Answer:
y = 41°
Step-by-step explanation:
∡ y and 139° are adjacent angles and sum to 180° , that is
∠ 1 + 139° = 180° ( subtract 139° from both sides )
∠ 1 = 41°
Answer:
a. Juan
b. J(t) = A(t) at t = 7 minutes
c. J(t) > A(t) for the interval 0 ≤ t ≤ 7
Step-by-step explanation:
a. From the graph, Juan completes the 4-mile bike race in 13 minutes while Antonio completes the 4-mile bike race in 15 minutes, therefore, Juan completes the distance first and wins the race
b. From the graph, the line of the graph of the functions J(t) and A(t) are equal at the time t = 7 minutes
Therefore;
J(t) = A(t) at t = 7 minutes
c. The value of the function, and the line of the graph of the function, J(t) is larger than and above the value and the line of the graph of the function A(t) for the interval 0 ≤ t ≤ 7
