There are 15 people in the chorus. Each year, the number of people in the chorus increases by 12%. There are 30 people in the band. Each year, 2 new people join the band. Part A: Write functions to represent the number of people in the chorus and the number of people in the band throughout the years. (4 points)

Part B: How many people are in the chorus after 9 years? How many people are in the band after the same number of years? (2 points)

Part C: After approximately how many years is the number of people in the chorus and number of people in the band the same? Justify your answer mathematically.

Sorry guys but as you have a small brain

To describe a sequence of transformations that maps triangle abc onto triangle a"b"c", a student starts with a reflection over the x-axis. how should the student complete the sequence of transformations to map triangle abc onto triangle a"b"c"? plz

To find the extreme values of a function f(x. y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x, y)=xy
