Answer:
It would\ be -7 F.
Step-by-step explanation:
Answer:
a7=4/3 or a7=-4/3
Step-by-step explanation:
using the geometric sequences formula
an=ar^n-1
a2=ar
a4=ar³
when a2=324 and a4=36
324=ar...........(1)
36=ar³............(2)
from equation (1) a=324/r substitute in equation (2)
we have :
36=324/r *r³
36=324r²
r²=36/324
r²=1/9
r=±1/3
substitute when r=±1/3 in (1)
324=a(±1/3)
a=±972
so the 7th term is
when r=±1/3
we have
a7=ar^6
a7=±972(±1/3)^6
a7=972/729
a7=4/3 or a7=-4/3
1,5,25
I write all the multiples that equal 25 out,
Mark ME as Brainiest
Answer:20 milkshakes
Step-by-step explanation: 80 x 25% =20
25% or 1/4 of 80 is 20 if that makes sense to you.
The y intercept is 0,-13.5 and the x is -6,0
