1). Enrico Fermi directed construction of the the thing
that achieved the first sustained nuclear chain reaction,
under the stadium at the University of Chicago.
3). 'Fission' means splitting one big thing up into several
smaller things.
4). The atomic mass of an atom is close to the sum of all
the neutrons and protons in its nucleus.
5). 'Fusion' means several small things joining to form a
bigger thing.
6). Henri Becquerel is credited with discovering radioactivity.
7). The names of Madame Marie and Mssr. Pierre Curie were
appropriated after their deaths and used as the unit of radiation.
2). I have no idea what that symbol means, but 'neutron' is
the only choice left.
Answer:
The correct option is D.
i.e.
is the correct option.
The correct graph is shown in attached figure.
Step-by-step explanation:
Considering the function


![\mathrm{Range\:of\:}\frac{1}{x\left(x+4\right)}:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:f\left(x\right)\le \:-\frac{1}{4}\quad \mathrm{or}\quad \:f\left(x\right)>0\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-\frac{1}{4}]\cup \left(0,\:\infty \:\right)\end{bmatrix}](https://tex.z-dn.net/?f=%5Cmathrm%7BRange%5C%3Aof%5C%3A%7D%5Cfrac%7B1%7D%7Bx%5Cleft%28x%2B4%5Cright%29%7D%3A%5Cquad%20%5Cbegin%7Bbmatrix%7D%5Cmathrm%7BSolution%3A%7D%5C%3A%26%5C%3Af%5Cleft%28x%5Cright%29%5Cle%20%5C%3A-%5Cfrac%7B1%7D%7B4%7D%5Cquad%20%5Cmathrm%7Bor%7D%5Cquad%20%5C%3Af%5Cleft%28x%5Cright%29%3E0%5C%3A%5C%5C%20%5C%3A%5Cmathrm%7BInterval%5C%3ANotation%3A%7D%26%5C%3A%28-%5Cinfty%20%5C%3A%2C%5C%3A-%5Cfrac%7B1%7D%7B4%7D%5D%5Ccup%20%5Cleft%280%2C%5C%3A%5Cinfty%20%5C%3A%5Cright%29%5Cend%7Bbmatrix%7D)


So, the correct graph is shown in attached figure.
Therefore, the correct option is D.
i.e.
is the correct option.
-3x + 4y = 12
x - y = 1....x = y + 1
-3(y + 1) + 4y = 12
-3y - 3 + 4y = 12
-3y + 4y = 12 + 3
y = 15
x - y = 1
x - 15 = 1
x = 1 + 15
x = 16
one solution (16,15)
I think it would be D because it started off low then it started to increase
4+5y=20
-4 -4
------------------
5y=16
Divide by 5 on both sides
y=3.2
I hope this is what u wanted. :)
