How many planes can contain a line? a.) 0 b.) 1 c.) 2 d.) infinite e.) none of the above

The answer to this is B.

D) infinite

A plane is essentially a flat sheet of paper that doesn't bend or curve. You can also think of the flat ground as a plane. Flat walls and the ceiling are other examples of planes. It is possible to pass infinitely many planes through a single line. The planes will all spin around the line. If you look at a book, the spine can be considered a line while each page is a plane that passes through that line (the pages must be kept straight and not allowed to bend or curve). In mathematical theory, we can have infinitely many page of this "book".

the first one

step-by-step explanation:

just id the test.

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
