? Let D a domain on the plane bounded by a curve C. by applying Green's theorem (in divergence form) to a conservative vector field with potential f, defined on d, show that before attempting this question, recall what is a conservative vector field, as well as the definition of the laplacian . ? Use the divergen

1.)The following formula can be used to convert from degrees Fahrenheit, F, to degrees Celsius, C: C= 5/9*(F -32) Gold is liquid for Celsius temperatures C such that 1063 degrees <= C < 2660 degrees. Find a comparable inequality for Fahrenheit temperatures. 2.) The following mathematical model: w = 125 (6400/6400 + x)^2

I am stuck with this question. If phi : F -> R is a nonzero homomorphism from a field F to a ring R, show that phi is one-to-one (Hint: recall that for a ring homomorphism, phi is one-to-one if and only if Ker(phi)={0}. ) Can you help with this? Many thanks in advance

10 algebra problems - work must be shown so I can understand how to compute. Examples of questions: --> Solve: x2 - 8x + 20 = 5 --> Solve by quadratic formula: -3x2 - 2x + 5 = 0 --> The crop yield in bushels for a field of tomatoes is 10x2 - 80x + 200 where x is number of pound of fertilizer used. a) How many pounds

Please use words to describe the solution process: What is the probability that the quadratic equation ax^2 + 2bx + c = 0 has real roots? Note: you must first make sense of the question. What distribution are you putting on the variables a, b and c? Pick one that makes sense and isn't too hard to deal with.

Suppose that distances are measured in light-years and that the temperature T of a gaseous nebula is inversely proportional to the distance from a fixed point, which we take to be the origin (0,0,0). Suppose that the temperature 1 light-year from the origin is 200 degrees Celsius. Find the gradient of T at (x,y,z). f = __

I'm having a difficult time figuring out some of these! For some reason the -1 in this problem is throwing me off - I think! Here's what I came up with last time, I keep getting a different answer each time I work it. 3/(y+5) -1 = (4-y)/(2y+10) 3/(y+5)-1 = (4-y)/2(y+5) y is not equal to -5 LCD is 2(y+5) 2(y+5)*3/(y+5) =
