Answer:
g(x) = -|x|
Step-by-step explanation:
Are you familiar with the absolute value function y = |x|?
Its graph is v-shaped and opens up.
If the graph is turned upside down (so that it opens down), then g(x) = -|x|.
Answer:
![a_n=100 \left(\dfrac15\right)^{n-1}](https://tex.z-dn.net/?f=a_n%3D100%20%5Cleft%28%5Cdfrac15%5Cright%29%5E%7Bn-1%7D)
Step-by-step explanation:
General equation of geometric sequence: ![a_n=ar^{n-1}](https://tex.z-dn.net/?f=a_n%3Dar%5E%7Bn-1%7D)
Given:
![\implies a_1=a=100](https://tex.z-dn.net/?f=%5Cimplies%20a_1%3Da%3D100)
![\implies a_2=100 \cdot r=20](https://tex.z-dn.net/?f=%5Cimplies%20a_2%3D100%20%5Ccdot%20r%3D20)
![\implies a_3=100 \cdot r^2=4](https://tex.z-dn.net/?f=%5Cimplies%20a_3%3D100%20%5Ccdot%20r%5E2%3D4)
Common ratio:
![r=\dfrac{a_3}{a_2}=\dfrac{4}{20}=\dfrac15](https://tex.z-dn.net/?f=r%3D%5Cdfrac%7Ba_3%7D%7Ba_2%7D%3D%5Cdfrac%7B4%7D%7B20%7D%3D%5Cdfrac15)
Therefore:
![a_n=100 \left(\dfrac15\right)^{n-1}](https://tex.z-dn.net/?f=a_n%3D100%20%5Cleft%28%5Cdfrac15%5Cright%29%5E%7Bn-1%7D)
No
645 becomes 650 when rounded to the nearest ten
645 becomes 600 when rounded to the nearest hundred
Answer:
Look below
Step-by-step explanation:
First you multiply the top and bottom
5/12 x 6/7
5x6 and 12x7
you get your new fraction of 30/84
then you simplify it by 6 to get 5/14
hope this helps
