Answer: The concentration of X is 7.13582\times 10^{-6} and the concentration of Y is 2.53159\times 10^{-5}.

Step-by-step explanation:

Since we have given that

At 272 nm, absorbance = 0.215

At 327 nm, absorbance = 0.191

As we have given that

                               Compound X             Compound Y

272                               16400                            3870

327                                3990                             6420

So, our equations becomes

16400C_1+3870c_2=0.215\\\\3990C_1+6420C_2=0.191

By solving these two equations, we get that

C_1=7.13582\times 10^{-6}\\\\C_2=2.53159\times 10^{-5}

Hence, the concentration of X is 7.13582\times 10^{-6} and the concentration of Y is 2.53159\times 10^{-5}.

Step-by-step explanation:

suplementary angles add up to 180 degrees so

<4 + <3=180

<4 + <1 =180

<4 + <7=180

<4 + <5= 180

(1.) decide if function f is invertible.
Lubov Fominskaja [6]
<span>a) f(n) is the number of students in your calculus class whose birthday is on the nth day of the year.

f(n) is not invertible because several different days, n, may have the same number of students, f(n). Then for one specific f(n) you cannot determine a unique n.

b) f(x) is the volume in litters of x kilograms of water at 4 degrees celsius.?

f(x) is invertible because each x gives a different f(x), then you can determine unambiguously which f(x) corresponds to each x.
