Answer:
Step-by-step explanation:
The last step should be: using distributive property by taking out of parentheses the common factor √5
4√5 + 9√5 = √5(4 + 9) = 13√5
Answer:
A
Step-by-step explanation:
The picture below illustrates a hyperbola.
The intersecting plane does not pass through the vertex of a right circular cone (the vertex of the cone is the point where two nappes meet).
As you can see from the diagram, the plane intersects both nappes of a right circular cone.
Hence, correct option is option A: The plane does not pass through the vertex and intersects both nappes of a right circular cone.
84.10 because the denominator 10 x the whole number 8 + the numerator 4,
so 10x8+4=84 and the denominator is behind the 84 and the decimal is between the 84 and 10 so the answer is 84.10.
