The endpoints of this line segment are at (-2, 5) and (2, 3). What is the slope of this line?
| -\(\frac{1}{2}\) | |
| \(\frac{1}{2}\) | |
| 1 | |
| -2 |
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, 5) and (2, 3) so the slope becomes:
m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(3.0) - (5.0)}{(2) - (-2)} \) = \( \frac{-2}{4} \)A quadrilateral is a shape with __________ sides.

A quadrilateral is a shape with four sides. The perimeter of a quadrilateral is the sum of the lengths of its four sides.
A cylinder with a radius (r) and a height (h) has a surface area of:
4π r2 |
|
π r2h |
|
2(π r2) + 2π rh |
|
π r2h2 |
A cylinder is a solid figure with straight parallel sides and a circular or oval cross section with a radius (r) and a height (h). The volume of a cylinder is π r2h and the surface area is 2(π r2) + 2π rh.
If side x = 6cm, side y = 7cm, and side z = 9cm what is the perimeter of this triangle?
| 22cm | |
| 29cm | |
| 28cm | |
| 35cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 6cm + 7cm + 9cm = 22cm
Which of the following statements about a parallelogram is not true?
the area of a parallelogram is base x height |
|
the perimeter of a parallelogram is the sum of the lengths of all sides |
|
a parallelogram is a quadrilateral |
|
opposite sides and adjacent angles are equal |
A parallelogram is a quadrilateral with two sets of parallel sides. Opposite sides (a = c, b = d) and angles (red = red, blue = blue) are equal. The area of a parallelogram is base x height and the perimeter is the sum of the lengths of all sides (a + b + c + d).
