When x is 2, y is 4, p is 0.5, and m is 2. if x varies directly with the product of p and m and inversely with y, which equation models the situation? xpmy = 8 xy/pm = 8 xpm/y = 0.5 x/pmy = 0.5 anyone know the answer to this?

  about 5.6 days

step-by-step explanation:

we can fill the given information into the decay equation and solve for the value of t at which half the sample remains.

the half-life is about 5.6 days.

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.
