Consider the region bounded by y=2-x2 and y=-x from x=-1 to x=2. Use a Right Riemann Sum to create an integral that calculates the area of the region. You don't need to evaluate the integral.

Use Euler's method with step size 0.4 to estimate y(0.8), where y(x) is the solution of the initial-value problem y' = -3X-2 +y^2, y(0) = -1 what is y (0.8)?

x=9t-3t^3, y=9t^2, 0<_t<_3

I'm confused about the role of the minus sign in gravitational acceleration calculations.g (9.8 m/s²) is always positive because it represents the magnitude of gravity and magnitude can never be... more

The company estimates that if x is spent on development and y is spent on promotion, then approximately (x^3/2*y^1/2)/80000 items of new product will be sold. Based on this estimate, how much... more

then approximately (x^3/2*y^1/2)/80000 items of new product will be sold. Based on this estimate, how much should the company spend on development so the maximum number of products can be sold?
