The value of Discriminant is 0.

Step-by-step explanation:

Given,

We need to find the value of discriminant.

And also we need to find the number of real zeros 'f(x)' have.

Solution,

We have given the quadratic equation;

where  

Now we will find the Discriminant.

Discriminant can be calculated by using the formula .

Substituting the values we get;

Hence the value of Discriminant is 0.

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
