The following DEs are not solvable as written. Perform the given variable change to turn them into something that you are equipped to solve (e.g. either linear, separable or exact) and then find the general solution. Your answer should be in the form y(x)=...y(x)=...
a) dydx=x2+y2−2xydydx=x2+y2−2xy using u=y−xu=y−x
b) xdydx−y=x2−y2−−−−−−√x>0xdydx−y=x2−y2x>0 using u=yxu=yx
c) dydx=y(xy3−1)dydx=y(xy3−1) using u=1y3

Des/ign, implement, (Auto, Home, Life) as classes and test them, that represent different insurance policies.
Des/ign, implement, (Auto, Home, Life) as classes and test them,
that represent different insurance policies. A policy contains
information used by an insurance company to provide financial
assi/stance in the event of an accident. It also contains
information used to compute how much money, also called acommission. Develop instance variables, constructors,
get/set methods, and a toString method for each class. Create a
driver class called PolicyTest, whose main method creates objects
from each type of class, sets each object with...

The probability that a vehicle will change lanes while making a
turn is 55%. Suppose a random sample of 7 vehicles are observed
making turns at a busy intersection. a) Find the probability that
no more than 4 vehicles will change lanes while making the turn. b)
Calculate the expected value u of the vehicles that will change
lanes while making turn c) Calculate the standard deviation

The rate of change of the temperature of the coffee is given by
the following differential equation, where T is measured in degrees
Fahrenheit and t is in minutes. The time to reach a certain
temperature, T =185 F t = 4 min
dT/dt = 0.041(T – 75)
a. Use Euler's mothod with a stop size of 0.5 to estimate the
temperature of coffee after 5 minutes.
b. Analyses the effect of step size on the error use of
appropriate...
