The amount of a radioactive isotope decays in half every year. the amount of the isotope can be modeled by f(x) = 346(one half)x and f(1) = 173. what does the one half represent? a)the starting amount of the isotope b) the amount of the isotope after one year c) the rate the isotope decreases d) the number of years that have passed

Exponential decay formula is :

Where a≠0, b≠1 , b represent growth or decay factor (or rate) and x is any real number.

But if a radioactive isotope decays in half every year which means the decay factor or decay rate is 50% or .

So, the formula for half decay will be:

Where represent c) The rate of isotope decreases.

students group

step-by-step explanation:

a person who   joins a party or a seminar can explain his feelings about that particular occasion better more than anyone else.

as bella managed a show for the students in the school and invited students to watch that show

hence

students group will be the best group to survey to find this information
