Draw a tetragonal P lattice; place an extra lattice point in (½, ½, 0), i.e., make a C centering of the lattice. Now, show that a tetragonal C lattice does not exist, i.e. that it is equivalent to (another) P lattice
I understand how to draw it, I just don't know how to prove that its equivalent to another P lattice

(1 point) A Bernoulli differential equation is one of the
form
dydx+P(x)y=Q(x)yn (∗)
Observe that, if n=0 or 1, the Bernoulli equation is linear. For
other values of n, the substitution u=y1−n transforms the Bernoulli
equation into the linear equation
dudx+(1−n)P(x)u=(1−n)Q(x).dudx+(1−n)P(x)u=(1−n)Q(x).
Consider the initial value problem
y′=−y(1+9xy3), y(0)=−3.
(a) This differential equation can be written in the form (∗)
with
P(x)= ,
Q(x)= , and
n=.
(b) The substitution u= will transform it into the linear
equation
dudx+ u= .

It is a widely accepted option to place you child in the care of
a daycare center, but recent research suggests long-term
participation might have unanticipated consequences. One benefit of
daycare shows little difference of strength of parental attachment
bonds and it might even enhance some aspects of development. On the
other hand, some research points in a less positive direction. An
infant could feel less secure in an area with multiple infants
around. Also, the more hours children spend...

Forest Fires
By Sarah Kay
2010
I arrive home from JFK in the rosy hours to find a brand new
five-in-one egg slicer and dicer on my dining room table.
This is how my father deals with grief.
Three days ago, I was in the Santa Cruz redwoods, tracing a
mountain road in the back of a pickup truck, watching clouds
unravel into spider webs.
Two days from now, there will be forest fires so thick, they

budget constraint isPXX+PYY =I.
(a) Given the consumer’s utility function, how does the consumer
view these two goods? In other words, are they perfect substitutes,
perfect complements, or are somewhat substitutable? (2 points)
(b) Solve for the consumer’s demand functions, X∗ and Y ∗. (5
