The sequence is 12, 6, 3, 3/2, 3/4 ...
You can obtain any number multiplying the previous number times 1/2.
6 = 12 *(1/2)
3 = 6*(1/2)
3/2 = 3*(1/2)
Answer:
Common ratio =
Step-by-step explanation:
A sequence that progresses geometrically has the first term as 12.
Each number is the previous number divided by 2.
so the sequence will be 12, 6, 3, 1.5...........
Explicit formula of a geometric sequence is given by
Where = nth term of the sequence
a = first term
r = common ratio
and n = number of term
In this sequence common ratio =
=
=
Therefore, common ratio will be

Original price of the telescope is $99.99
Discount: 13%
$99.99 * 13% = 12.9987 or 13
$99.99 - 13 = $86.99 or $87
New selling price is $86.99 rounded up to the nearest unit $87.00
Since there is 13% discount. New price = 100% - 13% = 87% of Original price.
= 87% of 99.99
= 0.87 * 99.99
≈ 86.99
Selling price ≈ $86.99

I don't think the correct y-intercept is offered as one of the choices.
y = 2 (x + 3) (x - 4)
Where the graph crosses
the y-axis, x=0 : y = 2 (0 + 3) (0 - 4)
y = 2 ( 3 ) ( -4 )
y = 2 ( -12 ) = -24

Answer:
Incremental cost of buying = $2.50
Step-by-step explanation:
Cost per unit;
Direct materials = $10.30
Direct labor = $24.30
Overhead = $16.30
Total Overhead cost = 10.30 + 24.30 + 16.30
= $50.90
Where the item is purchased,
Total cost = $46.88 + (40% × 16.30)
= $46.88 + $6.52
= $53.40
Cost difference = $53.40 - $50.90
= $2.50
There is an incremental cost of buying. This amounts to $2.50
