y = |x|
This is absolute value because it's a v-shape.
The computation shows that the value of the indices will be C. 4.2 × 10^5
<h3>How to calculate the value?</h3>
From the information given, the value will be:
= (7 × 10³) × (5.4 × 10⁴) / (9 × 10)²
It should be noted that in indices when it's multiplication, the powers will be added and subtracted when it's division.
Therefore,
.= (7 × 10³) × (5.4 × 10⁴) / (9 × 10)²
= 4.2 × 10^5
In conclusion, the correct option is C.

Answer:
1731 ft
Step-by-step explanation:
The tangent relation is useful in this problem.
Tan = Opposite/Adjacent
The height of the light is found to be ...
tan(11°) = height/(639 ft)
height = (639 ft)·tan(11°) . . . . . solve for height
Then the distance from the light to point B is ...
tan(3°) = height/(B distance)
B distance = height/tan(3°) = (639 ft)·tan(11°)/tan(3°) ≈ 2370 ft
Then the distance from point A to point B is ...
2370 ft -639 ft = 1731 ft . . . AB distance
