Answer:

Give at least one reason why it's useful to learn how to solve and program solutions with a limited set of commands. So that when there is more commands we know how to use the ones we have. parameters help generalize the solution to a specific problem. how are functions with parameters an example of abstraction?

An object completes one round of circle of radius 7m in 20 sec. Distance travelled after 10 sec is?

Ivanshal [37]

Answer:

$distance \: travelled \: = 2\pi \\ \\ 44cm \: \: \: \: \\ speed \: = \frac{44}{2.2} \ \\ distance \: travelled \: in \: los = 10 \times 2.2 = 22cm \\ \\ total \: distance = 44 + 22 = 66metres$

Express the following binary numbers in hexadecimal. (a) %100011100101 (b) %1011001111 (show work)

Lapatulllka [165]

Answer:

$(100011100101)_{2} = (8E5)_{16} = %8E5$

$(1011001111) = (2CF)_{16} = %2CF$

Explanation:

Binary and hexadecimal values have the following pair equivalences.

$(0000)_{2} = (0)_{16}$

$(0001)_{2} = (1)_{16}$

$(0010)_{2} = (2)_{16}$

$(0011)_{2} = (3)_{16}$

$(0100)_{2} = (4)_{16}$

$(0101)_{2} = (5)_{16}$

$(0110)_{2} = (6)_{16}$

$(0111)_{2} = (7)_{16}$

$(1000)_{2} = (8)_{16}$

$(1001)_{2} = (9)_{16}$

$(1010)_{2} = (A)_{16}$

$(1011)_{2} = (B)_{16}$

$(1100)_{2} = (C)_{16}$

$(1101)_{2} = (D)_{16}$

$(1110)_{2} = (E)_{16}$

$(1111)_{2} = (F)_{16}$

We convert from binary to hexadecimal selecting groups of 4 binary from the binary code, from the least significant bits(at the right) to the most significant bits(at the left). The conversion is an hexadecimal "string" from the last group you converted to the first. So:

(a) %100011100101

$(0101)_{2} = (5)_{16}$

$(1110)_{2} = (E)_{16}$

$(1000)_{2} = (8)_{16}$

$(100011100101)_{2} = (8E5)_{16}$

(b) %1011001111

$(1111)_{2} = F_{16}$

$(1100)_{2} = C_{16}$

$(10)_{2} = (0010)_{2} = 2_{16}$

$(1011001111) = (2CF)_{16}$

Given the class 'ReadOnly' with the following behavior: A (protected) integer instance variable named 'val'. A constructor that

Dafna1 [17]

Answer:

I believe you want a subclass so here it is!

public class ReadWrite extends ReadOnly {

public ReadWrite(int initialValue){

super(initialValue);

}

private boolean modified = false;

public void setVal(int x) {

val = x;

modified = true;

}

public boolean isDirty() {

return modified;

}

Explanation:

I might be wrong, just check through it in case

Hope this helped
