I am having trouble with this problem

The value of  (-3/4[tex])^{-4[/tex] is 256/81.

Exponents and powers are ways used to represent very large numbers or very small numbers in a simplified manner.

For example, if we have to show 3 x 3 x 3 x 3 in a simple way, then we can write it as [tex]3^4[/tex], where 4 is the exponent and 3 is the base. The whole expression 34 is said to be power.

We have to find the value of (-3/4[tex])^{-4[/tex]

First of all make the power positive by reciprocate the number

= (-3/4[tex])^{-4[/tex]

= (-4/ 3 [tex])^4[/tex]

Now, expanding the number we get

= (-4 x -4 x -4 x -4) / (3 x 3 x 3 x 3)

= 256 / 81

Answer:

x = - 191/28

Step-by-step explanation:

14 (8x + 56) = 20

112x + 784 = 20

112x = 20 - 784

112x = - 764

x = - 764/112

x = - 191/28

Answer:

Here are a few equivalent equations:

112x + 784 = 20

112x = -764

x = -6.82

Step-by-step explanation:

14(8x + 56) = 20

Answer:

15

Step-by-step explanation:

mean = 20 + 30 + 39 + 44 + 52 /5

mean = 185 ÷ 5

mean = 37

52 - 37 = 15

The mean of the data set is 37. The number 52 deviates from the mean by 15. Key concepts include mean, deviation, and data set.

The first step in answering the question 'How much does 52 deviate from the mean?' is to calculate the mean (also called the average) of the data set. We do this by adding together each of the numbers in the data set and then dividing by the number of elements. The calculation looks like this: (20 + 30 + 39 + 44 + 52) / 5 = 37. Then, to determine how much 52 deviates from the mean, subtract the mean from 52. This gives us: 52 - 37 = 15. So, 52 deviates from the mean by 15. Mean, deviation, and data set are key mathematical concepts related to this question and answer.

Answer:

Step-by-step explanation:-15/4

-15/4

Answer:

-0.14

Step-by-step explanation:

First eliminate the parenthesis:

6( 4x + 5) = 3(x + 8) + 3 =>

24x + 30 = 3x + 24 + 3

Then group x terms on the left and constants on the right

24x - 3x = 24 + 3 - 30

21x = -3

Divide by 21 and simplify:

x = -3/21 = -1/7 ≈ -0.14

Answer:

- 1/7

Step-by-step explanation:

6(4x + 5) = 3(x + 8) + 3

Expand the brackets

6 X 4x + 6 x 5 = 3 X x + 3 X 8 + 3

24x + 30 = 3x + 24 + 3

24x + 30 = 3x + 27

Subtract 30 from both sides to eliminate 30 on the left side

24x + 30 - 30 = 3x + 27 - 30

24x = 3x - 3

Subtract 3x from both sides to eliminate bring all variables to one side

24x - 3x = 3x - 3x - 3

21x = -3

Divide both sides by 21 to isolate x

21x/21 = -3/21

x = -1/7

x = - 1/7

It would be A or < since 54 is positive and -26 isn't, that makes 54 greater than -26.

The temperature at the top of the mountain is -15.2°C.

The solution to the problem:

Given:

The temperature at the base of the mountain is -4.4°C.

The temperature at the top of the mountain is 10.8°C less than the temperature at the base of the mountain.

Objective:

Determine the temperature at the top of the mountain.

Solution:

Let x be the temperature at the top of the mountain. We know that the temperature at the top of the mountain is 10.8°C less than the temperature at the base of the mountain, so we can write the following equation:

x = -4.4 - 10.8

Simplifying the right side of the equation, we get:

x = -15.2°C

Step-by-step explanation:

We have been given that the painting is 3 times as long as it is tall.The expression [tex]2(x+3x)[/tex] represents the perimeter of the painting, where x represents the length of the short side of the painting in feet.

To find the the amount of framing needed when short side of the painting measures 2.6 feet, we will substitute [tex]x=2.6[/tex] in our given expression.

We can simplify our expression as:

[tex]2(x+3x)=2(4x)[/tex]

[tex]2(4x)=2(4\times 2.6)[/tex]

[tex]2(4x)=2(10.4)[/tex]

[tex]2(4x)=20.8[/tex]

Therefore, a total of 20.8 feet of framing is needed.

By using the given expression 2(x+3x) and substituting the short side measurement of 2.6 feet, we find that the total framing needed is 20.8 feet for the large rectangle painting.

To calculate the total framing needed for the painting, we start by using the expression 2(x+3x), which represents the perimeter of the painting. Given that the short side (x) of the painting measures 2.6 feet, we substitute x with 2.6 feet in the expression, resulting in 2(2.6 feet + 3(2.6 feet)), which simplifies to 2(2.6 feet + 7.8 feet). This gives us 2(10.4 feet), equaling 20.8 feet of framing that is needed.

The dimensions of the painting are based on the fact that the painting is three times as long as it is tall.

The short side is the height of the painting, and the long side, therefore, is 3 times the short side. Since the painting is a rectangle, we apply the formula for the perimeter of a rectangle, which is P = 2(length + width), to get the overall framing length.

Answers and Step-by-step explanations:

We need to use FOIL (first, outer, inner, last) to solve this.

The first terms of each of the two expressions (2x - 1) and (2x + 6) are 2x and 2x. Multiply these together: 2x * 2x = 4x².

The outer terms are 2x and 6, respectively, and their product is 2x * 6 = 12x.

The inner terms are -1 and 2x, respectively, and their product is -1 * 2x = -2x.

The last terms are -1 and 6, respectively, and their product is -1 * 6 = -6.

Add these together:

4x² + 12x + (-2x) + (-6) = 4x² + 10x - 6

Let's see if this is equal to (1x - 2) * (6 + 2x) by expanding this one using FOIL as well:

The first terms are 1x and 6, respectively, and their product is 1x * 6 = 6x.

The outer terms are 1x and 2x, respectively, and their product is 1x * 2x = 2x².

The inner terms are -2 and 6, respectively, and their product is -2 * 6 = -12.

The last terms are -2 and 2x, respectively, and their product is -2 * 2x = -4x.

Add all these up:

6x + 2x² + (-12) + (-4x) = 2x² + 2x - 12

Clearly, 2x² + 2x - 12 is NOT the same as 4x² + 10x - 6, so (2x - 1)(2x + 6) is not equal to (x - 2)(6 + 2x).

Step-by-step explanation:

Divide each number by 1/2 or times by .5

Quadrant one: positive x and positive y. (5,6)

Quadrant two: negative x and positive y. (-5,6)

Quadrant three: negative x and negative y. (-5,-6)

Quadrant four: positive x and negative y. (5,-6)

the y-axis goes up and down so im guessing the x coordinates will be 0 and the y will be whatever you want it to be. the same goes for the x-axis excepted switched around.

Apologies if I got any of these wrong, and please comment if you are confused so I can explain more.

1.) First quadrant: x > 0, y > 0.

2.) Second quadrant: x < 0, y > 0.

3.) Third quadrant: x < 0, y < 0.

4.) Fourth quadrant: x > 0, y < 0.

5.) On y-axis: x = 0, y ≠ 0.

6.) On x-axis: x ≠ 0, y = 0.

1.) Points in the First Quadrant: In the first quadrant, both x and y coordinates are positive. Therefore, the coordinates of points A and B might be of the form (x, y) where x > 0 and y > 0. For instance, point A might be (3, 4) and point B might be (5, 7).

2.) Points in the Second Quadrant: In the second quadrant, x coordinates are negative and y coordinates are positive. Thus, the coordinates of points D and E might be of the form (-x, y) where x > 0 and y > 0. For example, point D might be (-2, 3) and point E might be (-6, 8).

3.) Points in the Third Quadrant: In the third quadrant, both x and y coordinates are negative. Therefore, the coordinates of points G and H might be of the form (-x, -y) where x > 0 and y > 0. For instance, point G might be (-4, -5) and point H might be (-7, -9).

4.) Points in the Fourth Quadrant: In the fourth quadrant, x coordinates are positive and y coordinates are negative. Thus, the coordinates of points J and K might be of the form (x, -y) where x > 0 and y > 0. For example, point J might be (3, -2) and point K might be (8, -5).

5.) Points on the Y-Axis: Points on the y-axis have x coordinates equal to 0, and their y coordinates can be positive or negative. Thus, the coordinates of points M and N might be of the form (0, y). For instance, point M might be (0, 4) and point N might be (0, -7).

6.) Points on the X-Axis: Points on the x-axis have y coordinates equal to 0, and their x coordinates can be positive or negative. Thus, the coordinates of points Q and R might be of the form (x, 0). For example, point Q might be (5, 0) and point R might be (-3, 0).

Answer:

1<y≤8

Step-by-step explanation:

step 1

The number is y and it is greater than one.

The sign for greater than in mathematics is '>'

Therefore, we can write

y>1

And it means 1 is less than y

Less than = <

1<y

Step 2

y is less than or equal to 8. In mathematics, the 'less than or equal to' sign is '≤'

Therefore, we can write

y≤8

Step 3

We then combine these two inequalities

1<y≤8

Final answer:

The inequality 1 < y ≤ 8 represents a number y that is greater than 1 and less than or equal to 8.

Explanation:

An inequality representing the statement 'A number y is greater than 1 and is less than or equal to 8' can be expressed as:

1 < y ≤ 8

This inequality signifies that y is greater than 1 (1 < y) and at the same time, less than or equal to 8 (y ≤ 8), fulfilling both conditions simultaneously.

Segments parallel to XT: YU, ZV, WS

Segments parallel to ZY: VU, WX

Segments parallel to ZS: None

Plane parallel to plane STU: WXY

Plane parallel to plane UVZ: TSW

All segments skew to SW: WX, ST

All segments skew to UT: UY, TX

Step-by-step explanation:

Let's begin by explaining the following:

Two line segments are parallel only if their slopes are identical, allowing them to never intersect.

Hence, according to this definition we have:

Segments parallel to XT: YU, ZV, WS

Segments parallel to ZY: VU, WX

Segments parallel to ZS: None

Now, if we go to the three-dimensional space, two planes are parallel, when they do not share any line, which allows them to never cross in space.

Hence, according to this definition we have:

Plane parallel to plane STU: WXY

Plane parallel to plane UVZ: TSW

Two lines are skew if and only if they are not in the same plane (also known as not coplanar). So, if two lines are not coplanar, they are not parallel and cannot intersect, either.

Hence, according to this definition we have:

All segments skew to SW: WX, ST

WZ and SV do not match the condition, since they are in the same plane where SW is,

All segments skew to UT: UY, TX

UV and  ST do not match the condition, since they are in the same plane where UT is.

The following answers can be given as the solution to the given questions:

a) All segments parallel to XT:  YU, ZV, WS

b) All segments parallel to ZY:  VU, WX

c) All segments parallel to ZS:  YT

d) A plane parallel to plane STU: WXY

e) A plane parallel to plane UVZ:  TSW

f) All segments skew to SW:  ZY, VU, XY, UT

g) All segments skew to UT:  SW, WX, VZ, ZY

To give the appropriate answers to the given questions, the following terms must be understood.

i. Parallel lines: Two or more lines are parallel if and only if they do not meet even when extended to infinity.

ii. Skew lines: Two or more skew lines are lines that are neither parallel nor intersecting.

iii. Plane: This is flat surface which can either be in x-axis, y-axis or z-axis.

Therefore, the answers to each of the questions are:

a) All segments parallel to XT:  YU, ZV, WS

b) All segments parallel to ZY:  VU, WX

c) All segments parallel to ZS:  YT

d) A plane parallel to plane STU: WXY

e) A plane parallel to plane UVZ:  TSW

f) All segments skew to SW:  ZY, VU, XY, UT

g) All segments skew to UT:  SW, WX, VZ, ZY

Answer:

x^2 + (y – 3)^2 = 36

Step-by-step explanation:

The standard equation of a circle with center at (h, k) and radius r is

(x - h)^2 + (y - k)^2 = r^2.

If the center lies on the y-axis, then h = 0:  (x - 0)^2 + (y - k)^2 = r^2

If the circle diameter is 12, then the circle radius is 6, and so r^2 = 36

So, among the given equations, your

x^2 + (y – 3)^2 = 36 is correct (but only if you use " ^ " for exponentiation).

The equations that represent circles with a diameter of 12 units and a center on the y-axis are x² + (y - 6)² = 36 and x² + (y + 6)² = 36.

The equations that represent circles with a diameter of 12 units and a center on the y-axis are:

To determine if an equation represents a circle, we need to check if the equation follows the standard form of a circle equation, which is (x - h)² + (y - k)² = r², where (h, k) is the center and r is the radius. In this case, since the center lies on the y-axis, the x-coordinate of the center is 0, and we only need to consider the y-coordinate.

In triangle EFG, the right angle is at F. Using the Pythagorean theorem, we can find the length of the hypotenuse and use it to calculate the trigonometric ratios.

In triangle EFG, the right angle is at F. Given that EG = 8 and FG = 2, we can use the Pythagorean theorem to find the length of EF. Using the formula a^2 + b^2 = c^2, where a and b are the lengths of the legs and c is the length of the hypotenuse, we can calculate that EF = sqrt((EG^2) + (FG^2)) = sqrt((8^2) + (2^2)) = sqrt(64 + 4) = sqrt(68).

To find tan E, we can use the ratio of the opposite side (FG) to the adjacent side (EG). tan E = FG/EG = 2/8 = 1/4.

To find sin G, we can use the ratio of the opposite side (FG) to the hypotenuse (EF). sin G = FG/EF = 2/sqrt(68).

To find sec G, we can use the ratio of the hypotenuse (EF) to the adjacent side (EG). sec G = EF/EG = sqrt(68)/8.
