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%.

Answer:
the number of bacteria increases at a rate of 15% each day
Step-by-step explanation:
Given the function :
f(x) = 256(1.15)^x
The function represents an exponential growth function ; comparing the equation with the general form of an exponential growth function :
f(x) = A(1 + r)^t
A = the initial value of the population, = 256
(1 + r),; r = growth rate
Therefore, to solve for r ;
1 + r = 1.15
r = 1.15 - 1 ; r = 0.15
Hence, growth rate = 0.15 = 0.15 * 100% = 15%
Hence, the number of bacteria increases at a rate of 15% each day
