<span>arccos (cos pi/2)=?
</span>cos pi/2=0, arccos (0)=?, we know that cos pi/2=0, so cos^-1 (o)= Pi/2, but cos^-1 (o)=arccos (0), so arccos (cos pi/2)=Pi/2
I = PRT
720 = (1,000)(0.09)(t)
720 = 90(t)
720/90 = t
8 = t or t = 8
I am not sure if it is terms of months or years but 8 is the answer. hope it helps :)
