we can check if a given sequence is geometric or not by checking the terms present in it ,
Let us find ratio of each term with it's previous term
if that ratio comes out same for every two consecutive terms then it is a geometric sequence , otherwise it is not geometric sequence .
Let us work on first one : given is : -1,1,-1,1.............
second term/ first term = 1/-1 = -1
third term/ second term = -1/1 = -1
fourth term / third term = 1/-1 = -1
fifth term/ fourth term = -1/1 = -1
because that ratio is same so it is a geometric sequence .
* let us now work with second sequence .
eE
second term/ first term = -6/-2 = 3
third term/ second term = -18/ -6 = 3
fourth term / third term = -54 / -18 = 3
hence this is also geometric sequence .
Answer : both are geometric sequence .
Answer:
Results are below.
Step-by-step explanation:
<u>First, we need to establish the decrease function in the given population:</u>
FV= PV/(1+g)^n
FV= future value
PV= present value
g= decrease rate
n= number of periods
<u>Now, for the given information:</u>
<u></u>
PV= 330
g= 22% = 0.22
n= 5 years
FV= 330 / (1.22)^5
FV= 122
L = 4D + 54 <== ur equation
the crew worked for 31 days...so sub in 31 for D
L = 4(31) + 54
L = 124 + 54
L = 178 miles <==
Answer:
true
Step-by-step explanation:
Answer:
B.
Step-by-step explanation:
You can't have the same X values for two different Y values
in this case 19 goes with 11 and 10 in the pairs (19,11) and (19,10)
