It takes 15 minutes for the interior temperature of an oven to rise from 20°C to 180°C. A cake is placed in the oven for 25 minutes. When the cake is removed, the oven is turned off. The interior temperature of the oven returns to 20°C after 15 minutes. The oven is then turned on again, 45 minutes later. It takes 10 minutes for the temperature to reach 165°C. Cookies are placed in the oven to bake for 20 minutes. When the cookies are removed, the oven is turned off. The interior temperature of the oven returns to 20°C after 10 minutes. How can I make a line graph with this?

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 > ?
