the axis of symmetry is x=2
Answer:
4•8 feet
Step-by-step explanation:
Distance= first floor × second ÷ escalator
Distance= 12feet × 12feet ÷ 30 feet
= 12×12÷30
= 4•8 feet
Answer:
228
Step-by-step explanation:
Rule: second differences are 2.
Selection C is appropriate.
_____
First differences are the sequence of differences of the given numbers:
.. 3 -8 = -5
.. 0 -3 = -3
.. -1 -0 = -1
.. 0 -(-1) = 1
Second differences are the sequence of differences of these:
.. -3 -(-5) = 2
.. -1 -(-3) = 2
.. 1 -(-1) = 2
All of these are 2, so the sequence can be described by a *second* order polynomial (because *second* differences are a non-zero constant).
