Need Help ASAP!!

Broadcasters use a parabolic microphone on football sidelines to pick up field audio for broadcasting purposes. a certain parabolic microphone has a reflector dish with a diameter of 10 inches and a depth of 2 inches. if the receiver of the microphone is located at the focus of the reflector dish, how far from the vertex should the receiver be positioned?

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

i think that you should ask google for the answer to that problem because if we don't know it google does

table a is wierd
