5x+4x+3x=180
12x=180
x=30
3(15) = 45 {angle J}
4(15) = 60 {angle H}
5(15) = 75 {angle G}
Double check that the sum of all angles is 180
45+60+75=180
180=180
They are parallel since x and y are bottom and top
Answer: janet will should be her approximately around 5:30
Step-by-step explanation:
Answer:
<u>Mass</u>
<u>Center of mass</u>
<em>Coordinate x</em>
<em>Coordinate y</em>
<em>Coordinate z</em>
Step-by-step explanation:
Let W be the wire. We can consider W=(x(t),y(t),z(t)) as a path given by the parametric functions
x(t) = t
y(t) = 4 cos(t)
z(t) = 4 sin(t)
for 0 ≤ t ≤ 2π
If D(x,y,z) is the density of W at a given point (x,y,z), the mass m would be the curve integral along the path W
The density D(x,y,z) is given by
on the other hand
and we have
The center of mass is the point
where
We have
so
i think you did it. I went through it myself and got from here to there the way ur pencil line in.
