A test car went 64 miles on 2 gallons of gas in the morning, 16 miles on ½ gallon at noon, and 32 miles on 1 gallon at 5 pm. Is the relationship a proportional relationship?

Maria solved an equation as shown below. what is the solution to maria’s equation?

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 > ?

Here is another math questions. i will keep asking different questions. 4^2x=6
