Answer:
Chain referral sampling
Step-by-step explanation:
Chain referral sampling is also known as snowball sampling. In this form of sampling, the samples are collected from the referrals given by the existing samples. The samples are collected and the research is conducted respectively. This method is used in the business marketing also. The places where the people are not known by the company, the method of chain referrals are made and the samples are collected.
D is the correct answer to the equation.
Answer:
y = 2eˣ - sin x + 1
Step-by-step explanation:
dy/dx = 2eˣ - cos x
(0, 3)
Integrate dy/dx to find the original function.
Solve for C by substituting the point given.
- 3 = 2e⁰ - sin(0) + C
- 3 = 2 - 0 + C
- 1 = C
Now we can substitute C into the original function.
This is the particular, or explicit, solution to the differentiable equation.
Answer:
Hence, the particular solution of the differential equation is .
Step-by-step explanation:
This differential equation has separable variable and can be solved by integration. First derivative is now obtained:
, where C is the integration constant.
The integration constant can be found by using the initial condition for the first derivative ():
The first derivative is , and the particular solution is found by integrating one more time and using the initial condition ():
Hence, the particular solution of the differential equation is .
