Answers:
The first five terms are: 3, 8, 13, 18, 23
This is a linear sequence

---------------------------------------------------------------------

Explanation:

Plug in n = 1 to get the first term
E(n) = 5*n-2
E(1) = 5*1-2
E(1) = 3
So 3 is the first term

Do the same for n = 2 to get the second term
E(n) = 5*n-2
E(2) = 5*2-2
E(2) = 8
So 8 is the second term

And again for n = 3
E(n) = 5*n-2
E(3) = 5*3-2
E(3) = 13
This means 13 is the third term

And again for n = 4
E(n) = 5*n-2
E(4) = 5*4-2
E(4) = 18
This means 18 is the fourth term

Finally, repeat for n = 5
E(n) = 5*n-2
E(5) = 5*5 - 2
E(5) = 23
So 23 is the fifth term

This sequence is linear because we're incrementing by the same amount each time. In this case, we're adding 5 each time for the sequence 3, 8, 13, 18, 23, and so on.

Step-by-step explanation:

Thr triangles are similar if any two sides are proportional.

In this, we cannot see any proportional sides, like

DU should be proportional to UT, it is not.

SU should be equal to UE ,it is not.

So, The triangles are not similar.

Hope it helps :)

​ Quadrilateral ABCD ​ is inscribed in this circle.
Sunny_sXe [5.5K]

Answer: m\angle A=116\°

Step-by-step explanation:

The missing figure is attached.

For this exercise it is important to remember that, by definition, the opposite interior angles of an inscribed quadrilateral are supplementary, which means that their sum is 180 degrees.

Based on this, you can identify that the angle D and the angle B are opposite and, therefore, supplementary.

Knowing that, you can write the following equation:

x+28\°=180\°

Now you must solve for "x" in order to find its value. This is:

x=180\°-28\°\\\\x=152\°

Then:

m\angle D=152\°

You know that:

m\angle A=(x-36)\°

Therefore, since you know the value of "x", you can substitute it into   m\angle A=(x-36)\° and then you must evaluate, in order to find the measure of the angle A. This is:

 m\angle A=152\°-36\°\\\\m\angle A=116\°

I really need help if anyone can help that would be great
Oliga [24]
Factor the denominator:

(3x-1)(x+2)

every time x=-2 (because of (x+2), it would cause a warp in the graph, and not have an input. that is the vertical asymptote.

since you have factor 3x-1 on top and bottom, in which the zero is 1/3, there would be no solution at x=1/3. it would be a hole.

the answer here is C.
