Answer:
14 square meters
Step-by-step explanation:
The formula for the area of a parallelogram of length L and height H is
A = L * H.
Here, the area is A = (2 meters) * (7 meters) = 14 square meters.
This answer hinged upon my understanding of this situation, and could be incorrect because I'm not taking into account the "triangle" mentioned here. When at all possible you should share any diagrams given in the problem statement, or at least describe them accurately in words.
The y-intercept (initial value) is 10 and it has a slope of -1, so this is the first graph.

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
Answer:
c
Step-by-step explanation:
its a, b, and d because these have inputs with different outputs
ex. (-3,-5) and (-3,3)
