The graph can be found here: http://www.wolframalpha.com/input/?i=f(x)%3Dx%5E2-2x
Well, anyway Vertex: (1,-1)
Focus: (1,-3/4)
Axis of symmetry: x=1
Directrix: y=-5/4
No problem!
19. w+7=length
w=width
So, w(w+7)=260
The positive value of w=13
So, the length is 13+7=\(\boxed{20}\)
Thank you so much, Melody!
Less than 3 means 2 and 1:
Number of accidents for 2: 0.35
Number of accidents for 1: 0.25
So, 0.6/100*100=0.6
Yes, it means factorial. So, let's say the question is asking 7!, or 8!=
So, 7*6*5*....*1
Here's why:
Total number of students in 10th grade that did not eat food served: 47
Total number of students in 10th grade: 63+47=110
Thus, 47/110=0.43 (rounded)
No problem, here anytime!
8P3=8!/5!=8*7*6=336.
Yes, very good, CPhill!
