What is most confusing to you about this chapter? Post your own "muddiest point" within the 3 days before a test, and we will take the time to answer your question in class.

This is David Cohn...... so if you have the for the rate at which a ball falls which is h=-1/2gt2+v0t+h and you have the height....lets say 96 then how do you find what time the ball will be at that height

Boss, regression is easy. Get your data and scatter plot, then go to menu, select analyze, then select regression, then whatever you need, like quadratic or w/e. My question is, just to make sure i squared is -1 and just i is the square root of -1?

What is the point of a complex conjugate?

will i need to memorize every step of the quadratic regression for the test?

ReplyDeletehow do we know when to use a complex conjugate?

ReplyDeleteMy question is, just to make sure i squared is -1 and just i is the square root of -1?

greta, complex conjugate is used to remove i from the denominator in a fraction

ReplyDeleteIs there any way to determine if a parabola crosses the x-intercept just by looking at the equation?

ReplyDeletewhen an i in an equation is used would it mean that the number is multiplied by the square root of -1??

ReplyDeleteIs i always a negatvie one?
