A tree is struck by lightning. The top part breaks and falls to the ground. The part of the tree still standing is 30 feet tall and the top part that hit the ground is 40 feet from the base of the tree. How tall was the tree originally?
integrate by parts integrate (4+x^2)^1/2
I'm sorry... I'm just not super comfortable posting my name on the web... Can you still please help me??
Which of the following definite integrals gives the length of y = e^(e^x) between x=0 and x=1? All the answers are preceded by the integral sign from 0 to 1. (a) sqrt[1 + e^(2*(x+e^x))] dx (b) sqrt[1 + e^(4x)] dx (c) sqrt[1 + e^(x+e^x)] dx (d) sqrt[1 + e^(2e^x)] dx (e) sqrt[e^...
Sorry but what do Ka/Kb values tell me?
I know caffeine is more polar than salicylic acid but how would I explain that given their respective structures? I know for smaller molecules you would figure out the polarity of individual bonds and the molecule's geometry but I can't figure out how to transfer this...
He's allowed to keep it is the fish is exactly 22 inches so you need to find the difference between 22 and the actual length of the fish (i.e. subtract how long the fish is from 22)
Please help. My teacher never went over crystal lattices and the book doesn't cover it either :( Copper crystallizes in a face-centered cubic lattice. If the edge of the unit cell is 351pm, what is the radius of the copper atom?
In what ways did China And Europe parallel each other in their development until the sixth century CE? How did they diverge after that?
