Answer:

Step-by-step explanation:

So you have two squares, one with a length of 20 on all sides, and onewith a length of 80 on all sides. It says the 80 one is a sclaed copy of the 20 one, so they took the 20 one and enlarged it to make the 80 one. You would divide 80 by 20 and get 4. This is how much the sides of the 20 one were multipled by to get the 80 one.

How do I solve question 13 and 14?

xxMikexx [17]

Answer:

13. 13 or 17 (not sure about this, sorry)

14. 28

Step-by-step explanation:

13.

$a_{n} = \{a_{0}, a_{1}, a_{2}, a_{3}, a_{4}, ... \} \\$

if counting the sequence from $a_{0}$ then $a_{4}$ is 17, but if

$a_{n} = \{a_{1}, a_{2}, a_{3}, a_{4}, a_{5}, ... \} \\$

counting from $a_{1}$ , then $a_{4}$ is 13.

14.

$a_{10} = 1 + 3(10 - 1) = 1 + 3*9 = 28$

How to calculate concentration with just the absorbance and % transmittance measurements from a spectrometer?

Natali [406]

Answer:

A=ε*l*c

A= 2- log₁₀ % T

Step-by-step explanation:

There is a linear relationship between the concentration of a sample and absorbance according to Beer-Lambert Law.

A=ε*l*c

where;

A=absorbance

ε=absorption coefficient

l=path length

c=concentration

Because % transmittance is transmittance value multiplied by 100 then, the equation that will allow us calculate absorbance from % transmittance value will be;

A= 2- log₁₀ % T where T is transmittance.
