I got the same thing!
\(\frac{1}{\sqrt{10}}\)
Nice work! I guess you have that many upvotes for a reason
Doesn't look like it, but I would just like to check.
hint:
Either:
average the solutions for x
find the vertex
Well
your name certainly is correct then
62) Just solve the system...?
Expand:
18+3x=8x-3x
Move all x to right:
18=8x-3x-3x
Combine:
18=2x
Divide by 2:
9=x
why was the previous picture "blocked by moderator!"?
Triangle with legs 12 & 16 has a hypotenuse of 144+256=400, sqrt400=20.
Now, realize that these are similar triangles (as an exercise, figure out why!)
So, we have 20:16=x:20
Solve that.
You can factor and use the circle formula, which is:
\((x – h)^2 + (y – k)^2 = r^2\)
the center (h, k) and the radius r
Hmmm
nevermind
I got it right
you can still solve if you want though :p
Ah
I feel so dum
And I think that they are the only 2 missing, right?
THHHHHT
HHHHHTT

Yes, i think that's it.
So... \(\frac{8}{2^7}=\frac{8}{128}=\frac{1}{16} \)
THANQ
