It would be 1/8 I am pretty sure
f(x)=lnx
y=f(x)
dy/dx= 1/x
tangent at (x,y) has slope 1/x
eqn of tangent is y = mx + c
since the tangent passes through origin, c=0
substitute y = lnx and m= 1/x to above eqn
lnx = 1
x=e
y=lne=1
Answer:
The answer to |4a|=20 is a=5 or a=-5.
Step-by-step explanation:
180 - 155 = 25
90 - 25 = 65
