479,001,600 necklaces can be made using 13 different beads.

We will be using 13 different beads in our necklace, and the arrangement of the beads is what distinguishes one necklace from another.

Additionally, the mirrored necklaces are different because we are unable to turn the necklaces around (the positions of the beads are mirrored)

We have 13 alternatives for the first bead, 12 options for the second, and so on.

if the product of the options for each choice results in a total number of combinations equal to 1, then we have:

Combinations of the form C=13*12*11*10*9*8*7*6*5*4*3*2*1

C = 6,227,020,800.

Now that the necklace may be rotated, a combination is possible.

A B C D E F G H I J K L M (Each letter corresponds to a certain bead)

is identical to other orders as

A through Z: m A B C D E F G H I J K L

With 13 rotations for each combination, the actual number of combinations is:

C/13 = 6,227,020,800/13 = 479,001,600

The value of h(f(3)) is 348.

What is simplification?

The method of simplifying something so that it is simpler to carry out or understand, or the product of such a method.

Here, we have

Given functions: f(x) = x³ + 8x, g(x) = √2x, h(x) = 7x-9

First, we will find f(3)

f(x) =  x³ + 8x

By simplification, we put x = 3 and get

f(3) = 27 + 24

f(3) = 51

Now, we find h(f(3)) and we get

h(x) = 7x-9

h(f(3)) = 7(51)-9

h(f(3)) = 357 - 9

h(f(3)) = 348

When two quantities are related in a linear relationship, then that arrangement is said to be in proportion.

Given that, a proportional relationship between gallons of paint and the area of the set.

The relation is :-

x (gallon of pain)  y (area)

The weight in ounces of paint which left after painting the wall is 114 ounces.

1 ounce is equivalent to 437.5 grains or 28.349 grams Abbreviation: oz. a unit of weight equivalent to one twelfth of a Troy or Pharmacists' pound; 1 ounce is equivalent to 480 grains or 31.103 grams. short for liquid ounce. a little part or sum.

Let x be how much paint in a strip. The aggregate sum of paint is 130+164+188=482. In the wake of painting the wall, the aggregate sum of paint is 482-4x. Since the aggregate sum in each tone is similar in the wake of getting done.

Then equation can be written as,

482 - 4x/3 = 130 -x

482 - 4x = 390 - 3x

x = 92

so, the paint left = 482-4x = 482 - 4(92) = 114.

Answer:

Step-by-step explanation:

5x + 1/3 = 1/3x - 9

5x - 1/3x + 1/3 = -9

5x * 3                           15x

14x/3 + 1/3 = -9

14x+1/3       = -9              (14x + 1 is ALL over 3)

Now multiply by 3 on both sides to cancel out the denominator since 3 is the denominator.

The time is required for a 5.75 mg sample of 51cr to decay to 0.700 mg is 99.4 days

What is decay constant?

Decay constant k = ln(2) / half life

= ln(2) / 27.8

= 0.024933 day⁻¹

For first order decay:

ln(M / M₀)  = -kt

where M is mass remaining at time t and  M₀ is initial mass.

ln(0.700/5/75) = -0.024933 * t

Time, t = 99.4 days

The temperature difference is 9 degrees.

b. Kiev is 1 degree. It gets 6 degrees warmer. Add 1+6=7

Kiev is 7 degrees at 6 pm.

The equation that relates the volume of water and the total ingredient volume is the one in option C, it is written as:

t = 4*w

So we know that the volume of water before mixing is 25% of the total ingredient volume.

So if we define the variables:

Then we know that w is equal to the 25% of t.

Then the relation can be written as:

w = (25%/100%)*t

Where we divide the percentage by 100% so we write a decimal number instead of a percentage.

Now we can simply it so we get:

w =  (25%/100%)*t

w = 0.25*t

Now we can isolate t to get:

t = (1/0.25)*w

t = 4*w

So the correct option is C.

The symbolic equation for the location of the center of mass of 3 beads is [tex]x_{cm}[/tex] = m1d1 + m2 (d1 + d2) + m3 ( d1+d2+d3)/ m1 + m2 + m3

Mass of 1st bead = m1 = 22 g

Mass of the 2nd bead = m2 = 12 g

Mass of the 3rd bead = m3 = 51 g

Distance of the 1st bead from left end of the rod = d1 = 1.5 cm

Distance of the 2nd bead from the first bead = d2 = 1.9 cm

Distance of the 3rd bead from the second bead = d3 = 4.5 cm

Location of the center of mass of the three beads relative to the left end of the rod = xcm

We want to find the center of mass relative to the left end of the rod therefore we will need the distances of each bead from the left end of the rod.

Distance of the first bead from the left end of the rod = x1

x1 = d1

Distance of the second bead from the left end of the rod = x2

x2 = d1 + d2

Distance of the third bead from the left end of the rod = x3

x3 = d1 + d2 + d3

[tex]x_{cm}[/tex] = m1 x1 + m2 x2 + m3 x3 / m1 + m2 + m3

[tex]x_{cm}[/tex]= m1(d1) + m2(dı + d2) + m3(d1 + d2 +d3)/ m1 + m2 + m3

[tex]x_{cm}[/tex] = m1d1 + m2 (d1 + d2) + m3 ( d1+d2+d3)/ m1 + m2 + m3

Substituting the values to get a numerical answer,

[tex]x_{cm}[/tex] = (22)(1.5) + (12)(1.5 +1.9) + (51)(1.5 +1.9 +4.5) 22 + 12 + 51

xcm = 5.61 cm

Location of the center of mass of the three beads relative to the center bead = x

Distance of the first bead from the center bead (second bead) = x4

x4 = -d2 (Negative as it is to the left of the second bead)

Distance of the second bead from the center bead (second bead) = x5 = 0 cm

Distance of the third bead from the center bead (second bead) = x6

x6 = d3

x = m1 x4 + m2 x5 + m3 x6/ m1 + m2 + m3

x = m1 ( - d2) + m2 (0) + m3 (d3) / m1 + m2 + m3

x = - m1 d2 + 0 + m3d3 / m1 + m2 + m3

x = m3d3 - m1 d2 / m1 + m2 + m3

Substituting the values to get a numerical answer,

x= (51) (4.5) - (22)(1.9)/22 + 12 + 51
