A(n) = a₁.(r)ⁿ⁻¹, where a₁ = 1st term, r= common ratio and n, the rank
In the formula given a₁ = 5, r = 3/2 and n = 6 (we have to find the 6th term value).
a₆ = 5.(3/2)⁶⁻¹ = 5.(3/2)⁵ = 1215/32 (answer C)
Well it is true if the problem is the right with the right answer. If not you have a false eqaution.
Step-by-step explanation:
Scale Factor of UVW to XYZ
= XY/UV = YZ/VW = XZ/UW
= 21/3 = 28/4 = 14/2
= 7. (B)
Answer:
The system is consistent because the rightmost column of the augmented matrix is not a pivot column.
Step-by-step explanation:
It is given that the coefficient of the matrix of a linear equation has a pivot position in every row.
It is provided by the Existence and Uniqueness theorem that linear system is said to be consistent when only the column in the rightmost of the matrix which is augmented is not a pivot column.
When the linear system is considered consistent, then every solution set consists of either unique solution where there will be no any variables which are free or infinitely many solutions, when there is at least one free variable. This explains why the system is consistent.
For any m x n augmented matrix of any system, if its co-efficient matrix has a pivot position in every row, then there will never be a row of the form [0 .... 0 b].
Answer:
elevation of 3,234 feet above sea level Positive
losing $32.50 Negative
depositing $230 in an account Positive
withdrawing $2,432 from an account Negative
2°C below 0°C Negative
10 floors above ground level Positive
Step-by-step explanation:
elevation of 3,234 feet above sea level Positive This is above ground
losing $32.50 Negative it is less than you had
depositing $230 in an account Positive putting money in
withdrawing $2,432 from an account Negative taking money out
2°C below 0°C less than 0
10 floors above ground level above 0
