The halftime of radio active isotope is the time it takes for a quantity of the isotope to be reduced to half is initial mass starting with 160 g of a radioactive isotope how much will it be left after three half-lives

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

answer: 8 years

step-by-step explanation:

the explanation is that in 8 years the child will be 20 and in 8 years the father will be 40 and 20 is half of 40.

this is impossible to do there is no way you can convert 35/4 into an improper fraction because it already is an improper fraction but you can simplify 35/4 = 8 3/4 or in a decimal 8.75.

hope i ! have a great rest of your week!
