What is 2.4 x 10^4 covert the number into standard notation

Answer:

w = -(5 u)/7

Step-by-step explanation:

Solve for w:

-w - 4 u = 6 w + u

Hint: | Isolate w to the left-hand side.

Subtract 6 w - 4 u from both sides:

-7 w = 5 u

Hint: | Solve for w.

Divide both sides by -7:

Answer: w = -(5 u)/7

Answer:

x=20

Step-by-step explanation:

45+4x=6x+5

45=2x+5

40=2x

20=x

x=20

Answer:

x = 20

Step-by-step explanation:

45 + 4x = 6x + 5

45 - 5 =6x - 4x

40 = 2x

x = 40/2

x = 20

Check:

45 + 4*20 = 6*20 + 5

45 + 80 = 120 + 5 = 125

Answer:

Mean = 81°F.

S. dev. = 5°F.

Step-by-step explanation:

When we have a set of data:

{x₁, x₂, ..., xₙ}

The mean can be calculated as:

M = (x₁ + x₂ ... + xₙ)/N

Where N is the number of data points that we have:

in this case the set is:

{ 74°F , 79°F , 76°F, 85°F, 87°F, 83°F, 86°F, 78°F }

So N = 8.

Then the mean is:

M = ( 74°F + 79°F + 76°F + 85°F + 87°F + 83°F + 86°F + 78°F )/8

M = 81°F.

Now, the standard deviation can be calculated as.

Sd =  √ ( (1/N)*∑(xₐ - M)^2)

where the summation is over xₐ, which represents a summation over all the points in the data set.

Then we can write the standard deviation as:

Sd = √(1/8)*√( (74°F - 81°F)^2 + (79°F - 81°F)^2 + (76°F - 81°F)^2 + (85°F - 81°F)^2 + (87°F - 81°F)^2 + (83°F - 81°F)^2 + (86°F - 81°F)^2 + (78°F - 81°F)^2)

Sd = 4.58°F.

That we should round up to 5°F (because our mean has no digits after the decimal point)

Steps to solve:

3 + 9 * 7 - 8 / 2

~Multiply

3 + 63 - 8 / 2

~Divide

3 + 63 - 4

~Add

66 - 4

~Subtract

62

Answer: vertical translation

Step-by-step explanation:

A function is even if:

f(x) = f(-x)

and a function is odd if:

f(-x) = -f(x).

Now, we want to find a translation that only affects the symmetry of an odd function (but not that one of the even function).

The correct answer will be a vertical translation, now let's prove it.

when we have a function f(x) and we want to transform it into g(x), such that g(x) is a vertical translation of (for example) A units up, we can write the relation as:

g(x) = f(x) + A.

Now, let's see if this preserves the symmetry of the original function.

1) if f(x) is even, then:

g(x) = f(x) + A

g(-x) = f(-x) + A

But we know that f(-x) = f(x)

then:

g(-x) = f(-x) + A = f(x) + A = g(x)

this means that g(x) is even, the symmetry of an even function is not affected by this transformation.

Now suppose that f(x) is odd.

Then:

g(x) = f(x) + A

g(-x) = f(-x) + A

and f(-x) = -f(x)

then:

g(-x) = f(-x) + A = -f(x) + A

and this is clearly different than g(x) = f(x) + A.

Then the odd symmetry is broken.

Answer:

[tex](x,y)\rightarrow(x-1,y+2)[/tex]

Step-by-step explanation:

One unit left would be subtracting 1 from the pre-image's x-value.

Two units up would be adding 2 to the pre-image's y-value.

The translation rule would be:

[tex](x-1,y+2)[/tex]

Hope this helps.

The coordinates after the translation of 1 unit left and 2 units up will be (x-1,y+2).

It is described as the alteration of the geometric body's form and coordinates. It is also known as a two-dimensional transformation. Rotation, translation, reflection, and gliding translation are just a few of the geometric transformations that may affect geometry.

It is given that the coordinates of the points are (x,y)

We have to find the coordinates after the translation of 1 unit left and 2 units up.

A sort of transformation called a translation involves moving each point in a figure the same distance in the same direction.

The final unit would be to deduct 1 from the x-value of the pre-image. The pre-y-value images would be increased by 2 by moving two units higher.

Thus, the obtained coordinates will be (x-1,y+2).

The question is incomplete.

The complete question is" if the coordinates of the points are (x,y). What will be the coordinates after the translation of 1 unit left and 2 units up?

Answer:

13620000

Step-by-step explanation:

Answer:

the answe is -4

Step-by-step explanation:

first you distribute the five to the numbers in the paranthesis

5(-2n+6)

-10n+30=70.

than we subtract 30 from the 30 and 70

-10n=40

Next we divide by 10 to 40 and -10n

n=-4

the reason it negative is because if you divide a negative and a positive it always make a negative.

Answer: -1

Step-by-step explanation:

To find the slope fo the line with the given points, you use the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].

[tex]m=\frac{-1-6}{8-1}=\frac{-7}{7} =-1[/tex]

Now, we know that the slope is -1.

Answer:

  24 cm

Step-by-step explanation:

Since the triangles are similar, their dimensions are proportional. The base DC is half the base AE, so we know the ratio of triangle heights is 1 : 2.

Then the bottom height (h) ratio to the overall height is ...

  h : 36 = 2 : (1+2) = 2 : 3 = 24 : 36

The height h is 24 cm.

Answer:

BCD

Step-by-step explanation:

The top rectangle is ABCD because of its vertices.  BCD is included in it.

The top plane represented by the BCD

In geometry, a plane is a flat surface that extends into infinity. It is also known as a two-dimensional surface. A plane has zero thickness, zero curvature, infinite width, and infinite length. It is actually difficult to imagine a plane in real life; all the flat surfaces of a cube or cuboid, flat surface of paper are all real examples of a geometric plane. We can see an example of a plane in which the position of any given point on the plane is determined using an ordered pair of numbers or coordinates. The coordinates show the correct location of the points on the plane.

As, per the figure we can say that the upper plane is made of plane ABCD.

So, among all the option BCD will be correct because BCD is part of ABCD.
