Wow how do you not know how and what kind of bar are you talking about
Answer:
Domain:{3,5,6,9}Range:{8,2,1}
Step-by-step explanation:
The domain is the set of all the values of x
. The range is the set of all the values of y
Using proportions, according to the ratio of the partition, it is found that the location of point g is at 3.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, point g partitions the directed line segment from d to f into a 5:4 ratio, hence:
We have that d = -2 and f = 7, hence:
g + 2 = 5.
g = 3.

Answer:
y = 1/e
y = 0.37
Step-by-step explanation:
y = (ln x)/x; (e, 1/e)
Step 1
Find the point of tangency.
It's given as (e,1/e) or (2.72,0.37)
Step 2
Find the first derivative, and evaluate it at x=e
Using product rule.
d(uv) = udv + vdu
Where u = lnx and v = 1/x
du = 1/x , dv = -1/x^2
f'(x) = -lnx/x^2 +1/x^2
f'(x) = (1-lnx)/x^2
At x = e
f'(e) = (1-lne)/e^2
f'(e) = 0
The slope of the tangent line at this point is m= 0
Step 3
Find the equation of the tangent line at (e,1/e) with a slope of m=0
y−y1 = m(x - x1)
y-(1/e) = 0(x-1)
y = 1/e
y = 0.37
