Drag the tiles to the correct boxes to complete the pairs. not all tiles will be used. for each description of a graph, identify the sine function with those parameters. 15) = 4 sin(. – 2) + 8 () = sin(41 + 8) + 2 g() = 2 sin(8.5 + ) + 1 h(s) = 8 sin(n - 2) + 4 p(x) = 8 sin(m + 4) + 2 g) = 4 sin(2x - 7) + 8 amplitude: 2 frequency: 8 midline: y=1 amplitude: 8 frequency: 1 midline: y=4 amplitude: 1 frequency: 4 midline: y = 2 amplitude: 4 frequency: 2 midline: y = 8

Match the following terms with their definitions. 1. bisector of a segment ray ba and ray bc are opposite rays if a, b, and c are collinear and b (the endpoint of both rays) is between a and c. 2. opposite rays a ray, , is the set of points beginning at point a and going infinitely in the direction of point b. 3. collinear points a line or segment that intersects the segment at its midpoint. 4. betweenness of points a set of two or more points all on the same line. 5. ray the distance between the endpoints of a segment. 6. space point b is between a and c if a, b, and c are collinear and the equation ab + bc = ac is true, where ab, bc, and ac are the distances between points a and b, b and c, and a and c, respectively. 7. midpoint of a segment a set of two or more points all on the same plane. 8. coplanar points the point on a segment that divides the segment into two equal segments. 9. length of a segment the set of all possible points. 10. line segment the set of two different endpoints and all points between them.

Elena and her husband marc both drive to work. elena's car has a current mileage (total distance driven) of 15,000 and she drives 23,000 miles more each year. marc's car has a current mileage of 46,000 and he drives 9,000 miles more each year. will the mileages for the two cars ever be equal? explain.

The areas of two similar triangles are 72dm2 and 50dm2. the sum of their perimeters is 226dm. what is the perimeter of each of these triangles?
