The speed of a wave during a tsunami can be calculated with the formula
where
S=square root of 19.812
s represents speed in meters per second, d represents the depth of the water in meters where
the disturbance (for example earthquake) takes place, and 9.81 m/s2 is the acceleration due to
gravity. If the speed of the wave is 150 m/s, what is the approximate depth of the water where
the disturbance took place?

A. plot the data for the functions f(x) and g(x) on a grid and connect the points. x -2 -1 0 1 2 f(x) 1/9 1/3 1 3 9 x -2 -1 0 1 2 g(x) -4 -2 0 2 4 b. which function could be described as exponential and which as linear? explain. c. if the functions continue with the same pattern, will the function values ever be equal? if so, give estimates for the value of x that will make the function values equals. if not, explain why the function values will never be equal.

Solve the inequaliy: (x^2+2)(x−2)^2(6−2x)> 0

Charlie is at an amusement park that has 18 different rides. each ride costs $1.75. the function c(r) = 1.75r represents the total amount of money that charlie will spend if he goes on r rides, but he never goes on the same one more than once. what domain and range are reasonable for the function?
