liberstina [14]4 years ago

Answer:

-1

Explanation:

The given equation can be written as

-3x +y^2 +2y +1=b+1

-3x +(y+1)^2=b+1

(-3x-b)+ (y+1)^2=1

This is to be compared with (x-a)^2 + (y-b)^2=c^2

where (a,b) is the center, and c is the radius of the circle.

Thus, we get y=-1, and this is our answer.

Explain the developments RAM since it was created in 1968 til today.
xenn [34]

Answer:

From DRAM to DDR4

Explanation:

RAM stands for <em>Random Access Memory.</em> In 1968, Mr. Robert Dennard at IBM's Watson Research obtained the patent for the one-transistor cell that will eventually substitute the old magnetic core memory allocated in computers of the time. By 1969 Intel released the TTL bipolar 64-bit SRAM (Static Random-Access Memory) as well as the ROM "Read Only Memory"; also in 1969 it evolved into "<em>Phase - change memory - PRAM - </em>". However this evolution was not commercialized, Samsung expressed its interest in developing it. In 1970 the first DRAM product was commercially available; it was developed by Intel. In 1971 it was patented EPROM; in 1978 George Perlegos developed EEPROM.

By 1983 a nice breakthrough happened with the invention of SIMM by Wang Labs. In 1993 Samsung came up with KM48SL2000 synchronous DRAM (SDRAM), this variation soon turned into an inductry standard.

In 1996 DDR began a revolution in the memory sector, then in 1999 RDRAM. Both DDR2 SDRAM. DDRR3 and XDR DRAM were commercialized. Finally in 2007 and 2014 the developments of DDR3 and DDR4 were available for the general public.

Describe the user interface in other high-technology devices commonly found in the home or office, such as a smartphone, HD tele
Vadim26 [7]

Answer:

Explanation:

Different technologies use different user interface designs in order to make the user experience as easy and intuitive as possible. This varies drastically from one device to another because of the capabilities and size of each device. If we take a fitness/smart watch into consideration, this device does not use pop up menus or side scrolling menus but instead uses large full screen menus where each option nearly fills the entire screen. That is done because the smart watch screens are very small and making everything full screen makes reading and swiping through options that much easier for the user. If the user interface were the same as in a television or smartphone it would be impossible to navigate through the different options on such a tiny screen.
