Perry observes the opposite, parallel walls of a room. In how many lines do the planes containing the walls intersect? Perry observes the opposite, parallel walls of a room.
In how many lines do the planes containing the walls intersect?

a) 0
b)1
c)2
d)3

Answers

"0" would be the number of lines among the choices given in the question that the planes containing the walls will intersect. The correct option among all the options that are given in the question is the first option or option "A". As the walls are parallel to each other, so the planes containing the walls would never intersect.

A polynomial function has a root of –6 with multiplicity 1, a root of –2 with multiplicity 3, a root of 0 with multiplicity 2, and a root of 4 with multiplicity 3. If the function has a positive leading coefficient and is of odd degree, which statement about the graph is true?A)The graph of the function is positive on (–6, –2).
B)The graph of the function is negative on (negative infinity, 0).
C)The graph of the function is positive on (–2, 4).
D)The graph of the function is negative on (4, positive infinity).

Answers

The right answer for the question that is being asked and shown above is that: "B)The graph of the function is negative on (negative infinity, 0)." A polynomial function has a root of –6 with multiplicity 1, a root of –2 with multiplicity 3, a root of 0 with multiplicity 2, and a root of 4 withmultiplicity 3.
