Answer:
(-7)×(-7)=+49
You change the signs and multiple
Leave the whole number alone for now. Divide 41 by 80 and you get 0.5125
So your answer is 9.5125
Answer:
The average rate of change is ![\frac{18}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B5%7D)
Step-by-step explanation:
Given function that shows the population of a culture of cells,
![P(t)=\frac{90t}{t+1}------(1)](https://tex.z-dn.net/?f=P%28t%29%3D%5Cfrac%7B90t%7D%7Bt%2B1%7D------%281%29)
Where, t represents the number of weeks.
Thus, the average rate of change in the population over the interval [0,24],
![m=\frac{P(24)-P(0)}{24-0}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7BP%2824%29-P%280%29%7D%7B24-0%7D)
From equation (1),
![=\frac{\frac{90\times 24}{24+1}-\frac{90\times 0}{0+1}}{24}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5Cfrac%7B90%5Ctimes%2024%7D%7B24%2B1%7D-%5Cfrac%7B90%5Ctimes%200%7D%7B0%2B1%7D%7D%7B24%7D)
![=\frac{\frac{2160}{25}-\frac{0+1}{0}}{24}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5Cfrac%7B2160%7D%7B25%7D-%5Cfrac%7B0%2B1%7D%7B0%7D%7D%7B24%7D)
![=\frac{2160}{25\times 24}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B2160%7D%7B25%5Ctimes%2024%7D)
![=\frac{2160}{600}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B2160%7D%7B600%7D)
![=\frac{18}{5}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B18%7D%7B5%7D)
