Helen has been working on a science project about plant growth. plant a started at a height of 6 cm and exhibited steady growth during the first four weeks of the project. after those four weeks, plant a was 26.8 cm in height.

in a linear model of plant a's growth, x represents the number of weeks after being planted, and y represents the plant's height in centimeters.

relative to this model, which of the following statements applies?

Given the choice between receiving $1.000.000 in one month or a single penny-doubled everyday for the period of one month; which option would you choice? show your work to support your answer. (assume that 1 month=30 days)

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.

Which of the following are accepted without proof in a logical system? check all that apply.
