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.

Answer:
24.75
Step-by-step explanation:
2x-11 + 6x-7 =180
8x-18=180
8x=198 /8
x=24.75

Answer:
53,000x+110,000y < 610,000
Step-by-step explanation:
An inequality refers to the relationship between two values that are not equal. With the information provided, the inequality has to indicate that the salary of the junior programmer multiply for the number of junior programmers plus the salary of the senior programmers multiply for the number of them has to be less than 610,000 as the statement says that the total spending on these new positions must be under $610,000:
53,000x+110,000y < 610,000
