Write a program that will ask the user to enter the amount of a purchase. The program should then compute the state and county s

iVinArrow [24]

Answer:

purchase_amount = float(input("Enter the amount of a purchase: "))

state_sales_tax = purchase_amount * 0.05

country_sales_tax = purchase_amount * 0.025

print("The amount of the purchase is " + str(purchase_amount))

print("The state sales tax is " + str(state_sales_tax))

print("The county sales tax is " + str(country_sales_tax))

print("The total sales tax is " + str(state_sales_tax + country_sales_tax))

print("The total of the sale is " + str(purchase_amount + state_sales_tax + country_sales_tax))

Explanation:

*The code is in Python.

Ask the user to enter purchase amount

Calculate the state sales tax, multiply purchase amount by 0.05

Calculate the county sales tax, multiply purchase amount by 0.025

Calculate the total sales tax, sum the state sales tax and county sales tax

Print the amount of the purchase, state sales tax, county sales tax, total sales tax and total of the sale

What would you have to know about the pivot columns in an augmented matrix in order to know that the linear system is consistent

Scrat [10]

Answer:

The Rouché-Capelli Theorem. This theorem establishes a connection between how a linear system behaves and the ranks of its coefficient matrix (A) and its counterpart the augmented matrix.

$rank(A)=rank\left ( \left [ A|B \right ] \right )\:and\:n=rank(A)$

Then satisfying this theorem the system is consistent and has one single solution.

Explanation:

1) To answer that, you should have to know The Rouché-Capelli Theorem. This theorem establishes a connection between how a linear system behaves and the ranks of its coefficient matrix (A) and its counterpart the augmented matrix.

$rank(A)=rank\left ( \left [ A|B \right ] \right )\:and\:n=rank(A)$

$rank(A)$

Then the system is consistent and has a unique solution.

$\left\{\begin{matrix}x-3y-2z=6 \\ 2x-4y-3z=8 \\ -3x+6y+8z=-5 \end{matrix}\right.$

2) Writing it as Linear system

$A=\begin{pmatrix}1 & -3 &-2 \\ 2& -4 &-3 \\ -3 &6 &8 \end{pmatrix}$ $B=\begin{pmatrix}6\\ 8\\ 5\end{pmatrix}$

$rank(A) =\left(\begin{matrix}7 & 0 & 0 \\0 & 7 & 0 \\0 & 0 & 7\end{matrix}\right)=3$

3) The Rank (A) is 3 found through Gauss elimination

$(A|B)=\begin{pmatrix}1 & -3 &-2 &6 \\ 2& -4 &-3 &8 \\ -3&6 &8 &-5 \end{pmatrix}$

$rank(A|B)=\left(\begin{matrix}1 & -3 & -2 \\0 & 2 & 1 \\0 & 0 & \frac{7}{2}\end{matrix}\right)=3$

4) The rank of (A|B) is also equal to 3, found through Gauss elimination:

So this linear system is consistent and has a unique solution.
