Find s(21) for the sequence s(n) = 5n - 4, n f{1,2,

s(21) = 101.

Step-by-step explanation:

Just substitute n = 21 in the general form:

s(21) = 5(21) - 4

= 105 - 4

= 101. (answer)>

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

translate k to n and reflect across the line containing jk.
