Answer:

1) [tex]5.8\times 10^7\text{ km}[/tex]

2) [tex]2.5\times 10^{-3}\text{ cm}[/tex]

Step-by-step explanation:

To put a value into scientific notation, we need to:

1) Move to decimal place such that our new value is between 1 and 10 and

2) Multiply by 10^n, where n is the amount of spaces moved. If we moved to the left, n is positive. If we move to the right, n is negative.

1)

We have:

[tex]58,000,000[/tex]

We can view this as:

[tex]58,000,000.0[/tex]

Our new value should be between 1 and 10.

58000000

So, let's move our decimal 7 places to the left. This gives us:

[tex]5.8000000[/tex]

Since we moved 7 to the left, we need to multiply by 10^7. Note that the 7 is positive. So:

[tex]=5.8000000\times 10^7[/tex]

We can remove the trailing zeros and add our unit:

[tex]=5.8\times 10^7\text{ km}[/tex]

2)

We have:

[tex]0.0025[/tex]

Our new value should be between 1 and 10. So, move the decimal places 3 units to the right. This yields:

[tex]2.5[/tex]

Since we moved 3 to the right, we need to multiply by 10^(-3). This time, note that our exponent is negative. So:

[tex]=2.5\times 10^{-3}[/tex]

Add our unit:

[tex]=2.5\times 10^{-3}\text{ cm}[/tex]

And we're done!

Step-by-step explanation:

1. 58,000,000 km

2. 0.0025 cm

write in scientific notation:

1)

it would be more easier to read a notation in every 3 decimal places like thousands, millions, billions, etc.

we have 58,000,000 (note where the comma is placed) count every 3 to the left. just multiply by 10^6.

= 58 x 10⁶ km

2) 0.0025 (move 3 decimal places to the right)

= 2.5 x 10⁻³ cm

Answer:

  FALSE

Step-by-step explanation:

√2 is both real and irrational. In infinite number of real numbers are irrational. The offered statement is False.

We know, volume of rectangular prism is given by :

[tex]V = lbh\\\\V=\dfrac{1}{2}\times 2\times 2\ ft^2\\\\V=2\ ft^2[/tex]

Volume of cubic box :

[tex]v=a^3\\\\v=(\dfrac{1}{2})^3\ ft^3\\\\v=\dfrac{1}{8}\ ft^3[/tex]

Number of cubes can be filled :

[tex]N=\dfrac{V}{v}\\\\N=\dfrac{2}{\dfrac{1}{8}}\\\\N=16[/tex]

Therefore, 16 cubes can be put in the bin.

Hence, this is the required solution.

Answer:

x = 12

Step-by-step explanation:

Given

5(x - 6) = 2(x + 3) ← distribute parenthesis on both sides

5x - 30 = 2x + 6 ( subtract 2x from both sides )

3x - 30 = 6 ( add 30 to both sides )

3x = 36 ( divide both sides by 3 )

x = 12

The reason for the last step in the given proof is option E; For parallel lines cut by a transversal, corresponding angles are congruent.

Angles that are of the same measurement are called congruent.

Suppose that two angles ∠A and ∠B are of the same measure, then

[tex]m\angle A = m\angle B[/tex]

is the notation to say that they are of the same measurement, where the small m shows that it's the measurement of the angles they're preceding.

We write the congruency between them as;

[tex]\angle A \cong \angle B[/tex]

The last step is as folows

∠JIK ≅∠IJL

For parallel lines cut by a transversal, corresponding angles are congruent.

Since the two angles are corresponding angles and the two parallel lines are cut by a transversal.

Answer: y= -x+3

Step-by-step explanation:

Answer:

When you perform translations, you slide a figure left or right, up or down. This means that on the coordinate plane, the coordinates for the vertices of the figure will change.

To graph a translation, perform the same change for each point.

You can identify a reflection by the changes in its coordinates. In a reflection, the figure flips across a line to make a mirror image of itself. Take a look at the reflection below.

Figures are usually reflected across either the

x−

or the

y−

axis. In this case, the figure is reflected across the

y−

axis. If you compare the figures in the first example vertex by vertex, you see that the

x−

coordinates change but the

y−

coordinates stay the same. This is because the reflection happens from left to right across the

y−

axis. When you reflect across the

x−

axis, the

y−

coordinates change and the

x−

coordinates stay the same. Take a look at this example.

In the figure above the coordinates for the upper-left vertex of the original figure are (-5, 5). After you reflect it across the

x−

axis, the coordinates for the corresponding vertex are (-5, -5). How about the lower-right vertex? It starts out at (-1, 1), and after the flip it is at (-1, -1). As you can see, the

x−

coordinates stay the same while the

y−

coordinates change. In fact, the

y−

coordinates all become the opposite integers of the original

y−

coordinates. This indicates that this is a vertical (up/down) reflection or a reflection over the

x−

axis.

In a horizontal (left/right) reflection or a reflection over the

y−

axis, the

x−

coordinates would become integer opposites. Let’s look at an example.

This is a reflection across the

y−

axis. Compare the points. Notice that the

y−

coordinates stay the same. The

x−

coordinates become the integer opposites of the original

x−

coordinates. Look at the top point of the triangle, for example. The coordinates of the original point are (-4, 6), and the coordinates of the new point are (4, 6). The

x−

coordinate has switched from -4 to 4.

You can recognize reflections by these changes to the

x−

and

y−

coordinates. If you reflect across the

x−

axis, the

y−

coordinates will become opposite. If you reflect across the

y−

axis, the

x−

coordinates will become opposite.

You can also use this information to graph reflections. To graph a reflection, you need to decide whether the reflection will be across the

x−

axis or the

y−

axis, and then change either the

x−

or

y−

coordinates.

The new coordinates form an equation with the original coordinate and the units of translation.

Transformation is changing the graph to a new one by Rotation, Reflection, Translation, and Dilation.

Rotation is a type of transformation of an object on an x-y plane, when an object is turned clockwise or anticlockwise by a certain angle, the object is said to be rotated.

The coordinate (x,y) changes to ( y, -x).

Reflection is to create a mirror image of the coordinate or the figure.

Dilation is to compress or enlarge the image by a scale factor.

The translation is to shift the coordinate or the figure, to the left, right, up, or down.

Let the original coordinates be ( x, y)

Then if the coordinates are translated by 2 units to the right and 2 units up, the new coordinates are:

( x+2, y+2)

The new coordinates are = Original coordinates ± Translation units.

Answer:

[tex]f(n) =4 + f(n-1) \\for\ n>2[/tex]

Step-by-step explanation:

Given

[tex]f(1)=2\\ f(2)= 6\\ f(3)= 10\\ f(4)= 14\\ f(5)= 18[/tex]

Required

Determine the formula

First, we need to solve common difference (d)

[tex]d = f(n) - f(n-1)[/tex]

Take n as 2

[tex]d = f(2) - f(2-1)[/tex]

[tex]d = 6 - 2[/tex]

[tex]d = 4[/tex]

Represent each function as a sum of the previous

[tex]f(1) = 2[/tex]

[tex]f(2) = 2 + 4 = f(1) + 4[/tex]

[tex]f(3) = 6 + 4 = f(2) + 4[/tex]

[tex]f(4) = 10 + 4 = f(3) + 4[/tex]

[tex]f(5) = 14 + 4 = f(4) + 4[/tex]

Represent the function as [tex]f(n)[/tex]

[tex]f(n) =f(n-1) + 4[/tex]
