The result in scientific notation is 2 x 10³.

Given,

(5 × 10^-3) (4 × 10^5)

We need to write in scientific notation.

What is scientific notation?

When a large number is written between 1 and 10 with a power of 10.

Multiply (5 × 10^-3) (4 × 10^5).

= (5 x 1/10^3)x (4 x 100000)

= 5 / 1000 x 4 x 100000

=  20 x 100

= 2 x 1000

= 2 x 10³

2 is a number between 1 and 10 and 10^3 is a power of 10.

Thus the result in scientific notation is 2 x 10³.

The length of the ladder needed to reach an electric box 28 feet up is 31.2 feet.

The ladder, the distance from the wall to the base of the ladder and the distance from the ground to the electric box forms a right angled triangle.

Trigonometric ratios shows the relationship between the sides and angles of a right angled triangle.

Let x represent the length of the ladder, hence:

sin(64) = 28 feet/x

x = 28 feet / sin(64)

x = 31.2 feet

Hence the length of the ladder needed to reach an electric box 28 feet up is 31.2 feet.

Two variables that move in opposite directions are said to be inversely related.

A negative correlation is a relationship between two variables that move in opposite directions. In other words, when variable A increases, variable B decreases. A negative correlation is also known as an inverse correlation.

The concept of negative correlation is important for investors or analysts who are considering adding new investments to their portfolio. When market uncertainty is high, a common consideration is re-balancing portfolios by replacing some securities that have a positive correlation with those that have a negative correlation.

Here are some common examples of a negatively correlated relationship between assets:

1. Oil prices and airline stocks

2. Gold prices and stock markets (most of the time, but not always)

3. Any type of insurance payoff

The vertical compression by a factor of 0.5, reflection across the y-axis, vertical translation 3 units down, vertical stretch by a factor of 0.5, reflection across the x-axis, vertical translation 3 units up, and vertical translation 0.5 units down.

1. Vertical compression by a factor of 0.5: This means that the graph will be compressed vertically, making it narrower. Each y-coordinate of the original graph is multiplied by 0.5.

2. Reflection across the y-axis: This means that the graph will be flipped horizontally. Each x-coordinate of the original graph is multiplied by -1.

3. Vertical translation 3 units down: This means that the entire graph will be shifted downwards by 3 units. Each y-coordinate of the original graph is decreased by 3.

4. Vertical stretch by a factor of 0.5: This means that the graph will be stretched vertically, making it taller. Each y-coordinate of the graph after vertical compression is multiplied by 2.

5. Reflection across the x-axis: This means that the graph will be flipped vertically. Each y-coordinate of the graph after vertical compression and stretching is multiplied by -1.

6. Vertical translation 3 units up: This means that the entire graph will be shifted upwards by 3 units. Each y-coordinate of the graph after vertical compression, stretching, and reflection across the x-axis is increased by 3.

7. Vertical translation 0.5 units down: This means that the entire graph will be shifted downwards by 0.5 units. Each y-coordinate of the graph after vertical compression, stretching, reflection across the x-axis, and vertical translation upwards is decreased by 0.5.

In summary, the given transformations result in a graph that is vertically compressed by a factor of 0.5, reflected across the y-axis, vertically translated 3 units down, vertically stretched by a factor of 0.5, reflected across the x-axis, vertically translated 3 units up, and finally vertically translated 0.5 units down.

Answer:

After she distribute the \(x\) and \(-1\) by \(-5\), the after you get \(-5x - 5 > -7x + 19\), she put a negative \(5\) instead of a positive \(5\), and would be written as\(-5x + 5 > -7x + 19\).

Step-by-step explanation:

Solve the inequality for the correct solution:

\(-5(x - 1) > -7x + 19\)

-Use Distributive Property:

\(-5(x - 1) > -7x + 19\)

\(-5x + 5 > -7x + 19\)

-Take \(7x\) and add it to \(-5x\):

\(-5x + 5 + 7x > -7x + 7x + 19\)

\(2x + 5 > 19\)

-Subtract \(5\) to both sides:

\(2x + 5 - 5 > 19 - 5\)

\(2x > 14\)

-Divide both sides by \(2\):

\(\frac{2x}{2} > \frac{14}{2}\)

\(\boxed {x > 7}\)

The average distance that the airplane covered in three flights is 2036 kilometers, time in trip from Hongkong to Manila is 1.468 hours, time in trip from Singapore to Manila is 3.146 hours, time in trip from Korea to Manila is 3.422 hours.

Given the distance that an airplane covered in three different trips:

Hongkong-Manila: 1116 kilometers, Singapore-Manila: 2391 kilometers,

Korea-Manila: 2601 kilometers.

We are required to find the average distance traveled by the airplane in the three trips, the time it took in each trip if the speed of airplane is 760 km/h and the trip that took the longest time to travel.

Average distance that airplane travelled in the three trips=(1116+2391+2601)/3

=6108/3

=2036 kilometers

We know that speed=distance/time.

Time=Distance/speed

Time in trip from Hongkong to Manila=1116/760=1.468 hours

Time in trip from Singapore to Manila=2391/760=3.146 hours

Time in trip from Korea to Manila=2601/760=3.422 hours

We can observe that the trip from Korea to Manila took longest time to travel.

Hence the average distance that the airplane covered in three flights is 2036 kilometers, time in trip from Hongkong to Manila is 1.468 hours, time in trip from Singapore to Manila is 3.146 hours, time in trip from Korea to Manila is 3.422 hours and the trip from Korea to Manila took longest time to travel.

The expression of ⁴√(81x³y⁴z⁸) with rational exponents is: 3x(¾)yz²

The 8 laws of exponents can be listed as follows:

Zero Exponent Law: a^(0) = 1.

Identity Exponent Law: a^(1) = a.

Product Law: a^m × a^n = a^(m+n)

Quotient Law: a^m/a^n = a^(m - n)

Negative Exponents Law: a^(-m) = 1/a^(m)

Power of a Power: (a^m)^n = a^(mn)

Power of a Product: (ab)^m = a^m*b^m

Power of a Quotient: (a/b)^m = a^m/b^m

We are given the algebra expression as:

⁴√81x³y⁴z⁸

Answer:

Step-by-step explanation:

Problem 1

We start at 8 on the number line. Then we move 7 units to the left to arrive at 1

So 8 + (-7) = 1

This is the same as saying 8 - 7 = 1.

========================================================

Problem 2

We start at -3. We'll move 5 units to the left to get to -8

So -3 + (-5) = -8

========================================================

Problem 3

Start at 7. Then move 7 units to the left to get to 0

7 + (-7) = 7 - 7 = 0

========================================================

Problem 4

Start at -2 and move 12 units to the right to get to 10 on the number line.

-2 + 12 = 10

========================================================

Problem 5

We start with -8 and move 10 spaces to the right to get to 2 on the number line.

-8 + 10 = 2

The vertex form of the equation is y = (x - 3)² - 4, which corresponds to option OD.

To convert the given equation from standard form to vertex form, we need to complete the square.

The vertex form of a parabola's equation is y = a(x-h)² + k, where (h, k) represents the vertex of the parabola.

Given equation: y = x² - 6x + 14

Move the constant term to the right side:

y - 14 = x² - 6x

Complete the square by adding and subtracting the square of half the coefficient of x:

y - 14 + 9 = x² - 6x + 9 - 9

Group the terms and factor the quadratic:

(y - 5) = (x² - 6x + 9) - 9

Rewrite the quadratic as a perfect square:

(y - 5) = (x - 3)² - 9

Simplify the equation:

y - 5 = (x - 3)² - 9

Move the constant term to the right side:

y = (x - 3)² - 9 + 5

Combine the constants:

y = (x - 3)² - 4

- Point A: (2, 0, 0)

- Point B: (2, 3, 0)

- Point C: (2, 0, 4)

- Point D: (2, 3, 4)

- Point E: (0, 3, 0)

- Point F: (0, 3, 4)

- Point G: (0, 0, 4)

- Point H: (0, 0, 0)

In the rectangular prism, the x-coordinate represents the distance along the x-axis, the y-coordinate represents the distance along the y-axis, and the z-coordinate represents the distance along the z-axis.

Point P, given as (2, 3, 4), has x = 2, y = 3, and z = 4. By using these values, we can determine the coordinates of the other points in the rectangular prism.

The points labeled A, B, C, D, E, F, G, and H represent the vertices of the prism. Point A has the same x-coordinate as P but is located at y = 0 and z = 0.

Similarly, points B, C, and D have the same x-coordinate as P but different y and z values. Points E, F, G, and H have different x-coordinates but the same y and z values.
