- Think About It In Exercises 33 and 34, use the graph to determine whether y varies directly as some power of x or inversely as some power of x. Explain.arrow_forwardCalculus I Find the second derivative.arrow_forwardA trigonometric function models the monthly rainfall of a city, which reaches a maximum monthly rainfall of 8 inches in the spring and fall and a minimum monthly rainfall of 0 inches in the summer and winter. If r(t) models the monthly rainfall t months from when the monthly rainfall started being recorded for the city, what is the domain of function r?arrow_forward
- Linear functions are helpful in the study of statistics because a.they approximate complex functions with easy functions b.Not true, they are just for college algebra class c.y=mx + b d.Not true, just whip out a calculator to get whatever answer you need.arrow_forwardHOW DO YOU SEE IT? Consider an anglein standard position with r = 12 centimeters,as shown in the figure. Describe the changesin the values of x, y, sin θ, cos θ, and tan θas θ increases continuously from 0° to 90°.arrow_forwardThe Figure (see attached) shows a cylindrical soft-drink can. The can is to have a volume of 12 fluid ounces, approximately 22 cubic inches. Express the surface area of the can, A, in square inches, as a function of its radius, r, in inches.arrow_forward
