Answer:
3 times
Explanation:
When the dough is folded, it increases by a constant factor. We can model the growth of the thickness using the exponential growth model
![T(n)=T_0(1+r)^n](https://tex.z-dn.net/?f=T%28n%29%3DT_0%281%2Br%29%5En)
Where:
Initial thickness,
= 2mm
Growth factor, r =8%=0.08
We want to find the smallest number of times Soon Yi will have to roll and fold the dough so that the resulting dough is at least 2.5mm.
i.e When ![T(n)\geq 2.5$ mm](https://tex.z-dn.net/?f=T%28n%29%5Cgeq%202.5%24%20mm)
![2(1+0.08)^n\geq 2.5\\2(1.08)^n\geq 2.5\\$Divide both sides by 2$\\\dfrac{2(1.08)^n}{2}\geq \dfrac{2.5}{2}\\\\1.08^n\geq 1.25\\\\$Change to logarithm form\\n \geq \log_{1.08}1.25\\\\n\geq \dfrac{\log 1.25}{\log 1.08} \\\\n\geq 2.9](https://tex.z-dn.net/?f=2%281%2B0.08%29%5En%5Cgeq%202.5%5C%5C2%281.08%29%5En%5Cgeq%202.5%5C%5C%24Divide%20both%20sides%20by%202%24%5C%5C%5Cdfrac%7B2%281.08%29%5En%7D%7B2%7D%5Cgeq%20%5Cdfrac%7B2.5%7D%7B2%7D%5C%5C%5C%5C1.08%5En%5Cgeq%201.25%5C%5C%5C%5C%24Change%20to%20logarithm%20form%5C%5Cn%20%5Cgeq%20%5Clog_%7B1.08%7D1.25%5C%5C%5C%5Cn%5Cgeq%20%5Cdfrac%7B%5Clog%201.25%7D%7B%5Clog%201.08%7D%20%5C%5C%5C%5Cn%5Cgeq%202.9)
Therefore, the smallest number of times Soon Yi will have to roll and fold the dough so that the resulting dough is at least 2.5mm thick is 3.
Answer:
A
Explanation:
The rate of urban growth in the world is decreasing.
The given statement about the identification of poor performers is a challenge that has existed since the earliest days of performance management is TRUE
<h3>What is Performance Management?</h3>
This refers to the corporate management tool that enables managers to track and analyze the work of their employers.
Hence, we can see that the identification of poor performers is a challenge that has existed since the earliest days of performance management and this also shows that the performance management process does not seem to be particularly good at weeding out poor performers.
