Step-by-step explanation:
60 divided by 7 is 8.5
Answer:
x = 3.8
Step-by-step explanation:
The equation is (5 - x) / 2 = 2x - 7
Multiply both sides by 2:
5 - x = 4x - 14
Add 14 to both sides:
19 - x = 4x
Add x to both sides:
19 = 5x
Divide both sides by 5 to isolate x:
3.8 = x
Therefore, x = 3.8.
Answer:
x =
Step-by-step explanation:
Data provided in the question:
f'(x) = cos(ln x)
For finding points of maxima or minima , put f'(x) = 0
therefore,
cos(ln x) = 0
or
cos(ln x) =
or
ln x =
or
x =
now to check for maxima or minima at x =
f"(x) =
thus
at x =
f"(x) =
=
= < 0
hence maxima at x =
