  1. BELL-WORK • A sequence is defined recursively by the equation an=an−1+3, where a1=0. Write an explicit formula for the sequence. • Find the fifth term of the sequence an = n∙an – 1; a1 = -1 • Suppose the acreage of forest is decreasing by 1.5% per year because of development. If there are currently 4.5 million acres of forest, write an exponential function to model the situation. Determine, to the nearest acre, the amount of forest land after 5 years. • Identify the initial amount and interpret the growth factor in the following exponential equations: (a) y = 12∙(0.45)x (b) y = 4∙(6)x

  17. Review Parallel and Perpendicular Use the map to answer the following. Show your work. a. City contractors would like to build a library on a road that is parallel to Hope Road at the indicated spot. They will call that street Peach Street. What is the equation on Peach Street? b. City contractors would like to build a gym on a road that is perpendicular to Elm Street at the indicated spot. They will call that street Power Street. What is the equation on Power Street?

  18. Review Writing an exponential equation Erika buys a television. The value of the television after being owned different numbers of years is shown in the table below. Write an exponential function that models the value, V, in dollars, of the television after t years of being owned.

  19. Review Compound Interest What is the value of a $550 investment after 3 years with an interest rate of 4% compounded semi-annually? Real-World Absolut value inequalities The ideal width of a safety belt strap for a certain automobile is 5 cm. An actual width can vary by at most 0.35 cm. Write and solve an absolute value inequality for the range of acceptable widths.
