- The results of this program are shown in the following table. The population change is the number of deer born minus the number of deer that died during that year. The herd population started at 2000 when this study began. Calculate the number of deaths (predation + starvation). To determine the deer population change, subtract the number of deaths from births (births - deaths), this can be a positive number, indicating growth, ora negative number which indicates a population decline. Calculate the deer population by adding/subtracting the population change from the population the year before The first row (1971) has been completed for you as an example.

(Remember to paste the unrounded function model into your calculator before reporting the answer with all numerical values rounded to three decimal places.) p(x) dollars per job gives the average amount the painter was paid perjob x years after 2004, 0 s x 6 (b) The equation for the painter's annual income is t(x) -Select dollars. (c) What was the painter's income in 2010? (Remember to avoid…arrow_forwardThe bar graph on the right shows the average cost of room and board at four-year public and private colleges for four selected years from 2011 through 2017. The data can be modeled by f(x)= 965x+3339 and g(x)= 3936 e136X in which f(x) and g(x) represent the average cost of room and board at public four-year colleges in the school year ending x years after 2010. Use these functions to complete parts (a) through (c) below.
