A. Write a linear inequality that describes the situation.
B. Graph the linear inequality.
C. What is the maximum number of tickets that could have been sold for $2?
D. What is the maximum number of tickets that could have been sold for $3?

13. At most 500 ft. of fencing is available for a steer pasture. There is only space for the pasture to be at most 100 ft. wide.

I read somewhere that the sun revolves around the milkyway, is this correct?
Does the milkyway move at all...?
When the sun moves, is it always orbiting the same pathway? Or does it continue to orbit the milkway but have the milkway move and therefor always be in a different spot?

Im asking this because if the Earth Orbits the Sun, and the Sun orbits the milkway, does the milkway orbit something or move at all?
If it does, that could mean we are traveling all around space and never be in the same spot in space.

Maybe in thousands of years, if we move with the milkway we may discover something. Something different in space... maybe we could colide with another solar system? Or get caught in another solar systems orbit?

That question probably confused everyone cause im not good with my words, but please try and answer it...
thanks

I used this to determine the velocity of the putter at the impact point:


PE + KE (top of putter backswing) = PE + KE (bottom of putter swing-when it is vertical and impacting the ball)


H=.055m (this is based on a 20 degree backswing from vertical position)

g=9.8m/s^2

m=.46kg


(H*G*M)+KE(top)= 0+1/2(M)(V^2)

(.055m)(9.8m/s^2)(.46kg) + 0 = 0 + 1/2(.45kg)(V^2)

(.243kg*m^2/S^2)=(.225kg)(V^2)

V=1.05m/s


Coefficient of friction:

.105 for this surface


Impulse time at putter impact with golf ball:

.005 seconds
