The time required for a race car to complete a 400 mile race is inversely proportional to the average speed that the car maintains. Express the relationship between race time and average speed in two equivalent forms.
Answer:
A.
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
We know that
cos A = adjacent / hypotenuse
sin A = opposite / hypotenuse
Therefore, sin A / cos A =
(opposite / hypotenuse) / (adjacent / hypotenuse)
= (opposite/hypotenuse) * (hypotenuse / adjacent)
= opposite / adjacent
= tan A
Therefore, tan A = sin A / cos A = y/x
