Step-by-step explanation:

Multiply by 6

And

Multiply by 3

eq(1)-eq(2)

Then

From Equation 1

\( \dfrac{x}{2} + \dfrac{2y}{3} = - 1 \)

\( \dfrac{3x + 4y}{6} = - 1\)

\(3x + 4y = - 6 \)

From Equation 2

\(x - \dfrac{y}{3} = 3 \)

\( \dfrac{3x - y}{3} = 3\)

\(3x - y = 9\)

By eliminating ;;

For that multiply equation 2 by 4

12x - 4y = 36 _(3)

By taking equation (1) and (3)

3x + 4y = -6

12x - 4y = 36

__________

15x = 30

x = 30/15

x = 2

Putting the value of x in 2

\(3(2) - y = 9\)

\(6 - y = 9\)

\(6 - 9 = y\)

\(-3 = y\)

So The value of x = 2 and y = -3

The matrix M that satisfies the given conditions is M = [3/2 -5/2; 3/2 5/2].

To find the variable y = [y1 y2] of the form y=Mx, where M is a matrix so that the differential equation x′=Ax, A=[4414] is diagonal for the variable y, given that this coefficient matrix A has eigenpairs λ1 = 6, v1 = [1 2], and λ2 = 2, v2 = [1 -2], we can use the following steps:

Step 1: Write the matrix A in terms of its eigenvectors and eigenvalues. The matrix A can be written as A = PD where D is a diagonal matrix with the eigenvalues on the diagonal and P is a matrix whose columns are the eigenvectors. Thus, we can find the matrices P and D as:

P = [v1 v2] = [1 1 2 -2]D = [λ1 0; 0 λ2] = [6 0; 0 2]

Step 2: Express y in terms of the eigenvectors. Since A and M have the same eigenvectors, we can express y in terms of the eigenvectors as y = Pz where z is a vector of constants. Therefore, we can find z.

Step 3: Express x in terms of the eigenvectors.

Since A is diagonal in the eigenvector basis, we can express x in terms of the eigenvectors as x = Pw where w is a vector of constants. Therefore, we can find w = x/P

Step 4: Express y in terms of x. We know that y = Mx. We can substitute the expressions for y and x in terms of the eigenvectors to get:

Mx = Py = PDz = P[Mz1 Mz2] = [6z1 2z2; 0 2z2]Thus, we can write M = PD = [1 1 2 -2][6 0; 0 2][1/4 1/4 -1/8 -1/8] = [3/2 -5/2; 3/2 5/2]

Answer:

Step-by-step explanation:

Given a triangle with angles 60° and 60°. Let the third angle be represented by x, so that;

x + 60° + 60° = \(180^{o}\) (sum of angle in a triangle)

x + 120 = \(180^{o}\)

x = \(180^{o}\) - 120

x = 60°

Thus, since the third angle of the triangle is 60°, then the triangle is an equilateral triangle. For an equilateral triangle, all sides are equal and all its angles are equal. So that the other sides of the triangle is 10 each.

Let f(x,y,z) = 5x³, − y³, z². 30.95 is the maximum value m for the directional derivative at the point (1,−3,1).

The word "derivative" is thought to come from the fact that the function in question is not the original function f, but rather a distinct function called f′(x) (x). Hence, the other function, let's say f, has been used to construct f'(x) (x). The primary distinction between derivatives and equity is the factor that determines the price or value. Equity's value is determined by factors in the market, such as supply and demand, as well as business and economic developments.

Contrarily, a derivative gets its value or price from the underlying asset, which could be an index, a stock, a currency, etc. Options, single stock futures, warrants, a contract for difference, and index return swaps are five of the more well-known derivatives.

Δf = <15x², -3y², 2z

Δf (1, -3, 1) = < 15 × (1)² , -3 × (-3)² , 2 × 1 >

Δf (1, -3, 1) = <15, -27, 2>

Normalizing yield

\(\hat{u} = \frac{\Delta f (1, -3, 1)}{|\Delta f (1, -3, 1)|}\)

\(|\Delta f (1, -3, 1)| = \sqrt{(15)^{2} + (-27)^2 + (2)^2}\)

                     \(= \sqrt{225 + 729 + 4\)

                     \(= \sqrt{958}\)

Answer:

$112.65

Step-by-step explanation:

7.25 x 8 = 58

58 + 54.65 = 112.65

The Total pay for the given information is $112.65 (Option a)

1. Calculate Regular Pay: Multiply the hours worked by the hourly wage.

  Regular Pay = Hours worked × Hourly wage

                       = 8 hours × $7.25/hour

                       = $58.00

2. Add Tips:

Add the tips to the regular pay.

Total Pay  = Regular Pay + Tips

                = $58.00 + $54.65

                = $112.65

So, the total pay is $112.65.

You are given the hours worked (8 hours), the hourly wage ($7.25), and tips ($54.65).

To find the total pay, you need to calculate the regular pay based on the hours worked and hourly wage.

Multiply 8 hours by $7.25 to get $58.00 as the regular pay.

Then, add the tips of $54.65 to the regular pay to find the total pay.

In the given options, the correct answer is Option a) $112.65. This is the final amount you would earn for working 8 hours at an hourly wage of $7.25 and receiving $54.65 in tips.

Answer:

0.0593, or 5.93%

Step-by-step explanation:

There are a total of 8 x 8 = 64 one-foot tiles in the foyer. Since two of them are cracked, there are 62 tiles that are not cracked.

To find the probability that the two cracked tiles share a common edge, we need to first determine the total number of pairs of adjacent tiles in the 62 remaining tiles. Each tile has four adjacent tiles (unless it is a tile on the edge of the foyer), so the total number of pairs of adjacent tiles is:

4 x (62 - 14) + 3 x 8 = 220

We subtracted 14 from 62 because there are 14 tiles on the edges of the foyer that only have three adjacent tiles, and we added 3 x 8 to account for the eight corner tiles that only have two adjacent tiles.

Next, we need to determine the number of ways that the two cracked tiles can be placed such that they share a common edge. There are 60 possible locations for the first cracked tile, and once it is placed, there are only 3 possible locations for the second cracked tile (it can only be placed in one of the three tiles adjacent to the first cracked tile). Therefore, the total number of ways that the two cracked tiles can be placed next to each other is:

60 x 3 = 180

Finally, we can calculate the probability by dividing the number of favorable outcomes (i.e., the number of ways that the cracked tiles can be placed next to each other) by the total number of possible outcomes (i.e., the total number of ways that the two cracked tiles can be placed):

P = 180/ (62 choose 2) = 180/ (62 x 61/2) = 0.0593 (approximately)

Therefore, the probability that the two cracked tiles share a common edge is approximately 0.0593, or 5.93%.

The length of A'B' = 5 units

The line segment AB is of 5 units. AB is then transformed through translation of 3 units to the right.

The translation only means change through a straight line. This transformation does not change the length of a line segment.

So the length of A'B' will also be 5 units.

But the position of A'B' will be different from that of AB on the co-ordinate plane. To be exactly, A'B' would be 3 units right to the position of AB on the co-ordinate plane.

Also the co-ordinates of A'B' will be different. Still their lengths will be same.

The maximum possible volume of the box is 4.5 cubic meters and this is achieved by having a square bottom of the box with a  side length of 3 cm and a height of 1/2 cm.

Volume is simply defined as the amount of space occupied by any three-dimensional solid. These solids can be a cube,  cuboid,  cone,  cylinder or  sphere. Different shapes have different volume. The formula for volume is: volume = length x width x height.

 Let the side of the base of the square  be x cm. Then the area of ​​the base would be x² square cm.

 The material needed to make the box would be the sum of the areas of the bottom and  four sides. Since the bottom of the box is square  and the sides are perpendicular to the base, the area of ​​each side is x times the height.

 So the total  area of ​​the box would be:

x² + 4 (x times height)

We know that the total  area is 16 square cm, so we can write:

x² + 4 (x times the height) = 16

We want to maximize the volume of the box. The volume of a square box  is obtained as follows:

V = x² times height

We can solve the first height equation with x:

height = (16 - x²)/(4x)

Substituting this height expression  into the volume formula, we get:

V = x² times (16 - x²)/(4x)

Simplifying this expression, we get:

V = (4x³ -\(x^4\))/16

We want to find the maximum value of V. To do this, we take the derivative of V with respect to x and set it  to zero:

dV/dx = (12x² - 4x³)/16 = 0

This gives us two solutions: x = 0 and x = 3.

 Since x represents the side of the square root, it must be positive. Therefore we choose x = 3.

 Substituting this value into the height expression, we get:

height = (16 - 3²)/(4 times 3) = 1/2

So the maximum volume of the box is:

V = 3² times 1/2 = 4.5 cubic meters

Therefore, the maximum possible volume of the box is 4.5 cubic meters and this is achieved by having a square bottom of the box with a  side length of 3 cm and a height of 1/2 cm.

At 2 drinks, the prices are equal. For 1 drink, Western Sizzlin is better since the buffet price is lower. From 3 drinks and up, Golden Corral is better.

The expression can be simplified as 2.09 × 10⁻⁹.

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

We have to evaluate (23)⁻³ . (34)⁻³.

We have a rule of exponent that,

aⁿ . bⁿ = (a . b)ⁿ

Applying the rule,

(23)⁻³ . (34)⁻³ = (23 × 34)⁻³

                      = 782⁻³

We have another rule of exponent that,

a⁻ⁿ = 1 / aⁿ

There are approximately 160 acres in a lot that is 1/2 mile by 1/2 mile.

To find the number of acres in a lot, you can use the following formula:

Number of acres = (length in feet) x (width in feet) / 43,560

First, convert the length and width from miles to feet. There are 5,280 feet in a mile, so:

Length in feet = 1/2 mile x 5,280 feet/mile = 2,640 feet
Width in feet = 1/2 mile x 5,280 feet/mile = 2,640 feet

Next, plug these values into the formula:

Number of acres = (2,640 feet) x (2,640 feet) / 43,560 = 174,240,000 / 43,560 = 160 acres

1. Milliliters, cubic centimeters and liters, are some of the volume units which are used to measure the space occupied by three-dimensional objects.

2. By definition:

-One milliliter (mL) is one thousandth of a liter (L). Therefore:

1 milliliter = 0.001 liters

- One cubic centimeter (cm³) is one thousandth of a liter (L). So:

1 cm³ = 0.001 liters

3. As you can see, 1 milliliter=1 cm³, therefore:

0.025 mL=0.025 cm³

4. To convert milliliters (mL) to liters (L), you have:

1 mL---------- 0.001 L

0.025 mL-----L=?

=(0.025)(0.001)/1

=2.5x10^-5 L

If l is the length of the brace, this is the same as  |7 - L| = 0.025 so option (A) will be correct.

An expression is a combination of some mathematical symbol such that arithmetic operator and variable such that all are constrained and create an equation.

In other meaning, expression is very useful to determine the end or root value of constraint.

For example 3x +5y

The constraint of expression is represented as = or <, >.

Given that,

Length of metal brace

l = 7 + 0.025

7 - l = -0.025

Now taking mode on both sides

|7 - L| = |-0.025|

|7 - L| = 0.025

Hence "If l is the length of the brace, this is the same as  |7 - L| = 0.025".
