Answer:
35.7 km and 248.3 °
Step-by-step explanation:
To clarify, I will include a diagram as an image.
We begin with the cosine law formula:
y² = 42² + 28² - (2 * 42 * 25 * cos 58 °)
y² = 2389 - 1112.83 = 1276.17
y = √1276.17
y = 35.72 km
Next, to find the bearing of the surveyor from her camp, we apply the sine law:
[(Sin 58 °) / y] = [(Sin A) / 42]
Here, A = (42 * sin 58 °) / 35.72
A = sin⁻¹ (0.9971)
A = 85.7 °
The bearing from the base camp now calculates to: 270 ° - (85.7 ° - 64 °) = 248.3 °
Answer:
- No, the second machine (function B) can produce an output of 0, while the first machine (function A) cannot.
Explanation
The functionality of each machine is dictated by the expression it operates under.
1) Function A:
To achieve an output of 0 with the equation y = x² + 3, one would need to resolve the equation x² + 3 = 0.
Given that x² is always non-negative for any real number, x² + 3 will always be at least 3, meaning an output of 0 is unattainable with the first machine.
2) Function B:
By solving
Thus, utilizing x = 4 will yield an output of 0 with this machine.
