[10 pts] b) y"+12y'+36 y = 0

yarga [219]

Answer:

The general solution of the differential equation is:

$y=c_1e^{-6t}+c_2te^{-6t}$

Step-by-step explanation:

We have a second order homogeneous differential equation $y''+12y'+36 y = 0$

We need to find the characteristic polynomial

$x^2+12x-36=0$

Next, we find the roots as follows:

$\mathrm{Solve\:by\:factoring}\\\\\mathrm{Rewrite\:}x^2+12x+36\mathrm{\:as\:}x^2+2x\cdot \:6+6^2\\\\\mathrm{Apply\:Perfect\:Square\:Formula}:\quad \left(a+b\right)^2=a^2+2ab+b^2\\\\\left(x+6\right)^2=0\\\\\mathrm{Solve\:}\:x+6=0:\quad x=-6$

The roots of characteristic polynomial are $r=-6$ and $s=-6$

When the roots are real and equal the general solution of the differential equation is:

$y=c_1e^{-6t}+c_2te^{-6t}$

The average wind speed at a local weather station is 34.8 miles per hour. The highest speed ever recorded the stations 318.0 mil

lukranit [14]

Answer:

$Difference = 283.2\ miles/hour$

Step-by-step explanation:

Given

$Average\ Speed = 34.8\ miles/hour$

$Highest\ Speed = 318.0\ miles/hour$

Required

Determine the difference in the highest speed and the average speed

$Difference = Highest\ Speed - Average\ Speed$

$Difference = 318.0\ miles/hour - 34.8\ miles/hour$

$Difference = 283.2\ miles/hour$

<em>Hence, the highest speed is 283.2 miles/hour faster than the average speed</em>
