We have that
H(t)=-4.9t²<span>+50t + 2
we know that
</span><span>The initial height of the rocket, in meters is for t=0 sec
fot t=0
H(t)=</span>-4.9*0²+50*0 + 2------> H(t)=2 m
the answer is
The initial height of the rocket is 2 m

Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b
where m is the slope and b the y- intercept
If it is a single transformation, it will need to be a homothetic transformation.
None of the points remain at the old place, so it cannot be a scaling problem with respect to one of the existing points.
A homothetic transformation is bacically a scaling problem, with respect to an arbitrary point called the homothetic centre.
The centre, O, if it exists, is along the point joining any original point and the transformed point.
Here, take a pencil (imaginary one if you wish) and join points AA', BB', CC', DD', EE' and you will find that they are concurrent at point O (3,-6).
So O(3,-6) is the centre of homothety.
The scale factor, as usual, is AO/A'O, or BO/B'O... for transformation from X to Y (X is ABCDE), or the reciprocal if it is from Y to X.
