Answer:

  • an = 5 + 10(n -1)
  • a7 = 65

Step-by-step explanation:

The explicit formula for the n-th term of an arithmetic sequence is ...

  an = a1 + d(n -1)

where a1 is the first term and d is the common difference.

The sequence of seat counts has a1=5 and d=10, so the explicit formula is ...

  an = 5 +10(n -1)

___

The 7th term is ...

  a7 = 5 +10(7 -1) = 65

Point B has coordinate B(1, –1). What is the coordinate of B' under a scale factor of 3?
Zarrin [17]

Answer:

The coordinate B' is B' = (3, -3).

Step-by-step explanation:

The new coordinate is computed by applying the scale factor with respect to origin:

B' = \alpha \cdot B

B' = 3\cdot (1,-1)

B' = (3\cdot 1, 3 \cdot (-1))

B' = (3, -3)

etc

some things to note
7!*8=8!
4!*5*6=6!


\frac{(4!)(7!)}{(6!)(8!)}
so we can rewrite it as

\frac{1}{(5)(6)(8)}=
\frac{1}{240}
