Determine whether each first-order differential equation is separable, linear, both, or neither. 1. ????y????x+????xy=x2y2 2. y+
Mkey [24]

Answer:

a) Linear

b) Linear

c) Linear

d) Neither

See explanation below.

Step-by-step explanation:

a) \frac{dy}{dx} +e^x y = x^2 y^2

For this case the differential equation have the following general form:

y' +p(x) y = q(x) y^n

Where p(x) =e^x and q(x) = x^2 and since n>1 we can see that is a linear differential equation.

b) y + sin x = x^3 y'

We can rewrite the following equation on this way:

y' -\frac{1}{x^3} y= \frac{sin (x)}{x^3}

For this case the differential equation have the following general form:

y' +p(x) y = q(x) y^n

Where p(x) =-\frac{1}{x^3} and q(x) = \frac{sin(x)}{x^3} and since n=0 we can see that is a linear differential equation.

c) ln x -x^2 y =xy'

For this case we can write the differential equation on this way:

y' +xy = \frac{ln(x)}{x}

For this case the differential equation have the following general form:

y' +p(x) y = q(x) y^n

Where p(x) =x and q(x) = \frac{ln(x)}{x} and since n=0 we can see that is a linear differential equation.

d) \frac{dy}{dx} + cos y = tan x

For this case we can't express the differential equation in terms:

y' +p(x) y = q(x) y^n

So the is not linear, and since we can separate the variables in order to integrate is not separable. So then the answer for this one is neither.

This lesson discusses _____ related to the circle.
galina1969 [7]

Answer:

Theorems

Step-by-step explanation:

Theorems is the right answer.

A circle is a geometric figure where all points on the circle keep equal distances from a point called the centre.

A circle has so many important properties.

The important of these are called theorems related to circles.

Some of the theorems are

i)Central angle theorem

ii) Opposite angles are supplementary for a cyclic quadrilateral, etc

Hence theorems would be the appropriate word for filling up the answer

What is the fully factored form of 32a + 12a??
mrs_skeptik [129]

Answer

44a

Step-by-step explanation:

If you factor out 4a you will get 4a(8+3). You then need to add the 8 and the 3 and then multiply it by the 4a and get 44a as your final answer.

Here is a riddle:
lilavasa [31]

Answer:

The system of inequalities that represents this situation will be:

f + s < 10

f - s > 3

Step-by-step explanation:

  • Let 'f' represent the first number
  • Let 's' represent the second number.

Given that the sum of the two numbers is less than 10. As 'less than' can be represented by '<'.

  • so the inequality would be: f + s < 10

Given that If we subtract the second number from the first, the difference is greater than 3. As 'greater than' can be represented by '>'.

  • so the inequality would be: f-s > 3

Thus, the system of inequalities that represents this situation will be:

f + s < 10

f - s > 3
