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:

$B' = \alpha \cdot B$

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

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

$B' = (3, -3)$

Evaluate 4!7! divided by 6!8!

faltersainse [42]

! is factorial
it means multipliy all numbers from 1 to that number together
example
1!=1
2!=2*1
3!=3*2*1
etc

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

$\frac{(4!)(7!)}{(6!)(8!)}$
so we can rewrite it as
$\frac{(4!)(7!)}{(4!)(5)(6)(7!)(8)}$ =
$\frac{1}{(5)(6)(8)}$ =
$\frac{1}{240}$
