Which of the following expressions contains exactly two terms?
monomial |
|
polynomial |
|
binomial |
|
quadratic |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
If side x = 13cm, side y = 11cm, and side z = 10cm what is the perimeter of this triangle?
| 34cm | |
| 31cm | |
| 21cm | |
| 32cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 13cm + 11cm + 10cm = 34cm
If the base of this triangle is 2 and the height is 8, what is the area?
| 72 | |
| 12\(\frac{1}{2}\) | |
| 15 | |
| 8 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 2 x 8 = \( \frac{16}{2} \) = 8
If side a = 5, side b = 2, what is the length of the hypotenuse of this right triangle?
| \( \sqrt{32} \) | |
| \( \sqrt{5} \) | |
| \( \sqrt{29} \) | |
| \( \sqrt{17} \) |
According to the Pythagorean theorem, the hypotenuse squared is equal to the sum of the two perpendicular sides squared:
c2 = a2 + b2
c2 = 52 + 22
c2 = 25 + 4
c2 = 29
c = \( \sqrt{29} \)
On this circle, line segment CD is the:
chord |
|
circumference |
|
radius |
|
diameter |
A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).
