You would have no trouble at all if the problem said "11 cows - 8 cows",
or "11 books - 8 books", or "11 cats - 8 cats", or "11 footballs - 8 footballs".
So why does it scare you when the items being counted are 'm's ?
Oh ! Here's another beauty: 11 M&Ms - 8 M&Ms = ?
192* 6/6+2= 144(do )
192*2/6+2=48( do not do )
Range is directly correlated by the K of the function. since K is 1, the answer is B
Answer:
81 meters.
Step-by-step explanation:
The height (in meters), h(x) of a hovercraft x seconds after takeoff, is modeled by:

We are to determine its height at the time of takeoff.
Now, at the time of takeoff, x=0.
We substitute x=0 to solve for h.

The height of the hovercraft at takeoff is 81 meters.
