Answer:
48 (i might be wrong)
Step-by-step explanation:
180-66-66=48
Answer: See explanation
Step-by-step explanation:
You didn't state the sentences but let me help out based on the information given.
Number of new motion toys = 12
Number of batteries used by each toy = 3
Since N represents the total number of batteries he need, the value of N will be:
= Number of toys × Number of batteries used by each toy
= 12 × 3
= 36
That means N equals 36.
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
