Answer:
C) Rotated parallel lines always remain parallel lines.
Step-by-step explanation:Rotated parallel lines remain parallel lines.
Rotation is a rigid transformation, so the lines remain parallel.
The correct answer is option D i.e. 60 The given equation is : 3x^2 + 6x - 2 = 0 The discriminant is given as = {b^2 - 4ac}/2a; where a = 3, b = 6 and c = -2d Thus, D = {6^2 - 4(3)(-2)} or D = {36 + 24} or D = 60
The answer would be 8900
Reason: when you round to 2 significant figures you are trying to reduce the number to 2 digits and the rest will become 0 to indicate a place value
Answer:
40.2
Step-by-step explanation:
law of cosines
x^2=40^2+28^2-2*28*40*cos(70)
put in calculator and square root the answer
40.222.... is approximately 40.2
