Consider the initial value problem y''=y - y^2, y(0) 0.5 note that only two steps are needed. use euler's method with h 0.1 to obtain a four-decimal approximation of use the improved euler's method with h 0.1 to obtain a four-decimal find the exact solution to the differential equation in 9 (using y(0.2) approximation of y(0.2). methods from chapter 2) and find the percent relative error of numerical solutions in parts a. and b.

the answer to this question is yes

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

correct answer:
