Determine a function, f, such that G = fog if g and G are defined as follows: . , and G(x) - DETAILS 13, 14. [-14 Points] Find a function, f, so that H = fog oh where f(x) = [-/5 points] 5 + IXI , g(x) = 6 + x, and h(x) = lxl. DETAILS MY NOTES MY NOTES ASK YOUR TEACHER ASK YOUR TEACHER A stone is dropped into a lake, creating a circular ripple that travels outward at a speed of 40 cm/s. (a) Express the radius r of this circle as a function of the time t (in seconds). (b) If A is the area of this circle as a function of the radius, find A o r. Interpret the answer found in part (b). O O O This formula gives the extent of the rippled area (in cm2) at any time t. This formula gives the circumference of the rippled area (in cm) at any time t. This formula gives the radius of the rippled area (in cm) at any time t.
