You are spot on
Sim_SG3The coordinate geometry is not tested on the Focus but the underlying concepts are, though they are expected to be solved algebraically rather than graphically.
Also while I know Geometry is officially out of the test, I did run into this question on the GMAT Prep Focus Edition:
https://gmatclub.com/forum/a-spherical- ... 16425.html.
A spherical balloon originally had a radius of x centimeters. The balloon was partially deflated by letting out some air so that the volume of the balloon decreased by a%. If the balloon remained spherical while the air was being let out, which of the following expressions in x and a gives the radius, in centimeters, of the partially deflated balloon?
(Note: The volume of a sphere with radius r is \(\frac{4}{3}πr^3\).) |
When GMAC said there was no geometry on the GMAT Focus, I think it was more of a reference that you are not expected to know/remember formulas for various geometrical functions and operations. As you can see the volume formula is given here and this is a word problem but heavily relying on the geometric concepts. I would guess Coordinate Geometry is the same way - you don't need to study it, but it may be used as a background for the question.

Hi wanted to ask if coordinate geometry is in the portion for the focus edition? - There is a chapter in
TTP but its pretty small
Also has anyone seen any coordinate geometry questions in the official practice tests?
Hi! I've yet to take the official practice tests, but I do have the OG and Quantitative Review Guide, and I know coordinate graphs are part of the syllabus to the extent of slopes and intercepts. At least, that's the extent to which we see this topic in the Official Guide.
I don't think the Focus Edition has coordinate geometry in the "geometry" sense, where for example, you find the area of a figure denoted by points in the graph.
Thanks,
Sim
