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

Simplify to get
Y(s) = ![\frac{1}{2}[ {\frac{1}{s+3} -\frac{1}{s+5} }]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5B%20%7B%5Cfrac%7B1%7D%7Bs%2B3%7D%20-%5Cfrac%7B1%7D%7Bs%2B5%7D%20%7D%5D)
Take inverse

Answer:
2x+8y=6
Step 1: Add -8y to both sides.
2x+8y+−8y=6+−8y
2x=−8y+6
Step 2: Divide both sides by 2
= 
x=−4y+3

Answer:
3/20
Step-by-step explanation:
0.15 = 15*100/1*100
= 15/100
= 3/20
Answer: B. Exponential. There is a constant rate of decay or decrease.
The y-values decrease by 1/4 of the number that comes before every time.
Answer:
The circle graph does not represent a function because it doesn't pass the vertical line test.
