The answer would be f(x)=3.9n+15.85 since every floor is 3.9 meters high you need to multiply 3.9 by the number of floors which in this case would be n. Then you add the height of the antenna because it is included in the measurement. Using the order of operations you would multiply from right to left first which would give you the height of the building without the antenna, then you would add the 15.85 which would give you the total height of the building including the antenna if you would know how many floors there are.
The answer is a(-9,0)
Because I know lol
Answer: 42650
Step-by-step explanation:
The tens place is behind the ones place.
The number in the tens place in 42653 is 5.
So to round to the nearest tens you have to change three to 0 because if the number in the ones place is 5 or more, then the number in the tens place would be 1 higher than it used to be while the number in the ones place turns to 0.
However if the number in the ones place is less than 5, then that's the only thing that changes, the ones place would change into a '0.'
Hope that helped!
