Answer:
Range: [-5, 0]
General Formulas and Concepts:
<u>Algebra I</u>
- Range is the set of y-values that are outputted by function f(x)
Step-by-step explanation:
According to the graph, the line's y-values span from -5 to 0. Since both are closed dot, they are inclusive in the range:
[-5, 0] or -5 ≤ y ≤ 0
Answer: 70 meters.
Step-by-step explanation:
Observe the figure attached.
The distance between the walls is:

<em />
Both triangles are right triangles. Therefore, you can calculate the distance between the walls as following:
- Calculate the distance AD:

- Calculate the distance AE:

Therefore the distance between the walls is:

This problem is better understood with a given figure. Assuming
that the flight is in a perfect northwest direction such that the angle is 45°,
therefore I believe I have the correct figure to simulate the situation (see
attached).
Now we are asked to find for the value of the hypotenuse
(flight speed) given the angle and the side opposite to the angle. In this
case, we use the sin function:
sin θ = opposite side / hypotenuse
sin 45 = 68 miles per hr / flight
flight = 68 miles per hr / sin 45
<span>flight = 96.17 miles per hr</span>
