First: the homogeneous solutions: the characteristic equation is4r^2 - 4r - 3 = 0which has roots r = 3/2, -1/2 hence the homogeneous solution isy = c1.exp(-x/2) + c2.exp(3x/2)
next you need the general form for the guess for yp and that isyp = A1cos(2x) + A2sin(2x)
Now substitute that into the equation and solve for A1, A2.
-14b+28=-10b-30
-4b+28=-30
-4b=-58
b=58/4=29/2
The answer is 21 pounds 7 ounces.
Answer:
x=100°
Step-by-step explanation:
Sum of all angles in a quadrilateral=360
60+x+x+x= 360
60+3x= 360
3x= 360-60
3x=300
x=100
Hope it helps :-)
Answer:
Length = √(y2-y1)² + (x2-x1)²
l = √(5 - 5)² + (9 + 2)²
l = √0² + 11²
l = √121
l = 11
In short, Your Answer would be 11 units
