Note the graph of an athletes performance after finishing a triathlon. The x-axis measures time in hours, and the y axis measure
s distance in kilometers. First she swam, then biked, and then she finished the race with a run. The data states she ran four times as fast as she swam and she biked twice as fast and she ran. Based on the graph, chose the statement below that is false.
A) the steeper the segment, the faster the athlete is traveling along the course
B) the athlete finished the course in under eight hours
C) the athlete spent equal amounts of time biking and running
D) the athlete spent twice as much time biking compared to swimming

Answer:
cos Θ =
Step-by-step explanation:
Given the angle passes through (4, 5 ) then the right triangle with sides 4 and 5 has hypotenuse h given by
h² = 4² + 5² = 16 + 25 = 41 ( take the square root of both sides )
h =
In relation to Θ, 4 is adjacent and 5 is opposite, thus
cos Θ = =
