The amount, a, in milligrams, of radioactive material remaining in a container can be modeled by the exponential function a(t)=5(0.5)^0.25t where t is time, in years. based on this model how many years does it take for half of the original radioactive material to be left remaining?

4 years

Step-by-step explanation:

The exponent of 0.5 is 1 when t=4. So, half the original amount will be remaining when t=4.

rick would give her the best deal as he will charge $8.88 per hour

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
