If the percent transmittance for a sample is 50 at 350 nm what is the value of a

LenaWriter [7]

Answer: The value of absorbance is 0.3010

Step-by-step explanation:

Transmittance,(T)= 50%

Absorbance, (A)= ?

$A=-\log(\frac{T\%}{100})$

Transmittance and absorbance are inversely related:

$A=-\log\frac{50}{100}=0.3010$

Hence,the value of absorbance is 0.3010 when transmittance was 50%.

Sebuah balok berukuran panjang 3 cm, lebar 4 cm, dan panjang diagonal ruang 13 cm. Volume balok adalah

kramer

Answer:

$V=144\ cm^3$

Step-by-step explanation:

#We use the base diagonal and the height diagonal to calculate the beam's height:

$h=\sqrt{13^2-(4^2+3^2)}\\\\h=12\ cm$

#The volume of the beam can then be calculated as:

$V=lwh\\\\=4\times 3\times 12\\\\=144\ cm^3$

Hence, the beam's volume is $144\ cm^3$

How does the graph of f(x)=3|x+2|+4 relate to its parent function

Mariana [72]

If parent functin is f(x)=|x|
it is moved to the left 2 units
vertically streched by a factor of 3
and moved up by 4 units in that order

because
to move a function to left c units, add c to every x
to vertically strech function by factor of c, multiply whole function by c
to move funciotn up c units, add c to whole function

so it is 2 to the left, verteically streched by a factor of 3 then moved up 4 units
