Answer:
4
Step-by-step explanation:
Answer:
x^6 + 2 x^5 - 6 x^4 + 3 x^2 + 6 x - 18
Step-by-step explanation:
f(x) = x^2 +2x-6
g(x) =x^4+3
We want to find f*g
(f*g)(x) = (x^2 +2x-6)(x^4+3)
Distribute
=x^2*x^4 +3x^2 +2x*x^4 +2x*3 +-6x^4 -6*3
= x^6 +3x^ +2x^5 +2x^3 -6x^4 -18
Combine like terms
=x^6 + 2 x^5 - 6 x^4 + 3 x^2 + 6 x - 18
Cosine is adjacent over hypotenuse so b/6 since we got those from tangent and sin
The answer is C- 20
a^2 + b^2=c^2
