Answer:
Step-by-step explanation:
As given in question, we have to find the solution of differential equation
by using the variation in parameter method.
From the above equation, the characteristics equation can be given by
Since, the roots of characteristics equation are real and distinct, so the complementary function of the differential equation can be by
Let's assume that
and g(t)=1
Now, the Wronskian can be given by
Now, the particular solution can be given by
Now, the complete solution of the given differential equation can be given by
Answer:
D) 1980 to 2000
Step-by-step explanation:
Finding the average rate of change in each interval to determine the greatest one.
Production per interval
1950-1960 = = 10 million
1960-1970 = = 20 million
1970-1980 = = 30 million
1980-2000 = million
Rate of change (1950-1960)=
Rate of change (1960-1970) =
Rate of change (1970-1980)=
Rate of change (1980-2000)=
∴ rate of change between 1980 to 2000 is 126.78%
Answer:
19
Step-by-step explanation:
8 x 4 = 32
32 + 6 = 38
38 / 2 = 19
