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>
</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:
Step-by-step explanation:
The solution to this system of linear equations 3x – 2y = 14 and 5x + y = 32 is (x, y) is (6, 2).
Answer:
86,000
Step-by-step explanation:
Find the thousands place value (will be bolded and underlined):
8<u>5</u>,634
Look to the place value directly to the right of what you are looking for. In this case, it is a 6. If the number is 5 or greater round up, if 4 or less, round down:
85,634 rounded to the nearest thousand is 86,000.
