I would believe the answer is 9
The answer would be about 93 km in length.
The value of A is 4
<span>4x2 – 20x + 3 = 0
-3 -3
4x2 - 20 x = - 3
Pull out common factor which is 4
4 ( x2 - 5x) = - 3</span>
Answer:
Step-by-step explanation:
W have been given that the vertex of a parabola is at (2, 3) and the point (0, -1) is also on the parabola. We are asked to find the equation of parabola in the form .
We know that vertex form of parabola in form , where (h,k) in vertex of parabola.
Upon substituting coordinates of vertex, we will get:
To find the value of a, we will substitute coordinates of point (0, -1) as:
Therefore, our required equation would be .
