Answer:

Step-by-step explanation:

Im not sure I can't see the picture.

Answer: Hence, the width of the path is 4 meters.

First we should find the area of the pool. Our width is 14 and our length is 18. In order to find the area, we must multiply these two numbers. 14 times 18 is 252. This means that the area of the pool is 252.

Since we know that one side of the pool is 18 and one side is 14, we can write out the equation below.

572= (18+2x)(14+2x)

The first thing we should do is combine like-terms.Our equation would now be as below.

x^2+16-80=0

Next we would take our quadratic equation- x=-b+-√b2-4ac/2a and fill it in with the numbers that we had in the first equation, our equation would be like below.  A=1   B=16   C=-80

x=-16+-√16^2-4* 1 * -80 /2 * 1

When then simplify our equation leaving us with x=-16+-√16^2-4*1(-80)/2 * 1, which broken down is x=-16+-√+-24/2.

Lastly we must subtract and add to receive our two answers.

One side is 4 and the other is -20. Since the width of the walk cannot not be a negative number, we know that the width of the path is 4 meters.

Hence, the width of the path is 4 meters.

Axj = bj, j=1,…,r.

To show that AX = B if and only if Axj = bj, j=1,…,r, we can start by recognizing that AX is an m×r matrix and B is an m×r matrix. Since the dimensions of these two matrices are the same, they are equal if and only if each corresponding element is equal.

Therefore, we can conclude that AX = B if and only if each corresponding element of AX is equal to its corresponding element in B. Mathematically, this is expressed as Axj = bj, j=1,…,r.

It is possible for each of the six quadratic equations to have at least one real root.

This is because the discriminant of a quadratic equation determines the nature of its roots. The discriminant is given by the formula: D = b² - 4ac.

If D > 0, the equation has two distinct real roots.
If D = 0, the equation has one real root (a double root).
If D < 0, the equation has no real roots (two complex roots).

In each of the six equations, the coefficients a, b, and c are non-zero real numbers. This means that the discriminant can be positive, zero, or negative, depending on the values of a, b, and c. Therefore, it is possible for each of the six equations to have at least one real root.

For example, consider the equation ax² + bx + c = 0. If b² > 4ac, then the equation has two distinct real roots. If b² = 4ac, then the equation has one real root (a double root). If b² < 4ac, then the equation has no real roots (two complex roots).

Similarly, the other five equations can also have at least one real root, depending on the values of the coefficients a, b, and c.

Using the addition method the solution to the system is (x,y) = (14/3, 7/3) and using the substitution method the solution to the system is (x,y) = (7,7).

Using the addition method, we can rearrange the equations so that one of the variables cancels out:

y=2x-7  ->  -2x + y = -7
y=4x-21  ->  -4x + y = -21

Now, we can add the two equations together to eliminate the y variable:

-2x + y = -7
-4x + y = -21
______________
-6x = -28

Next, we can solve for x:

x = 28/6 = 14/3

Now, we can substitute this value of x back into one of the original equations to find y:

y = 2x - 7 = 2(14/3) - 7 = 28/3 - 21/3 = 7/3

So the solution to the system is (x,y) = (14/3, 7/3).

Using the substitution method, we can substitute one equation into the other to eliminate one of the variables. For example, we can substitute the first equation, y=2x-7, into the second equation, y=4x-21:

2x-7 = 4x-21

Next, we can rearrange the equation to solve for x:

2x = 14
x = 7

Now, we can substitute this value of x back into one of the original equations to find y:

y = 2x - 7 = 2(7) - 7 = 7

So the solution to the system is (x,y) = (7,7).

In conclusion, we can solve the system y=2x-7 and y=4x-21 using either the addition method or the substitution method to find the solution (x,y).

here, we have,

The maximum number of beads the bracelet can have  = 12 beads

The fraction of green beads in the bracelet = 1/3

⇒ 1 bead in every 3 bead is GREEN.

⇒The minimum number of total beads = Number of (green+ Other) bead                                                           = 2 + 1  = 3

Now, the possible number of total beads the bracelet can have is

3, 4, 5 , 6, 7, 8, 9 ,10, 11 and 12.

If there are total 3 beads, the fraction representing the green bead  = 1/3

If there are total 6( =3 +3) beads, the fraction representing the green bead  

= 1 green bead in first 3 beads +  1  green bead in next 3 beads

=   2 green beads in total 6 beads

=   2/6

If there are total 9( = 3 +3 +3) beads, the fraction representing the green bead  = 3/9

If there are total 12( = 3 +  3 +3 +3) beads, the fraction representing the green bead  = 4/12

Hence, other fractions could represent the part of the beads on the bracelet that will be green are :1/3, 2/6, 3/9, 4/12.

The answer: no real solutions to this equation

To solve the equation, we need to find a common denominator for all of the fractions on the left side of the equation. The common denominator will be (y-2)(y-3), so we will multiply each fraction by the appropriate factor to get the common denominator.

[tex]y/y -2y+ 4/y-3 = 4/ y2-5y+6[/tex]

[tex]y(y-3)/(y-2)(y-3) - 2y(y-2)/(y-2)(y-3) + 4(y-2)/(y-2)(y-3) = 4/(y-2)(y-3)[/tex]

Now we can combine the fractions on the left side of the equation:

[tex](y2-3y-2y2+4y+4y-8)/(y-2)(y-3) = 4/(y-2)(y-3)[/tex]

Simplifying the numerator on the left side gives us:

[tex](-y2+5y-8)/(y-2)(y-3) = 4/(y-2)(y-3)[/tex]

Now we can cross-multiply and simplify:

[tex](-y2+5y-8) = 4[/tex]

[tex]-y2+5y-12 = 0[/tex]

To solve this equation, we can use the quadratic formula:

[tex]y=\left(-5\pm \sqrt{52-4\left(-1\right)\left(-12\right)}\right)[/tex]

[tex]y=\left(-5\pm \sqrt{25-48}\right)[/tex]

The estimated height of the child at delivery is represented by the y-intercept, which is 72.66.

We may use linear regression to construct an equation that represents the link between this child's height and age. The line of best fit for the supplied data is determined by linear regression, which can be written as:

Age (years) + b * m * Height (cm)

where m denotes the line's slope and b its y-intercept.

The equation that most closely matches the above data can be determined using a calculator or spreadsheet software as follows:

Age (years) + 72.66 Height (cm) = 6.087

Using the definition of a parallelogram in Euclid's first book, we can say that a non-perpendicular, unequal, non-bisecting diagonal produces either a trapezium or a rhombus if the opposite angles are equal, then it is a rhombus, and if the opposite angles are unequal, then it is a trapezium.

To use Euclid's first book to prove what specific quadrilaterals are produced by non-perpendicular, unequal, non-bisecting diagonals, start by considering Euclid's definitions of a parallelogram, a trapezium, and a rhombus.

In Euclid's first book, a parallelogram is defined as a quadrilateral which has two pairs of equal and parallel sides, while a trapezium is defined as a quadrilateral which has two pairs of opposite sides parallel, but with the other two sides unequal and non-parallel.

To find the total price, we need to add the tip and tax to the total bill amount.

First, we need to find the amount of the tip. To do this, we will multiply the total bill by 22% (or 0.22):

$45.65 x 0.22 = $10.04

This means the tip amount is $10.04.

Next, we need to find the amount of tax. To do this, we will multiply the total bill by 5% (or 0.05):

$45.65 x 0.05 = $2.28

This means the tax amount is $2.28.

Finally, we can find the total price by adding the total bill, tip, and tax together:

$45.65 + $10.04 + $2.28 = $57.97

Therefore, the total price is $57.97.
