Answer:
Step-by-step explanation:
(w circle r) (x) is the composite function(w of r(x)), that is, w(r(x))[/tex]
We have that:
Composite function:
is a negative parabola with vertex at the original.
So the range(the values that y assumes), is:
Answer: 2/125
Step-by-step explanation: No esto 100% seguro pero hice esto:
2/5 % 4 = 2/125
The approximate percentage of light remaining after passing through 6 feet of water, to the nearest tenth of a percent is 4.7%
<h3>How is the percentage of light remaining at a depth of 6 feet calculated?</h3>
The percentage of light remaining is calculated from the percentage of light remaining after a depth of one foot each.
Percentage of light remaining after 1 feet = 100 - 40% = 60%.
Percentage of light remaining after 6 feet = 60% × 60% × 60% × 60% × 60% × 60% = 4.7%
Therefore, the approximate percentage of light remaining after passing through 6 feet of water, to the nearest tenth of a percent is 4.7%.

Answer: 36 feet
==================================================
Work Shown:
(sign height)/(sign shadow) = (pole height)/(pole shadow)
8/2 = x/9
8*9 = 2*x ... cross multiply
72 = 2x
2x = 72
x = 72/2 ... divide both sides by 2
x = 36
The utility pole is 36 feet tall.
