Week 9 in Precalculus 11

Tell: Something we have learned this week is how to model and solve problems with quadratic functions.


One question I was stuck on was #5 on pg.323


I was stuck on this question because I didn’t know what to do after I got it into a=(20-w)w. Once I got help I discovered that I had to find the x intercepts and with that I proceeded to find my width, then plugged that into my equation I first made to find the length.
