11. a ball is thrown upward at a velocity of 15 meters per second from a height that is 20
meters above the ground. the height h (in meters) of the ball at time t in seconds) after it
is thrown can be found by h(t) = -5t^2 + 15t + 20. find the time when the ball is again 20
meters above the ground.
a
1 second
(b
2 seconds
c
3 seconds
d
4 seconds

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.

Iam a rectangle. my perimeter is 60 feet. how much are do i cover?
