Sheldon needs to buy 8 gallons of ice cream,

kolbaska11 [484]

Answer:

The larger size container and the Cold farms is the better deal for Sheldon.

Step-by-step explanation:

Given:

1 gallon = 8 pints

$2.50 \times 8 =20$

Multiply the gallons to 20

8 × 20 = 160

Then, the large size is 18.

4.50 ×4 =18 (1 Gallon= 4 quartz)

Therefore, the larger size container and the Cold farms is the better deal for Sheldon.

Solve the initial-value problem y' = x^4 - \frac{1}{x}y, y(1) = 1.

natta225 [31]

The ODE is linear:

$y'=x^4-\dfrac yx$

$y'+\dfrac yx=x^4$

Multiplying both sides by $x$ gives

$xy'+y=x^5$

Notice that the left side can be condensed as the derivative of a product:

$(xy)'=x^5$

Integrating both sides with respect to $x$ yields

$xy=\dfrac{x^6}6+C$

$\implies y(x)=\dfrac{x^5}6+\dfrac Cx$

Since $y(1)=1$ ,

$1=\dfrac16+C\implies C=\dfrac56$

so that

$\boxed{y(x)=\dfrac{x^5}6+\dfrac5{6x}}$
