Explain how you could write a quadratic function in
factored form that would have a vertex with an x-
coordinate of 3 and two distinct roots.

The mean of a set of data is -3.82 and its standard deviation is 2.31. find the z score for a value of 3.99.

Polynomial that can be factored as (3x-4)(3x+4)

Expresa commuter train leaves downtown sation and travels at a average speed of 55 miles per hour towards the north side sation, which is 50miles away. thirty minutes later, express commuter train #7 leaves north side and travels at a average speed of 35miles per hour towards downtown sation. at the moment the two trains pass each other, how far(in miles) is train #12 from the downtown sation and how long(in minutes) has the #12 train been traveling
