Answer:

1

Step-by-step explanation:

$i^{12}= i^{2} *i^{2} *i^{2} *i^{2} *i^{2} *i^{2}$

Remember that $i^{2}=-1$

Plug it in:

$i^{12}= (-1)^{2} *(-1)^{2} *(-1)^{2} *(-1)^{2} *(-1)^{2} *(-1)^{2}$

$=1*1*1*1*1*1$

$=1$

An assembled product is built by 10 worker who coordinate their task. A total of 100 units will be made. Time records indicate t

Brut [27]

Answer:

a) 86%

b) 2nd unit = 82 hs.

3rd unit = 75 hs

c) 100th unit = 36 hs

Step-by-step explanation:

We can model the learning curve for manufacturing the units as:

$t=aX^b$

where t is the time for the Xth unit, and a and b are parameters that we will calculate from the data,

We know that t(1)=95. Then, we have:

$t(1)=a\cdot 1^b=95\\\\a=95$

And we know that the fourth unit (X=4) take 71 hours to be completed (t(4)=71). Then, we can calculate the other parameter as:

$t(4)=95\cdot4^b=71\\\\4^b=71/95\approx 0.7473\\\\b\cdot ln(4)=ln(0.7473)\\\\b=ln(0.7473)/ln(4)=-0.291/1.386\\\\b=-0.21$

We have the model for the learning curve:

$t=95X^{-0.21}$

The learning rate percentage is calculated from the b parameter:

$b=\dfrac{ln(LRP)}{ln(2)}=-0.21\\\\\\ln(LRP)=-0.21*ln(2)=-0.21*0.693=-0.1455\\\\LRP=e^{-0.1455}=0.86$

The learning rate percentage is 86%.

b) The most likely times required for the 2nd and 3rd units are calculated with the model:

$t(2)=95\cdot2^{-0.21}=95*0.864=82\\\\t(3)=95\cdot3^{-0.21}=95*0.794=75$

c) If we use the model to calculate the time required for the 100th unit, we have:

$t(100)=95\cdot100^{-0.21}=95*0.38=36$

PLEASE HELP ASAP!!!!!!!!!

matrenka [14]

Answer: (-2, 4)

Step-by-step explanation: The right coordinate for point B with 7 units as distance is (-2,4). To arrive at the answer, the distance formula is used. The solution for the problem is:

7= √[(-2-5)² + (4-4)²)

Whats the halfway point from 32 to 16?

irina1246 [14]

The halfway point is 24

• First, add the two numbers: 32 + 16 = 48
• Second, divide the total by 2: 48/2 = 24
