Okay, so I've tried working this out but I keep coming across different formulas and it's getting really aggravating. I would really appreciate the help!

$56,500 at 11.5% compounded semiannually for 7 years. How much interest was earned each year?

This is the last time I've tried to solve it, so am I even close to the answer or what am I doing wrong??

Formula: A=P(1+r/n)^nt x 2

A = 56,500(1+0.115/2)^(7 x 2)
= 56,500(1.0575)^(7 x 2)
= 56,500(2.18739)
=12,3587.54

question is incomplete.

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
