Tara shouldn't use the fertilizer because the plant with the fertilizer had a growth rate of 3.1 millimeters per day and the plant without the fertilizer had a growth rate of 3.4 millimeters per day.
Step-by-step explanation:
This is basically a slope problem.
The equation for slope is y1-y2/x1-x2
So take two points. Time would be your X. Height would be your Y.
I chose
6 - 18.6
8 - 24.8
So: 24.8-18.6/8-6 = 3.1 The slope of the growth of the plant is 3.1 mm per day.
If you started at W and went all the way around the circle until you wound up back at W, you will have gone 360 degrees. Since the angle measurement that prevents that is 85 degrees, the answer must be 360 - 85 = 275.
