Situation: an archaelogist in turkey discovers a spear head that contains 54% of its original amount of c-14. n = noekt no = inital amount of c-14 (at time t = 0) n = amount of c-14 at time t k = 0.0001 t = time, in years find the age of the spear head to the nearest year

Which is the standard form of the equation of the parabola that has a vertex of (-4,-3) and a directrix of x = 2? (x+3)2 = 24(y+4) (y+3)² = 24(x-4) (y+3)² = -24(x+4) (x+3)2 = -24(y+4)
