An environmentalist monitored the water quality of a river in city Xby measuring the conductivity of the river monthly. The conductivity of a water body is an early indicator of the water quality. Owing to implementation of activities which were harmful to the nature such as an oil spill, the conductivity in µS/cm of the river decreased. However, a continuous cleaning up plan had been carried out for the river from January until April 2020 and the conductivity measurement for the months had improved as follows: a1, a2, a3, a4, a5…, an 3, 12, 27, 48, 75, …., an 1. Let an represents the conductivity for nmonths since January 2020. By using n in the formula, determine the formula to represent the conductivity sequence, an. 2.What is the estimated conductivity for January 2021? 3. By assuming bn-1= an - an-1, the monthly improvement of conductivity can be represented by the following sequence. Based on the given sequence, determine bn. b1, b2, b3, b4, …, bn = (12-3), (27-12), (48-27),…

In an experiment designed to monitor impedance to leg movement, Korean engineers attached electrodes to the ankles and knees of volunteers. Of interest were the voltage readings between pairs of electrodes. These readings were used to determine the signal-to nose ration (SNR) of impedance changes such as knee flexes and hip extensions.a). Six voltage electrodes were attached to key parts of the ankle. How many electrode pairs on the ankle are possible?b). Ten voltage electrodes were attached to key parts of the knee. How many electrode pairs on the ankle are possible?c). Determine the number of possible electrode pairs such that one electrode is attached to the knee and one is attached to the ankle.
