Kira wanted to study how the area of a rectangle changes with the length of its width is fixed. She computed the areas of several rectangles that have the same width and different lengths. She then plotted the results and connected them with a line, as shown above. The graph shows the area (in cm ^2) versus the length (in cm). Find the range and the domain of the function shown in the picture above.

Write your answers as inequalities, using x or y as appropriate. Or, you may instead clock on “empty set” or “all reals” as the answer.

A. Range: _

B. Domain: _

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle

The answer would be c

What are the choices
