Answer:

8x^9

Step-by-step explanation:

(2x^3)^3 =

First, to raise a product to an exponent, raise eve3ry factor to the exponent.

Second, to raise a power to a power, multiply powers.

= 2^3 * (x^3)^3

= 8 * x^9

= 8x^9

Answer:

we conclude that:

Step-by-step explanation:

A dilation is a transformation which generates an image that is the same shape as the original object but in a different size.

The image can be obtained by multiplying the measure of the original object by a scale factor.

If the scale factor > 1, the image is stretched

If the scale factor < 1, the image is reduced

If the scale factor = 1, the image and object will be congruent

For example, if we multiply the measure of the coordinates of the vertex A(2, 2) of a triangle by a scale factor of 2, the image A' is stretched as the scale factor > 1.

Dilation with scale factor 2, multiply by 2.

A(2, 2) → (2(2), 2(2)) = A'(4, 4)

So, the image point A'(4, 4) is enlarged.

Dilation with scale factor ½, multiply by ½.

A(2, 2) → (2(1/2), 2(1/2)) = A'(1, 1)

So, the image point A'(1, 1) is reduced.

Therefore, we conclude that:

Function

We can see all 3 graphs have y-intercept of -2

Since the slope is negative, it is decreasing function, therefore possible options are A or C

Checking x-intercept and comparing with same of A and C

As we see it matches Option C, which is the answer

As a decimal, the answer is 1.83. As a fraction, it’s 11/6 and as a mixed number, it’s 1 5/6

Answer:

r minus 38 equals to 134 this might be m not certain

The correct equation is, [tex]r-38=134[/tex] and Rajesh have 172 crystals .

Let us consider that, Rajesh had r  crystals.

Mariana had 134  crystals in her collection.

Since, Rajesh has 38 more crystal than Marina . So , if we subtract 38 from crystals Rajesh have then both have equal number of crystals.

So,     [tex]r-38=134[/tex]

Now, find crystals present in Rajesh collection.

                   [tex]r-38=134\\\\r=134+38=172[/tex]

Thus, Rajesh have 172 crystals .

Answer:

all real numbers

Step-by-step explanation:

The graphs of positive and negative x^2 parabolas will always have a domain of all real numbers.  Even though you only have a portion of the graph and see a "restriction" on your domain values, it is incorrect to assume that the domain is limited to what you can see.  As the branches of the parabola keep going up and up and up, the values of x keep getting bigger and bigger and bigger.  Again, this is true for all + or - parabolas.      .......

Store Z

1 - Find out what the price per can is at each store

Store X

4 cans for $2.38

2.38price/4can(s) = price per can

Store x is $0.598/can

Store Y

5 cans for 3.00

$3.00/5

$0.60/can

Comparing these to store Z; store Z is still the better deal.

Answer:

The equation of the line is:

[tex]y=-x+5[/tex]

Step-by-step explanation:

Given the points

Finding the slope between the points

[tex]\left(x_1,\:y_1\right)=\left(-3,\:8\right),\:\left(x_2,\:y_2\right)=\left(4,\:1\right)[/tex]

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{1-8}{4-\left(-3\right)}[/tex]

[tex]m=-1[/tex]

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope

substituting the values m = -1 and the point (-3, 8)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-8=-1\cdot \left(x-\left(-3\right)\right)[/tex]

[tex]y-8=-\left(x+3\right)[/tex]

Add 8 to both sides

[tex]y-8+8=-\left(x+3\right)+8[/tex]

[tex]y=-x+5[/tex]

Therefore, the equation of the line is:

[tex]y=-x+5[/tex]

Answer:

AE:[tex]\sqrt{15300}[/tex]

DE:150

PABCDE: 720

Step-by-step explanation:

We can find AE by the pythagorean theorem, [tex]a^{2}+b^{2}=c^{2}[/tex]

AE is the hypotenuse so AE=c, and the leg of the triangle would be 150-30=120

[tex]50^{2}+120^{2}=c^{2}[/tex]

c^2=2500+14400

AE=130

We can use the pythagorean theorem again to find DE.

The base would equal 140-50=90 and the height would equal 120

[tex]90^{2} +120^{2} =DE^{2}[/tex]

DE^2=22500

DE=150

The perimeter would be 150+140+150+130+150=720
