PLEASEE HELP. A parent function has the equation y1=(0.5)^x. Find the equation for y2 by transforming the original equation.
To form y2 there is first a vertical stretch such that the values are twice of those in y1 and the graph is shifted up 8 units.

To ? nd out how many students are unhappy with the dining hall food, you distribute a survey. which method of surveying would produce the least amount of bias in your data?

Asmall (but heavy) particle placed in a glass of water will follow a zigzag motion because the particle will bounce off of the water molecules it meets. this is called brownian motion. a physicist simulates this on a computer, by varying the distance a particle can travel (called the mean free length), on average, before it collides with a water molecule and assigning the change in motion to be one of 8 directions, each with a similar probability. by running the simulated particle (with the same mean free length) many times she determines that it should take 15 seconds, on average, for the particle to fall to the bottom, with a standard deviation of 1.5 seconds. next she lets a real particle fall through a glass of water and finds that it took 18 seconds. what does she conclude, and why?

In the figure shown below, m < 40 and ab =8. which equation could be used to find x?
