1. Two hydroacoustic stations are being established to detect explosions under water or in the atmosphere at
low altitude. Station A is located at (30, – 280) and station B at (70, – 320).
E
E
A new hydroacoustic station is planned to be established on a line perpendicular to the line
joining these stations. Write an equation in slope-intercept form of the perpendicular line
containing station A

answer: '

the distance between points l and m

step-by-step explanation:

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

answer: youre the sweetest thing for that
