Lesechka [4]

Answer:

Produce only Product B.

Step-by-step explanation:

The contribution margin per machine hour for product A is ...

($16 -$6)/(5 hour) = $2 per hour

The contribution margin per machine hour for product B is ...

($12 -$5)/(3 hour) ≈ $2.33 per hour

The company should produce the maximum possible number of the product that contributes the most per machine hour: Product B.

Find the distance between (2,7) and (-6,-2)

stepladder [879]

Answer: $\sqrt{145}$

Step-by-step explanation:

1. use the distance formula!

$distance = \sqrt{(x_{2} - x_{1})^{2} +{(y_{2} - y_{1})}^2$

2. then using the distance formula with (2, 7) and (-6, -2) you get...

$distance= \sqrt{2 -(-6)^2 +(7 - (-2)^2}$

$distance= \sqrt{8^2 +9^2}$

$distance= \sqrt{64 +81}$

$distance= \sqrt{145}$

$\sqrt{145}$ is the simplest radical form

Which function is odd? Check all that apply.

kvasek [131]

$The\ function\ is\ odd\ if\ f(-x)=-f(x)\\\\We\ know:\\\sin x;\ \tan x\ and\ \cot x\ are\ odds.\\\cos x\ is\ even\ /\cos(-x)=\cos x/\\--------------------\\\\A.\ y=\sec x\\\\\sec(-x)=\dfrac{1}{\cos(-x)}=\dfrac{1}{\cos x}=\sec x-\fbox {NO}\\\\B.\ y=\sin x-\fbox{YES}\\\\C.\ y=\cot x\\\\\cot(-x)=\dfrac{\cos(-x)}{\sin(-x)}=\dfrac{\cos x}{-\sin x}=-\dfrac{\cos x}{\sin x}=-\cot x-\fbox{YES}\\\\D.\ y=\csc x\\\\\csc(-x)=\dfrac{1}{\sin(-x)}=\dfrac{1}{-\sin x}=-\dfrac{1}{\sin x}=-\csc x-\fbox{YES}$
