Linearity is proved by showing it can be written with constants, while time-invariance is proved by showing the system response is independent of time. Non-linearity is proved by showing the cosine function is not linear and time-variance is proved by showing coefficients change with time.
(a) System (a) is linear because it can be written in the form y[n] = a1x[n] + a2x[n-1] + a3y[n-5], where a1, a2, and a3 are constants. It is also time-invariant since the output at any time point is independent of the time at which the input is applied. This can be proved by showing that the system response is the same for any input shifted in time by a constant value.
(b) System (b) is non-linear as it contains the cosine function, which is not a linear operator. It is also time-varying since the coefficients for the output y[n-2] and y[n] depend on the time index n. This can be seen from the fact that the coefficients for cos (pi/6 n) change for each value of n.

gasoline volatility is being discussed. technician a says gasoline blended for summer use is more volatile than winter gasoline. technician b says in high altitude areas, fuels must be blended to have higher volatility.
Both technician a and technician b are correct that gasoline volatility is being discussed and it have higher volatility.
This is because in the summer, gasoline must be able to evaporate quickly in order to create the proper air/fuel mixture for combustion. In contrast, winter gasoline is blended to be less volatile to prevent vapor lock, which occurs when gasoline vaporizes too quickly and creates air pockets in the fuel line. The lower air pressure at high altitudes can cause gasoline to vaporize more slowly, which can result in poor engine performance. By blending fuels with a higher volatility, gasoline is able to vaporize more quickly, ensuring proper combustion in high altitude environments.

The tension in cable DA is The tension in cable DB is The tension in cable DC is KN. KN. KN.
The tension in each cable is determined by applying an upward force of 45kN at point D. The tension in cable DA is 15kN, in cable DB is 30kN, and in cable DC is 0kN.
The tension in each cable is determined by calculating the force of the upward force of 45kN applied at point D. The force is then distributed among the three cables, with the force being inversely proportional to the length of the cable. Cable DA has a length of 3m, DB is 0.75m and DC is 1.5m. Therefore, the tension in cable DA is 15kN, in cable DB is 30kN, and in cable DC is 0kN. This is because the force is inversely proportional to the length of the cable, meaning that the longer the cable, the less tension it has. Thus, since cable DA is the longest, it has the least amount of tension. Similarly, cable DB is the shortest, thus it has the highest amount of tension. Cable DC is in the middle and has no tension.

The Big-O notation is a mathematical representation used to analyze the efficiency of algorithms in computer science. In this case, we are asked to rank five expressions based on their asymptotic growth rates. The expression with the smallest growth rate is ranked first, while the expression with the largest growth rate is ranked last.
The first expression is lgn, which has the smallest growth rate among the given expressions, making it the first ranked. The second expression, 100n + lgn, has a linear growth rate that dominates the logarithmic growth rate, ranking it second. The third expressions is 2^9999 lgn, which grows faster than lgn but slower than 3n lgn, ranking it third. The fourth expressions is 3n lgn, which has a growth rate of n multiplied by logarithmic, ranking it fourth. Lastly, n! + lgn has the largest growth rate and is ranked fifth.
It's important to understand Big-O notation because it helps us compare the efficiency of algorithms and determine the scalability of a program. By analyzing the asymptotic growth rate, we can determine the best algorithm to use for a particular task, ensuring optimal program efficiency.

Complete the combineNames method to return a new String array that is composed of the first name and last name of each of the parameters.This may be confusing so look at the example:first_names = {"bob","joe"}last_names = {"jones","smith"}returns a new String array with {"bob jones", "joe smith"}class Main{public static String[] combineNames(String[] first_names, String[] last_names){}public static void main(String[] args){//feel free to test code here}}
The combineNames method combines two arrays of names into one.
String[] combinedNames = new String[first_names.length];
for (int i = 0; i < first_names.length; i++)
{
combinedNames[i] = first_names[i] + " " + last_names[i];
}
return combinedNames;
The combineNames method takes two String arrays, one containing first names and one containing last names, and combines them into a single String array. To do this, a new String array is created with the same length as the first_names array. Then, a for loop is used to iterate over each element in the first_names array and combine it with the corresponding element in the last_names array. The combined names are then added to the combinedNames array, and when the loop finishes, the combinedNames array is returned. This method allows for easy manipulation of the two arrays and allows for the creation of a new array that contains both first names and last names.

an abnormally high engine oil temperature indication may be caused by
Extremely high engine temperatures can be the result of poor cooling caused by an improper fuel grade, a too lean mixture, a lack of lubrication, or a lack of airflow over the engine.
What function does engine oil serve?
To prevent friction and needless power loss, engine oil has to lubricate every part of the engine.
Since it will burn gasoline more efficiently, a well-lubricated engine will operate more smoothly. However, taking care lubrication is only one of many tasks.
The surfaces and parts that are sensitive to friction are protected when friction diminishes. To increase the parts' lifetime, wear is minimised.
Additionally, corrosion is prevented from developing on the surface of engine parts by a proper engine oil.
