Applying mathematical operations, the greatest number of necklaces Georgia can make is 26.

The total number of beads available for making bracelets and necklaces is an addition operation between the beginning inventory of beads and the additional units purchased.

A subtraction operation is performed to determine the remainder after making bracelets.

Finally, a division operation determines the greatest number of necklaces to make.

The beginning inventory of beads = 322

The units purchased = 38 beads

The total number of beads that Georgia has = 360 (322 + 38)

The number of beads required to make bracelets = 120

The remainder after making bracelets = 240 (360 - 120)

The number of beads required for each necklace = 9

The greatest number of necklaces Georgia can make = 26 (240 ÷ 9)

Answer:

x = 5√2, x = 3√2

Step-by-step explanation:

Question 1:

Using the 30-60-90 triangle properties, YX = WX /√3.

YX = 5√3 /√3 = 5.

Using the 45-45-90 triangle properties, x = YX *√2.

x = 5 *√2 = 5√2.

Question 2:

Using the 45-45-90 triangle properties, BC = AB *√2.

BC = 6 *√2 = 6√2.

Using the 30-60-90 triangle properties, x = BC / 2.

x = 6√2 / 2 = 3√2.

Answer:

Time = Distance / Speed

Time is taken from home to park = d / 10

Abel cycled back from the park to his home at an average speed of 8 km/h. The time taken for this part of the journey can be calculated using the same formula:

Time = Distance / Speed

Time is taken from park to home = d / 8

According to the given information, the total time taken for the whole journey is 1 1/5 hours, which is equivalent to 6/5 hours.

Total time is taken = Time from home to park + Time from park to home

6/5 = d/10 + d/8

To simplify the equation, let's find the least common multiple (LCM) of 10 and 8, which is 40:

(6/5) * 40 = (d/10) * 40 + (d/8) * 40

48 = 4d + 5d

48 = 9d

d = 48/9

d = 16/3 km

Now, to find the time taken from the park to Abel's home, we substitute the distance value:

Time from park to home = (16/3) / 8

Time from park to home = (16/3) * (1/8)

Time from park to home = 16/24

Time from park to home = 2/3 hour

Since 2/3 of an hour is equal to 40 minutes, Abel took 40 minutes to cycle from the park to his home.

Therefore, Abel took 40 minutes (or 2/3 of an hour) to cycle from the park to his home.

The distance between the two lines is about 6/√17 units, which is approximately 1.46 units

To find the distance between two parallel lines, we need to find the length of the perpendicular segment that connects them.

Both lines have the same slope (4), so they are parallel and never intersect.

The shortest distance between them will be the perpendicular distance between any point on one line and the other line.

Let's choose a point on the first line, say (0, -1), and find the perpendicular distance from this point to the second line.

We can use the formula for the distance between a point (x₁, y₁) and a line in slope-intercept form y = mx + b:

Distance = |m(x₁) - y₁+ b| /√m² + 1

Plugging in the values for the second line, we get:

Distance = |4(0) - (-1) + 5| / √4² + 1

Distance = 6 / sqrt(17)

Therefore, the distance between the two lines is about 6/√17 units, which is approximately 1.46 units

Step-by-step Explanation:

To create an equation to predict the number of seats in any row, we need to start by defining a few variables:

Let's call the number of seats in the first row "a".

Let's call the number of additional seats in each row after the first row "d".

Since we know that each row has 6 more seats than the previous row, we can set d equal to 6:

d = 6

We also know that the first row has 11 seats, so we can set a equal to 11:

a = 11

To find the number of seats in any row, we can use the following formula:

number of seats in a given row = a + (n - 1) * d

Where "n" is the number of the row we are interested in.

Using this formula, we can find the number of seats in row 18:

number of seats in row 18 = 11 + (18 - 1) * 6

= 11 + 102

= 113

Therefore, there are 113 seats in row 18.

The volume of the new object is approximately 439.3 cubic inches

To find the volume of the new object, we need to first know the volume of the prism before the cylinder is removed hence we do this:

The volume of a cylinder: = πr²h

where:

r = radius

h  = height

Note that the volume of a rectangular prism is :  = lwh

l = length

w = width

h = height

Assumption: In the above case, we will  assume that the dimensions of the rectangular prism because the cylinder can be cut out from the center of one of the faces.

Hence the length and width of the prism will be taken to be twice the radius of the cylinder, that is 16 inches, and the height will be taken to be same as the radius of the cylinder, that ia 8 inches.

So  V_prism = lwh

 = 16 × 16 × 8

= 2048 cubic inches

V_cylinder = πr²h

= π × 8² × 8

= 512 π cubic inches

Hence To get  the volume of the new object, we need to subtract the volume of the cylinder from the volume of the prism:

V_new = V_prism - V_cylinder

= 2048 - 512π

= 2048  - 1608.70

= 439.3 cubic inches

Let's say there are $v$ varsity players and $j$ JV players.

The problem tells us that 2/3 of the varsity players are partnered with 3/5 of the JV players. So the number of varsity players partnered with a JV player is:

$\sf\implies\:(2/3)v$

And the number of JV players partnered with a varsity player is:

$\sf\implies\:(3/5)j$

Since these two numbers represent the same group of paired players, they must be equal:

$\sf\implies\:(2/3)v = (3/5)j$

To find the fraction of players who are partnered, we can divide the total number of paired players by the total number of players:

$\implies\:\frac{(2/3)v}{v} = \frac{2}{3}$ of the varsity players are paired

$\implies\:{\sf{\frac{(3/5)j}{j}} = \frac{3}{5}}$ of the JV players are paired

So the total fraction of players who are paired is:

$\sf\implies\:\frac{2}{3} + \frac{3}{5} - \frac{2}{15}$ (since some players will be counted in both fractions)

Simplifying:

$\sf\implies\:\frac{10}{15} + \frac{9}{15} - \frac{2}{15} = \frac{17}{15}$

Therefore, the fraction of players who are partnered for training is $\frac{17}{15}$, which is greater than 1. This means that the problem may have been set up incorrectly, or there may be additional information missing.

For the given function the value of f(x) when x = 2 is 0.5, option (d) is correct.

The given function f(x) = 2/x² represents a hyperbolic curve with a vertical asymptote at x=0 and a horizontal asymptote at y=0. As x approaches infinity or negative infinity, the value of the function approaches 0.

The given function is:

f(x) = 2 ÷ x²

We are asked to find the value of f(x) when x = 2.

Substituting x = 2, we get:

f(2) = 2 ÷ 2²

= 2 ÷ 4

= 1/2

= 0.5

Alternatively, we can use the fact that 2² = 4 and simplify the expression as follows:

f(x) = 2 ÷ x²

= 2 ÷ 4

= 1/2

Then, substituting x = 2, we get the same result:

f(2) = 1/2

f = 0.5

The result of the synthetic division is:4x⁵+17x⁴+14x³-3x²+2 = (4x⁴ + 5x³ - x²) (x + 3) + 56

what is synthetic division ?

Synthetic division is a simplified method of dividing a polynomial by a linear factor. It is commonly used in algebra to find the quotient and remainder when dividing a polynomial by a linear factor of the form (x-a).

In the given question,

To use synthetic division to rewrite the fraction, we first set up the problem like this:

   -3 | 4    17    14    -3    0    2

       |     -12    -15    3   0

       +----------------------------------

          4     5    -1     0    0    2

The coefficients of the polynomial are written in descending order of powers of x, with any missing terms replaced by zeros. The divisor, x + 3, is written on the left, and the first coefficient of the polynomial is written on the top of the vertical line.

We then proceed to perform synthetic division as follows:

Bring down the first coefficient, which is 4, and write it under the horizontal line.

Multiply the divisor, -3, by the number we just brought down, which gives -12. Write this number under the next coefficient, 17.

Add the two numbers, 17 and -12, to get 5. Write this number under the next coefficient, 14.

Multiply the divisor, -3, by 5, which gives -15. Write this number under the next coefficient, -3.

Add the two numbers, -3 and -15, to get -18. Write this number under the next coefficient, 0.

Multiply the divisor, -3, by -18, which gives 54. Write this number under the next coefficient, 2.

Add the two numbers, 2 and 54, to get 56. This is the remainder, which we write above the divisor.

The result of the synthetic division is:

4x⁵+17x⁴+14x³-3x²+2 = (4x^4 + 5x³ - x²) (x + 3) + 56

Therefore, we have rewritten the fraction in the desired form:

4x⁵+17x⁴+14x³-3x²+2

---------------------- = 4x⁴ + 5x³ - x² + 56/(x+3)
