The parabola graphed below represents a side view of a parabolic microphone dish. the directrix is drawn in as well. the end of the microphone is placed on a feedhorn that will need to be placed at the focus of the parabola to pick up the sound. the scale of the graph is in inches.

based on the graph, the engineers should make the feedhorn inches long.

the answer is c hope it

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
