Petunia bought two plants she placed the first plant which was 20 inches tall, on the windowsill she noticed that the plant was growing at the rate of 1 inch per week. y=x+20

she placed the 2nd plant which was 5 inches tall on the coffee table, she noticed that it was growing at the rate of 2 inches per week,
y=2x+5
the heights of the two plants are shown in a graph
how many weeks will it take for the plants to reach the same height
a : 5
b : 10
c: 15
d :20

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 bsuppose 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 cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
