Answer:
3n - 6 = 38
3n -6 + 6 = 38 + 6
3n = 44
3n/3 = 44/3
n = 44/3
Step-by-step explanation:
1. set up the equation (the - affect the 6 not the 3)
2. add 6 to both sides
3. divide both sides by 3 to get n
Answer: 4.5 metres
Step-by-step explanation:
Using Hooke's Law ()
We need to find the spring constant of the bungee cord with the given extension and force, we can do this by substituting in known values.
Now we have found the spring constant of the bungee cord, we can substitute it in for the a different force. As the cord is the same we can use the same spring constant.
We need to find the height of the cylinder
pythagorean theorem
15 is the bottom leg (30/2=15)
17 is hypotonuse
b=height
15^2+b^2=17^2
225+b^2=289
minus 225 both sides
b^2=64
sqrt both sides b=8
Vcone=(1/3)hpir^2
d/2=r=30/2=15
h=8
V=(1/3)8pi15^2
V=(1/3)8pi225
V=8pi75
V=600pi
aprox pi=3.14159256
V=1884.955536 in^3
round if nececary
