Answer:
15.7 cm
Step-by-step explanation:
Circle x's circumference is 15 * pi = 47.1 cm
Circle y's is 20 * pi = 62.8
The difference is 62.8 - 47.1 = 15.7
(-2)+(-2)+(-2)+(-2)
=-2-2-2-2
= -8

Answer:
B., E.
Step-by-step explanation:
what was the difficulty ? this is just to understand the movement of a thrown rock.
what happens, when you throw a rock through the air ? it will first move up a little bit, reaches a maximum height, and then drops down again.
that is what the graphic shows.
so, can A. be correct ? no. as we move from 0 seconds to the right (time passes) the height of the rock increases first (before decreasing again later on).
can C. be correct ? no, it would mean that the function would look the same on both sides of the x-axis. this is clearly impossible.
can D. be correct ? no, nowhere in the graph is the height (= the functional value, the y to the x) negative.
can F. be correct ? no, we clearly see the maximum height at 1.5 seconds. at 3 seconds the height is actually at its minimum.
