Given the equation 1(x-1)(x+1)=Ax-1+Bx+1, find A.

In the case of forensics, we saw a difference between data collected under ideal conditions in contrast to data collected from a chaotic crime scene (for example, fingerprints from a digital scanner vs. fingerprints from an object at a crime scene). Similarly, in biology we see differences between data collected in a controlled lab environment versus data collected in an uncontrolled natural environment. Good science can be done under both conditions, but data from real-world environments must acknowledge which of the following?

A scientist measured a sample of mercury after an experiment and this weighed 0.000045 kg. He wrote the value 4.5 × 10-4 kg in his report. Did he write the correct value in scientific notation? If not, what should it be?

A 0.15 kg hockey puck moving east at 8.0 m/s collides with a stationary 0.20 kg puck. After collision, the first puck moves at 4.0 m/s at 35° north of east. (a) Determine the velocity components of the second puck after collision. (b) Determine its magnitude and direction. (c) Explain why momentum must be conserved separately in the x and y directions.
