] Find the vector form of the general solution to the given linear system Ax = b. Then use that result to find the vector form of the general solution to Ax = 0.

Answers

This question is incomplete, the complete question is;

Find the vector form of the general solution to the given linear system Ax = b; Then use that result to find the vector form of the general solution to Ax = 0.

x1 + x2 + 2x3 = 5

x1 + x3 = -2

2x1 + x2 + 3x3 = 3

Answer:

the vector form of the general solution to the given linear system Ax = b

x1 -2 -1

x2 = 7 +s -1

x3 0 1

find the vector form of the general solution to Ax = 0.

x1 -1

x2 = s -1

x3 1

Step-by-step explanation:

Given that;

x1 + x2 + 2x3 = 5

x1 + x3 = -2

2x1 + x2 + 3x3 = 3

Augmented matrix is expressed as;

1 1 2 5

1 0 3 -2

2 1 3 3

R2 ← R2 - R1

1 1 2 5

0 -1 -1 -7

2 1 3 3

R3 ← R3 - 2R1

1 1 2 5

0 -1 -1 -7

R3 ← R3 - R2

1 1 2 5

0 -1 -1 -7

0 0 0 0

R1 ← R1 + R2

1 0 1 -2

0 -1 -1 -7

0 0 0 0

R2 ← - R2

1 0 1 -2

0 1 1 7

0 0 0 0

SO from the above reduced matrix, we get

x1 = -2 - x3

x2 = 7 - x3

x3 = x3

now we introduce parameter "s" for free variable x3

x1 = -2 - s

x2 = 7 - s

x3 = s

x1 -2 -1

x2 = 7 +s -1

x3 0 1

General solution of Ax = 0 will be

x1 -1

x2 = s -1

x3 1

Darius filled up his gas tank with 24 gallons of gas. For each mile that he drives, he uses 0.06 gallons of gas. How may gallons of gas are left in the tank after driving 240 miles?

Answers

Answer:

9.6 gallons

Step-by-step explanation:

Step one:

Given that the capacity of the gas tank is 24 gallons.

we know that 1 mile will consume 0.06 gallons

therefore x miles will consume 0.06x gallons.

the consumption for any distance is given as

0.06x gallons.

Step two:

if x=240 miles

then the gallons consume will be

0.06(240)=14.4 gallons

Step three:

the remaining gallons of gas in the tank will be

24-14.4=9.6 gallons

The reamining gallons will be 9.6 gallons

The measure of an angle in standard position is given. Find two positive angles and two negative angles that are coterminal with the given angle. (Enter your answers as a comma-separated list.)

Answers

Answer:

The answer is below

Step-by-step explanation:

Let us assume the angle is -π/4.

Coterminal angles are angles that have the same initial side and terminal side. They are angles in standard position (angles with the initial side on the positive x -axis) that have a common terminal side.

Positive coterminal angles are gotten by adding 360° if the angle is in degrees or 2π for angles in radian while negative coterminal angles are gotten by subtracting 360° if the angle is in degrees or 2π for angles in radian.

Positive coterminal angle = -π/4 + 2π = 7π/4, 7π/4 + 2π = 15π/4

Positive coterminal angle = 7π/4, 15π/4

Negative coterminal angle = -π/4 - 2π = -9π/4, -9π/4 - 2π = -17π/4

Negative coterminal angle = -9π/4, -17π/4

Please help me quickly! 3.5.2 Practice for income tax

Answers

Answer:

$15,475

Step-by-step explanation:

Mr. and Mrs. Jones make a combined $92,400 in taxable income. Looking at the table, their income is over $67,900 but not over $137,050.

So, the tax is $9,350. But, it also includes 25% of the amount over $67,900.

So,

$92,400 - $67,900 = $24,500

0.25 × $24,500 = $6,125

$9,350 + $6,125 = $15,475

Answer:

it would be 5.41 x 10^2

Step-by-step explanation:

the reason it would be this is because when you have it ^2 you love the decimal that many places the same goes for the number was negative then you would move it backwards.

Answer:

The answer is 5.41 × 10^2

Step-by-step explanation:

To make sure the answer is right, picture a decimal on the right of the 1 in the numeral. Then, picture it going to the left until it's next to the 5. Since it moved twice, the exponent is 2 and the decimal is 5.41. Hope this helps!
