Let X = R2 and let d be the Euclidean metric. Define d3: R2 x R2 R by d3(x, y) min (1, d(x, y)). (This metric is sometimes called the "near- sighted" metric. Up to one unit away, every point is distinguished clearly. But past one, everything gets blurred together) A) Verify that d3 is a metric on R2.
B) Draw the neighborhoods N(0:), N(0:1), and N(0:2) for ds, where 0 is the origin in R2.

Merrida uses a pattern in the multiplication table below to find ratios that are equivalent to 7: 9. if merrida multiplies the first term, 7, by a factor of 6, what should she do to find the other term for the equivalent ratio? multiply 9 by 1. multiply 9 by 6. multiply 9 by 7. multiply 9 by 9.

Tom is the deli manager at a grocery store. he needs to schedule employee to staff the deli department for no more that 260 person-hours per week. tom has one part-time employee who works 20 person-hours per week. each full-time employee works 40 person-hours per week. write and inequality to determine n, the number of full-time employees tom may schedule, so that his employees work on more than 260 person-hours per week. graph the solution set to this inequality.
