In the human arm, the forearm and hand pivot about the elbow joint. consider a simplified model in which the biceps muscle is attached to the forearm 3.80 cm from the elbow joint. assume that the person's hand and forearm together weigh 15.0 n and that their center of gravity is 15.0 cm from the elbow (not quite halfway to the hand). the forearm is held horizontally at a right angle to the upper arm, with the biceps muscle exerting its force perpendicular to the forearm.

The swimming pool is open when the high temperature is higher than 20∘c. lainey tried to swim on monday and thursday (which was 3 days later). the pool was open on monday, but it was closed on thursday. the high temperature was 30∘c on monday, but decreased at a constant rate in the next 3 days. write an inequality to determine the rate of temperature decrease in degrees celsius per day, d, from monday to thursday.
