Hey Skeeter. I read his question as if he was looking for the actual dimensions of the objects. The masses of the block and penny are given.

That is correct.

Updated the question again with the location of the masses. However there are no sizes of the masses given

Hey sorry I missed that. I updated the question including the radius.

A penny of mass 3.10 g rests on a small 20.0-g block supported by a spinning disk. The block is sitting at the edge of the disc at a radius of 12 cm. If the coefficient of friction between block and disk are 0.750 (static) and 0.640 (kinetic) while those for the penny and block are 0.450...

Our functions give different outputs of the same x value. Your's looks accurate but what exactly is wrong with my function? I don't see why I can't multiply the fuel cost by the total litre's (450/(8-v/10))

If anyone also know's how to fix that font please do let me know.

[FONT=Arial][FONT=Arial]A truck crossing the prairies at constant speed of 110km per hour gets 8km per litre of gas. Gas costs 0.68 dollars per litre. The truck loses 0.10 km per litre in fuel efficiency for each km per hour increase in speed. Drivers are paid 35 dollars per hour in wages...

If a>1, a cannot = 1, x>0, show that Loga(1/x) = log1/x(a). (COULD NOT SOLVE)

Hey Olinguito, I'm a bit confused as to your steps...did you manipulate the left hand side or the right hand side? Also could you start from the given equation? I corrected part b). Thanks.

Prove: a) cos(sin-1x) = √(1-x2) b) cos-1a+cos-1​b = cos-1(ab-√(1-a2)√(1-b2) (edited) (VERY HARD)

If SinA + CosA = p and TanA + CotA = q, prove that q((p^2)-1) = 2. (Spent hours STILL could not figure out!)

What do the average velocities on the very short time intervals [2,2.01] and [1.99,2] approximate? What relationship does this suggest exist between a velocity on an interval [a,b] and a velocity near t=a+b/2 for this type of polynomial?

thank you so much

Also how do you go from Vi^2 / g to 0 degrees < theta < 90 degrees?
