Answer:
a. 
b. 
c. 
d. 
Step-by-step explanation:
a) xy' -4y = 2 x^6

b) y' - 5y = 4e^7x

c) dy/dx + 2y = 2/(1+e^4x)

d) 1/2 di/dt + i = 4cos(3t)

If you know the slope and a point, the best option is to represent the line in the point-slope form which is:
(y-y1)=m(x-x1), where (x1,y1) is the point and m=slope
To find, the length, divide the area by the width:
Length = 20 / 4 = 5 meters.
5/6 - 1/5 = 19/30 = 0.633
