Statistics report that the baby mortality rate from 1971 to 1995 can be modelled through the equation of D=6(0.96n). Where D represents the number of deaths per 1000 in children under 1 year of age. n represents the number of years since 1995.
a) Indicate if the infant mortality rate is increasing or decreasing and explain your reasoning.
b)If the trend continues what will the infant mortality rate be in the year 2008?
c) When would the infant mortality rate be 3 per 1000? explain
Use the model given to answer the questions about the object or process being modeled. Arizonans use an average of 50 gal of water per person each day. The number of gallons W of water used by x Arizonans each day is modeled by
W = 50x.
(a) Make a table that gives the number of gallons of water used for each 1000-person change in population, from 0 to 5000.
Population

Depreciation is the decrease or loss in value of an item due to age, wear, or market conditions. We usually
consider depreciation on expensive items like cars. Businesses use depreciation as a loss when calculating
their income and taxes.
One company buys a new bulldozer for $124850. The company depreciates the bulldozer linearly over its
useful life of 20 years. Its salvage value at the end of 20 years is $12850.
A) Express the value of the bulldozer, V, in terms of its age, t. V =
B) The value of the bulldozer after 10 years is Ş
