QA At time t = 0, a boiled potato is taken from a pot on a stove and left to cool in a kitchen. The internal temperature of the potato is 91 degrees Celsius (°C) at time t = 0, and the internal temperature of the potato is greater than 27°C for all times t > 0. The internal temperature of the potato at time t minutes can be modeled by the function H that satisfies the differential equation dH (H- (H-27), where H(t) is dt measured in degrees Celsius and H(0) = 91. (a) Write an equation for the line tangent to the graph of Hat t = 0. Use this equation to approximate the internal temperature of the potato at time t = 3. (b) Use 2017 APⓇ CALCULUS AB FREE-RESPONSE QUESTIONS (a) dH d²H dt² to determine whether your answer in part (a) is an underestimate or an overestimate of the internal temperature of the potato at time t = 3. (c) For t < 10, an alternate model for the internal temperature of the potato at time 7 minutes is the function -= − (G - 27)²/3, where G(t) is measured in degrees Celsius dG G that satisfies the differential equation dt and G(0) = 91. Find an expression for G(t). Based on this model, what is the internal temperature of the potato at time t = 3 ? 564 at (21-27) - == 2-16 To = - = (H(3)-27) 4 -64 = HB)-27 -37 = H (3) (b) _d²fi © 2017 The College Board.

What are the three levels of a Linux system? What are the two main functions of the kernel? [Reading Text] UNIX was initially developed by researchers at Bell Labs in the 1970s. Today, UNIX and its variants are widely used mainly on servers. By far, the most well- known UNIX-like operating system is Linux. Linux is available in different distributions which include the Linux kernel and different collections of software. These distributions have various user interfaces, many experienced users preferring the command-line interface, or shell. Linux distributions include a range of software including text editors. memory. While the mechanics of Linux and other Unix operating systems are complicated, the components of a Linux system can be grouped into three levels. The lowest level is the hardware, such as Central Processing Unit (CPU) and The next level is the kernel. It enables communication between hardware and software, by providing instructions to the CPU and other hardware. The programs that are running on the system, or processes, make up the top level known as the user space. Processes in user space generally only have access to a restricted amount of memory and operations, this is called user mode. The kernel runs in kernel mode which allows it unrestricted access to hardware resources. The kernel provides functions such as process management and memory management. A computer only has limited Random Access Memory (RAM) and processor cores. Process management allows the system to run multiple programs (processes) at the same time even if the CPU can only execute only a few processes at a time. Memory management allows applications to share the system's memory while avoiding potential issues such as memory leak. Included with the kernel are device drivers that provide an interface for applications to communicate with hardware, such as hard drives. System calls allow user processes to access features that are executed at kernel mode, for example creating new processes.

CUTTING EDGE 1-05 絶滅危惧種の選定 Have you ever heard of the "quagga"? Perhaps not, but you may have seen a zebra before. (1)The zebra is a horse-like animal with 形M distinctive black and white stripes covering its body. The quagga was a member of the zebra family, brownish in colour with white stripes FOS around the neck and the front part of the body. (2)It is often said that quagga looked like "zebra which had forgotten to put on their pajama trousers." Quaggas lived in Southern Africa, but they died out in the 19th century due to overhunting. We can now only see their wild beauty as 3stuffed specimens. Some researchers, however, have tried to "revive" the quagga. Because of its attractive stripe pattern, the quagga has gathered much attention from those interested in animal conservation. Those who would like to see the animals walk around the savannas again have conducted the Quagga Project for over thirty years in South Africa. Fas 模様のない (3)It turns out that the quagga is genetically close to the plains zebra. In this project, researchers have attempted to selectively breed plains zebras: they chose plains zebras which have fewer stripes and look slightly like quaggas. Baby zebras born to a slightly quagga- like mother and father may look more like the quagga, with a 13 significantly reduced number of stripes. (4)This project has achieved a certain level of success, producing several lovely baby zebras which have striking similarities [to ] the quagga. . However, should we be happy about this? (5)While this new generation of zebras is visually impressive, it only resembles [X]

次の英文を読み, 設問に答えなさい。 Jaguars had called the American Continents their home since the Ice Age when their ascendents crossed the Bering Land Bridge that once joined what is now Alaska and Russia. They lived in the central mountains of the southwestern United States for hundreds of years until they were almost driven to extinction in the mid- 20th century after hunters shot the last one in the 1960s. Currently, jaguars are found in 19 different countries. Several males have been observed in Arizona and New Mexico over the last 20 years, but breeding pairs have not been seen or reported north of Mexico. Natural reestablishment of them is also unlikely because of urbanization and the U.S.-Mexico border blocking jaguar migration routes. Now, after more than a 50-year absence, conservation scientists are suggesting the jaguar's return to their native environment in a study that outlines what the rewilding effort may look like. The authors of the new paper suggest a suitable area for jaguars spanning 2 million acres from central Arizona to New Mexico. The space would provide a big enough range for 90 to 150 jaguars, the researchers explained. They also argued that bringing jaguars back to the U.S. is crucial to species conservation as they are listed as near-threatened on the IUCN Red List, and reintroduction could also help restore native ecosystems, the Associated Press reports. "The jaguar lived in these mountains long before Americans did. If done
