How many quart are 8/1/4 gallons
Westkost [7]

Given:

Consider the given gallons are 8\dfrac{1}{4} gallons.

To find:

The number of quarts in 8\dfrac{1}{4} gallons.

Solution:

We know that,

1 gallons = 4 quarts

Using this conversion, we get

8\dfrac{1}{4}\text{ gallons}=4\times 8\dfrac{1}{4}\text{ quarts}

8\dfrac{1}{4}\text{ gallons}=4\times \dfrac{32+1}{4}\text{ quarts}

8\dfrac{1}{4}\text{ gallons}=4\times \dfrac{33}{4}\text{ quarts}

8\dfrac{1}{4}\text{ gallons}=33\text{ quarts}

Therefore, there are 33 quarts in 8\dfrac{1}{4} gallons.

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)

FromTheMoon [43]

Answer:

y=[-2]x[+][5]

Step-by-step explanation:

\frac{-1-3}{3-1}=\frac{-4}{2} =-2 m= -2

Using the point (1,3) Find the value of b

3= -2(1)+b

3= -2+b

+2  +2

---------

5=b

y= -2x+5
