Question 3 Unsaved

bazaltina [42]

Answer:

Step-by-step explanation:

DE given is

y''+8y'+15y=0, y(0)=0, y'(0)=1

Take Laplace on the DE

We get

$s^2 Y(s) -sY(0) -y'(0)+8(sY(s)-y(0))+15Y(s) =0\\s^2 Y(s) -s(0) -1+8(sY(s)-0)+15Y(s) =0\\Y(s)(s^2+8s+15)-1=0\\Y(s) = \frac{1}{s^2+8s+15}$

Simplify to get

Y(s) = $\frac{1}{2}[ {\frac{1}{s+3} -\frac{1}{s+5} }]$

Take inverse

$y(t) = \frac{e^{-3t} -e^{-5t}}{2}$

40 points: how do u calculate this and what is sin, cos and what is the formula

dlinn [17]

Answer:

Step-by-step explanation:

sin∅ = opposite side over hypotenuse

cos∅ = adjacent side over hypotenuse

To find <em>x</em>, there are multiple ways:

tan72° = 6/x

x = 6/tan72°

cos72° = x/15

15cos72° = x
