It will return true if the int is found in the array, and false if the int is NOT found in the array. Call the checkDuplicates method from both the MegaMillionsLottery constructor, and the getUserPicks() method.
Answers
Answer:
Explanation:
The MegaMillions Lottery class was not provided and neither was the getUserPicks() method. Since they were not found online either, I have created the checkDuplicates method so that it works standalone. Therefore, you can simply call the method from wherever you need by pasting the call line where it needs to be called. A test case has been created in the main method so that you can see the method in action. The output is seen in the attached image below.

if (x == element) {

Discuss the DMA process
Answers
Answer:
Direct memory access (DMA) is a process that allows an input/output (I/O) device to send or receive data directly to or from the main memory, bypassing the CPU to speed up memory operations and this process is managed by a chip known as a DMA controller (DMAC).
Explanation:
A defined portion of memory is used to send data directly from a peripheral to the motherboard without involving the microprocessor, so that the process does not interfere with overall computer operation.
In older computers, four DMA channels were numbered 0, 1, 2 and 3. When the 16-bit industry standard architecture (ISA) expansion bus was introduced, channels 5, 6 and 7 were added.
ISA was a computer bus standard for IBM-compatible computers, allowing a device to initiate transactions (bus mastering) at a quicker speed. The ISA DMA controller has 8 DMA channels, each one of which associated with a 16-bit address and count registers.
ISA has since been replaced by accelerated graphics port (AGP) and peripheral component interconnect (PCI) expansion cards, which are much faster. Each DMA transfers approximately 2 MB of data per second.
A computer's system resource tools are used for communication between hardware and software. The four types of system resources are:
I/O addresses Memory addresses. Interrupt request numbers (IRQ). Direct memory access (DMA) channels.DMA channels are used to communicate data between the peripheral device and the system memory. All four system resources rely on certain lines on a bus. Some lines on the bus are used for IRQs, some for addresses (the I/O addresses and the memory address) and some for DMA channels.
A DMA channel enables a device to transfer data without exposing the CPU to a work overload. Without the DMA channels, the CPU copies every piece of data using a peripheral bus from the I/O device. Using a peripheral bus occupies the CPU during the read/write process and does not allow other work to be performed until the operation is completed.
With DMA, the CPU can process other tasks while data transfer is being performed. The transfer of data is first initiated by the CPU. The data block can be transferred to and from memory by the DMAC in three ways.
In burst mode, the system bus is released only after the data transfer is completed. In cycle stealing mode, during the transfer of data between the DMA channel and I/O device, the system bus is relinquished for a few clock cycles so that the CPU can perform other tasks. When the data transfer is complete, the CPU receives an interrupt request from the DMA controller. In transparent mode, the DMAC can take charge of the system bus only when it is not required by the processor.
However, using a DMA controller might cause cache coherency problems. The data stored in RAM accessed by the DMA controller may not be updated with the correct cache data if the CPU is using external memory.
Solutions include flushing cache lines before starting outgoing DMA transfers, or performing a cache invalidation on incoming DMA transfers when external writes are signaled to the cache controller.
Answer:
See explanation
Explanation:
DMA [tex]\to[/tex] Direct Memory Access.
The peripherals of a computer system are always in need to communicate with the main memory; it is the duty of the DMA to allow these peripherals to transfer data to and from the memory.
The first step is that the processor starts the DMA controller, then the peripheral is prepared to send or receive the data; lastly, the DMA sends signal when the peripheral is ready to carry out its operation.

Answer:
[tex]\tan(x+y) = 3.73[/tex]
Explanation:
The missing part of the question are:
[tex]\sin(x) = \frac{1}{2}[/tex]
[tex]\cos(y) = \frac{\sqrt 2}{2}[/tex]
Required
[tex]\tan(x + y)[/tex]
First, we calculate [tex]\sin(y)[/tex] and [tex]\cos(x)[/tex]
We have:
[tex]\sin^2(x) + \cos^2(x) = 1[/tex]
So:
[tex](1/2)^2 + \cos^2(x) = 1[/tex]
Collect like terms
[tex]\cos^2(x) = 1 - (1/2)^2[/tex]
[tex]\cos^2(x) = 1 - \frac{1}{4}[/tex]
Take LCM
[tex]\cos^2(x) = \frac{4-1}{4}[/tex]
[tex]\cos^2(x) = \frac{3}{4}[/tex]
Square roots of both sides
[tex]\cos(x) = \frac{\sqrt 3}{2}[/tex]
Similarly,
[tex]\sin^2(y) + \cos^2(y) = 1[/tex]
So:
[tex]\sin^2(y)+(\sqrt 2/2)^2 = 1[/tex]
[tex]\sin^2(y)+ (2/4) = 1[/tex]
[tex]\sin^2(y)+1/2 = 1[/tex]
Collect like terms
[tex]\sin^2(y) = 1 - 1/2[/tex]
Take LCM
[tex]\sin^2(y) = \frac{2 -1}{2}[/tex]
[tex]\sin^2(y) = \frac{1}{2}[/tex]
Square roots of both sides
[tex]\sin(y) = \frac{1}{\sqrt2}[/tex]
Rationalize
[tex]\sin(y) = \frac{\sqrt2}{2}[/tex]
So, we have:
[tex]\sin(x) = \frac{1}{2}[/tex] [tex]\cos(x) = \frac{\sqrt 3}{2}[/tex]
[tex]\cos(y) = \frac{\sqrt 2}{2}[/tex] [tex]\sin(y) = \frac{\sqrt2}{2}[/tex]
[tex]\tan(x) = \sin(x) \div \cos(x)[/tex]
[tex]\tan(x) = \frac{1}{2} \div \frac{\sqrt 3}{2}[/tex]
Rewrite as:
[tex]\tan(x) = \frac{1}{2} * \frac{2}{\sqrt 3}[/tex]
[tex]\tan(x) = \frac{1}{\sqrt 3}[/tex]
Rationalize
[tex]\tan(x) = \frac{\sqrt 3}{3}[/tex]
Similarly
[tex]\tan(y) = \sin(y) \div \cos(y)[/tex]
[tex]\tan(y) = \frac{\sqrt 2}{2} \div \frac{\sqrt 2}{2}[/tex]
[tex]\tan(y) = 1[/tex]
Lastly,
[tex]\tan(x + y)= \frac{\tan(x) + \tan(y)}{1 - \tan(x) \cdot \tan(y)}[/tex]
[tex]\tan(x + y)= \frac{\frac{\sqrt3}{3} + 1}{1 - \frac{\sqrt3}{3} \cdot 1}[/tex]
[tex]\tan(x + y)= \frac{\frac{\sqrt3}{3} + 1}{1 - \frac{\sqrt3}{3}}[/tex]
Combine fractions
[tex]\tan(x + y)= \frac{\frac{\sqrt3+3}{3}}{\frac{3 - \sqrt3}{3}}[/tex]
Cancel out 3
[tex]\tan(x + y)= \frac{\sqrt3+3}{3 - \sqrt3}[/tex]
Using a calculator
[tex]\tan(x+y) = 3.73[/tex]

A sinewave has a period (duration of one cycle) of 645 μs. What is the corresponding frequency of this sinewave, in kHz, expressed to 3 significant figures?
please help me figure this out I am so confused
Answers
The corresponding frequency of this sinewave, in kHz, expressed to 3 significant figures is: 155 kHz.
Given the following data:
Period = 645 μsNote: μs represents microseconds.
Conversion:
1 μs = [tex]1[/tex] × [tex]10^{-6}[/tex] seconds
645 μs = [tex]645[/tex] × [tex]10^{-6}[/tex] seconds
To find corresponding frequency of this sinewave, in kHz;
Mathematically, the frequency of a waveform is calculated by using the formula;
[tex]Frequency = \frac{1}{Period}[/tex]
Substituting the value into the formula, we have;
[tex]Frequency = \frac{1}{645\; * \;10^{-6}}[/tex]
Frequency = 1550.39 Hz
Next, we would convert the value of frequency in hertz (Hz) to Kilohertz (kHz);
Conversion:
1 hertz = 0.001 kilohertz
1550.3876 hertz = X kilohertz
Cross-multiplying, we have;
X = [tex]0.001[/tex] × [tex]1550.39[/tex]
X = 155039 kHz
To 3 significant figures;
Frequency = 155 kHz

Usually, applications would have the capability of using either one of these options. But for the sake of the question here are some that usually prefer one method over the other.
