Solution:
Given, x=-3, y=6, and z=4
Putting these values in the given equation:
-15+(-x)+y
= -15+(-(-3)+6
= -15+3+6
= -15+9
= -6
A. it is a hexagon (there are 6 sides) B. using the equation (n-2)180 (where n is the number of sides we get (6-2)180=4*180=720. divide 720 by 6 to get 120 for each angle of the hexagon. (it has no irregularities in it's shape so that number will be correct for them all.) C. to get that just divide 39 by 6 to get 6.5 in per side. Hope that helps:)
The angular velocity is 16 radians per second
<u>Solution:</u>
The angular velocity of point is given by formula:
![w = \frac{v}{r}](https://tex.z-dn.net/?f=w%20%3D%20%5Cfrac%7Bv%7D%7Br%7D)
Where,
w is the angular velocity in radians
v is the linear velocity
r is the radius
Given that diameter of wheel is 10 feet
![radius=\frac{diameter}{2}](https://tex.z-dn.net/?f=radius%3D%5Cfrac%7Bdiameter%7D%7B2%7D)
![radius = \frac{10}{2}=5](https://tex.z-dn.net/?f=radius%20%3D%20%5Cfrac%7B10%7D%7B2%7D%3D5)
Thus radius is 5 feet
A point on the rim of a wheel moves with a velocity of 80 feet per second
Linear velocity = v = 80 feet per second
Therefore, angular velocity is given as:
![w = \frac{80}{5} = 16](https://tex.z-dn.net/?f=w%20%3D%20%5Cfrac%7B80%7D%7B5%7D%20%3D%2016)
Thus angular velocity is 16 radians per second
I don’t know but your in higher math than me so can you help me on my questions please. Sorry I know that seems kinda selfish but I need help. I know how you feel. No one will help me.
