(a)
To calculate: The stockpiles in each of the next two years, if in an arm race is held between two superpowers, each nation stores its own enemy’s nuclear arsenal each year and has a policy of undoing a certain percentage of its stockpile each year and adding that same percentage of its competitor’s stockpile.
Nation A has
(b)
To calculate: The stockpiles in each of the preceding two years, if in an arm race which is held between two superpowers, each nation stores its own enemy’s nuclear arsenal each year and has a policy of undoing a certain percentage of its stockpile each year and adding that same percentage of its competitor’s stockpile.
Nation A has
(c)
To prove: That the missile gap is decreased by

- 2. Suppose that in Example 2.27, 400 units of food A, 500 units of B, and 600 units of C are placed in the test tube each day and the data on daily food consumption by the bacteria (in units per day) are as shown in Table 2.7. How many bacteria of each strain can coexist in the test tube and consume all of the food? Table 2.7 Bacteria Strain I Bacteria Strain II Bacteria Strain III Food A 1 2 0 Food B 2 1 3 Food C 1 1 1arrow_forwardCell Phone Plans Gwendolyn is mulling over the three cell phone plans shown in the table. Gigabytes GB of data included Monthly Cost Each additional megabytes MB Plan A Plan B Plan C 1 1 1 25.00 40.00 60.00 2.00 1.50 1.00 From past experience, Gwendolyn knows that she will always use more than 1GB of cell phone data every month. aMake table of values that shows the cost of each plan for 1 GB to 4 GB, in 500 MB increments. bFind formulas that give Gwendolyns monthly cost for each plan, assuming that she uses x gigabytes of data per month where x1. cWhat is the charge from each plan when Gwendolyn uses 2.2 GB? 3.7 GB? 4.9 GB? d Use your formulas from part b to determine the number of gigabytes of data usage for which: (i) Plan A and Plan B give the same cost. (ii) Plan A and Plan C give the same cost. (iii) Plan B and Plan C give the same cost.arrow_forward
