Google Shopping conversions are up to 2x higher than traditional search conversions. As a result, cost per clicks have continued to grow for Google Shopping while stabilizing for traditional search. Advertisers are bidding aggressively for Google Shopping placements since the revenue from clicks is 74% higher compared to traditional search. Shopping also generates 39% more revenue for Google than text ads alone on product pages. New bidding strategies are needed for Shopping to maximize bottom line profitability given differences in traffic and revenue reactions to bid changes.

Here are the steps to show that the given 3x3 array will always form a magic square for any values of a, b, c:
1) Each row sums to 3a.
2) Each column sums to a+b+c, a, and a-b+c.
3) The diagonals sum to a+b+c and a-b+c, which are equal.
Since each row, column and diagonal sums to the same value (3a for rows, a+b+c for columns/diagonals), the 3x3 array will always form a magic square for any integers a, b, c.

It emphasizes using graphing technology to experiment but not substitute for analytical work. Examples are provided to demonstrate finding maximums, minimums, intersections, and asymptotes of various functions. The key points are determining features of a curve from its defining function.
3.complex numbers Further Mathematics Zimbabwe Zimsec Cambridgealproelearning
This document introduces complex numbers and their algebra. It discusses how quadratic equations can lead to complex number solutions and how to represent complex numbers in the forms a + bi and rcis(θ). It then covers the basic arithmetic operations of addition, subtraction, multiplication and division of complex numbers. It provides examples of solving equations with complex number solutions. The key points are:
- Complex numbers allow solutions to quadratic equations that have no real number solutions.
- Complex numbers can be represented as a + bi or rcis(θ).
- Operations on complex numbers follow the same rules as real numbers but use i2 = -1.
- Equations with complex number variables can be solved using the same methods as real numbers
