Step-by-step explanation:

I'm going to try to explain this as easy as possible. What I did was take the original shape and divide it by the new shape. For this question, I solved it by dividing 32(the original base) by 4(the new base) and got 8. So the scale factor of the reduction was 1/8.

Answer:

x = 9, GH = 21, CD = 17

Step-by-step explanation:

Quadrilateral CDEF is a trapezoid in which G and H are mid points of the sides CF and DE respectively.

In a trapezoid, segment joining the mid points is equal to the half of the sum of the parallel sides.

[tex] \therefore \: GH = \frac{1}{2} (CD + FE) \\ \\ \therefore \:3x - 6 =\frac{1}{2} (2x - 1 + 25) \\ \\ \therefore \:3x - 6 =\frac{1}{2} (2x + 24) \\ \\ \therefore \:3x - 6 =\frac{1}{2} \times 2 (x + 12) \\ \\ \therefore \:3x - 6 = x + 12 \\ \\ \therefore \:3x - x = 12 + 6 \\ \\ \therefore \:2x = 18 \\ \\ \therefore \:x = \frac{18}{2} \\ \\ \huge\red{ \boxed{\therefore \:x = 9}} \\\\ \because \overline{GH} = 3x - 6 \\ \\\therefore \:\overline{GH} =3 \times 9 - 6 \\ \\ \therefore \:\overline{GH} =27 - 6 \\ \\ \huge\purple{ \boxed{\therefore \:\overline{GH} =21}} \\ \\ \because\overline{CD} = 2x - 1 \\\\ \therefore \:\overline{CD} =2 \times 9 - 1 \\ \\ \therefore \:\overline{CD} =18 - 1 \\ \\ \huge\pink{ \boxed{\therefore \:\overline{CD} =17}} \\ \\ [/tex]

Answer: 30

Step-by-step explanation:

Let the number be y

Add 5 to me

Y+5............equ1

Divide by 7

Y+5/7

Add 12

Y+5/7+12

Subtract 7

(Y+5)/7+(12-7)=10

12-7=5

Substitute

(Y+5)/7+5=10

Find the lowest common multiple

((Y+5)+7(5))/7=10

(Y+5)+35)/7=10

Cross multiply

Y+5+35=70

Y+40=70

Y=70-40

Y=30

The unknown number is 30

Answer: $1.25:1yd

Step-by-step explanation:

Take 10 and divide it by 8, which should give you 1.25.

This is the answer, the ratio of dollars to yard of fabric is $1.25 per 1 yard of fabric.

To check this, simply multiply both sides by 8 and you should get the original ratio of $10 for 8 yards of fabric.

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

To solve the equation 2e^3x = 400, we isolate e^3x and then use the natural logarithm to solve for x, which gives x ≈ 2.995 when rounded to three decimals.

The question asks us to solve the equation 2e^3x = 400 for the variable x. First, we isolate e^3x by dividing both sides of the equation by 2. We get: e^3x = 400/2 which is e^3x = 200. Finding x means solving for 'x' in an exponential equation, which involves using the natural logarithm.

So, our equation becomes: x = ln(200)/3. Using a calculator, x ≈ 2.995 when rounded to three decimals.

Step-by-step explanation:

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

#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:

The value of the given expresion is zero.

Step-by-step explanation:

I am assuming that, your exprssion is

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

where r is an integer greater than 1.

Let us see what a negative base 1 to an off exponent give us:

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

[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]

This implies that:

[tex] {( - 1)}^{r} + 1 = - 1 + 1 = 0[/tex]

The value of the given expresion is 0.

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

⇒cos B=0.44

⇒B=63.9°

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.

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).
