Answer: 450 cm
Step-by-step explanation:
10 x 9 = 90 x 5 = 450
The maximum rate of change occurs in the direction of the gradient vector at the given point, with magnitude equal to the norm of the gradient at that point.
Alright, this question is a bit confusing, but hopefully this will help:
Remember that Log(a) B = C is actually a^C = B. (Just imagine "a" as the little number that is first written after "Log.")
So here, I think Log(9) 0.877 = "x." And you want the value "x."
9^x = 0.877, which is all I've got, cause I don't really know what this "change of base rule" is. But I hope I helped.
Let's put it into perspective.
x/(x+5)
If increase by 3:
(x+3)/(x+8) = 3/4
Cross multiply.
4(x+3)=3(x+8)
4x+12 =3x+24
Solve algebraically.
4x-3x = 24-12
x = 12
Therefore, original fraction is:
12/17
