Answer:
The value of x is D. 37°
Step-by-step explanation:
No need for math on this one, the angle next to x is 71° and is significantly bigger, so the only answer could be 37°.
1/8 or D, because 1/2 divied by 4 equals 1/8. Hope I helped! I need some help on one question for me.
Answer:
To measure EBC colour, the light absorption is detected at 430 nm (MEBAK 2.16. 2 respectively EBC 9.4). ... Then the absorption will be measured in a 10mm cuvette. The sample will be diluted until the absorption is less than 2 Extinction units (E430). EBC colour = E430 x 25 x dilution factor.
Step-by-step explanation:

Answer:
y is 1/4 when x is -1 if I did interpret your equation right. Please see that I did.
I believe the equation to be 
. If you meant 
, please let me know.
Thanks kindly.
Step-by-step explanation:
If (-1,y) lies on the graph of , then by substitution we have:
.
We just need to simplify to determine y:
Multiply the 2 and -1:
Use reciprocal rule for exponents to get rid of the negative:
just means 
:
.
Answer:
X = {0, 1, 2, 3, 4}
Step-by-step explanation:
If X is the number of nonzero digits in a 4-digit PIN with no restriction on the digits, the pin can have up to 4 nonzero digits.
Let's see some examples:
If the PIN is 0000 then X = 4
If the PIN is 2045 then X = 3
If the PIN is 7546 then X = 0
From the previous examples, we can see that the possible values for X are 0, 1, 2, 3, 4.
Thus X = {0, 1, 2, 3, 4}
