I am not sure about the first but suspect you are correct. Yes on the second. Based on Abe Lincoln's experience with self education, I have to agree with the third, although it was not at all true in Massachusetts where I live.

**Algebra (Urgent)**

(1-3)/(3-1) = (y-1)/(x-3) -2/2 = -1 so -x+3 = y-1 y = -x + 4

sin^2 T = 1 - cos^2 T sin^2 T = 1 - 9/49 sin^2 T = 40/49 sin T = (2/7) sqrt 10 and tan T = sin T/cos T

**Physics**

I do not see any figure. His speed at the top is his horizontal speed, u, for the whole trip u = 28 m/s at takeoff v^2 = Vi^2 + u^2 where v is total speed and Vi is initial speed up so 29.5^2 = 28^2 + Vi^2 Vi = 9.29 m/s that is all I need to do the vertical problem easy with ...

**physics! description explanations**

By the way I am assuming that your curve is continuous and smooth. If there is an instantaneous change in slope (velocity), for example at 1 second, then the acceleration is infinite. a = (V2-V1)/0

everything is divided by one second for velocity I take position at n minus position at (n-1) for acceleration I take velocity during n+1 - velocity during n

every month multiply the price by 1.005 in other words price = 2.44 * 1.005^n where n is the number of months from now in 12 months price = 2.44 * 1.005^12 = 2.44 * 1.061678 = 2,59 then 5 = 2.44 *1.005^n or 2.04918 = 1.005^n tale log base 10 both sides .31158 = n ( .002166) n...

There do not seem to be any accelerations going on here. First cyclist: how long will he take" outbound: 20 km / 20km/h = 1 h inbound: 20 km / 15 km/hr = (4/3) h total time for C1 = (7/3) hour so Second cyclist must do 2x km at 10 km/hr in (7/3) hr 2 x = 10 km/hr * (7/3) ...

acceleration is rate of change of velocity (not speed) deceleration means negative acceleration I suppose, but a physicist just says negative acceleration. I would not use that word! so let's say I an going east at 10 m/sec if my acceleration is +2 m/s^2 east then in one ...

Well, if you have a table with values in two columns choose one column for x values and one for y values then for each pair, go right a distance x and up a distance y from the origin (0,0) and make an X Then connect the spots where you have Xs.
