The two-dimensional velocity field for an incompressible newtonian fluid is described by the relationship v = (12xy2 − 6x 3 )i + (18x 2 y − 4y 3 )j where the velocity has units of m/s when x and y are in meters. determine the stresses σxx, σyy, and τxy at the point x = 0.5 m, y = 1.0 m if pressure at this point is 6 kpa and the fluid is glycerin at 20 °c.

Liesl grew 7/12 of a foot in one year. her little sister grew 1/3 of a foot during that same year. how much more did liesl grow than her little sister did

If the graphs of the linear equations in a system are parallel, what does that mean about the possible solution(s) of the system? a. there are infinitely many solutions. b. there is no solution. c. there is exactly one solution. d. the lines in a system cannot be parallel.

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98
