how do you graph the equation y=-2cosx?

Is y equal to cotx, tanx, cosx, or sinx if its graph is periodic with a period of 2pi, an amplitude equal to 1, and it passes through the origin?

we haven't discussed log properly yet! It's supossed to be on the RAT, but IDK. . . this is about as much as I know: if you have log(X) 2401 = 4, then x equals 7. One of the simulated questions asks to express 3log(2) p + 4log(2) Q - 2log(2) R. please hel...

if you mean x squared minus negative six x plus nine, then you get: (x-3)squared, where x is not equal to zero.

dongo is right, but I thought I would add this to it: 1)Banks don't get interest; they give it to businesses and the general public because the infaltion rate exists. Banks can only get the interest payments that businesses make after they get loans. Besi...

I know I had Chemistry last year, but I'm not 100 percent sure about this answer: 21. you need 2 atoms each of each element. Divide 54 by 2, so you get 27 Ba atoms in groups of 2. 21 is already 2 O atoms. So you get 27 and 21. the smaller one is 21, which...

thanks.
