When adding fractions, you have to make sure the bottom numbers are the same. Otherwise, you can't add them.

So currently, the bottom number for the first fraction is 5. The bottom number for the second fraction is 2.

As you can see, 5 is not the same as 2, so we need to find one number to make sure the bottom number is the same for both the fractions.

You can multiply the the first fraction by 2, and the second fraction by 5 to give you two fractions that have the same denominator (bottom number.)

So, 3/5 multiplied by 2 is the same as multiplying 3 by 2, and 5 by 2. That gives you 6/10.

1/2 multiplied by 5 is 1 multiplied by 5, and 2 multiplied by 5, which is 5/10.

Now that you have your converted fractions, you can add them and forget about the bottom number, as it's the same. When adding fractions, if the bottom numbers are equal, you leave it as it is, so the 10 stays as 10:

6/10 + 5/10 = 11/10 

Notice how I added 6 and 5 to give me 11, but I don't add 10 + 10, because I don't need to.

So the answer is 11/10.

Solve the given differential equation by undetermined coefficients. y'' 4y = 7 sin(2x)
kherson [118]

The solution to the given differential equation is yp=−14xcos(2x)

The characteristic equation for this differential equation is:

P(s)=s2+4

The roots of the characteristic equation are:

s=±2i

Therefore, the homogeneous solution is:

yh=c1sin(2x)+c2cos(2x)

Notice that the forcing function has the same angular frequency as the homogeneous solution. In this case, we have resonance. The particular solution will have the form:

yp=Axsin(2x)+Bxcos(2x)

If you take the second derivative of the equation above for  yp , and then substitute that result,  y′′p , along with equation for  yp  above, into the left-hand side of the original differential equation, and then simultaneously solve for the values of A and B that make the left-hand side of the differential equation equal to the forcing function on the right-hand side,  sin(2x) , you will find:

A=0

B=−14

Therefore,

yp=−14xcos(2x)

Find the slope of the line passing through the points (-5, 3) and (7,9).
dybincka [34]

Answer:

\huge\boxed{slope=\dfrac{1}{2}=0.5}

Step-by-step explanation:

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points

(-5;\ 3)\to x_1=-5;\ y_1=3\\(7;\ 9)\to x_2=7;\ y_2=9

Substitute:

m=\dfrac{9-3}{7-(-5)}=\dfrac{6}{7+5}=\dfrac{6}{12}=\dfrac{6:6}{12:6}=\dfrac{1}{2}
