Answer:

67.5

Step-by-step explanation:

Well area of a triange is 1/2bh so we can find the side closest to us by doing

1/2(3x4) which is 12

the other side would be 1/2 (3x5) which is 7.5

the bottom side would be 1/2(8x4) so 16

and 1/2 (3x8) so 12

1/2 (8x5) so 20

add those together to get 67.5

Hope this helped ya!

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

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