Answer: 384 feet
Step-by-step explanation:
      We will simplify and solve -16t² + 160t when t is equal to 4.
-16t² + 160t
-16(4)² + 160(4)
384 feet
 
        
                    
             
        
        
        
Answer: Value of m = 9
Step-by-step explanation:
Given that the relationship between Q and m is;
Q = 17m
Make m the subject of formula 
M = Q/17
If Q is greater than 150 and less than 160, then, let assume that 
Q = 151, then
M = 151/17
M = 8.88
If Q = 159
M = 159/17
M= 9.35
Since m ranges from 8.88 to 9.35, the value of m = 9
