I made some red jello to use as gore for halloween and I want to put it in my "bloodbath"/birdbath out the front of my house. The weather isn't hot (Colorado) but I'm still worried about it melting and disappearing on me. Therefore I'd like to know the temperature at which it will melt.

Has any scientist bothered to find out a theory of how this is possible?

I'm currently a Medical Technology/ Clinical Lab Science major. I've been told however that this job doesn't pay very well, with odd hours and sometimes unpleasant working conditions. I KNOW for a fact I want to do lab work, but I'm more interested in a lot of diagnostics and research. What would be a good career for someone who is more biology (not chemistry) minded, wants to work in a lab, likes to figure out the causes of things such as disease or genetic abnormalities, and how to diagnose it and fix it, and still make good money?

A rectangular field will be constructed near the Dog River with one side of the fiedl along the edge of the river (where the river is straight). No fence is needed along the riverbank. There is fence material available that is 400 meters long.
a) Suppose that the length of the fence (parallel to the river) is 80 meters.
Find the width of the fence (perpendicular to the river) and compute the area enclosed by the fence.
b) Suppose that the width of the fence (perpendicular to the river ) is 100 meters. Find the length of the fence (parallel to the river) and compute the area enclosed by the fence.
c) What length (parallel to the river) and width (perpendicular to the river) of the fence can you choose so that the area of the field is maximized? What is the maximum area that can be enclosed within the field?

Hi, Below is a question of polynomials. Could you please help me get to know how the answer is obtained in a detailed way? Please make sure u explain the answer and its steps clearly so that i can understand it. Thanks a lot in advance!!

Qn: When a polynomial, P(x), is divided by x-a, it leaves a remainder of a^3 and when it is divided by x-b, it leaves a remainder of b^3. Find the remainder when P(x) is divided by (x-a)(x-b).

Note -> The answer to this question is (a^2 + ab + b^2)x - ab(a + b). However, I dont have a single idea as to how u get this answer. So please explain clearly. VERY CLEARLY.

Thanks.
