To find: The statement which is supported by the table.

Answer to Problem 42STP
The statement which is supported by the table is
C) The budget increased 20% from 2011 to 2012.
Explanation of Solution
Given information:The table shows the budget of a city.
Annual budget | |
Year | Budget (millions of $) |
2009 | 45.6 |
2010 | 48.3 |
2011 | 45.9 |
2012 | 55.1 |
The budget increased from the year 2009 to 2010 and then decreased from 2010 to 2011.
Thus, the statement “A)the budget decreased and then increased” is not supported by the table.
Percentage of budget increase from 2009 to 2010
Percentage of budget decrease from 2010 to 2011
Percentage of budget increase from 2011 to 2012
The greatest percentage of change occurred from 2011 to 2012.
Thus, the statement “B) the greatest percentage of change occurred from 2009 to 2010” is not supported by the table.
Percentage of budget increase from 2011 to 2012
Thus, the statement “C) the budget increased 20% from 2011 to 2012” is supported by the table.
Percentage of change from 2009 to 2010
Percentage of change from 2011 to 2012
Thus, the statement “D) the percentage of change from 2009 to 2010 was the same as from 2011 to 2012” is not supported by the table.
Conclusion:
The statement “C) the budget increased 20% from 2011 to 2012” is supported by the table.

Enterarrow_forwardYou are given a plane Π in R3 defined by two vectors, p1 and p2, and a subspace W in R3 spanned by twovectors, w1 and w2. Your task is to project the plane Π onto the subspace W.First, answer the question of what the projection matrix is that projects onto the subspace W and how toapply it to find the desired projection. Second, approach the task in a different way by using the Gram-Schmidtmethod to find an orthonormal basis for subspace W, before then using the resulting basis vectors for theprojection.
