Thepotemich [5.8K]2 years ago
3 0

Answer: the sequence is to divide by 3 and it gets smaller and smaller by dividing by three I don't think there is an end to it.

Step-by-step explanation:

9/3=3

3/3=1

1/3=1/3

1/3/3=1/9

1/9/3=1/27

1/27/3=1/81

and I think you know what I mean by now right?

Which of the following transformations fit the definition of isometry?
Gennadij [26K]

Answer: Rotations, reflections, translations (A, C, and E)

Imagine you had a camera aimed at a triangular figure on a piece of paper. If you rotate the camera, then the image of the triangle appears to rotate. In reality it's the other way around. What this means is that the triangle is not changing at all. It keeps the same size, shape, area, perimeter, etc. This applies to when the camera pans left or right, ie shifts from side to side. The triangle will translate but again the triangle isn't changing at all. It's merely an illusion. Reflections are the same way. Imagine having a piece of glass or a mirror that reflects the image which is an identical copy; although everything is flipped.

Dilations are not isometries because the image is a different size then the pre-image. The same shape is maintained though. Note: the scale factor must be some number other than 1.

another note: "isometry" breaks down into "iso+metry" with "iso" meaning "same" or "equal", and "metry" meaning "measure". So if you had 2 identical yard sticks, then they are isometrical or equal in length.

Nour and Rana are shopping for a Christmas tree. They are deciding between 222 different types of trees (real and fake) and 444
ioda

From what the statement says the question seems to be to represent the sample space of randomly choosing a type of tree and a color for the decorations

In this case, what we must do is identify the events that exist and the options that each event has, like this:

Event 1:

Tree type: real or fake

Event 2:

Colors for the ornaments: White (W), Silver (S), Gold (G) or Purple (P)

Since in an event there are 2 options and the other 4 options, the final number of options would be 2 * 4, that is, 8 options, represented below:

(real, W), (real, S), (real, G), (real, P), (fake, W), (fake, S), (fake, G), (fake, P)

The above would be the sample space of the events.

Now the probability of 1 coming out is 1 over the event total, or 1/8.

16 feet equal how many yards?
elixir [45]

We know that there are 3 feet in one yard. So, to find out how many yards is equivalent to 16 feet, we must divide this number by 3.

16/3 or 5 1/3

Therefore, 16 feet is equal to 16/3 or 5 1/3 yards.

Hope this helps!

Subject differential equation<br>Day. Month.<br>Year. ..<br>(y-secx<br>) dx + tanxdy...o​
Colt1911 [192]

(y-\sec x)\,\mathrm dx+\tan x\,\mathrm dy=0

Divide both side by \mathrm dx and rearrange terms to get a linear ODE;

\tan x\dfrac{\mathrm dy}{\mathrm dx}+y=\sec x

Multiply both sides by \cos x:

\sin x\dfrac{\mathrm dy}{\mathrm dx}+\cos x\,y=1

The left side can be condensed as the derivative of a product:

\dfrac{\mathrm d}{\mathrm dx}(\sin x\,y)=1

Integrate both sides, then solve for y:

\sin x\,y=x+C\implies\boxed{y(x)=x\csc x+C\csc x}

How does the graph of f(x) = (x + 2)4 + 6 compare to the parent function g(x) = x4?
Alchen [17]

Answer: find the answer in the explanation

Step-by-step explanation:

Given that the transformed graph is of function f(x) = (x + 2)^4 + 6 and the parent function g(x) = x^4

The transformed graph function g(x) was shifted two (2) units to the left and was translated six (6) units upward.

When the function is shifted to the right, the factor of x will be negative and when it's shifted to the left, the factor of x will be positive.

Therefore, function g(x) = x^4 is shifted 2 units to the left and translated 6 units upward to form f(x) = ( x + 2 )^4 + 6.
