Let f(x) = 2 to the x power. Show that a horizontal shift of k units is equivalent to scaling by a factor of 2 to the k power.

This is on the test review and may appear as a bonus, and I could seriously seriously use it. I just want to be a Bio teacher! This is my final math. Help me.

A bullet travelling horizontally at a speed of 350 m/s hits a board perpendicular to the surface, passes through it, and emerges on the other side at a speed of 210 m/s. If the board is 4.00 cm thick, how long does the bullet take to pass through it?
I also need an idea how it is worked.

Perpetual question more like....

right ..

I am wondering still, and still playing,

In my thought experiment yesterday, I mentioned an implausible type of machine, I would like to point out a few things about the idea, that I think may have been missed, and then have peoples thoughts on those, its a game really.

So my machine involved having a 1000 meter shaft , down which a House sized giant metal ball is dropped, this ball drops the thousand feet, and then goes onto a Mill type system that then turn tilts the top ball in the mill, (which is at the top of the 1000m shaft) and so the the next ball drops, and again descends down the shaft...

In my thought experiment, it is not the mill which we would derive the power from, the mill is a very well balanced mill, which just accepts a ball, the change in the weight, makes the mill turn and the next ball drop, this is all the mill does...
So there is no power to be lost there..

Some students wanted to find out if plants grew better when planted closer together or spaced far apart.In order to investigate this problem the students obtained 10 identical beanplans and labeled them pots A,B, and C.Pot A=1bean plant Pot B=3 bean plants Pot C=6 bean plants. Each plant was 50mm tall at the start and for ten days each pot was set in the same sunny window and fed 60ml of water daily. After the ten days were up the students noted that in the end the averge height in Pot A(1) was 155mm, the average height in pot B(3) was 99mm, and the average height in Pot C(6) was 78
1. What measurements did the students make and how often
2.What was the independent variable and why?
3.What was the dependent variable and why?
4.What was the control group in this experiment?
5.What was the experimental group in the experiment?
6.What quantitis would you plot in the horizontal axis and why?
7.And the vertical axis?

Is there a quality in their genome that increases their propensity to take clothes off for money. Likewise, would you be able to apply the same metric to all the French speaking dancers from Quebec?
