Answer:
Domain: X<5
Range: f(x)∈ R
Step-by-step explanation:
The sum of a geometric sequence is:
s(n)=a(1-r^n)/(1-r) in our case:
s(n)=3(1-4^n)/(1-4)
s(n)=-(1-4^n)
s(n)=(4^n)-1 and s=1023
(4^n)-1=1023
4^n=1024
n ln4=ln1024
n=(ln1024)/(ln4)
n=5
Answer:
12
Step-by-step explanation:
1/5 out of 20 is 4. So if you want 3/5 it would end up being 12.
The answer is -6 I put the work under here
