Answer: Dim Col A = 4.
Step-by-step explanation:
Since we have given that
Matrix A has 5 rows and 8 columns.
And Nul A = 4
It implies that the rank of A would be
Number of columns - Nul A = 8 - 4 =4
So, rank A = 4
so, it has dim Col A = 4 also.
But the four vector basis lie in R⁵.
Hence, Dim Col A = 4.
Answer:
x = 12
Step-by-step explanation:
I believe that the two tangents are equal to each other so 2x would be equal to x + 12, so you would subtract x from x + 12 and get x equals 12. I think...
Answer:
D
Step-by-step explanation:
So we are given the limit:

To figure out this limit, we can use direct substitution. Simply substitute 0 for x and then simplify. Therefore:

Therefore, the limit equals 10.
Answer: a) $135,838.21 b) $46,130.05
<u>Step-by-step explanation:</u>

- A: accrued amount (balance)
- P: principal (initial amount invested)
- r: interest rate (in decimal form)
- t: time
(a) Given:
- A = 400,000
- P = unknown
- r = 12% = 0.12
- t = 9

(b) Given:
- A = 400,000
- P = unknown
- r = 12% = 0.12
- t = 18

7 times 5 equal 35. Hope this helped
