Lesson 41 Warm­Up:

1) Find the area of a circle with a diameter of 6m.[Use 3.14 for pi]

2) Find the circumference of a circle with a diameter of 6m. [Use 3.14 for pi]

3) Write 4,137,580,000 in scientific notation.

4) Simplify:(­2) ­ (­6) + (­4)

5) Simplify:(­2)(­6) ­4

Investigation #4:

*geometric solids ­ a 3­D geometric figure

*faces ­ a flat surface of a geometric solid

*edges ­ a line segment formed where 2 faces of a geometric solid intersect

*vertex (vertices) ­ a point where 2 edges of a geometric solid meet

*polyhedron ­ a geometric solid whose faces are polygons

*prism ­ a polyhedron with 2 congruent parallel bases

4

*pyramid ­ a type of polyhedron with lateral surfaces that narrow to a point

*cylinder ­ a geometric solid with 2 parallel bases that are circles

*cone ­ a geometric solid with one circular base that connects to a point

*sphere ­ a smooth curved solid, that has every point the same distance from its center

Lesson 41:

*function – a mathematical rule that identifies a relationship between 2 sets of numbers; for each input there is only one output

*linear function – if all the input­output pairs of a function fall on a line

*For a graph to be proportional, it must be:­linear, ­­pass through (0, 0), ­­­and rises to the right

Examples ­ Lesson 41:For the following functions, make a function table and use the values to graph the equation. Last, determine if the function is proportional or not.A) y = 3x

x y

7

B) y = 2x ­ 1

x y

8

C) y = 1/2x + 1

x y

9

D) y = ­2x

x y

E) Does x = 8 and y = 3 satisfy the function y = 1/4x + 1?
