Answer:
this isn’t a 100% guaranteed correct answer but maybe the second option saying “PQ and P’G’ are parallel”
(i’m doing the test rn)
 
        
                    
             
        
        
        
Answer is TanJ=8/15 if that’s what your asking
        
                    
             
        
        
        
Find 20% first
20% of 84 is 16.8
tax is 7% of 84 which is 5.88
total
84+16.8+5.88=$106.68
        
             
        
        
        
        
a) Acceleration is the derivative of velocity. By the fundamental theorem of calculus,

so that


b) We get the displacement by integrating the velocity function like above. Assume the object starts at the origin, so that its initial position is  . Then its displacement over the time interval [0, 3] is
. Then its displacement over the time interval [0, 3] is

c) The total distance traveled is the integral of the absolute value of the velocity function:

 for
 for  and
 and  for
 for  , so we split the integral into two as
, so we split the integral into two as
