Consider the differential equation:

y'' + 1 y = f(x)

For each choice of the forcing function f(x), indicate the form of the particular solution, without solving for the constants. Example: f(x) = x2 y(x) = A·x2 + B·x + C

f(x) = xe4 x , y(x) = ?

f(x) = cos 5 x , y(x) = ?

f(x) = x sin 3 x , y(x) = ?

f(x) = sin 1 x , y(x) = ?

f(x) = e1 xcos 1 x , y(x) = ?

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
