12. The temperature of a small pudding was -4°C when taken out of the freezer. The pudding was immediately warmed in a saucepan, and after 8 minutes its temperature was 16°C. (a) By how much had the temperature risen during the 8 minutes? (b) Given that the temperature of the pudding increased at a constant rate, calculate (i) the number of minutes it had warmed when its temperature reached 0°C, (ii) its temperature when it had been warmed for a total of 24 minutes.​

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 > ?
