Answer:
if give brainliest i will answer
Step-by-step explanation:
 
        
             
        
        
        
Let d represent the distance of the destination from the starting point.
After 45 min, Henry has already driven d-68 miles.  After 71 min., he has already driven d-51.5 miles.
So we have 2 points on a straight line:
(45,d-68) and (71,d-51.5).  Let's find the slope of the line thru these 2 points:
                                 d-51.5 - (d-68)         16.5 miles
slope of line = m = ----------------------- = ------------------
                                     71 - 45                   26 min
Thus, the slope, m, is   m = 0.635 miles/min
The distance to his destination would be d - (0.635 miles/min)(79 min), or 
d - 50.135 miles.  We don't know how far his destination is from his starting point, so represent that by "d."
After 45 minutes:  Henry has d - 68 miles to go;
After 71 minutes, he has        d - 51.5 miles to go; and
After 79 minutes, he has         d -  x miles to go.  We need to find x.
Actually, much of this is unnecessary.  Assuming that Henry's speed is 0.635 miles/ min, and knowing that there are 8 minutes between 71 and 79 minutes, we can figure that the distance traveled during those 8 minutes is
(0.635 miles/min)(8 min) = 5.08 miles.  Subtracting thix from 51.5 miles, we conclude that after 79 minutes, Henry has (51.5-5.08), or 46.42, miles left before he reaches his destination.
        
             
        
        
        
the sequence is in multiples of 4 (2*4=8, 8*4=32, 32*4=128)
so 128*4=512, 512*4=2048, 2048*4=8192 & 8192*4=32768
2+8+32+128+512+2048+8192+32768=43690 
 
        
             
        
        
        
f(x) being even means
f(x) = f(-x)
So the zeros come in positive and negative pairs. If there are an odd number of intercepts like there are here, it's because one of them is x=0 which is its own negation.
Given zero x=6 we know x=-6 is also a zero.
So we know three zeros, and know the other two zeros are a positive and negative pair.
The only choice with (-6,0) and (0,0) is A.

The answer is 1500 I hope this help!
