A material has an initial quantity of 15 units. Which equation models the amount of the material, y, decaying exponentially at a rate of 23% over time, X? y = 23(1.15)
y = 23(.85)x
y = 15(1.23)x
y = 15(.77)x

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

the diver is 33 feet below the surface.
