Answer:
Step-by-step explanation:
Given the equation
A parabola is the locus of points such that the distance to a point the focus equals the distance to a line the directrix.
is the standard equation for an up-down facing parabola with vertex at (h, k), and a focal length |p|.
so
Parabola is symmetric around the y-axis and so the focus lies a distance\ p from the center (0, 0) along the y-axis.
Therefore,
Please check the attached figure too.
An irrational number is a number which cannot be expressed in a ratio of two integers. In rational numbers, both numerator and denominator are whole numbers, where the denominator is not equal to zero. While an irrational number cannot be written in a fraction.
12.64*4=50.56-3.50=47.06
47.06+d
