Answer:
Percentage of light that penetrates at 150 m will be 0.94%.
Step-by-step explanation:
By using logarithmic regression calculator,
Equation of the regression line will be,
y = 104.5173 - 20.6711(lnx)
Where x represents the depth of the ocean
And y will represent the penetration of light
Therefore, at the depth of 150 m, penetration of the light will be,
y = 104.5173 - 20.6711[ln(150)]
= 104.5173 - 103.5753
= 0.9420
≈ 0.94 %
Therefore, percentage of light that penetrates at 150 m will be 0.94%.
The number of gallons of water in the bathtub is a function of time. Therefore, it is true.
<h3>
How to illustrate the graph?</h3>
The graph shows a curve that lets you find the number of gallons of water given any value of t betweeh 0 and 30 plus.
Hence, the number of gallons of time indeed is a function of time, in the interval shown by the graph.
The answer is true, because each t value is paired with exactly one number of gallons".

Answer:The answer is 25 units.
Step-by-step explanation:
here, ∡ABC=∡ACB
so, the given triangle is an isosceles triangle.
this means side AB and side AC are equal
so, you can write 4x+4=6x-14
solving this equation, we get x=9
finally, BC=2x+7=2*9+7=25
N = N₀* 
where N is how much you currently have
N₀ is the starting amount
t is the time
and h is the half life of the substance.
