If f and g are the functions whose graphs are shown, let u(x) = f(x)g(x) and v(x) = f(x)/g(x). g (a) Find u'(1). (b) Find v'(5).15. [-/1 Points] DETAILS SCALCET8 3.3.056. A semicircle with diameter PQ sits on an isosceles triangle PQR to form a region shaped like a two-dimensional ice-cream cone, as shown in the figure. If A(0) is the area of the semicircle and B(0) is the area of the triangle, find A(0) lim 0- 0+ B(0) A(0) P O B(0) 10 cm 10 cm R
