The number of quadrilaterals that can be formed with the vertices of a regular pentagon is given by:

5.

The number of vertices for each polygon is given as follows:

Hence, to build the quadrilaterals, four vertices are taken from the set of five vertices of the pentagon.

The formula to be used is given as follows:

The order of the vertices is not relevant, hence the combination formula is used, given as follows:

[tex]C_{n,x} = \frac{n!}{x!(n - x)!}[/tex]

Which gives the number of different combinations of x elements from a set of n elements.

Hence, in the context of this problem, the number of quadrilaterals is obtained as follows:

[tex]C_{5,4} = \frac{5!}{4!1!} = 5[/tex]

The problem asks for how many quadrilaterals can be formed with the vertices of a regular pentagon.

Answer:

P(x) = 0.7 [tex]x^{4}[/tex] - 4.9x³ + 5.6x² + 11.2x

Step-by-step explanation:

given a polynomial with roots x = a and x = b , then the factors are

(x - a) and (x - b)

If x = a is of multiplicity 2 then factor is (x - a)²

the polynomial is then the product of the factors

p(x) = a(x - a)(x - b) ← a is a multiplier

give x = 4 is a root with multiplicity 2 then (x - 4)² is the factor

x = 0 has factor (x - 0) , that is x

x = - 1 has factor (x - (- 1)) , that is (x + 1)

the polynomial is then the product of the factors

P(x) = ax(x + 1)(x - 4)² ← expand squared factor using FOIL

       = ax(x + 1)(x² - 8x + 16)

       = a(x² + x)(x² - 8x + 16) ← distribute

       = a([tex]x^{4}[/tex] - 8x³ + 16x² + x³ - 8x² + 16x)

      = a([tex]x^{4}[/tex] - 7x³ + 8x² + 16x)

to find a substitute (5, 21 ) into P(x)

21 = a([tex]5^{4}[/tex] - 7(5)³ + 8(5)² + 16(5))

21 = a(625 - 875 + 200 + 80)

21 = 30a ( divide both sides by 30 )

0.7 = a

then

P(x) = 0.7([tex]x^{4}[/tex] - 7x³ + 8x² + 16x) ← distribute parenthesis

P(x) = 0.7[tex]x^{4}[/tex] - 4.9x³ + 5.6x² + 11.2x

The cost to rent chair is $1.5  and table is $8.5  .

In the question ,

it is given that

the cost to rent 12 chairs and 2 tables [tex]=[/tex] $35

and the cost to rent 3 chairs and 5 tables  [tex]=[/tex] $47

let the cost for 1 chair ne "c"

and let the cost for 1 table = "t"

So , according to the question ,

the equations are

12c + 2t = 35      ....equation(1)

3c + 5t = 47         ....equation (2)

On multiply equation (2) by 4 and then subtracting equation (1) from it ,

we get

(12c + 20t) - (12c + 2t) = 188 - 35

12c + 20t - 12c -2t = 153

18t = 153

t = 153/18

t = 8.5

and 12c + 2(8.5) = 35

12c + 17 = 35

12c = 18

c = 18/12

c = 1.5

The probability that the sample proportion will differ from the population proportion by more than 3% is 0.8948

The requirement to solve the probability between z-values is to know that the probability between the z-values is the difference between the probability of the greatest z-value and the lowest z-value.

In this case, the sample proportion:

= ✓[p(1 - p)/n]

= ✓(0.13 × 0.87)/329

= 0.01854.

The probability will be:

P(-0.03 / 0.01854) < z < (0.03 / 0.01854)

P(-1.62 < z < 1.62)

The standard forms of the equation of a line are:

Slope-intercept form:

y = mx + c

Where m indicates the slope of the line and c is the y-intercept

Intercept form:

x/a + y/b = 1

General form of the equation of the straight line, i.e. Ax+By+C = 0

x/(-C/A) + y/(-C/B) = 1

where a = -C/A and b = – C/B

Normal form:

The equation of the line whose length of the normal from the origin is p and the angle made by the normal with the positive x-axis is given by α is given by:

x cos α+y sin α = p

Given,

Point = (6,-2) = (x2,y2)

Equation of line = y+2=-2/5(x-10)

General equation of the line = y - y1 = m ( x-x1 )

After comparing we get,

Slope of the given line = -2/5

As we know both the lines are perpendicular to each other so, product of their slopes must be equal to -1.

m1 × m2 = -1

-2/5 × m2 = -1

We get m2 = 5/2

So the equation of the line having slope  5/2 and passing through  (6,-2) is:

y - y2 = m2 ( x-x2 )

y -(-2) = 5/2 (x - 6)

y + 2 = 5/2 (x - 6)

Hence, we get equation of the line as y + 2 = 5/2 (x - 6) .

The graph of this proportional relationship would look like this: A line passes through the point (0, 0) and continues through the point (14, 7).

In Mathematics, a graph simply refers a type of chart that is typically used to graphically represent data points on both the horizontal and vertical lines of a cartesian coordinate, which are the x-coordinate (x-axis) and y-coordinate (y-axis).

Generally speaking, the graph of any proportional relationship is always characterized by a straight line with the data points passing through the origin (0, 0) because as the values on the x-coordinate (x-axis) increases or decreases, the values on the y-coordinate (y-axis) increases or decreases simultaneously.

By critically observing graph of this proportional relationship (see attachment), we can logically deduce that it passes through both points (0, 0) and (14, 7).

Step-by-step explanation:

You want the next two numbers in the sequence beginning 6, 24, 60, 120, 210, ....

When attempting to identify a sequence it is often useful to look at the differences between terms, then at the differences of those, and so on. If The differences at some level are constant, that level tells you the degree of the polynomial that will describe the sequence. If they have a common ratio, then the sequence will be based on an exponential function.

1st differences: 18, 36, 60, 90

2nd differences: 18, 24, 30

3rd differences: 6, 6 . . . . . . . . constant, indicating a cubic function

We can go to the trouble to write four equations in the four coefficients of the cubic describing this sequence, or we can let suitable technology find it for us. The attachment shows a graphing calculator solution for the coefficients. The 10^-14 value for the 'd' coefficient is effectively 0. This value is due to the inexact representation of numbers in the floating point arithmetic used by the calculator.

The equation of the n-th term a[n] is ...

  a[n] = n³ +3n² +2n

The 95% confidence interval for the distribution of the difference of proportions, using the z-distribution, is given as follows:

(0.11, 0.146).

The first step is finding the proportion and standard error for each sample, as follows:

For the distribution of differences, the mean and the standard error are given as follows:

The z-distribution is used as we are working with proportions, hence the bounds of the interval are given as follows:

p ± zs.

The critical value for a 95% confidence interval with the z-distribution is of z = 1.96.

Hence the lower bound of the interval is:

0.128 - 1.96 x 0.0092 = 0.11.

The upper bound of the interval is:

0.128 + 1.96 x 0.0092 = 0.146.

Step-by-step explanation:

The rate at which the tip of the woman's shadow is moving, found by making use of the relationships between similar triangle and differentiation is 10 ft/s

Similar triangles are triangle in which all three sides of one proportional to three sides of the other triangle

Height of the woman = 6 ft.

The speed with which the woman walks towards the streetlight = 8 ft/s
The length of the shadow of the woman

Height of the street light = 30 ft.

Let a represent the horizontal distance from the woman to the street light, and let b represent the horizontal distance from the woman to the tip of her shadow, from the similar triangles formed by the shadow, we have;

[tex]\dfrac{30}{x+y} =\dfrac{6}{y}[/tex]
Which gives;

[tex]y = \dfrac{x}{4}[/tex]

The length of the tip of the woman's shadow to the street light, l, in terms of x is therefore;

[tex]l =x + y = x + \dfrac{x}{4} = \dfrac{5\cdot x}{4}[/tex]

[tex]\dfrac{dx}{dt} = 8[/tex]

Therefore, dx = 8·dt

x(t) = 8·t

Writing the function for the l in terms of time t gives;

[tex]l = \dfrac{5\cdot x}{4}[/tex]

[tex]l = \dfrac{5\times 8\cdot t}{4} = \dfrac{40\cdot t}{4} = 10\cdot t[/tex]

The speed at which the tip of the shadow is moving,

[tex]\dfrac{dl}{dt} = \dfrac{d}{dt} \left (10\cdot t ) = 10[/tex]

The speed of the shadow dl/dx = 10 ft./s
