Answer:
•Estimated density = 39.685Pc/mi/en
•Level of service, LOS frequency = LOSC
Explanation:
We are given:
•Freeway current lane width,B = 12ft
• freeway current shoulder width,b = 6ft
• percentage of heavy vehicle, Ptb = 10℅
• peak hour factor, PHF = 0.9
Let's consider,
•Number of lanes N = 4
• flow of traffic V = 7500vph
• percentage of Rv = 0, therefore the freeflow speed in freeway FFS = 70mph
• cars equivalent for recreational purpose Er= 2
•cars to be used for trucks and busses Etb= 2.5
Let's first calculate for the heavy adjustment factor.
We have:
Substituting figures in the equation we have:
= 0.75
Let's now calculate equivalent flow rate of the car using:
= 2777.7 pc/h/en
Calculating for traffic density, we have:
D = 39.685 Pc/mi/en
Using the table for LOS criteria of basic frequency segment, the level of service LOS of frequency is LOSC
Answer and Explanation:
// code
class Main {
public static void main(String[] args) {
/*
*
*
* your code
*
*/
System.out.println(inDogish("aplderogad"));
System.out.println(inXish("aplderogad", "dog"));
}
// returns true if the word is in dog-ish
// returns false if word is not in dog-ish
public static boolean inDogish(String word) {
// first find d
if (dogishHelper(word, 'd')) {
// first find string after d
String temp = word.substring(word.indexOf("d"));
// find o
if (dogishHelper(temp, 'o')) {
// find string after o
temp = temp.substring(temp.indexOf("o"));
// find g
if (dogishHelper(temp, 'g'))
return true;
}
The output is attached below
}
return false;
}
// necessary to implement inDogish recursively
public static boolean dogishHelper(String word, char letter) {
// end of string
if (word.length() == 0)
return false;
// letter found
if (word.charAt(0) == letter)
return true;
// search in next index
return dogishHelper(word.substring(1), letter);
}
// a generalized version of the inDogish method
public static boolean inXish(String word, String x) {
if (x.length() == 0)
return true;
if (word.length() == 0)
return false;
if (word.charAt(0) == x.charAt(0))
return inXish(word.substring(1), x.substring(1));
return inXish(word.substring(1), x.substring(0));
}
}

Answer:
Inductive reactance is denoted by where
from looking at the equation, you can see that as frequency increases, so does the inductive reactance.
