I need help with this problem: Given the differential equation dy/dt = y^(3) - 0.75(1+t)y with initial condition y(0) = 1, what is the exact value of y'(0)?

How do you even begin to separate the variables? It seems to me like this is inseparable but I don't think they would give a problem that is inseparable. Thanks!

I wanted to make marshmallow brownies. So after I baked the brownies, i immediately started putting the marshmallows over the top. They weren't melting that great so i popped the brownie batch with the marshmallow on top back into the oven for a while. When i took them out, the outer layer of the marshmallow became a crunchy crust and only the inside was melted. So i didn't get the layer of melted marshmallow that i wanted, they were still in the form of balls. i even tried microwaving them but nothing changed.

i need to take them to school tomorrow, so do i need to keep them in the fridge? and will the marshmallows become too hard if i do keep them in the fridge?

my family has never really made turkey and all that stuff for thanksgiving and i was thinking id make some this thanksgiving. so i understand how u have to make stuffing and then stuff the turkey, but after the turkey is done, where does the stuffing go? is it served with the turkey, or as a side dish, or does the stuffing get its own plate? I'm planning on carving up the turkey in the kitchen rather than at the table. please help, thanks :)
