Colt1911 [192]

Answer:

The change in available disk space is −6% per episode

Step-by-step explanation:

Given that :

Available disk space changed from 81% to 9% after recording 12 episodes of a show

Each episode requires the same amount of disk space

Change in disk space =

Final % = 9%

Initial percentage = 81%

Change = final value - initial value :

(9 - 81)% = -72%

72% reduction in disk space

Space taken up per episode :

Reduction in space / number of episodes

= -72% / 12

=- 6%

What is the rule for a counterclockwise rotation about the origin of 210°
Phoenix [80]

Answer:

  (x, y) ⇒ (-x√3/2 +y/2, -x/2 -y√3/2)

Step-by-step explanation:

The rule for CCW rotation through an angle α is ...

  (x, y) ⇒ (x·cos(α) -y·sin(α), x·sin(α) +y·cos(α))

So, for α = 210°, the rule becomes ...

  (x, y) ⇒ (-x√3/2 +y/2, -x/2 -y√3/2)

Harlamova29_29 [7]

Answer:

$49.572

Step-by-step explanation:

Given that :

Cost per disc = $18

Number of disc purchased = 3

Discount received = 15%

Sales tax = 8%

Original cost : cost per dic * number purchased

Original cost = $18 * 3 = $54

Discounted price = (100 - 15)% * $54

Discounted price = $45.9

Sales tax :

(100 + 8)% of $45.9

108% * $45.9

= $49.572

Total price = $49.572
