World population (in billions) grows roughly according to the formula P = 2.5e0.018t where t is the number of years since 1950. According to this formula what will the world population be in 2050? (Express your answer to the nearest tenth of a billion.)

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
