11. Use the graph below to answer the following question. What is the equation of the piecewise function in the graph above. (Hint: treat the portions from - 2 < x < 4 \: and \: x > 4−24 as two quadratic functions)

Nthe opening scene of the movie raiders of the lost ark, indiana jones replaces a golden statue with a bag of sand. the platform on which the statue is placed is designed to detect the mass of the statue. if the bag of sand has a different mass than the statue, then a mechanism triggers and destruction ensues. the density of gold is about 20\text{ g/cm}^320 g/cm 3 20, space, g, slash, c, m, start superscript, 3, end superscript. the density of sand can be estimated at 2.5\text{ g/cm}^32.5 g/cm 3 2, point, 5, space, g, slash, c, m, start superscript, 3, end superscript. the gold statue can be modeled as a cylinder with height 25\text{ cm}25 cm25, space, c, m and radius 8\text{ cm}8 cm8, space, c, m. in terms of \piπpi, what is the mass of sand indiana jones needs to avoid triggering the mechanism?

Myra took a picture of the sky one afternoon when two jet airplanes appeared to draw a pair of parallel lines with their vapor trails. the vapor trails from two other jets flying from another direction crossed over the parallel trails. she printed her picture and labeled the angles and lines. assume lines c and d are parallel and 2 measures 98°. which statements are true? check all that apply. 3 = 6 = 98° 3 = 14 = 98° 4 = 8 = 82° 4 = 12 = 82° 5 = 8 = 82°
