2-9\implies 9=9a\implies \cfrac{9}{9}=a\implies 1=a~\hfill \\\\\\ y=1(x-2)^2-9\implies \boxed{y=(x-2)^2-9}\)

The value of y is 18

Similar triangles have the same corresponding angle measures and proportional side lengths. The angles of the two triangle must be equal and it not necessary they have equal sides.

Therefore the corresponding angles of similar triangles are congruent and the ratio of corresponding sides of similar triangles are equal.

Therefore;

14/21 = 12/y

14y = 21 × 12

14y = 252

divide both sides by 14

y = 252/14

y = 18

Therefore the value of y is 18.

The solution set for the inequality |x-2|>3 is x < -1 or x > 5, represented by the union of the open intervals (-∞, -1) and (5, ∞) on the number line.

To graph the inequality |x-2| > 3 on a number line, we can start by finding the values of x that satisfy the inequality:

|x-2| > 3

x-2 > 3 or x-2 < -3

x > 5 or x < -1

This means that any value of x that is greater than 5 or less than -1 will satisfy the inequality.

On a number line, we can mark -1 and 5 with open circles to indicate that they are not included in the solution set, and shade the regions to the left of -1 and to the right of 5 to show that any value in those regions satisfies the inequality.

The graph should look like this:

         <=========(================>)=========

         -1       2               5

The open circles at -1 and 5 indicate that those values are not included in the solution set, while the shaded regions to the left of -1 and to the right of 5 indicate that any value in those regions satisfies the inequality.

Answer:

The magnitude of the vector is 9.165 and it's direction is 40.6°

Step-by-step explanation:

A vector quantity is a quantity that has both size (magnitude) and direction. Examples of vector quantities are force, velocity and impulse.

Magnitude of vector v is given by

|v| = √6²+7²

= √36+49

= √84

= 9.165

Direction of vector v is obtained by:

\( \tan( \theta) = \frac{x}{y} \)

\(\theta = {tan}^{ - 1} ( \frac{6}{7}) \)

\(\theta = {40.6°}\)

Using multiplication as an arithmetic operator, the number of tickets sold is 7875

Multiplication is an arithmetic operation that involves multiplying two or more numbers together. It can be written in a variety of ways, such as using a multiplication symbol, an "x" sign, or by writing out the equation. The result of multiplication is called the product.

In this problem, we can use a simple arithmetic operation to find the number of tickets sold, but we can also work it out in a step by step process.

1 times = 175 seats (tickets)

45 times = x tickets

Cross multiply both sides;

x = 45 * 175

x = 7875

The number tickets sold is 7875 tickets.

The functions that have roots at x = -1 and x = 4 are

j(x) = (-1-x)(2x-8)  and g(x) = (x+1)(x-4)

The functions that have roots at x = -4 and x = -1 are

h(x) = (-3-3x)(3x+12) and k(x) = (x+1)(x+4)

The functions that have roots at neither are

f(x) = (x-1)(x-4) and (3-3x)(3x-12)

From the question, we are to determine the quadratic functions that have the given roots

First, we will determine the roots of the given functions

Since the roots of a quadratic function will make the factors equal to 0,

Then,

(x+1)(x+4) = 0

x + 1 = 0 OR x + 4 = 0

x = -1 OR x = -4

(3-3x)(3x-12) = 0

Then,

3 - 3x = 0 OR 3x -12 = 0

3x = 3 OR 3x = 12

x = 3/3 OR x = 3/12

x = 1 OR x = 4

(x+1)(x-4) = 0

Then,

x+1 = 0 OR x-4 = 0

x = -1 OR x = 4

(x-1)(x-4) = 0

Then,

x -1 = 0 OR x -4 = 0

x = 1 OR x = 4

(-3-3x)(3x+12) = 0

Then,

-3 -3x = 0 OR 3x + 12 = 0

3x = -3 OR 3x = -12

x = -3/3 OR x = -12/3

x = -1 OR x = -4

(-1-x)(2x-8) = 0

Then,

-1 -x = 0 OR 2x - 8 = 0

x = -1 OR 2x = 8

x = -1 OR x = 8/2

x = -1 OR x =4

Hence,

The functions that have roots at x = -1 and x = 4 are

j(x) = (-1-x)(2x-8)  and g(x) = (x+1)(x-4)

The functions that have roots at x = -4 and x = -1 are

h(x) = (-3-3x)(3x+12) and k(x) = (x+1)(x+4)

The functions that have roots at neither are

f(x) = (x-1)(x-4) and (3-3x)(3x-12)

Since this is a test/homework, I'll give you a hint.

A triangle always is 180 degrees. If you add up all the sides, it should be 180.

A horizontal line is 180, if you add up the two sides (or the "line" that is crossing through the horizontal one) it'll be 180.

Just think of it like this: 180 is king. No matter what you add together, if its not 180, its wrong.

The standard matrix A is [ (1/2, √3/2) (√3/2, -1/2) ]

To find the standard matrix of a linear transformation, we need to find the images of the standard basis vectors under the transformation.

The standard basis vectors in R2 are (1,0) and (0,1). Let's find their images under T.

The image of (1,0) under a 30∘ clockwise rotation is (√3/2, 1/2). The image of this under reflection through the line y=x is (1/2, √3/2).

The image of (0,1) under a 30∘ clockwise rotation is (-1/2, √3/2). The image of this under reflection through the line y=x is (√3/2, -1/2).

The standard matrix of T is then the matrix whose columns are the images of the standard basis vectors:

A = [ (1/2, √3/2) (√3/2, -1/2) ]

= \(\left[\begin{array}{cc}1/2&\sqrt{3} /2\\\sqrt{3} /2&-1/2\end{array}\right]\)

Answe: there is no pic

Step-by-step explanation:

The requried position of point B on the number line is 1/4 or 0.25.

Since point B represents the number 0.25 on the number line, its position can be described as 0.25 units to the right of 0 or as 0.25 units to the left of 0.5.

Alternatively, we can describe its position as a fraction or mixed number using the length of the number line as the denominator. If the number line extends from 0 to 1, then the position of point B can be expressed as:

B = 0 + 0.25 = 1/4

Therefore, the position of point B on the number line is 1/4 or 0.25.
