An antique automobile is depreciating, i.e. losing value i.e. going down in price at a rate of 7% per annum compounded annually. Betty and Bob have an account, which earns interest at a rate of 12% per annum continuously compounded. They originally had $9,000 in the account and withdrew $2000 after the second year and $2,500 after the third year. They had enough money (exactly) to buy the automobile after 6 years.
Algebraically find the original value of the automobile.

Which method is better for purifying a mixture of two liquids that boil at nearly the same temperature: simple distillation of fractional distillation? Explain your answer (Hint: your answer should explain the term "theoretical plates" and how they apply in this situation).

13. For a computer, you are given the following parameters:

Average memory access time in the absence of paging (i.e., a single physical memory access time, which is computed by considering the main memory access time and the CPU’s L1 cache): 80 ns

TLB access time: 2 ns

TLB hit ratio: 75%

Note that all PTE’s are stored in main memory. There is NO disk access. CPU’s L1 cache is the hardware cache on the CPU chip for accelerating memory accesses.

- Assuming a 1-level page table (PT), what would be the average memory access time with paging enabled? Show your work.

- Assuming a 2-level PT, what would be the average memory access time

with paging enabled? Show your work.

A sample of 6.33 g of solid calcium hydroxide is added to 28.0 mL of 0.500 M aqueous hydrochloric acid. Enter the balanced chemical equation for the reaction.

What are the limiting reactant?

How many grams of salt are formed after the reaction is complete?

(a) Write the function rowSum() that receives a(double type) two-dimensional array using vectors and returns a vector consisting of the sum of elements in each row of the two-dimensional structure. The value of the returned vector at index zero is the sum of the elements in row zero of the two-dimensional structures. At index one of the returned vector is the sum of the elements in row one and so on. (b) Write a main function to test rowSum () function. Create a two-dimensional vector of at least size (5 x 5). Display the array and the content of the returned vector.

Compare the structure of xylenol orange to phenolphthalein. Do some research to determine why phenolphthalein changes color under acidic or basic conditions. Based on the chemistry of phenolphthalein, explain why xylenol orange is a different color in the presence and absence of zinc ions. It is useful to note that the xylenol orange-zinc complex that is red must absorb light around 500-550 nm while the free xylenol orange molecule is yellow, so must absorb light around 400-450 nm.

• Draw a diagram including your chosen coordinate system.

• Label all quantities in the diagram using standard notation.

• List the known and unknown quantities. Circle the unknowns.

• Identify the equation you are using and show all your work. • At the end of each problem, check your answer. Do the units match? Is the answer reasonable? Does the plus or minus sign make sense?

3. In the Daytona 500 auto race, a Ford Thunderbird and a Mercedes Benz are moving side by side down a straightaway at 71.5 m/s. The driver of the Thunderbird realizes that she must make a pit stop, and she smoothly slows to a stop over a distance of 250 m. She spends 5.00 s in the pit and then accelerates out, reaching her previous speed of 71.5 m/s after a distance of 350 m. At this point, how far has the Thunderbird fallen behind the Mercedes Benz, which has continued at a constant speed?
