If side a = 5, side b = 3, what is the length of the hypotenuse of this right triangle?
| \( \sqrt{26} \) | |
| \( \sqrt{10} \) | |
| \( \sqrt{34} \) | |
| \( \sqrt{74} \) |
According to the Pythagorean theorem, the hypotenuse squared is equal to the sum of the two perpendicular sides squared:
c2 = a2 + b2
c2 = 52 + 32
c2 = 25 + 9
c2 = 34
c = \( \sqrt{34} \)
Order the following types of angle from least number of degrees to most number of degrees.
right, acute, obtuse |

acute, obtuse, right |
An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
The endpoints of this line segment are at (-2, 0) and (2, 2). What is the slope of this line?
| 3 | |
| -2 | |
| \(\frac{1}{2}\) | |
| -3 |
The slope of this line is the change in y divided by the change in x. The endpoints of this line segment are at (-2, 0) and (2, 2) so the slope becomes:
m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(2.0) - (0.0)}{(2) - (-2)} \) = \( \frac{2}{4} \)The dimensions of this cylinder are height (h) = 1 and radius (r) = 4. What is the volume?
| 1π | |
| 128π | |
| 6π | |
| 16π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(42 x 1)
v = 16π
