If the null space of a 5 × 8 matrix A is 4-dimensional, what is the dimension of the column space of A? dim Col A-(Simplify your
Eva8 [605]

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.

How do I do this geometry problem?
lilavasa [31]

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...

Find the limit of the function by using direct substitution. Limit as x approaches zero of quantity x squared plus ten. Answer C
Oksi-84 [34.3K]

Answer:

D

Step-by-step explanation:

So we are given the limit:

\lim_{x \to 0} (x^2+10)

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

\lim_{x \to 0} (x^2+10)\\=(0)^2+10\\=0+10\\=10

Therefore, the limit equals 10.

Suppose an individual wants to have exactly $400,000 available for her child's education. (a) Find the amount that would have to
Airida [17]

Answer:  a) $135,838.21           b) $46,130.05

<u>Step-by-step explanation:</u>

A=P\cdot e^{rt}

  • 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

400,000=P\cdot e^{(0.12)(9)}\\\\400,000=P\cdot e^{1.08}\\\\\dfrac{400,000}{e^{1.08}}=P\\\\\large\boxed{135,838.21}

(b) Given:

  • A = 400,000
  • P = unknown
  • r = 12% = 0.12
  • t = 18

400,000=P\cdot e^{(0.12)(18)}\\\\400,000=P\cdot e^{2.16}\\\\\dfrac{400,000}{e^{2.16}}=P\\\\\large\boxed{46,130.05}
