To find the half-life of the isotope, we need to determine the value of t when the mass M(t) is equal to half of the original mass. By setting M(t) = 30e^(-0.05t) equal to half the original mass (15 grams) and solving for t, we can find the half-life.
To find the half-life of the isotope, we set the mass M(t) equal to half of the original mass. In this case, the original mass is 30 grams, so we have30e^(-0.05t) = 15Next, we divide both sides of the equation by 30 to isolate the exponential term:e^(-0.05t) = 0.5To eliminate the exponential, we take the natural logarithm (ln) of both sides:ln(e^(-0.05t)) = ln(0.5)Using the property of logarithms, ln(e^(-0.05t)) simplifies to -0.05t:-0.05t = ln(0.5)Finally, we solve for t by dividing both sides of the equation by -0.05:t = ln(0.5) / -0.05Using a calculator, we find t ≈ 13.86 years.Therefore, the half-life of the isotope is approximately 13.86 years.For more such question on isotope

3. Of all the locations in the list below, which has the maximum number of job postings?
L= ["Los Angeles", "New York", "San Francisco", "Washington DC", "Seattle"]
Seattle
Washington DC
Log Angeles
New York
Among the locations in the given list, New York has the maximum number of job postings. So, the correct answer is New York.
To determine the location with the maximum number of job postings, we need to analyze the list provided:
Los Angeles, New York, San Francisco, Washington DC, and Seattle. Based on general knowledge and trends, New York is known for its vibrant job market and diverse industries, making it a likely candidate for having the highest number of job postings among the given locations.
However, without specific data on the actual number of job postings in each location, we cannot provide a definitive answer. Job market dynamics can vary over time, and different industries may have different levels of job opportunities in each city. It's important to note that job availability can be influenced by factors such as economic conditions, industry growth, and local demand.In summary, considering the given list of locations, New York is generally considered a major center for job opportunities and is likely to have the maximum number of job postings. However, without precise data, it is not possible to provide an exact answer. Among the locations in the given list, New York has the maximum number of job postings.

Write é CH general syntax for a polymorphic class
A general syntax for a polymorphic class in C++ would be :
class ClassName : public BaseClassName {
public:
// Member functions and variables
};
How to write the general syntax ?When an object of a derived class is created, it can be used as an object of the base class. This is called polymorphism.
The ClassName class inherits from the BaseClassName class. This means that ClassName objects can be used in any context where a BaseClassName object is expected.
The public keyword specifies that the member functions and variables in the ClassName class are accessible to other classes.
