Select the correct answer from each drop-down menu. Solve this system of equations using a matrix inverse.

the 3rd option is right

step-by-step explanation:

the formula for converting absorbance to transmittance goes as:

a = log (1/t)  a = 2 - log(%t)  10^a = 1/t  t = 10^-a  %t = 100(10^-a)

so at the given value of a,   a = 1.5

%t = 100(10^-1.5)

%t = 3.16%

the answer would be 9 because if it is perpendicular to the green line. the red lines slope is the opposite or reciprocal of the slope of the green line.
