A whole number greater then 10 but less then 15 would be 12
Answer: Choice C)
Stretched vertically, flipped over x axis, shifted 7 units down
------------------------------------------------
Explanation:
Going from y = x^3 to y = 2x^3 means the graph is pulled vertically so that each (x,y) point has the y coordinate that is doubled. Example: (1,1) turns into (1,2). If this applies to all the points, then the graph is stretched vertically by a factor of 2
Going from y = 2x^3 to y = -2x^3 flips the graph over the y axis. For example, the point (1,2) flips to (1,-2). The x coordinate stays the same with the y coordinate flipping in sign.
The last transformation is the shifting 7 units down which is taken care of by the "-7" tacked at the end. Essentially we subtract 7 from each y coordinate. Example: (1,-2) becomes (1,-9)
Answer:
38) Angle 2 = 32°; angle 1 = 32°; angle 3 = 110°
39) Angle 3 = 81°; Angle 2 = 28°; angle 1 = 71°
Step-by-step explanation:
38) angle 2 = 180 - (110 + 38)
This is because sum of angles in a triangle is equal to 180°. Thus;
Angle 2 = 32°
Angle 1 = 38° due to the postulate that alternate interior angles are equal
Angle 3 = 110° due to corresponding angles postulate
39) Angle 3 = 81° due to the postulate that alternate interior angles are equal
Angle 2 = 28° due to the postulate that alternate interior angles are equal
Angle 1 = 180 - (81 + 28) = 71° due to the fact that angles in a triangle sum up to 180°
