ANSWER
Option D is correct
EXPLANATION
We resolve the forces into component forms.
Also the second is resolved to obtain,
To find the resultant vector, V, We add the corresponding components of the two forces to get:
The correct answer is D.
F(x)=x^2 what is g(x)?

Answer:
B
Step-by-step explanation:
You are given that a valid point on g(x) is (4,1) or y=1 when x=4
Substitute this point into each of the choices and see which one is valid.
A : g(x) = x² = (1/4) (4²) = 4 ≠ 1 (not valid)
B: g(x) = [(1/4) x]² = [(1/4) 4]² = 1² = 1 (valid)
C: g(x) = 4x² = 4 (4²) = 64 ≠ 1 (not valid)
D: if you expand it out, you'll find that this is identical to option A which we determined earlier to be not valid.
Hence the only valid choice is B

Answer:
x ≈ 15.9
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + 6² = 17²
x² + 36 = 289 ( subtract 36 from both sides )
x² = 253 ( take the square root of both sides )
x = ≈ 15.9 ( to the nearest tenth )
