yo sup??

as mentioned earlier XUY is simply the summation of all the unique elements of X and Y

S=XUY

={-1,0,1,2,5}

Therefore your answer is option 1 ie

1.{-1,0,1,2,5}

Hope this helps.

Answer:

Step-by-step explanation:

If X = {−1, 0, 2} and Y = {1, 2, 5}

X ∪ Y is the combination of all the element in X and Y without repetition

X U Y = {-1, 0, 1, 2, 5}

Suppose that triangle TUV is an isosceles with the base VU.

vekshin1

Set them equal to each other and solve
3x + 39 = 4x +34
-x=-5
X=5
Plug it in
3(5) + 39 = 54
4(5) +34 = 54
For the final angle ,
54 + 54 = 108
180-108 =72
The angle measures are 54,54, and 72

Find mMK................

Gnesinka [82]

Answer:

Approximately mMK is 53 degrees

Step-by-step explanation:

Here, we want to find the length of MK

As we can see, we have a right triangle at LNK

let us find the angle at L first

9 is adjacent to the angle at L and also, 15 is the hypotenuse of the angle at L

so the trigonometric identity that connects adjacent to the hypotenuse is the cosine

It is the ratio of the adjacent to the hypotenuse

So;

cos L = 9/15

L = arc cos (9/15)

L = 53.13 degree

Approximately, L = 53 degrees

so now, we want to get the arc length MK

We are to use the angle-arc relationship here

Using this; arc length MK is equal to the measure of L at the center which is 53 degrees

The graph represents function 1, and the equation represents funtion 2:

horsena [70]

Answer:

Step-by-step explanation:

we know that

The rate of change of a linear equation is a constant that is the same that the slope

step 1

we have

The equation of the graph (function 1) is equal to

y=4

Is a horizontal line

The slope is equal to zero

The rate of change of function 1 is zero

step 2

The equation of the function 2 is

$y=8x+12$

This is a linear equation in slope intercept form

where

the slope is equal to m=8

The rate of change of function 2 is 8

therefore

The rate of change of function 2 is 8 more than the rate of change of function 1
