Answer:
I think it is option 2
since (x-h)^2+(y-k)^2=r^2
where h and k are the intercepts
Answer:
a
Step-by-step explanation:
sorry if wrong
Answer:Solve by simplifying for both sides of the equation, then isolating the variable.
Step-by-step explanation: x=0.4174294
Answer:
6a. r^5
6b. 18(4+√2)
Step-by-step explanation:
6a. The first term of the sequence is √r, and the common ratio is √r. Hence the 10th term will be ...
a1·r^(n-1) . . . for a1=√r and n=10.
√r·(√r)^(10-1) = (√r)^10 = r^5
_____
6b. The sum of n terms is given by ...
Sn = a1·(R^n -1)/(R -1)
For a1=√8 and the common ratio R = √8, the sum of 4 terms is ...
Or, you could add up the 4 terms:
