D. y = Ae^5x^2
E. y = A cos(5x) + B sin(5x)

Step-by-step explanation:

1.    

    The characteristic equation for the given differential equation is:

   Since the roots are complex

Now, the general solution is:

2.    

  Divide both sides by

  Let,

 Here,

 I.F.

 Now, the general solution is:

3.    

   The characteristic equation is:

 Since the roots are real and repeated.

 Now, the general solution is:

4.    

 Integrating both sides

5.      

      Here,

  I.F.

  Now, the general solution is:

               Let,

$35.59 in pounds

step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
