The equation S=C(1+r/100)^5 is to find the inflated cost S, in 5 years, of an item, good or service, where C is the current price of that item in that country's currency and where the inflati

    Transformation of graphs

    Please see an attachment. 1) Describe the transformations on the following graph of f(x) = e^x . State the placement of the horizontal asymptote and y-intercept after the transformation. For example, left 1 or rotated about the y-axis are descriptions. a) g(x) = e^x - 2 b) h(x) = - e^x 2) Describe the transformations

    Approximation of Pi Using Inscribed Polygons: Archimedes

    Archimedes found his approximation to Pi by inscribed polygons. Start with a circle of radius 1 and a suitable starting polygon and solve for an inscribed polygon of 96 sides. Next, start with a unit circle and appropriate inscribed regular polygon to approximate Pi using a regular inscribed n-gon with 4096 sides.
