Ignore above
your equation is 2(cosx)^2-3cosx+1=0
use quadratic formula to get results
you will end up with
cosx=1 or cosx=1/2
so, x=0 or x=pi/3
A) x = -3 x = -1
b) x = 9 x = -5
c) x = -4 x = -2
First, we calculate for the effective interest given the
annual interest and the condition that it is compounded monthly.
<span> Ieff = (1
+ 0.0925/12)^12 – 1 = 0.09652</span>
The equation that would best represent the value of
Grace’s money after x years is equal to,
<span>
An = ($1000)(1.09652)^x</span>
<span>Where x is the number of years</span>
