Step-by-step explanation:
Answer:
= 8
Step-by-step explanation:
The n th term of a geometric sequence is
= a
where a is the first term and r the common ratio
Here a = 8 and r = - 24 ÷ 8 = - 3, thus
= 8
Answer:
For chess club:
y1 = 16 + 1*x where y1=total number of members after x months
For film club
y2 = 4 + 4*x where y2=total number of members after x months
y1 = y2 at
16 + x = 4 + 4x
3x = 12
x = 4
Therefore, after 4 months they the same number of members (equals 20 members, 16 + 1*4 or 4 + 4*4).
Volume = length * height * width
= 4 qrt3 + 3 sqrt6 * w
= 12 sqrt18 w
let w = 2 sqrt50 then volume = 2*12 * sqrt 18*50 = 24*30 so this is rational
let w = 4 sqt 12 the v = 48 sqrt12 * sqrt 18 = 48 sqrt30 which is irrational
C and D are rational
answer is B
