Shouldn't there be twice as many whole numbers (even and odd)
as there are just the even whole numbers?

Count even numbers (2, 4, 6, 8 ... ) = infinity.
Count whole numbers (1, 2, 3, 4 ...) = infinity

Infinity = Infinity ..... or does it?

At the speed of light, it seems to me, that time would stand still. At least, time as I know it to be. One degree faster, would then cause time to go in reverse, relative to where I'm at. At least, 'my time' would. Wouldn't it? So speed of light being, then, a reference point of time standing still. I could go a zillion miles one way and a gazillion another way at the same 'time'.? A few decades ago, I recall reading something like that in a book titled 'Cosmology'. Which described many people different theories.

The sides of an equilateral triangle are increasing at the rate of 27 in/sec. How fast is the triangle's area increasing when the sides of the triangle are each 18 inches long?

I got 420.88 in^2/sec

you don't have to compute it for me or anything, I just feel really uncertain of my answer, and I would like to know if I am doing it all wrong or not.

A 10kg box rests ona ramp that is laying flat. The coefficient of static friction ( µs ) is 0.50, and the coefficient of kinetic friction ( µk) is 0.30.....

what is the force (Fp) necessary to keep the box sliding at a CONSTANT VELOCITY?

I'm not really sure how to work this problem...this is the only thing i could come up with, but I dont think its right...could check this plz?

∑Fy = Fn - Fg = 0 , therefore
Fn = Fg = mg = 10kg*9.8m/s2 = 98N

∑Fx = Fp - Ffk = 0, therefore
Fp = Ffk = µk(Fn) = 0.30 (98N) = 29.4N


The reason why I think there might be something wrong with this is b/c i calculated the max static friction (Ffs) to be 49N...Im really confused could someone plz help me?
