2 cm = 5 feet
1 cm = 2.5 feet
9 cm = 9 * 2.5 = 22.5 feet by
4 cm = 4 * 2.5 = 10.0 feet
The distance between the helicopter and the first home is 369. 87 m
<h3>How to solve the distance using the angle of depression?</h3>
The distance between the helicopter and the first home can be found using sine law,
Hence,
180 - 72 - 49 = 59 degrees.
Therefore,
420 / sin 59 = A / sin 49°
where
- A = distance form the first home to the helicopter.
cross multiply
420 sin 49 = A sin 59°
A = 420 sin 49 / sin 59
A = 316.978023694 / 0.8571673007
A = 369.869339199
A = 369. 87 m
Therefore, the distance between the helicopter and the first home is 369. 87 m

Answer:
Step-by-step explanation:
From the graph <em>f</em>(-2) = 0
g(-2) = -3(-2) + 2
= 6 + 2 = 8.
So f(-2) is less than g(-2).
2. From the graph the y-intercept of f(x) = 8.
To find the y-intercept of g(x) solve y = -3x +2 when x = 0:
y = -3(0) + 2 = 2.
So f(x) has a greater y-intercept than g().
