What is the range of the following relation? {(-1, 1), (-2, 2), (-3, 3), (-4, 4), (-5, 5)}

{-1, -2, -3, -4, -5}
{1, 2, 3, 4, 5}
{-1, -2, -3, -4, -5, 1, 2, 3, 4, 5}

1.8 or

i really dont know

step-by-step explanation:

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west

answer: $13,622.84
