Consider the objects labeled A, B, C, and D shown in the figure. A Object A consists of four sticks. The sticks coincide at their centers and make a 45 degree angle with their neighbors, such that the resulting object looks like an X atop a plus. The black dot is at the center where the sticks coincide. B Object B consists of two sticks. One stick is oriented horizontally. The other stick is oriented vertically, and extends upward from the midpoint of the horizontal stick. The black dot is at the midpoint of the horizontal stick where the two sticks join. C Object C is two horizontal sticks joined end to end. The black dot is at the right end of the right stick. D Object D contains three sticks. Two sticks are oriented horizontally and joined end to end as in object C. One stick is oriented vertically, and extends upward from the center of the horizontal stick on the left, as in Object B. The black dot is at the midpoint of the left horizontal stick where it joins the vertical stick. Each object is composed of identical thin sticks of uniformly distributed mass 6.03 kg and length 0.303 m . What are the moments of inertia I A , I B , I C , and I D of the objects about a rotation axis perpendicular to the screen and passing through the black dot displayed on each object?

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
