A scientist plots a vector on a coordinate grid to record the movement of a migrating whale. The units of the coordinate grid are kilometers, and the positive y -axis on the coordinate grid points north. The vector has initial point (0,0) and terminal point (5,12) . What are the approximate distance and direction of the whale’s movement? A 13 kilometers, 65° north of east B 17 kilometers, 67° north of east C 13 kilometers, 67° north of east D 17 kilometers, 65° north of east

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?
