The points that show the triangle when it is translated two units down are (2, 3) (0, 1), and (2, 1).

A function, f, that maps to itself are known as a transformation, or f: X- X. The pre-image X becomes the picture X following the transformation. This transformation can use any operation, or a combination of operations, including translation, rotation, reflection, and dilation. Translation, rotation, reflection, and dilation can all be used to move a function in one direction or another.

Given that the initial coordinate of triangles ABC are at points

(2, 1), (0, -1), (2, -1).

The coordinate base of the triangle must be (2, 1) and (2, -1)

When the triangle is translated two units down.

2 will be added to all its y coordinates. While the x coordinate remains the same

The new coordinate will be

(2, 2+1), (0, 2-1), (2, 2-1)

(2, 3) (0, 1) and (2, 1)

Hence the new coordinates are (2, 3) (0, 1), and (2, 1).

With a total perimeter of 150 inches and a width of 42 inches, the length was calculated to be 33 inches, option D.

To determine how long the quilt is, we need to calculate the perimeter of the rectangular quilt and then solve for the missing length. Since Annita needs 150 inches of lace, we know this is the total perimeter (P) of the quilt. The quilt is 42 inches wide. The formula for the perimeter of a rectangle is P = 2(length) + 2(width). We can set up the equation as 150 = 2(length) + 2(42).

Now let's solve for the length (L):

The length of the quilt is 33 inches, which corresponds to option D.

The length of the quilt is 33 inches.

The correct option is (D).

To find the length of the quilt, we need to use the formula for the perimeter of a rectangle, which is given by:

[tex]\[ \text{Perimeter} = 2 \times (\text{Length} + \text{Width}) \][/tex]

Given that the width of the quilt is 42 inches and Annita needs 150 inches of lace to go around the entire quilt, we can set up the equation as:

[tex]\[ 150 = 2 \times (\text{Length} + 42) \][/tex]

Now, let's solve for the length [tex](\( \text{Length} \)):[/tex]

[tex]\[ 150 = 2 \times (\text{Length} + 42) \][/tex]

[tex]\[ 75 = \text{Length} + 42 \][/tex]

Subtract 42 from both sides:

[tex]\[ 75 - 42 = \text{Length} \][/tex]

[tex]\[ \text{Length} = 33 \][/tex]

So, the length of the quilt is 33 inches. Therefore, the answer is option D. 33 inches.

Answer:

362880 ways

Step-by-step explanation:

In this case, the order does matter therefore to know how many ways it can be aligned, we must resort to permutations.

The formula for permutations is:

P = n!

we know that there are 9 trumpet players, therefore:

P = 9!

P = 362880

So there are 362,880 ways to line up

Using the Pythagorean theorem, the diagonal distance from one corner pocket to the diagonally opposite corner pocket on an 8 foot by 4 foot pool table is about 8.94 feet.

To determine the distance from one corner pocket to the diagonally opposite corner pocket on a pool table, we can use the Pythagorean theorem because the pool table forms a rectangle and the diagonal forms a right triangle with the length and width of the table. Given the dimensions of the pool table as 8 feet long and 4 feet wide, we can label these as the two sides of the right triangle.

The Pythagorean theorem states that for a right triangle with sides of lengths a, b, and hypotenuse c, the relationship between these sides is [tex]a^2 + b^2 = c^2[/tex]. Substituting the given values, we have:

Therefore, the diagonal distance from one corner pocket to the diagonally opposite corner pocket is about 8.94 feet.

This graph represents function of y = 3x²+7x+2, which is correct option(D).

A parabola is a U-shaped curve this is drawn for a quadratic function,

f(x) = ax² + b x + c. The graph of the parabola is downward (or opens down), when the price of a is much less than 0, a < 0. The graph of the parabola is upward (or opens up) when the value of a is more than 0, a > 0.

Given function, y = 3x²+7x+2

Compare the given function to f(x) = ax² + b x + c ,

The graph of given function is upward (or opens up) because the value of 3 is more than 0, 3 > 0.

The x-intercept of given function are (-1/3, 0) and (-2,0)

The y-intercept of given function is (0,2)

Here is a graph represents function of y = 3x²+7x+2

brainly.com/question/4074088

#SPJ5

The correct option is A. Graph A. It shows an upward-opening parabola with a vertex and y-intercept that match the derived values.

1. Direction of the Parabola : Since the coefficient of [tex]\( x^2 \)[/tex] (which is [tex]3[/tex]) is positive, the parabola opens upwards.

2. Vertex : The vertex of a parabola in the form [tex]\( y = ax^2 + bx + c \)[/tex] can be found using the formula for the x-coordinate of the vertex, [tex]\( x = -\frac{b}{2a} \)[/tex]

For the given function:

[tex]\[ a = 3, \quad b = 7 \][/tex]

So,

[tex]\[ x = -\frac{7}{2 \times 3} = -\frac{7}{6} \][/tex]

Next, we find the y-coordinate of the vertex by plugging [tex]\( x = -\frac{7}{6} \)[/tex] back into the equation:

[tex]\[ y = 3\left(-\frac{7}{6}\right)^2 + 7\left(-\frac{7}{6}\right) + 2 \][/tex]

Let's compute that:

[tex]\[ y = 3 \times \frac{49}{36} - \frac{49}{6} + 2 \][/tex]

[tex]\[ y = \frac{147}{36} - \frac{294}{36} + \frac{72}{36} \][/tex]

[tex]\[ y = \frac{147 - 294 + 72}{36} \][/tex]

[tex]\[ y = \frac{-75}{36} \][/tex]

[tex]\[ y = -\frac{25}{12} = -2.083 \][/tex]

Thus, the vertex is approximately at [tex]\(\left( -\frac{7}{6}, -\frac{25}{12} \right)\)[/tex]

3. Y-Intercept : This is the value of [tex]\( y \)[/tex] when [tex]\( x = 0 \)[/tex]

[tex]\[ y = 3(0)^2 + 7(0) + 2 = 2 \][/tex]

The graph should cross the y-axis at [tex]\( y = 2 \)[/tex]

Now, let's compare these features with the provided graphs:

The parabola should open upwards.

The y-intercept should be [tex]2[/tex].

The vertex should be approximately at [tex]\( \left( -\frac{7}{6}, -\frac{25}{12} \right) \)[/tex]

Answer:

24

Step-by-step explanation:

cos(x) is just a trigonometric function. To find it on a right triangle, you take the "adjacent" side, which should be the side next to the angle x, and divide it by the hypotenuse.

In this case, the adjacent side is 12. We don't know the hypotenuse, but we can figure it out using the Pythagorean Theorem: [tex]\sqrt{9^{2}+12^{2}}[/tex] = [tex]\sqrt{225}[/tex] = 15. So, the hypotenuse is 15.

Thus, cos(x) = 12/15 = 4/5. We want 30 * cos(x), so we get: 30 * (4/5) = 24, and that is our answer.

Answer:

24

Step-by-step explanation:

From the mnemonic SOHCAHTOA you would know that cos x = adjacent/hypotenuse.

Adjacent side is given as 12, but we must calculate the hypotenuse.

For that we use Pythagoras.

hypotenuse = √(9²+12²) = 15

Now you can calculate

30×cos(x) = 30×12/15 = 24

The value of the given expresion is zero.

Step-by-step explanation:

I am assuming that, your exprssion is

[tex] {( - 1)}^{3} =-1[/tex]

[tex] {( - 1)}^{5} =-1[/tex]

[tex] {( - 1)}^{7} =-1[/tex]

If r is odd, then

[tex] {( - 1)}^{r} = - 1[/tex]

The measure of angle B in triangle ABC is 63.9°. Hence, Bethany has done a mistake in step 2.

Given that, in the triangle ABC, AC=4.1 cm, AB=4.5 cm and BC=2.7 cm.

We need to find the measure of angle B.

The trigonometric function to find the angle in the triangle is b²=a²+c²-2ac cosB.

Now, (4.1)²=(4.5)²+(2.7)²-2×4.5×2.7 cosB.

⇒16.81=20.25+7.29-24.3 cosB

⇒16.81-27.54=-24.3 cos B

Answer:

C) 26 blocks

Step-by-step explanation:

For the firs one draw a dot where they start. Then draw a line going down and label it 10. Next draw a line going left and label it 24. Connect the end of those who lines to form a triangle. Now we can use the pythagorean theory.

a^2 + b^2 = c^2

a^2= side one (you choose)

b^2= side two (whichever side you didn't use out of the two)

c^2= the hypotenuse( this is the diagonal line you drew connecting the two lines at the end)

10^2 + 24^2 =c^2

100 + 576 =c^2

676=c^2     Since the C is still squared we have to squareroot both sides. This will cancel oout the ^2 on the C.

[tex]\sqrt{676} =\sqrt{c^2}[/tex]   Solve.

You are going to want to use the compound interest formula, which is shown below.

[tex]P(1+\frac{r}{n} )^{nt}[/tex]

P = initial balance

r = interest rate

n = number of times compounded annually

t = time

Now lets plug in the values into the equation.
