Where x is the diameter of the wire in mils (0.001 inch).
(a) Complete the table.
(b) Use the table of values in part (a) to sketch a graph of the model. Then use your graph to estimate the resistance when
(c) Use the model to confirm algebraically the estimate you found in part (b).
(d) What can you conclude about the relationship between the diameter of the copper wire and the resistance?

They test the gun's rifling (the grooves in the bullet as it travels down the barrel of the gun) by comparing it to that of a second bullet fired into a bale of paper. The speed, s, in centimeters per second, that the bullet travels through the paper is given by s=50(3-10t), where t is the time after the bullet strikes the bale and ts0.3 second. (a) Complete the following table to find the speed for the given values of t. 0.1 0.2 0.3 s (cm/sec) (Type an integer or a decimal.)arrow_forward
