My teacher has set me questions for maths homework and I haven't even been taught how to do them. Here is one of the questions, if someone could do the question and explain what they are doing as they go along, that would be more than fantastic...

Question: Find the coordinates of the points where the straight line meets 'y=1' meets the circle 'x^2+y^2-14x+2y+45=0'.

Once I can do one, I can do the rest of them.

Thanks

- Luke :)

Euglena is single-celled protist that can act as an animal or a plant but usually photosynthesizes. in my project i am adding caff to euglena. caff will probably cause euglena to CONTRACT. Recently i learned that caff can also cause euglena to form a cyst to protect itself if there was so much caff. Is CONTRACTING EUGLENA the same thing as CYSTED EUGLENA? b/c when i look@ pix it shows the same thing: euglena in a very round shape (euglena is usually elongated) WHAT IS THE DIFF? is 1 just a contration euglena forms in its euglenoid movemnet & 1 actually is like a shield? my caff in ea. is 5mg, 10mg, and 16 mg. I will observe it under a microspoe and to test my hypothesis (more caff=more cysts or contracted forms) and i will count out of total euglena how many are in normal shape and how many are in constant contracted/cyst form. if u have info against/for my hypothesis please share. and I Still Need Tips on CAre for Euglena. Nutrients they need? they arnt alwys in light...THANKS:)

first how do you find the altitudes, then what do you do to find the orthocenter? without graphing it how do you do it algebraically? thanks to anyone who helps me! this big project is due tomorrow...and of course...i put it off...lol

How do you calculate the area bounded by ln(x) and x-2?
As I can't solve ln(x)=x-2 I'm not sure what to do here.
