Answer:
The value of RA is " 9.43".
Step-by-step explanation:
In the given question there is some typing mistake so, the points are:
R =(2, 5)
A= (-3, -3)
Find:
RA= ? where it is a distance (D).
Formula:
put the value in the formula:
15abc² = 5abc · 3c
25a³bc = 5abc · 5a²
GCF(15abc²; 25a³bc) = 5abc
Answer:
the equation of the axis of symmetry is
Step-by-step explanation:
Recall that the equation of the axis of symmetry for a parabola with vertical branches like this one, is an equation of a vertical line that passes through the very vertex of the parabola and divides it into its two symmetric branches. Such vertical line would have therefore an expression of the form: , being that constant the very x-coordinate of the vertex.
So we use for that the fact that the x position of the vertex of a parabola of the general form: , is given by:
which in our case becomes:
Then, the equation of the axis of symmetry for this parabola is:
