- Which of the following is the solution of y'=ex+y under the initial condition y (0) = -1? You can find given options at the attachment. Thanks for your help.Suppose you own a restaurant and have a cook whose ability and attitude you are suspicious of. One ofthe dishes on the menu is duck cassoulet, which uses duck legs that have been slow fried over a couple of hoursin oil that does not exceed a temperature of 175 degrees. This is a time consuming and monotonous process,but one that results in excellent meat that you sell for a large mark-up. You suspect your cook is lazy anddoesnít properly monitor and maintain the oil temperature. You take a random sample of 12 duck legs andtake them to a forensics lab where you are able to discover the maximum temperature the meat has reached.Within your sample the mean maximum temperature of the duck legs is 182 degrees with a standard deviationof 5 degrees. Meat cooked precisely to 175 degrees is what your cook is supposed to do. Test the claim thatyour employee is capable (meaning he doesnít over-fry the meat) at the 90% conÖdence level.find 1.

- How do I solve this Bernoulli equation using P(x), Q(x) and n as well as u(y)?A scientist is studying three different cultures of bacteria {labeled "A", "B" and "C"} and wants to mathematically model the bacterial change of each type. To do this, the scientist decides to collect data for 25 consecutive days and builds the following scatter diagrams where the horizontal axis corresponds to "t" and the vertical axis to the amount of bacteria present in the culture P = P (t) Help the scientist decide which mathematical model (initial value problem) to use for each of the three types of crops. To do this, associate each of the graphs above with one of the following initial value problems. Crop type A a) dP/dt = k with P(0)=P0 and k>0.b) dP/dt = k with P(0)=P0 and k<0.c) dP/dt = kt with P(0)=P0 and k>0.d) dP/dt = kt with P(0)=P0 and k<0.e) dP/dt = kP with P(0)=P0 and k>0.f) dP/dt = kP with P(0)=P0 and k<0.g) dP/dt = kP(1-P/M) with P(0)=P0 and M, k>0.h) dP/dt = kP(1-P/M) with P(0)=P0 and M, k<0.
