The rate of change in an equation is the coefficient of x. EXAMPLE: y=3x+4 The rate of change is 3. To find the rate of change from a table choose two consecutive points and take the ratio of the change in outputs over the change in inputs. EXAMPLE: A man has a forearm of 15 and a goot length of 16. (15,16). A woman has a forearm of 11 and a foot length of 12. (11,12). The rate of change would be: (16 - 12) / (15 - 11) or 4/4 which is 1.

Determine whether the following statements are true and give an explanation or counterexample. bold a. when using the shell method, the axis of the cylindrical shells is parallel to the axis of revolution. bold b. if a region is revolved about the y-axis, then the shell method must be used. bold c. if a region is revolved about the x-axis, then in principle it is possible to use the disk/washer method and integrate with respect to x or the shell method and integrate with respect to y.

Jabari is power washing houses for a summer job. for every job, he charges an initial fee plus $30 for each hour of work. his total fee for a 4 -hour job, for instance, is $170 . jabari's total fee, f, for a single job is a function of the number, t, of hours it takes him to complete the job. write the function's formula.
