Answer:
<h2>(f · g)(x) = 4x³ + 4x²</h2>
Step-by-step explanation:
(f · g)(x) = f(x) · g(x)
We have f(x) = 4x² and g(x) = x + 1. Substitute:
(f · g)(x) = (4x²)(x + 1) <em>use the distributive property</em>
(f · g)(x) = (4x²)(x) + (4x²)(1)
(f · g)(x) = 4x³ + 4x²
Answer:
30.7
Step-by-step explanation:
Assuming the angled are degrees and not radian.
side BC= (11÷sin67)•sin28= 5.6
angle ABC= 180-67-28=85°
A= 11•5.6•sin85÷2≈30.68
