What is the slope of the tangent line to j (2 ) - 27 + 1at = = 27 Oa) 1.5 Ob) 2.8 O c 3.2 O d) 5.1 Question 65 (1 point) Listen For a science experiment, a student is throwing a watermelon from a cliff. The height of the watermelon can be modeled by the function h(t) = -4.9t2 + 12t + 150, where h(t) is measured in metres, and t is in seconds from the time it is thrown. What is the average rate of change during the time interval of 2 and 3.5 seconds after it is thrown? a) -0.07 m/s Ob) -15.0 m/s O c 15.0 m/s Od) 0.07 m/s Question 66 (1 point) Listen Let f(x) - log2 (x2 + 21 + 1) and g(z) = log,(r + 1), find h(I) = f(I) - g(I). Oa) h(z) = 0 Obj h(I) = log2(I + 1) Och(z) = 2log2 (2 + 1)
