Answer:
13
Step-by-step explanation:
J get answer on this way:
1 inches =2,54 centimeters,
5 inches=12,7 centimeters,
50 inches=127 centimeters,
average= 12,7/4+127/4+5/4+50/40=48,67 centimeters
They get ten times smaller, so you could say a number is getting divided by ten or the decimal point is moving to the left one place value.
To the nearest ones, it's 726.
To the nearest tens, it's 730.
To the nearest hundreds, it's 700.
To the nearest thousands, it's 1000.
Answer:
Option "B" as per the list of possible answers
Step-by-step explanation:
Notice that the parabola has a minimum at the point (2, 1), therefore first look at which of the options gives you 
. You would be able then the discard the last two functions listed (they render "-1" (not 1) for x = 2.
Now to decide between the first and the second option, notice that the first option has a negative coefficient (-0.2) multiplying the perfect square 
which means that the branches of such parabolic function would be pointing down. So you discard the first option, and now the only one left is the second option:
which you can check briefly by evaluating a couple of easy points (like what values you get for x = 0, and at x = 4, and confirm it is the correct option.
