Ohh.............. Thanks! i get it!

Ok, I figured this out (I think) but can you please check? Don't worry. I can carry the tent all by myself because it is so light. I do not even need a lantern it is so light outside. In these sentences, the word "light" is used as a: A:homophone B:homonyme C:syn...

Calculus (urgent!!)
A particle moves with its position given by x=cos(2t) and y=sin(t), where positions are given in feet from the origin and time t is in seconds. A)Find the speed of the particle. Speed = ____________ (include units) B)Find the first positive time when the particle comes to a st...

Calculus (pleas help!!!)
Consider the parameterization of the unit circle given by x=cos(4t^2−t), y=sin(4t^2−t) for t in (−InF, INF). Describe in words and sketch how the circle is traced out, and use this to answer the following questions. (a) When is the parameterization tracing th...
