There were 417 cell phones sold at an electronics store in January. Since then, cell phone sales at this store have increased at a rate of 3.75% per month. At this rate of growth, which function can be used to determine the monthly cell phone sales m months after January?

• p(m) = 417(0.0375)^m

• p(m) = 417(1.0375)^m

• p(m) = 417(0.9625)^{(m + 1)}

• p(m) = 417(0.0375)^{(m + 1)}

Convert x² - 9x + 20 to factored form and solve.

• (x-10)(x+2); x = -2, 10
• (x+4)(x+5); x = -5, -4
• (x-4)(x-5); x = 4, 5
• Not factorable
