Write an equation of the line that passes through (5,9) and is perpendicular to the line y=-1/3x+1

1 answer:

7 0

Perpendicular = opposite sign and reciprocal slope
Slope would be 3
Y = 3x + b, plug in point
9 = 3(5) + b, b = -6
Solution: y = 3x - 6

A cat spends about 7 out of 10 hours sleeping about what percent of a cat's day is spent sleeping

hram777 [196]

I understand that it means that out of every 10 hours, a cat spends 7 sleeping (not 7 hours in a day).

this means that a cat is sleeping $\frac{7}{10}*100%=70%$

a percentage stays constant, this means that a cat sleeps 70 % of each 10 hours, but also 70% of the day.

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
