Answer:
Step-by-step explanation:
The point-slope equation of a line is
,
where
and the point is
Let's find the slope.
We are asked to use the first point in the equation, so
and 
The equation is:
The answer to the question is c. If you are in multiplying, 8(2)= 16 & 3(3)= 9
Hello from MrBillDoesMath!
Answer:
a^6 + 4 a^5 + 5 a^4 - 5 a^2 - 4 a - 1
Discussion:
You may need to clean things up a bit but suppose that
S(1) = a-1
S(2) = a^2 -1
Since this is a geometric series, the geometric ratio is given by
S(2)/ S(1) = (a^2 -1)/ (a-1)
= (a+1)(a-1)/ (a-1)
= a+1
Conclusion:
S(2) = (a+1) S(1) = (a+1) (a-1)
S(3) = (a+1) S(2) = (a+1) (a+1) (a-1) = (a+1)^ (3-1) (a-1)
S(4) = (a+1) S(3) = (a+1) * (a+1)^2 (a-1) ) = (a+1)^(4-1) (a-1)
in general.....
S(n) = (a+1)^ (n-1) (a-1)
So
S(6) = (a+1)^ (6-1) (a-1)
= (a-1) (a+1) ^ 5
= a^6 + 4 a^5 + 5 a^4 - 5 a^2 - 4 a - 1
Hope I didn't screw something here!
Thank you,
MrB
Answer:
D.
Step-by-step explanation:
Least value = 22 and greatest = 30
Arrange in order:
22 22 23 23 24 25 26 27 28 30
So the median is the mean of the middle 2:
= (24+25)/2 = 24.5.
Also Q1 = 23 and Q3 = 27
So the correct plot is D.
