A) is 2x
b) is

c) is -2x
I think these are correct.
![log_{10}1000^{x] = log_{10}10^{2x}=2x](https://tex.z-dn.net/?f=log_%7B10%7D1000%5E%7Bx%5D%20%3D%20log_%7B10%7D10%5E%7B2x%7D%3D2x)

Answer:
D
Step-by-step explanation:
Using the law of sines in ΔABC, then
= 
Substituting in values gives
=
( cross- multiply )
c × sin38° = 25 × sin31.6° ( divide both sides by sin38° )
c =
≈ 21.28 → D
Answer:
x = 437.3 ft
Step-by-step explanation:
Angle of elevation = angle of depression = 29°
Reference angle = 29°
Adjacent side = x
Hypotenuse = 500
Applying trigonometric ratio, we have:
Cos 29 = x/500
Multiply both sides by 500
500*cos 29 = x
437.309854 = x
x = 437.3 ft (nearest tenth)
