Answer:
Addition
Step-by-step explanation:
You should add 4 and 5 first because of PEMDAS.
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
Since 4+5 is in parentheses it should be done first.
Answer:
3x-x+2=4
Step-by-step explanation:
The domain of f(x)=2^x would be the x values. This would include all values that you can input as x in order to make this problem work. The domain of a function is usually all real numbers. The range of f(x)=2^x would be the y values. This would include all values that would be the output for the y value. An example of this would be if you used 2 as x then the function would read f(x)=2^2. The y would equal 4 which would be included in the range of this function. To find the domain and range of the inverse you would follow the proper steps to get the inverse of the function which would be x=2^y. The domain would be the x values and the range would be the y values. If you put 4 as x which would be your input for the domain you would get 2^4 = 16 for the y which would be the range.
Answer:
965 km per hour
Step-by-step explanation:
The total distance flown was 193km which was flown at constant speed and took 12 minutes. Dividing 193 by 12 gives us the km per minute
193/12 = 16.0833333
but this isn't the correct answer, this is in km per minute, and the question asked for km per hour. Since there are 60 minutes in an hour, multiply the answer by 60 to calculate how far the plane flew per hour.
16.083333333(60) = 965
