6.35 is the same distance from 6.3 as it is from 6.4
it is exactly between the 2 numbers and 0.05 away from either one
The given graph is parabola graph with vertex at the point (2.0,24) and branches of the parabola go in a negative direction of y-axis.
As known parabola is symmetric about her <span>axis of symmetry and in this case the symmetry axis has equation t=2.0 (vertical line). Thus, the height of the javelin above the ground is symmetric about the line t=2.0.

</span><span>From the graph you can see that the first time when javelin is 20 feet above the ground is when t=1.0 and the second time is t=3.0 (to determine this you should draw horizontal line through point (0,20) and consider two points of intersection (1.0,20), (3.0,20) between parabola and horizontal line).

Answer:
s and t are perpendicular
Step-by-step explanation:
they intersect at a 90 degree angle, which is marked by the little square at the point where they intersect.
Answer:
14.4 to 1 dec. place.
Step-by-step explanation:
By Pythagoras:
17^2 = 9^2 + x^2
x^2 = 17^2 - 9^2
x^2 = 208
x = sqrt 208
x = 14.42.
