Use the market's hhi and the ftc's historical guidelines for mergers to answer the following question: suppose the top five firms in a market have market shares of 20%,15%,15%, 5% and 5% respectively. the remaining 40 firms in the market each have a market share of 1%. would the ftc be likely to approve a merger between the top two firms in this market?

An engine, weighing 3000 n, is supported on a pedestal mount. it has been observed that the engine induces vibration into the surrounding area through its pedestal at the maximum operating speed. determine the stiffness of the dynamic vibration absorber spring in (n/m) that will reduce the vibration when mounted on the pedestal. the magnitude of the exciting force is 250 n, and the amplitude of motion of the auxiliary mass is to be limited to 2 mm note: in this question type-in right numbers, no decimals, no fractions, no unit. approximate to right number if needed
