Can you form a right triangle with the three lengths given? Why or why not? 5 cm, 12 cm, 13 cm
nordsb [41]

Yes,  I  form a right triangle with the three lengths given, because The largest side which is 13cm can be squared  and will be set to  equal to the sum of squares of smaller two side.

<h3>What is a right-angled triangle?</h3>

A  right-angled triangle serves as the  triangle having  one of its angles equal to 90 degrees.

It should be noted that the other two angles sum up to 90 degrees., hence  I  form a right triangle with the three lengths given, because The largest side which is 13cm can be squared  and will be set to  equal to the sum of squares of smaller two side.

Please Help me. Also if you could show your work thatd be great.
Over [174]

Answer:

3) all \: real \: numbers, (  - \infty , \infty ), or -  \infty  \leqslant x \leqslant  \infty (same thing)

4) -  \infty  < y < 0 or ( -  \infty ,0) (same thing)

5) -2 or (0, -2) (same thing)

Step-by-step explanation:

3) Domain represents the amount of x-values in a function. The image shows that the function's arrows point in both directions (right and left), infinitely, so the domain would be all \: real \: numbers, (  - \infty , \infty ), or -  \infty  \leqslant x \leqslant  \infty(same thing).

4) Range represents the amount of y-values in a function. The function goes downward forever (- \infty  < y) by the indication of an arrow and halts just under the y-axis (y < 0). After combining these two inequalities, you see that the range is -  \infty  < y < 0 or ( -  \infty ,0) (same thing).

5) The y-intercept is where the function crosses the y-axis. In this function, the y-intercept is -2 or (0, -2) (same thing).

Find the value of x.<br><br> RZ = 30<br> SW = 5x - 20
Murrr4er [49]
|RZ|=0.5|SW| therefore 2|RZ|=|SW|.

5x - 20 = 2 · 30

5x - 20 = 60    |add 20 to both sides

5x = 80    |divide both sides by 5

x = 16

Anthony travels from Page Az to Flagstaff Az at a rate of 60 miles per hour in 2.5 hours. How far is Flagstaff from Page?( Show
DerKrebs [107]

Answer:

150 miles

Step-by-step explanation: The distance from Page to Flagstaff can be shown with the equation d = r * t, or distance = rate * time. In this case, the rate is 60 mph, and the rate is 2.5 h. Plugging that into the equation you get d = 2.5(60) = 150, giving you your distance.
