Julia finds that the data in the table can be modeled by the function y = 5(4)x.

a 2-column table with 5 rows. the first column is labeled time (minutes) with entries 0, 1, 2, 4, 8. the second column is labeled distance (feet) with entries 5, 20, 80, 320, 640.
which statement about julia’s finding is true?

julia is correct because the distance starts at 5 feet and increases by a factor of 4.
julia is correct because the function is true for (0, 5) and (1, 20).
julia is not correct because the function is not true for the point (2, 80).
julia is not correct because the distance does not increase by a constant factor each minute.

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α. part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part b suppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
