Answer:
9.5
Step-by-step explanation:
square root 90 and you get 3 square root of 10 which is around 9.486
Answer:
i also dont know
Step-by-step explanation:
18, you have 3 choices for the bottom because you can't use the small one, 3 choices for the next because you can now use the small one, 2 for the next and finally 1. You multiply all of them to get 18
You should definitely improve the quality of the image, because I can't see anything clearly.
Also, the 4th answer is hidden.
In the usual sense, it has no inverse function. Since it is not an injection (f(0)=f(2)=0), an inverse function would have to map 0 both to 0 and 2, and that’s impossible.
However, if you restrict the domain to [1,+oo> (to make it injective), and the codomain to [-1,+oo> (to make it surjective), then it has an inverse function, given by g(y)=1+sqrt(y+1).
