D An evergreen nursery usually sells a certain shrub after 4 years of growth and shaping. The growth rate during those 4 years is a time in years and h is the height in centimeters. The seedlings are 14 centimeters tall when planted (t = 0). Find the height after Oh(t) = 0.25t² +20t Oh(t)=0.5t+20 Oh(t) = 0.25t² +6t+14 Oh(t) = 0.25t+14 Oh(t)=0.51² +6t+14 Question 18 Use left endpoints and 10 rectangles to find the approximation of the area of the region between the graph of the function 3x² Round your answer to the nearest integer.

The fox population in a certain region has a continuous growth rate of 9 percent per year. It is estimated that the population in the year 2000 was 21800. (a) Find a function that models the population t years after 2000 (t = 0 for 2000). 0 for Your answer is P(t) (b) Use the function from part (a) to estimate the fox population in the year 2008. Your answer is (the answer must be an integer)
