Answer:
   m∠V ≈ 61°
Step-by-step explanation:
The hypotenuse and the side opposite the angle of interest are given. The relevant trig relation is ...
   Sin = Opposite/Hypotenuse
   sin(V) = XW/XV = 7/8
The inverse sine function is used to find the angle:
   V = arcsin(7/8) ≈ 61°
 
        
             
        
        
        
Answer:
   B) x = e^x
Step-by-step explanation:
The graphs of y = e^x and y = x never intersect, so the solution set will be the empty (null) set for ...
   x = e^x
_____
There is one intersection of y=x with cos(x) and with sin(x). There are an infinite number of solutions for x = tan(x).

Answer:
490
Step-by-step explanation:
546-56= 490
490+56= 546
 
        
                    
             
        
        
        
Answer:
26 2/3 minutes:  The two boys meet after 26 2/3 minutes
Step-by-step explanation:
Distance covered by Jim = Distance covered by Bob
      (5 mph)(t)                      = (8 mph)(t - 10)
Simplify this by performing the indicated multiplication:
            (5 mph)(t)                 = (8 mph)(t) - 80 mi
or:
                  80 mi                 = (3 mph)(t), or
      80 mi
t = ----------- = 26 2/3 minutes
      3 mph
