The amount of growth of plants in an ungrazed pasture is a function of the amount of plant biomass already present and the amount of rainfall.t For a pasture in the arid zone of Australia, the following formula gives an approximation of the growth.
Y = -55.12 - 0.01535N - 0.00056N? + 3.946R
Here Ris the amount of rainfall, in millimeters, over a 3-month period, Nis the plant biomass, in kilograms per hectare, at the beginning of that period, and Y is the growth, in kilograms per hectare, of the biomass over that period. (For comparison, 100 millimeters is about 3.9 inches, and 100
kilograms per hectare is about 89 pounds per acre.)
Now we consider the amount of growth Y as a function of the amount of plant biomass N already present.
(a) First we assume that the rainfall is 80 millimeters, so R = 80.
(1) Find a formula for the growth Y as a function of the amount N of plant biomass already present.
kg/ha
(ii) Make a graph of Y versus N. Include biomass levels N from 0 to 800 kilograms…
A ball is dropped from the top of a lighthouse that is 145 feet above sea level. The height
(position) of the ball after t seconds can be found using the function
s(t) = -16t² + 145
Write all answers in decimal form, rounded to three decimal places where appropriate.
A. Find the average rate of change of the ball on the interval from 1 to 1.5 seconds. Include
the units.
B. Find the instantaneous rate of change of the ball 2 seconds after it is dropped. Include
the units.
C. Find the height of the ball 2 seconds after it is dropped. Include the units.
Type your answers into the box below. Be sure to label your answers A, B, and C.
