The airport escalator is slightly out of sync with its handrails. The escalator moves at a speed of 40 inches per second, while the handrails moves at a slightly but annoyingly faster pace of 42 inches per second. The length of escalator is 140 feet. From the moment a person steps onto the escalator to the moment he steps off, how much farther (in inches) would the handrails have moved ahead of the escalator?

Atype of plant is introduced into an ecosystem and quickly begins to take over. a scientist counts the number of plants after mmonths and develops the equation p(m)= 19.3(1.089)^m to model the situation. most recently, the scientist counted 138 plants.assuming there are no limiting factors to the growth of the plants, about how many months have passed since the plants werefirst introduced? a)o 6.1b)0.6.6c)10 72d)o 23.1
