what is the value of 3xy+2x when x=2 and y=3? (answer)

We are asked to find the value of the expression:   3xy + 2x  in the case where x = 2 and y = 3. This is a case of what I might call "numeric substition for variables".  It's a very important skill because it usually comes up at least once in many types of algebra and all kinds of science...

word problems (answer)

So you need to apply your equation:   T(t) = 35 + 41e-0.058 t   to find T.   They want you to figure out the temperature of the pudding, and they have told you they decided to call it T.   The notation T(t) means T is a function of t.  In this case, they have said...

Spoiler Alert: This post gives a lot of hints on how to do the problem about the famous bullwhip that I posted on Dec 3, 2012 under the heading “Sine of the times”. If you got stuck on the problem, read a hint and then give it another try. Only read another hint if you are still stuck. You might want to have someone read you the hints so that you do not accidentally read more hints than you... read more

Sine of the times

High school trigonometry students who are learning to solve triangles for missing sides and missing angles, here is a problem I made up for you: You and I and a famous adventurer with a hat and a bullwhip are in a bind. 20 yards straight west and behind him and two fellow explorers (me and you), across a gaping hole in the floor that has since opened up, a trap that he accidentally triggered... read more
