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.
Answer:
i believe the answer is $0.22 per pound.
Step-by-step explanation:
Increase = 14
Total =50
Percentage increase = 14/50 x 100 = 28%
Perimeter of a rectangle: 2(l+w)
Let width be 'x'
Length is 3 meters more than twice 'x'
Length= 2x+3.
L= x
W = 2x+3
Formula =
2(x+2x+3)
2(3x+3)
6x+6.
6(x+1)
Answer:
1 and a half inches long
Because that 3 divided by 2 is 1.5.
