Vector u has a magnitude of 7 units and a direction angle of 330°. Vector v has magnitude of 8 units and a direction angle of 30
°. What is the direction angle of their vector sum?
1 answer:
Keeping in mind that x = rcos(θ) and y = rsin(θ).
we know the magnitude "r" of U and V, as well as their angle θ, so let's get them in standard position form.

g(x)=3*2
=6
f(x)=(4x+3)2
=8x+6
g(f(-4))
f(x)=8x+6
f(-4)=8(-4)+6
=-32+6
= -26
g(f(-4))=6(-26)
=-156
