A scientist places 7.35 grams of a radioactive element in a dish. The half-life of the element is 2 days. After d days, the number of grams of the element remaining in the dish is
d/2
R(d) = 7.350
given by the function

A
An approximately equivalent equation is R(d) = 7.35(0.250).
B.
An approximately equivalent equation is R(d)= 7.35(0.707).
C.
The base of the exponent in this form of the equation can be interpreted to mean
that the element decays by 0.250 grams per day.
D.
The base of the exponent in this form of the equation can be interpreted to mean
that the element decays by 5.707 grams per day.
E.
The base of the exponent in this form of the equation can be interpreted to mean
that about 25% of the element remains from one day to the next day.
F.
The base of the exponent in this form of the equation can be interpreted to mean
that about 70.7% of the element remains from one day to the next day
