Create a scatter plot of your data from part A using the tool’s data feature. Then manually fit a variety of function types to the data, using the sliders for the given parent functions. Create a scatter plot of your data from part A using the tool’s data feature. Then manually fit a variety of function types to the data, using the sliders for the given parent functions. Be sure to adjust the upper and lower values of each slider before trying to fit a function to the plotted data. Narrowing the interval on the slider moves the function slowly and accurately. Widening the interval on the slider moves the function farther and more coarsely.

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?

Acertain population of bacteria demonstrates exponential growth doubles in size every 4 days. how long will it take the population to triple in size?

Expresa commuter train leaves downtown sation and travels at a average speed of 55 miles per hour towards the north side sation, which is 50miles away. thirty minutes later, express commuter train #7 leaves north side and travels at a average speed of 35miles per hour towards downtown sation. at the moment the two trains pass each other, how far(in miles) is train #12 from the downtown sation and how long(in minutes) has the #12 train been traveling
