Answer:
What is the difference between entering a formula and entering data ??
16 rounded to the tens place = 20
6216 rounded to the thousands place = 6000
6000/20 = 300 <==
No; a domain value has two range values.
x = -2 then y = 1 and 2
they would form a vertical line, which tells us that it's not a function
We know that a triangle has three sides, all the same length (its equilateral, after all)
The equation to find the length of each side is
Perimeter divided by 3
or in this case
48.6 divided by 3=16.2cm (don't forget the unit)
Hope that helps :)
