the answer should be r
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given differential equation is
y"+y'-2y = 1
Hence, the characteristics is
=> D = -2, 1
The general equation of the given differential equation is
Let's consider that
g(t) = 1
Wronskian can be given by,
W = y_1(t)y'_2(t) - y_2(t)y'_1(t)
Now, the particular integral can be given by
Now,
Hence, the complete solution of the given differential equation is
The area of a regular hexagon is the 3 times the product of the apothem and side length.
22. 3*(6.1 m)*(7 m) = 128.1 m^2
23. 3*(11.3 in)*(13 in) = 440.7 in^2
24. 3*(9.5 ft)*(11 ft) = 313.5 ft^2
25. The area ratio is the square of the linear dimension ratio: (3/4)^2 = 9/16.
