The answer to the equation is 1.
70 degrees
Angle FED = 180 - 140 = 40
180 (sum of all angles in a triangle) - 40 = 140
140/2 = 70
Answer:
gallons of juice altogether [or, 10 gallons 3 quarts]
Step-by-step explanation:
4 quarts = 1 gallon
So 2 quarts would be 1/2 gallon
Thus,
we have:
4 1/2 gallons in first container
Next container holds 1 3/4 MORE, so that container holds:
gallons
In total, the number of gallons is:
gallons
or 10 gallons and 3 quarts
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.
