Mr and Mrs A are 120 km apart. A bee is on Mr A's nose.The couple cycle towards each others, Mr A at 25 km/h and Mrs A 15km/h. The bee dashes from Mr A's nose to Mrs A's nose and back again and so on at 60 km/h.
HOW FAR DOES THE BEE TRAVEL BEFORE THE CYCLISTS CRASH?
p/s Please put your answers with your solutions. Thanks for answers.

I'll use the letter v to symbolize a down arrow... not sure how else to type logs..... ^ means up.

1) Rewrite as a single logarithm: 3 logv4^x - logv4^y

2) Which _expression is = to logv8[5(x-4)]
a) logv8^5x - logv8^20
b) 5 logv8^(x-4)
c) logv8^x
d) logv8^5 + logv8^(x-4)

3) Find the value of these logs
a) logv1/2^(1/8)
b) Logv3^(1/3)

4) Which _expression(s) are = to 2?
a) logv3^16 - logv3^4
b) logv4^4^2
c) logv6^1 + logv6^1

5) Use the log of a quotient property to rewrite logv5^(1/8)

6) If y = 8^x, what is its inverse function? My guess is -8^x but who knows. Choices -

a) y = logv8^x
b) y = 8^-x
c) y = -8^x
d) y = 1/8^x

What's the big mystery about math that makes it so hard to a lot of people. How the formualas are made should be no mystery. Theres a reason why the formulas are made the way they are. The reasons that I think that people hate class is
1) People sleep in math class
2) You are taught be a person other than a math teacher, ex. a football coach, that can add 2 and 2 together in the first place.
So if someone would tell me why they hate math then I would understand better. I'm giving the points to a really good explaination.

numbers in time = music theory
numbers in space=geometry
numbers in time/space=astronomy
numbers unto themselves=mathmematics
So what is motion picture? numbers in what? One can argue that at least in part a movie is numbers in time. a movie is measured by length of time. right? but what is the CONTENT of the movie? They are numbers in what? time / space? but wait numbers in time/space is astronomy! so what is a motion picture of a symphony performance? music is numbers in time so what is a motion picture of numbers in time? and if i am watching a live performance of said symphony that is numbers in what? time right? but the symphony ,the producers of numbers in time ,encompasses three dimensional geometric space. but wait i thought numbers in time/space was once again astronomy? Is music, geometry, mathematics and astronomy all in the same? Pythagorus and the ancient Greeks thought so.

I see things better with images, not numbers.
So here is my questions;

1. I can visualize this. Draw a round circle, divide it by 1/2, and you get the circle split down the middle. No problem with this. Even when I divide it by 1/4 - 4 pieces.

2. How would I divide the round circle if the fraction was 4/16?

When I ask people who know math to do this for me, they walk away...

We can say that at least in part a movie equals numbers in time because a film is measured in lengths of time but but what about the CONTENT of a movie? What is its mathematical equivalent? Numbers in physical space? That ='s geometry. numbers in time/space? thats astronomy. Any ideas ?

A point M is moving in a 2D plan. Its coordinates are functions of time x(t) and y(t). The initial position of M at t=0 is known (x0, y0).

Constraint 1:
==========
M(x, y) moves along the curve y = ax^2 + bx + c

Constraint 2:
==========
The speed vector orientation of M will change but its length remains constant:
(dx/dt)^2 + (dy/dt)^2 = const

Question:
=======
How can we express x(t) and y(t)?
