Answer:
p = 5 and q = -3
Step-by-step explanation:
nth term = pn^2 + qn where n is the sequence number.
first term = p + q = 2.....................(1)
2nd term = p(2)^2 + 2n = 14
4p + 2q = 14
2p + q = 7 .......................(2)
Subtract equations (2) -(1) :-
p = 7 - 2 = 5
and q = 2 - 5 = -3

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
The order from least to greatest is 0<u>.8%, 0.556, 1.2 and 10/8</u>
<h3>Ordering of numbers</h3>
In order to order the given numbers, we will first have to write them as a percentage as shown.
Given the number below
10/8, 1.2, 0.556, 0.8%
Convert to percentage
10/8 = 125%
1.2 = 120%
0.556 = 55.6%
0.8%
Hence the order from least to greatest is 0<u>.8%, 0.556, 1.2 and 10/8</u>
