By using the known half-life, we can see that if the initial dose is 500mg, after 4 days the medication will be 0.0076 mg.

<h3>What is the half-life?</h3>

We define half-life as the time such that the initial amount is reduced to its half.

So, if a given substance has a half-life T, then the amount of substance as a function of time, we have:

S(t) = A*e^{-t*ln(2)/T}

Where t is the variable in time units.

We know that T = 6 hours, and A, the initial dose, is 500 mg, so the formula is:

S(t) = 500mg*e^{-t*ln(2)/6h}

Then after 4 days (or 4*24h = 96h) the amount of medication is:

S(96h) =  500mg*e^{-96h*ln(2)/6h} = 0.0076 mg.

If the initial dose was 750mg, after 4 days the person would have:

S(96h) = 750mg*e^{-96h*ln(2)/6h} = 0.0114 mg

So the person would have:

0.0114 mg -  0.0076 mg = 0.038 mg more of medication.

The midpoint QR is M (-1,2). One endpoint is R (3,4). Find the coordinates of the other endpoint.
butalik [34]

M = (x₁ + x₂)/2  , (y₁ + y₂)/2

(-1, 2) = \frac{3 + x}{2} , \frac{4 + x}{2}

At this point, it is easier to separate the x's and y's into two different equations:

x's: -1 = \frac{3 + x}{2}

     -2 = 3 + x

     -5 = x

y's: 2 = \frac{4 + x}{2}

     4 = 4 + x

     0 = x

Answer: (-5, 0)
