Determine mathematic question. It is used to solve problems in a variety of fields, including science, engineering, and business. The parabola equation in vertex form is \( x = a(y-h)^2 + k \), $$ h = \frac {-b}{(2a)} = \frac {-10} {(2.11)} = \frac {-10}{ 22}$$, $$k = c-\frac{b^2} { (4a)} = 16 \frac {100} {(4.11)}$$, $$ = \frac {704- 100} {44} = \frac {604} {44} = \frac {151}{44}$$, Vertex is \( (\frac{-5}{11}, \frac{151}{11}) \), The focus of x coordinate = \( \frac{-b} {2a} = \frac {-5}{11} \), Focus of y coordinate is = \( c \frac {(b^2 1)} {(4a)} \), $$= 16 \frac {(100 1)} {(4.11)} = \frac {16- 99}{44}$$, $$= \frac{704-99} {44} = \frac{605}{44} => \frac {55}{4}$$, Focus is \( (\frac{-5}{11}, \frac{55}{4}) \), Directrix equation \( y = c \frac {(b^2 + 1)}{(4a)} \), $$ = 16 (100 + 1) / (4.11) = 16- 101/44$$, $$ Axis of Symmetry = -b/ 2a = \frac{-5}{11}$$, for y intercept put x is equal to 0 in equation, now x intercept put y is equal to 0 in equation. Call the focus coordinates (P, Q) and the directrix line Y = R. Step 2. The focus of a parabola can be calculated by knowing the axis of the parabola, and the vertex of the parabola. Well, we can evaluate the axis of symmetry, focus, directrix, vertex, x intercept, y intercept by using the parabola formula in the form of \( x = y^2 + bx + c \). Let ( a, b) be the focus and let y = c be the directrix. Intercepts of Parabola. distance to the directrix, we literally just drop a perpendicular, I guess you could say say, that is, that's going to be the shortest distance to that line, but the distance to the focus, well we see that's at a bit of an angle, and we might have to use The parabola has many important applications, from a parabolic microphone or parabolic antenna to automobile headlight reflectors and the design of ballistic missiles.
