The green bars are called "error bars." They indicate the range of uncertainty that scientists have about the data on the graph.
(Note: Not all error bars are shown.)
Why do you think these error bars are smaller near the year 2000 than in the 1890s?

<u>Sum of Vectors in the Plane</u>
Given two vectors
They can be expressed in their rectangular components as
The sum of both vectors can be done by adding individually its components
If the vectors are given as a magnitude and an angle , each component can be found as
The first vector has a magnitude of 3.14 m and an angle of 30°, so
The second vector has a magnitude of 2.71 m and an angle of -60°, so
The sum of the vectors is
Finally, we compute the magnitude of the sum
