Answer:
7
Step-by-step explanation:
Just multiply all numbers together.
Plz give me brainliest
Sn=sum of the n terms of the geometric sequence.
a= the first term
r=the common ratio
n=numbers of terms.
Sn=a[(1-r^n)/(1-r)]
In this case:
a=-3
r=a₂/a₁=15/-3=-5
n=9
S₉=-3[(1-(-5)⁹) / (1-(-5))=
S₉=-3(1+1953125)/6)=
S₉=-3(1953126/6)=
S₉=-3(325521)
S₉=-976563
Answer: A. -976563
D. 11.75 + 3.299 + 5.31 + 6.27
Step-by-step explanation:
11.75 would round up to 12, 3.299 would round down to 3, 5.31 would round down to 5 and 6.27 would round down to 6
Rate of change is -2 because you can do rise over run to find the constant rate of change, and since you are going down you have a negative slope.
