Check all options:

A. The notion \overleftrightarrow{YX} represents the line YX. As you can see the line YX is present in the diagram.

B. Start with point Z, go to the point X and then to the point Y. You path is along ∠ZXY sides, this means that you can see ∠ZXY on the picture.

C. The notion \overrightarrow{ZX} represents the ray ZX. On the picture is given segment ZX, not ray, then this option is false.

D. To form the ∠XYZ you have to connect points Z and Y. Without this connection ∠XYZ cannot be seen. This option is false.

Answer: True options are A and B.

Answer:

Option A & B are true and on diagram.

Step-by-step explanation:

Option A: The given notation in this option representing A line XY. Clearly a stright line is seen in diagram having vertex X & Y.

Thus, this appears in Diagram.

Option B: ∠ZXY represnts an Angle whose vertex is X and Two arms are XZ & XY. This means that it is present in Diagram.

Thus, This appears in Diagram.

Option C: The given notation represents the Ray ZX whose initial point/start point is Z and it can be extended in X direction. There no such ray on the diagram.

Thus, This option is not on diagram.

Option D: ∠XYZ represnts an Angle whose vertex is Y and Two arms are XY & YZ. But there is no YZ line in the diagram.

Therefore this option is not on diagram.

Answer: True options are A and B.

Find the diagonal of a television screen 30 inches wide by 35 inches tall.
marin [14]

Answer:

46.1 in

Step-by-step explanation:

Given data

Width= 30in

Height= 35in

To find the diagonal, we have to use the Pythagoras theorem

z^2= x^2+y^2

z^2= 30^2+ 35^2

z^2= 900+1225

z^2= 2125

z= √2125

z= 46.09

Hence the diagonal of the TV is 46.1 in

What is the length of AA' , rounded to the nearest hundredth? Type a numerical answer is the space provided. Do not type spaces
inna [77]
Coordinate of A are (0,0)
Coordinates of A' are (5,2)

We can find the distance from A to A' using the distance formula:

AA'= \sqrt{(5-0)^{2}+ (2-0)^{2}  } \\  \\ 
AA'= \sqrt{25+4} \\  \\ 
AA'= \sqrt{29} \\  \\ 
AA'=5.39

Thus, rounded to nearest hundredth, AA' is equal to 5.39

Solve the inequality –3(r – 5) + 7 > 28.
docker41 [41]

Answer: r<-2

Step-by-step explanation:

-3(r-5)+7>28

-3(r-5)+7-7>28-7

-3(r-5)>21

3(r-5)/3 < -21/3

r-5<-7

r-5+5<-7+5

r<-2

7 x 5e = 105 <br><br><br>plz help ​
Anon25 [30]

e=3.

So this is how I approached this. Since 7 is being multiplied, I divided both sides by 7 so 105/7 = 15. Then it becomes simple as 5e=15. We divide both sides by 5 and get e=3. Tip: just try isolating the variable and then life is much easier.
