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
Answer:
(-3+) /2, (3+) / 2 which is approx -3.791 and 0.791
Step-by-step explanation:
i used the quadratic formula: [-b± sq rt (b² - 4ac) / 2a]
in this problem, a = 1, b = 3, and c = -3
The answer is 75 I believe :)
Answer:
3.9
Step-by-step explanation:
i need more detale """))
Given that,
∠C = (6x-21)° and ∠A = (4x+11)°
To find,
Choose the correct option.
Solution,
For a parallelogram, the opposite angles are equal. ATQ,
(6x-21)° = (4x+11)°
Taking like terms together,
6x-4x = 21 + 11
2x = 32
x = 16
∠C = (6x-21)° = 6(16) -21 = 75°
So, ∠A = 75°
So, ∠A = ∠C = 75°. Hence, the correct option is (B).
