Answer:
C
Step-by-step explanation:
I haven't done this math in years but from what I remember this should be the correct answer.
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.
Any with an odd number of minus signs.
Perhaps the 1st and 4th, if I read it right.
Answer:
We have been given the equation:

And x=10
Substitute the given x in the given equation we get:


On simplification we get:

Required solution is: x= 10 and y=-20
The solution to the system of equation is those points that satisfy the given system of equations.
1 : 100,000
Because there are 100cm in a m and 1000m in a km
100 x 1000 = 100,000
