Apoint is moving along the graph of a given function such that dx/dt is 2 centimeters per second. find dy/dt for the given values of x.
y = 9x2 + 5
(a) x = -1
dy/dt = cm/sec

(b) x = 0
dy/dt =/sec

(c) x = 3
dy/dt = cm/sec

Idon’t understand this.. will someone ? will mark brainliest along with 20 points.

The random variable x is the number of occurrences of an event over an interval of ten minutes. it can be assumed that the probability of an occurrence is the same in any two-time periods of an equal length. it is known that the mean number of occurrences in ten minutes is 5.3. the appropriate probability distribution for the random variable

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
