A pivot in every row means that the linear system A x=b has at least one solution, for every b.

If every column has a pivot, then the linear system A x=b has at most one solution.

If both hold (which can happen only if A is a square matrix), we get that the system A x=b has unique solution for every b.

A pivot in every row is equivalent to A having a right inverse, and equivalent to the columns of A spanning

[tex]$\mathbb{R}^m$ ( $m$[/tex] is the number of rows).

A pivot in every column is equivalent to A having a left inverse, and equivalent to the columns of A being linearly independent

A pivot means fundamentally changing the direction of a business when you realize the current products or services aren't meeting the needs of the market. The main goal of a pivot is to help a company improve revenue or survive in the market, but the way you pivot your business can make all the difference.

Answer: m = 22

Step-by-step explanation:

First, you subtract $2.50 from the total of $79.50 (because that is the static fee) to get $77.00. Now, because every mile is $3.50 and we want to find the number of miles, we divide $77 by $3.50 to get 22. (An easy way to do this mentally is to divide 77 by 7 and multiply by 2.) Therefore, m = 22.

Answer:

Step-by-step explanation:

You want the (a) post-order, and (b) pre-order list of visited vertices in a traversal of the tree described by {root, left, center, right}: {d, f, {b, i, h, e}, {a, {c, g}}}.

A tree is traversed in post-order by visiting the left branch, center branch, and right branch before the root. This is accomplished recursively.

For the given tree, the root 'd' has left branch 'f' which has no branches. That means node 'f' is reported first.

The middle branch goes to 'b' which has three branches. Those are reported before their root 'b'.

The right branch from root 'd' goes to 'a', which has branch 'c' going to 'g'. So, 'g' is reported, then 'c', then 'a'.

Finally, 'd' is reported.

Hence, the post-order traversal is f, i, h, e, b, g, c, a, d.

The pre-order traversal reports the root node, then the left, center, and right nodes, recursively. The vertices are effectively visited in the order in which we have defined the tree above: d, f, b, i, h, e, a, c, g.

(a) The Explicit Rule for f(n) is 0.1 × 3n The Recursive Rule for f(n) is f(n-1) × 3.  (b) The Explicit Rule for f(n) is 100 × 0.1ⁿ The Recursive Rule for f(n) is f(n-1) × 0.1

The explicit rule states that the value of the sequence at each term is 0.1 multiplied by 3 raised to the power of n. The recursive rule states that the value of the sequence at each term is equal to the value of the preceding term multiplied by 3. This can be seen in the table of values where each value is 3 times the preceding value.

Given,        

n = 0,1,2,3,4…        

f(n) = 0.1,0.3, 0.9, 2.7, 8.1

(b) The Explicit Rule for f(n) is 100 × 0.1ⁿ, The Recursive Rule for f(n) is f(n-1) x 0.1

Given,      

n= 0,1,2,3,4..      

f(n) = 100, 10, 1,0.1, 0.01

The explicit formula is the formula to calculate the value of the sequence directly without using any previous terms. The recursive formula uses the previous term to calculate the value of the current term.

In this example, the explicit formula is 100 × 0.1ⁿ and the recursive formula is f(n) = f(n-1) × 0.1. This means that each term in the sequence is equal to the previous term multiplied by 0.1.

For example, the third term in the sequence is 1, so the fourth term is 1 × 0.1 = 0.1.

(c) The Explicit rule for f(n) is 1000 × 0.1⁽ⁿ ⁻ ¹⁾, The Recursive rule for f(n) is f(n-1) x 0.1    

To solve,

f(5) = 1000 × 0.1⁽⁵ ⁻ ¹⁾(5-1)

     = 1000 × 0.1⁴

     = 1000 × 0.0001

     = 0.1

Given,        

n= 1,2,3,4,5…        

f(n) = 1000, 100, 10, 1, 0.1

The explicit and recursive rules for this geometric sequence are both written as f(n) = 1000 × 0.1⁽ⁿ ⁻ ¹⁾.  This means that the value of the sequence at any given point n will be equal to 1000 multiplied by 0.1 raised to the power of n-1. This means that the value of the sequence decreases by a factor of 0.1 for every increase in n.

In this case,

f(5) = 1000 x [tex]0.1^4[/tex]

     = 0.1.

(d) The Explicit Rule for this geometric sequence is f(n) = 10⁽⁵⁰ ⁻ ³ⁿ⁾, where n is the term number of the sequence.

The Recursive Rule for this geometric sequence is f(n) = f(n-1) ÷ 10³, where f(n) is the value for the nth term of the sequence and f(n-1) is the value for the (n-1)th term of the sequence.

Given,    

n= 1,2,3,4,5..    

f(n) = 10⁵⁰,10⁴⁷, 10⁴⁴, 10⁴¹, 10³⁸….

The value for the 5th term of the sequence is f(5) = 10⁽⁵⁰ ⁻ ³⁽⁵⁾⁾ = 10³⁸. The explicit rule for this geometric sequence is f(n) = 10⁽⁵⁰ ⁻ ³ⁿ⁾, where n is the term number of the sequence. This means that the value of each term is determined by taking 10 to the power of 50 minus 3 multiplied by the term number.

The recursive rule for this geometric sequence is [tex]\frac{f(n-1)}{10^3}[/tex] which means that the value of each term can be calculated by dividing the previous term by 10 cubes. We can use

At year-end, Factory Overhead is debit of $34000.

A profit and loss (P&L) statement could be a monetary report that has a outline of a company’s revenue, expenses and profit. It provides investors and alternative interested parties an insight into however an organization is working and whether or not it's the flexibility to get a profit.

Main Body:

Estimated total overhead costs = $456,000

Estimated direct labor costs = $2,280,000

Actual overhead costs= $422,000

Actual direct labor costs= $1,940,000

To calculate the factory overhead, we need to first calculate Estimated overhead rate.

Estimated overhead rate = Estimated total overhead costs / Estimated direct labor costs

= $456,000 / $2,280,000

= 0.2

= 20%

Therefore;

Actual Factory overhead = Actual direct labor cost × application rate

= $1,940,000 × 20%

= $388,000

We can get the balance in the overhead account as shown below;

Balance = Actual overhead cost - Actual cost that should be applied

= $422,000 - $388,000

= $34,000 (Debit).

Hence there is debit of $34000.
