Answer:
69.54
Explanation:
A power ratio of 9000000:1 corresponds to 69.54 dB.
The calculation is presented below:
Formula for calculating Power ratio (db) = 10 * log [P(out)/P(in)]
Since the given ratio is 9000000:1, substituting in the formula gives us 10 * log (9000000/1)
Note that log 9000000 = 6.954
Therefore, 10 * log (9000000/1) = 69.54
Hence the required power ratio in db is 69.54 db.
Answer:
The answer to this question can be given as:
Statement:
isQuadrilateral = (numberOfSides == 4) ? 1 : 0;
//check condition using ternary operator.
Explanation:
we know that both(Quadrilateral, numberOfSides) is already declared in the program. So the statement for check condition is (isQuadrilateral = (numberOfSides == 4) ? 1 : 0;). To check this condition we use the ternary operator. In this operator, we also check another condition. The syntax of ternary operator (condition ? value_if_true : value_if_false).In this statement on the lift side we use the variable for check condition and right side we check condition if the value is true it prints 1 else it will print 0.
Answer:
The correct option is B) Task has a due date instead of a specific time and place.
Explanation:
Task can be defined as any piece of work which is to be done in a specific, given period of time. On the other hand, appointment can be described as assigning a specific time to some one or scheduling a certain meet- up with someone. An appointment will have a specific time and place whereas a task will have a given time, not a specific time. Hence, the correct option is B.
