Rose blew h bubbles in two hours. which algebraic expression shows how many bubbles she blew in one minute?

1 answer:

8 0

$\frac{hbubbles}{2hr} = \frac{hbubbles}{120min} \frac{/120}{/120} = \frac{hbubbles/120}{1min}$

She blew h/120 bubbles in 1 minute.

Write down a differential equation of the form dy/dt = ay + b whose solutions have the required behavior as t → ∞. all other sol

nordsb [41]

The ODE has an equilibrium point at

$\dfrac{\mathrm dy}{\mathrm dt}=ay+b=0\implies y=-\dfrac ba$

We want $y=2$ to be an unstable equilibrium solution - in other words, we want all solutions with initial condition $y(t_0)=c$ for $c$ near 2 to diverge from $y=2$ - so $-dfrac ba=2$ .

Divergence from $y=2$ would require that for $y>2$ , any solution is increasing, and for $y$ , and solution is decreasing. In order for that to happen, we need
