Find the solution of the differential equation that satisfies the given initial condition.

andriy [413]

$\displaystyle \frac{dy}{dx} = \frac{x}{y} \ \Rightarrow\ y \,dy = x\, dx\ \Rightarrow\textstyle \ \int y \,dy = \int x\, dx\ \Rightarrow\ \frac{1}{2}y^2 = \frac{1}{2}x^2 + C \Rightarrow \\ \\
y(0) = -3\ \Rightarrow\ \frac{1}{2}(-3)^2 = \frac{1}{2}(0)^2 + C\ \Rightarrow\ C = \frac{9}{2},\\ \\
 \text{so } \frac{1}{2}y^2 = \frac{1}{2}x^2 + \frac{9}{2}\ \Rightarrow\ y^2 = x^2 + 9 \ \Rightarrow \ \\ \\
y = -\sqrt{x^2 + 9}\ \text{ since $y(0) = -3 \ \textless \ 0$}$

Please explain how to do this

Answer:

A = 5t +7000

Step-by-step explanation:

Tim's rate of increasing altitude is 5 ft/min, so his change in altitude in t minutes is 5t.

If he started at 7000 ft, his altitude as a function of time is the sum of his initial altitude and his change in altitude:

A = 5t +7000
