The number of grams of a radioactive isotope present after t years is 1500(12)t. What does 1500 represent in this situation if t>0?

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.

i believe the correct answer is b.

i think is g(1)=-1.

hope that i can
