Answer:
C
Step-by-step explanation:
The other answers have inputs (x) that have multiple outputs (y) which goes against the definition of a function. For example in answer D zero has both the outputs of 7 and 52 which can not happen in order to be a function. However outputs can have multiple inputs just not the other way around.
Step-by-step explanation:
x+77=126 (vertical opposite angles are equal)
x=126-77
x= 49

Answer:
4) 0.001
Step-by-step explanation:
The amount (a) present in h hours is ...
a(h) = (initial value)×(1/2)^(h/(half-life))
6 days is 6×24 hours, so the amount remaining is ...
a(6×24) = 50×(1/2)^(6×24/9) = 50/2^16 ≈ 0.001 . . . . milligrams
Answer:
![\dfrac{1}{3}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B3%7D)
Step-by-step explanation:
Given length of purple line = ![\frac{1}{2}\ inch](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5C%20inch)
Given length of green line = ![\frac{1}{6}\ inch](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6%7D%5C%20inch)
To find:
How much longer is the purple line than the green line ?
Solution:
To find the required length, we have to subtract the length of green line from the length of purple line.
i.e.
The required answer =
![\frac{1}{2}-\frac{1}{6}\\\text{Taking LCM of 2 and 6, we get 6}\\\Rightarrow \dfrac{3-1}{6}\\\Rightarrow \dfrac{2}{6}\\\Rightarrow \bold{\dfrac{1}{3}}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D-%5Cfrac%7B1%7D%7B6%7D%5C%5C%5Ctext%7BTaking%20LCM%20of%202%20and%206%2C%20we%20get%206%7D%5C%5C%5CRightarrow%20%5Cdfrac%7B3-1%7D%7B6%7D%5C%5C%5CRightarrow%20%5Cdfrac%7B2%7D%7B6%7D%5C%5C%5CRightarrow%20%5Cbold%7B%5Cdfrac%7B1%7D%7B3%7D%7D)
Therefore, the <em>answer</em> is:
Purple line is
of an inch longer than the green line.
