Derive the equation of the parabola with a focus at (β7, 5) and a directrix of y = β11.
f(x) = one thirty second(x + 7)2 β 3
f(x) = βone thirty second(x + 7)2 β 3
f(x) = βone thirty second(x β 7)2 β 3
f(x) = one thirty second(x β 7)2 β 3

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 ft further and marks point d. she turns 90Β° and walks until her location, point a, and point c are collinear. she marks point e at this location, as shown. (a) can kayla conclude that Ξ΄ and Ξ΄ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?
