Which of the following sequences are not geometric? (check all that apply) a. 2,10,50,250,1250 b. 1,4,9,16,25,36 c. -4,-2,-1,-0.
Romashka [77]
A is geometric because each number is multiplied by 5.
B is not geometric because it is an arithmetic sequence.
C is a geometric sequence because each number is divided by 2.
D is neither geometric not arithmetic because there is no common ratio and there is not a pattern being added or subtracted to each number.
So, your answer should be B and D.
Answer: i dont know how exact you want it but the answer is 31.4159265359
Step-by-step explanation: you have to double the raduis and multiple buy pie.
Implicit differentiation
chain rule is important here
I'll show the steps partially




now evaluate for (-2,2)
x=-2 and y=2



that's it, simplest form
