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.
1) (-4 . x) + (-4 . 3) = 8
-4x - 12 = 8
-4x = 20
x = 20/-4
x = -5
2) 3 = (3/4 . b) + (3/4 . -8)
3 = 3/4b - 6
3 + 6 = 3/4b
9 : 3/4 = b
3 . 4 = b
12 = b
3) (1/6 . p) + (1/6 . 24) = 10
1/6p + 4 = 10
1/6p = 6
p = 36
4) 3/5 . a + 3/5 . 5,25 = 7,35
3/5a + 3,15 = 7,35
3/5a = 4,2
a = 7
Answer:
he now owes $385.63
Step-by-step explanation:
owes $412.42
returns an item for $48.38
-412.42 + 48.38 = -364.04
he now owes $364.04
returns an item for $49.57
-364.04 + 49.57 = -314.47
he now owes $314.47
makes a purchase of $34.10
-314.47 - 34.10 = -348.57
he now owes $348.57
makes a purchase of $37.06
-348.57 - 37.06 = -385.63
he now owes $385.63
Answer: i ^ 59 = -i
Step-by-step explanation:
If you recall when simplifying imaginary numbers
i^1 = i* 1 = i
i^2 = i*i = -1
i^3 = i*i*i = -i
i^4 = i*i*i*i = 1
i^5 = i^4 * i =i
i^6 = i^4 * i^2 = -1
etc... the 4 values keep repeating
so take the exponent and divide by 4, the remainder is how many i values you have left to get your simplified answer of i, -1,-i, or 1
Remainder 1 i
Remainder 2 -1
Remainder 3 -i
Remainder 0 1
For infinitely many solutions, you must get each side of the equation to equal itself. So solve the first equation: 7 - 5 + 3x - 1
2 + 3x - 1
1 + 3x
Now make the blanks 3x and 1. For no solution, you can have anything other than x = an integer or x itself. If x = 2 + x, then it will have no solution. We have the solved equation: 1 + 3x. Fill in the blanks with 3x + any integer other than 1. For one solution, make it so x equals an integer. For example, you could fill in the blanks with 2x + 4, or anything other than 3x + 1 or 3x + any integer other than 1.
