D is m<5+m<6 Please answer im not very good with this math

damaskus [11]

Answer:

A. m∠2 + m∠3

Step-by-step explanation:

The exterior angle theorem states that the exterior angle formed when you extend the side of a triangle is equal to the sum of its non-adjacent angles.

So m∠4's non-adjacent angles are 2 and 3 NOT 1. Therefore, the measure of ∠4 = m∠2 + m∠3.

Hope this helps!

A firm that stocks lightbulbs gathers the following information: Demand = 19,500 units per year, Ordering cost = $25 per order,

vredina [299]

Answer:

Step-by-step explanation:

Demand = 19,500 units per year (D)

Ordering cost = $25 per order (O)

Holding cost = $4 per unit per year (C)

a) $EOQ=\sqrt{ \frac{2\times D\times O}{C}}$

$EOQ=\sqrt{ \frac{2\times 19,500\times 25}{4}}$

= $\sqrt{\frac{975000}{4}}$

= $\sqrt{243,750}$

= 493.71044 ≈ 494

b) Annual holding cost = $4\times(\frac{Q}{2})$

= $4\times(\frac{494}{2})$

= 4 × 247

= 988

c) Annual ordering cost = $O\times(\frac{D}{Q} )$

= $25\times(\frac{19,500}{494} )$

= 25 × 39.47

= 986.75

AOQ = 494

Annual holding cost = 988

Annual ordering cost = 986.75

During a scuba dive, Lainey descended to a point 23 feet below the ocean surface. She continued her

abruzzese [7]

t (23) ≤ 97 - 23

The minus 23 at the back represents the feet she already descended before what the question wants us to calculate

≤ is used instead of < because it states more than, not "equal or more than" (meaning 97 sharp is fine)

Determine the open intervals on which the graph of f(x) = x - 4cos x is concave upward or concave downward

bazaltina [42]

The graph of the function $f(x)$ is

concave upward, when $f''(x)>0;$
concave downward, when $f''(x)$

Find $f''(x):$

$f'(x)=(x-4\cos x)'=1+4\sin x;$

$f''(x)=4\cos x.$

Now:

1. when $4\cos x>0,$ the graph of the function is concave upward and this is for

$x\in \left(-\dfrac{\pi}{2}+2\pi k,\dfrac{\pi}{2}+2\pi k\right), \text{ where } k\in Z.$

2. when $4\cos x$ the graph of the function is concave downward and this is for

$x\in \left(\dfrac{\pi}{2}+2\pi k,\dfrac{3\pi}{2}+2\pi k\right), \text{ where } k\in Z.$
