Which quadratic equation models the situation correctly.

Given a quadratic equation of the form: #ax^2+bx+c = 0# the roots are given by the quadratic formula: #x = (-b+-sqrt(b^2-4ac))/(2a)# Note that if #b# is even, then the radicand #b^2-4ac# is a multiple of #4#, so we end up with a square root that can be simplified. We can incorporate this simplification into a simplified quadratic formula for ...This formula is derived as follows: A = A 0 e k t The continuous growth formula. 0.5 A 0 = A 0 e k ⋅ 5730 Substitute the half-life for t and 0.5 A 0 for f ( t). 0.5 = e 5730 k Divide by A 0 . ln ( 0.5) = 5730 k Take the natural log of both sides. k = …Since D = r · t, D = r · t, we solve for t t and get t = D r. t = D r.

The first general equation of motion developed was Newton's second law of motion. In its most general form it states the rate of change of momentum p = p(t) = mv(t) of an object equals the force F = F(x(t), v(t), t) acting on it, [13] : 1112. The force in the equation is not the force the object exerts.
