No, not a function. At 70 and 71 we have two values; a function can only have one y value for any x value. That's not true here. It's sometimes called <em>failing the vertical line test.</em>
C. Equilateral triangles I believe
1. Know that: (1) in 28 miles, there are 147,840 ft because 28*5280, (2) radius is 7/6 because that is (2 1/3)/2, (3) C=2(pi)(7/6) or pi*7:3
2. To find revolutions per minute, you take 147,840 and divide it by the circumference to get revolutions per hour, which is about 20168.11439. Then, divide this by 60 to find revolutions per minute: 336.1352398 revolutions/min.
3. Then, to find the angular measure in radians you take the revolutions per minute and multiply it by 2pi.
Answer: not very sure but i think that may be 5
