Answer:
C. All Real Numbers
Step-by-step explanation:
If you take any variable and do the math with that variable on both sides of the equation the answer is always balanced. So, the answer is C.
Answer:
5x+12
Step-by-step explanation:
A number is used as a factor about 5 times
The exponential equation that represents how many grams of the compound will remain after 8 hours is:
B: C=260(0.962)^8
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
A radioactive compound with mass of 260 grams decays at a rate of 3.8% per hour, hence the equation for the mass after t hours is given by:


After 8 hours, the amount is given by:

Hence option B is correct.
