Answer:
The general solution is

+ 
Step-by-step explanation:
Step :1:-
Given differential equation y(4) − 2y''' + y'' = e^x + 1
The differential operator form of the given differential equation
comparing f(D)y = e^ x+1
The auxiliary equation (A.E) f(m) = 0




The roots are m=0,0 and m =1,1
complementary function is 
<u>Step 2</u>:-
The particular equation is 
P.I = 
P.I = 
P.I = 



applying in integration u v formula

= 





again integration 
The general solution is 

+ 
Answer:
4.63
Step-by-step explanation:
4/5 of an hour is 48 minutes
1 4/5 hour is 60 + 48
which is
108 minutes
he ran 8 1/3 miles in 108 minutes
so
(8 1/3 times 60 ) ÷ 108
which =
4.6296296296 miles in one hour
I’m on the way home I can see if I could have a good time at your house and I’ll
Angle TVU = 1/2 (120 - 12) = 108/2 = 56°
Therefore, the correct answer is D.
