Answer:
Domain = [5,∞)
Step-by-step explanation:
Given: ![f(x)=-\sqrt{x}](https://tex.z-dn.net/?f=f%28x%29%3D-%5Csqrt%7Bx%7D)
We are given that f(x) is shifted right by 5 units.
Rule : f(x)→f(x-b)
The graph f(x) shifted b units right
So, using rule :
→
So, ![g(x)=-\sqrt{x-5}](https://tex.z-dn.net/?f=g%28x%29%3D-%5Csqrt%7Bx-5%7D)
Now to find domain:
![x-5>0](https://tex.z-dn.net/?f=x-5%3E0)
![x>5](https://tex.z-dn.net/?f=x%3E5)
So, Domain = [5,∞).
Answer:
(x−2)^3=x^3−6x^2+12x-8
Step-by-step explanation:
if you are talking about the binomial (x−2)^3 you must expand then simplify. (x-2)3 you would just remove the parenthesizes and multiply -2 with 3 to get x-6 but I think you meant (x-2)^3
We have to convert it to km/h
![\\ \sf\longmapsto 20\times \dfrac{3600}{1000}](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%2020%5Ctimes%20%5Cdfrac%7B3600%7D%7B1000%7D)
![\\ \sf\longmapsto 20\times \dfrac{18}{5}](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%2020%5Ctimes%20%5Cdfrac%7B18%7D%7B5%7D)
![\\ \sf\longmapsto 4times 18](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%204times%2018)
![\\ \sf\longmapsto 72km/h](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%2072km%2Fh)
The total amount of her savings 12,058.78
20 shares at 10 1/2 (or 10.5) = 20 * 10.5 = 210
20 shares at 11 1/4 (or 11.25) = 20 * 11.25 = 225
so the profit made would be : 225 - 210 = $ 15 <==
