I would say 2.5 becasue there are two lines between the -2 and -1 so it would be half. SO my awnser is 2.5
i hope this helped you
Have a good day
if it is wrong tell me
Answer:
The first one
y=1.3y+10
Step-by-step explanation:
Just test every solution,
Answer: 4.2!
Explanation: Just divide 25.2 by 6 and you have your answer!
A=84 and r=1/5
Since r, the common ratio squared is less than one, the sum will converge to a limit. Rule: if r^2<1 infinite series converges, otherwise it diverges.
Since the sum of any geometric sequence is:
s(n)=a(1-r^n)/(1-r)
And if r^2<1, (1-r^n) becomes 1-0=1 as n approaches infinity.
So whenever r^2<1 the sum of the infinite series is just:
s(n)=a/(1-r)
Since a=84 and r=1/5 this infinite series has a sum of:
s(n)=84/(1-1/5)
s(n)=84/(4/5)
s(n)=5(84)/4
s(n)=105
-5/4 , by using m= (y2-y1)/ (x2-x1)
