Carly is playing her violin at a music festival and earns $8 for each song she plays. Maxwell is playing at a local coffee shop
sveta [45]

Answer:

If you wanted to know how much songs Maxwell will have to play to pay the fee to play there, ($50 dollars)  he will have to play 5 songs.

Step-by-step explanation:

The question to the awnser is how much can 10 go into 50. That means you have to divide 50 by 10. You can put 10 5 times into 50, and you can make sure of that by timing 10 by 5. I have no idea though what you need. Sorry if im saying somthing different than wht you want.

Consider the first order differential equation
AURORKA [14]

Answer:

For y(-7) =6.4

        The  largest interval  is  between  

                                       -\infty \to -5

For   y(-2.5) = -0.5.

          The  largest interval  is  between  

                                        -5 \to 5

For  y(0) = 0

          The  largest interval  is  between  

                                        -5 \to 5

For y(4.5) = -2.1.

            The  largest interval  is  between  

                                        -5 \to 5

For y(14)= 1.7.

                          The  largest interval  is  between  

                                        9 \to \infty        

   

Step-by-step explanation:

From m the question we are told that

     The first order differential equation is   \frac{y' -  t}{ t^2 -25} =  \frac{e^t}{t-9}

Now the first step is to obtain the domain of the differential equation

Now to do that let consider the denominators

  Now generally

                           t^2 - 25 \ne  0                                           side calculation

                   =>     t\ne \pm5                                                      t^2 - 25 =  0

                                                                                          t = \pm 5

Also              t-9\ne 0                                                     t -9 = 0

        =>          t\ne 9                                                            t= 9    

This means that this  first order differential equation is discontinuous at

       t =  -5 ,  \   \  t =  5 \ \  t =  9

  This  \  is \  illustrated \  below    \  \\      ------------------\\\. \ \ \  | \ \ \   \ \ \   \ \ \ \  \ \ \ \ \ | \ \ \ \ \ \ \ \ \ \ \ \ \ |\\. \  -5 \ \ \ \ \  \ \ \ \ \ \ \  5 \ \ \ \ \ \ \ \ \ \ \ \ \   9

So

For y(-7) =6.4

        The  largest interval  is  between  

                                       -\infty \to -5

For   y(-2.5) = -0.5.

          The  largest interval  is  between  

                                        -5 \to 5

For  y(0) = 0

          The  largest interval  is  between  

                                        -5 \to 5

For y(4.5) = -2.1.

            The  largest interval  is  between  

                                        -5 \to 5

For y(14)= 1.7.

                          The  largest interval  is  between  

                                        9 \to \infty
