Answer:
-2.6
Step-by-step explanation:
10.9 + (-15.6) becomes 10.9 - 15.6 which equals -4.7. The last step is to add the 2.1 to the -4.7: -4.7 + 2.1 = -2.6
Therefore the answer is -2.6

C = 2 * pi * r
C = 2 * pi * 18
C = 36pi or C
Answer:
see below
Step-by-step explanation:
g(x) = 3 − x^2
(a)g(30) = 3 - 30^2 = 3 - 900 = -897
(b)g(3)= 3- 3^2 = 3-9 = -6
(c)g(−1) = 3 - (-1)^2 = 3 - 1 = 2
(d)g(0.5) = 3 - (.5)^2 = 3 - .25 = 2.75
2 lines are skew if they are neither parallel, nor intersecting.
If 2 lines are parallel or intersecting, they form a plane, so they are coplanar. So "skew" is the opposite or complement of "coplanar".
i) a and b: are both on M so coplanar, not skew
ii) b is in M, c is in N and they have no common point, so skew. (if they had a common point that would be a point in the line d of intersections of planes M and N, but they dont meet at such a point)
iii) b and e: are both on M so coplanar, not skew
iv) e and c : skew, same argument as ii.
v) a and e : are both on M so coplanar, not skew
vi) a and c: a is in M, c is in N. If they met, they would met at a point on line d, the only set of points common to planes M and N, but they dont. so skew
