Answer:
3, 5
Step-by-step explanation:
Looking at the graph, the x-intercepts are -5, -3, 1 and 5.
Hence the graph equation is (x+5)(x+3)(x-1)(x-5)

Part 1:
we must see in the graph the axis of symmetry of the given parabola.
The axis of symmetry is the following vertical line:
Answer:
The height of the javelin above the ground is symmetric about the line t = 2 seconds:
Part 2:
we must see the time t for which the javelin reaches a height of 20 feet for the first time.
We have that when evaluating t = 1, the function is:

To do this, just look at the graph.
Then, we must observe the moment when it returns to be 20 feet above the ground.
For this, we have from the graph that:

Therefore, a height of 20 feet is again reached in 3 seconds.
Answer:
The javelin is 20 feet above the ground for the first time at t = 1 second and again at t = 3 seconds
Tea : 2 pints lemonade : 2 pints / Tea : 1 pint Lemonade : 3 pints
3 Eggs: 4 times what equals 12? (We use 4 because its 1/4 or a quarter) 3 times 4 equals 12.

Hope this helped :)
Step-by-step explanation:
Watson's $130 - 50% = $65
Hartman's $130 - 40% = $78
$78 - 15% = About $66
