An architect was asked to build a special staircase in a new building. The staircase
will be built like a helix that rotates around the outside of a cylindrical waterfall.
Because it is a helix, the beginning of the staircase begins at a point directly above
the position where the staircase ends at the bottom base of the column. Describe
how to find the length of the staircase if the cylinder it surrounds is 30 m in height ar
has a radius of 12 m.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

this doesn't make sense lol

18.8cm hope i at all

step-by-step explanation:

see below

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right
