Determine the points in the interval (0,2pi) at which the graph of the function below has a horizontal tangent line. f(x) = 18 cos x + 9 sin 2x
(x, y)= (__ , __) (smallest x-value)
(x, y)= (__ , __)
(x, y)= (__ , __) ( largest x-value)

no, x cannot be the same number. in all of them, x is 1. for one input there is another output. g is not a function

give brainliest

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
