Answer:
b) -5^x + 3x - 2
Step-by-step explanation:
(f-g) = -5^x - 4 - (-3x - 2) = -5^x - 4 + 3x + 2 = -5^x +3x - 2
therefore, the answer is b) -5^x + 3x - 2
hope this helps! <3
 
        
             
        
        
        
Answer:
b.  (√15)/4
Step-by-step explanation:
Since Sin Ф = (opposite side)/Hypotenuse, we have 2 sides of a right triangle.  
Use Pythagorean theorem to solve for the missing leg (the adjacent side)
  1² + b² = 4²
     1 + b² = 16
             b² = 15
                  b = √15
So the adjacent side is √15, so Cos Ф = (√15)/4
