Right back at ya'......

(17 / 20)  x 40%  

Note that there are 20 parts to the 40%....so.....each part is 2%   ....and you have 17 of them....so....

17 x 2%  =   34%

346 / (1 /2)  =

346 x 2  =  692

There are infinite possibilities....

To see why....look at the following graph.....where x = L and y = W   and both are positive  (i.e., in the first quadrant of the xy grid ).....

Oh, OK....this is a litttle different....

2^(4x-1)=7       take the log of each side

log 2 ^(4x - 1)   = log 7     and we can write

(4x - 1) log 2  = log 7        divide both sides by log 2

4x - 1   =  log 7 / log 2      add 1 to both sides

4x   =  (log 7 / log 2 ) + 1      divide both sides by 4

x = [( log 7 / log 2 )  +  1 ]  / 4   = about  .9518

2^4x-1=7   add 1 to both sides

2^4x  = 8        and we can write 8  as 2^3  ....so we have...

2^4x  = 2^3      and, because the bases are the same,  we can equate exponents

4x  = 3       divide by 4 on both sides

x = 3/4 

Given a line segment, a perpendicular bisector is a line (or segment) that intersects the given segment at  right angles to the segment's midpoint.

Here's a pic....

AB  is the given segment.....and CD is the perpendicular bisector

The interest is given by :

57700(1 + .071 / 12)^{(2 x 12)}  -  57700   = about    $ 8775.85

The radius of the clock is 3  = r

And the angle betwen the hands  = 120°  = (2/3)pi rads

And the arc length formula is given by :

s  = rΘ     where s is the arc length and Θ  is in rads

So we have....

s = 3 (2/3)pi = 2 pi  = 6.28 in
