Answer:

while (userNum >=0) {...}

Explanation:

In a while loop, the loop is executed until the condition is false.

Since the loop will execute while the user enters a number greater than or equal to 0 (and that number is declared as userNum), we need to check if userNum is greater than or equal to 0.

Prove that any amount of postage greater than or equal to 64 cents can be obtained using only 5-cent and 17-cent stamps?

elixir [45]

Let P(n) be "a postage of n cents can be formed using 5-cent and 17-cent stamps if n is greater than 63".Basis step: P(64) is true since 64 cents postage can be formed with one 5-cent and one 17-cent stamp.Inductive step: Assume that P(n) is true, that is, postage of n cents can be formed using 5-cent and 17-cent stamps. We will show how to form postage of n + 1 cents. By the inductive hypothesis postage of n cents can be formed using 5-cent and 17-cent stamps. If this included a 17-cent stamp, replace this 17-cent stamp with two 5-cent stamps to obtain n + 1 cents postage. Otherwise, only 5-cent stamps were used and n 65. Hence there are at least three 5-cent stamps forming n cents. Remove three of these 5-cent stamps and replace them with two 17-cent stamps to obtain n + 1 cents postage.Hence P(n + 1) is true.

Help me understand why it does not loop correctly and how to make the converter a continious loop? What am I doing wrong and how

Aleksandr-060686 [28]

Answer:

The control loop responds to

the overcharged VOUT with a skipped pulse to

regulate VOUT to the correct DC voltage. Other

converters may respond differently when the

minimum on-time is violated. For example, the

fSW may begin to decrease or VOUT may become

regulated to a higher voltage

Explanation:

If you are trying to make a loop run a certain number of time in Python, then...

To repeat something a certain number of times, you may:

1. Use range or xrange for i in range(n): # do something here.

2. Use while i = 0 while i < n: # do something here i += 1.

3. If the loop variable i is irrelevant, you may use _ instead for _ in range(n): # do something here _ = 0 while _ < n # do something here _ += 1.
