The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass
Sauron [17]

Answer:

Quantity remaining= 27.5 grams

Step-by-step explanation:

If the initial quantity of the radioactive isotope= 220 grams

And for each half life it will reduce to half of its original quantity

For first half life

Quantity= 220/2

Quantity= 110 grams

Now for the second half life , the quantity to work with will be 110 grams

Second half life

Quantity= 110/2

Quantity= 55 grams

For the third half life , the quantity to work with is 55 grams

Third half life

Quantity= 55/2

Quantity= 27.5 grams

So after 3 half life's of this radioactive isotope, the amount remaining out of 220 = 27.5 grams.

Another simple way to do this

Since half life reduce the isotope by half of its original.

The third half life will reduce it by (1/2)^3= 1/8

So the quantity remaining= 1/8*220

Quantity remaining= 27.5 grams

Write a quadratic equation in factored form to model the given problem. Be sure to write the entire equation.
Veronika [31]
Equation :
[x(x+4)]/2=6                (as (b*h)/2=A)
x*x + 4*x -12 = 0

x = -b+- \sqrt{ b^{2}-4ac }/2a         

so, x = 2 units(as -6 is negative)
