PLEASE HELP I WILL GIVE BRAINLIEST! (NO LINKS) Carlos and Clyde challenged each other to a 140 mile motorcycle race (70 miles going west and then 70 miles east, returning to the starting position). Carlos traveled at a constant speed of 60 mph going west but returned at a constant speed of only 40 mph. Clyde traveled at a constant speed of 50 mph in each direction.

1.) How much time did it take each participant to finish the race?
2.) Who won?

f(x)=2/3x-8, which give g(x) the greatest value.

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

false

inverse variation is not exponential
