b.

Answer to Problem 45E
In march month the trash that was recycled was greatest.
Explanation of Solution
Given information: The table shows monthly amounts of trash and recycled trash at a school.
Calculation: Let’s find the fraction of recycled trash in decimals,
Month | Total trash (Ib) | Recycled trash (Ib) | The fraction of recycled trash in decimals |
Nov | |||
Dec | |||
Jan | |||
Feb | |||
Mar |
Hence, In march month the trash that was recycled was greatest.
To find: The effect the plant had on the recycling efforts in January and followed month.

Answer to Problem 45E
A new recycling had introduced the fraction of trash will be increase.
Explanation of Solution
Given information: The table shows monthly amounts of trash and recycled trash at a school.
As of January 1, a new recycling plan was introduced at the school.
Calculation: Since, A new recycling had introduced the fraction of trash will be increase.

What is the phase shift for y = 2sin(2x-)? 2. What is the amplitude of y = 7cos(2x+л)? 3. What is the period of y = sin(3x-π)? Directions: For problems 4 and 5, you were to compare and contrast the two functions in each problem situation. Be sure to include a discussion of similarities and differences for the periods, amplitudes, y-minimums, y-maximums, and any phase shift between the two graphs.
