A publisher estimates the annual demand for a book to be 8000 copies, and built a warehouse to accommodate at most 8000 copies.

Illusion [34]

Answer: $1000

Step-by-step explanation:

Annual demand (D) = 8000

Cost per order (S) = $1000

Cost per unit to print = $8 per book

Storage cost = $2 per book per year

The minimum total cost can be found thus :

√(2 × D × S) / storage cost * cost per unit

√(2 × 8000 × 1000) / (2 * 8)

√ (16,000,000 / 16

√ (1,000,000

= 1000

Hence , minimum total cost $1000

If cos theta=-2/3, which of the following are possible (Help asap)

alexgriva [62]

Answer:

The correct option is B) $sin\theta=\frac{\sqrt{5}}{3}$ and $tan\theta=\frac{\sqrt{5}}{2}$

Step-by-step explanation:

given $cos\theta=-\frac{2}{3}$

Since, $cos\theta=\frac{base}{hypoteneous}$

it means prependicular of right angled triangle can be calculated by pythagoras theorem as:

base² + prependicular² = hypoteneous²

2² + prependicular² = 3²

4 + prependicular² = 9

prependicular² = 9 - 4

prependicular² = 5

prependicular = √5

Since, $sin\theta=\frac{prependicular}{hypoteneous}$

$sin\theta=\frac{\sqrt{5}}{3}$

Since, $tan\theta=\frac{prependicular}{base}$

$tan\theta=\frac{\sqrt{5}}{2}$

Hence, the correct option is B) $sin\theta=\frac{\sqrt{5}}{3}$ and $tan\theta=\frac{\sqrt{5}}{2}$
