Solve the equation. dx/dt =3/xet +9x An implicit solution in the form F(t. x)C, where C is an arbitrary constant.

Step-by-step explanation:

It is given that there is arbitrary constant C and we have to find the implicit solution. Therefore, first separate the variable that is given in equation and then use integration to find the implicit solution. Here, below is the calculation.

 The given equation is:

Now, if we use separation of variable.

Now integrate both side:

Thus, the implicit solution is:

answer: 177/8

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
