The function that has a vertical asymptote at x= 8 is: [(x+5)(x+8)]/(x+8).

Find the inverse of g(x) = 5x - 8

Weegy: The inverse of g(x) = 5x - 8 is g^-1(x) = (x+8)/5. Your answer is g^-1(x) = (x+8)/5. (More)

Find the missing terms of the geometric sequence: 3, _, _, _, 768

Weegy: the third term would be the geometric mean between the first and the fifth: a3=sqrt(3x768) =48. Likewise the second term is the geometric mean between a1=3 and a3=48, a2=sqrt(3x48) =12 So,r=4: 3,12,48,192,768 2. [ [ 20r=48, r=48/20=12/5 5, 12, 144/5, 1728/25 which is not 20. You have something wrong with the sequence. 3, 12, 48, 192, 768 ] (More)

Mr.BreadMan

The missing are geometric sequence: 3,12,48,192,768.

In a geometric sequence you multiply by some number r to get to the next term. You can think of each comma as a sign telling you to multiply by r.

If we call our missing terms a, b, c we know that
3.ra
3.r.rb
3.rrr = c
aaand
3.r.rr. r = 768
3.4 = 768
768
3 768 p4
3 256 p4 -
r = 4
now we can find a, b, and, c pretty easily
a = 12
b = 48
c = 192
