A student made an Arrhenius graph of Ln(k1/k2) versus 1/T (K-1). However she erroneously plotted 1/T on the Y axis instead of plotting 1/T on the X axis. She displayed the linear trendline to her graph in Excel. The equation of the trendline was Y = -0.000084*X  - 0.047. What was the value of the slope had she plotted the data correctly?

If the density of an object is 8.060 lb/ft3, then the density in SI units, is what? (1 lb = 454 g, 1 in = 2.54 cm, 1 ft = 12 in)

How would you round 0.0189787745 to 4 significant figures?

The world population in billions is approximately P = 7.4e0.010" where t is in years since 2016. Estimate the relative rate of change of population in 2020 using this model and the values of At below. Round your answers to three decimal places. (a) At = 1 The relative rate of change is % per year. the absolute tolerance is +/-0.001 (b) At = 0.1 The relative rate of change is % per year. (c) At = 0.01 The relative rate of change is % per year.

A blue whale has a length of 28,578 millimeters. what is the length of a blue whale in kilometers? Please show the different conversion factors used to solve. 

A group collected data in an experiment to learn to draw suitable trendline in a graph. They don't know the theoretical model, so they are trying to determine one through this experiment. They used Excel to display the data and to find good fit. They tried linear, exponential, and power trendlines. The result of each trial is shown below. The title of the plot contains the name of the trendline used to fit. What should be their analysis based on the result they have so far? Exponential trendline 20 Power trendline 18 y = 0.8374e047x R? = 0.9851 16 y = 0.8045x1.538. R2 = 0.981 15 14 12 10 10 ..... 4 ..... ....... 2 1 3 4 1 7 Linear trendline 20 y = 3.0209x - 4.6606 15 R? = 0.9293 10 ........ 2 4 6 8 The linear trendline is good fit The exponential trendline is good fit Any one of the three trendlines seems good candidate The power trendline is the best fit 2. 2.

A small light source located 1 m in front of a 1-m2 opening illuminates a wall behind. If the wall is 1 m behind the opening (2 m from the light source), the illuminated area covers 4 m2. How many square meters will be illuminated if the wall is 3 m from the light source? 5 m? 1 0 m?

The outside temperature can be estimated based on how fast crickets chirp. At 104 chirps per minute, the temperature is 6363 °F. At 176 chirps per minute, the temperature is 8181 °F. Using this information, you can make a formula that relates chirp rate to temperature. Assume the relationship is linear, that is the points form a straight line when plotted on a graph. What is the temperature if you hear 156156 chirps per minute?
