Using the Factor Theorem, the equation of h(x) is given as follows:

h(x) = -2(x³ - 2x² - 5x + 6)

The Factor Theorem states that a polynomial function with roots [tex]x_1, x_2, \codts, x_n[/tex] is given by:

[tex]f(x) = a(x - x_1)(x - x_2) \cdots (x - x_n)[/tex]

In which a is the leading coefficient.

Looking at the table, considering the values of x when h(x) = 0, the roots of h(x) are given as follows:

[tex]x_1 = -2, x_2 = 1, x_3 = 3[/tex]

Then the rule is:

h(x) = a(x + 2)(x - 1)(x - 3)

h(x) = a(x² + x - 2)(x - 3)

h(x) = a(x³ - 2x² - 5x + 6)

The h-intercept is of -12, as when x = 0, h = -12, hence this is used to find a as follows:

6a = -12

a = -12/6

a = -2.

Hence the function is given by:

h(x) = -2(x³ - 2x² - 5x + 6)

The statement that "σ(n) < 2n holds true for all n of the form n = p²" has been proved.

Let p be any prime number, and let σ(n) be the sum of all positive divisors of the integer n.

As p is a prime number, and 2 is the smallest prime number, so, p[tex]\geq[/tex]2

So, the positive divisors of the integer n are: 1,p,p².

As σ(n) represents the sum of all positive divisors of the integer n.

σ(n)=1+p+p²

In order to prove that σ(n) < 2n,for all n of the form n = p².

1+p+p²<2p²

p²-p-1>0

It is know that, p[tex]\geq[/tex]2.

So, p²-p-1[tex]\geq[/tex]1

Answer:

Area = 33 inches squared

Step-by-step explanation:

The formula for the area of a kite is:

Area = ½ × (d)1 × (d)2

To find the first diagonal (d1):

d1 = 7 in + 4 in = 11 in

To find the second diagonal (d2):

The triangles on the right of the kite must be 3 4 5 triangle since it is a right triangle with a hypotenuse of 5 and a side of 4, we know half of a diagonal would be 3 inches.

d2 = 3 in + 3 in = 6 in

Now we can plug the diagonals into the area formula.

Area = ½ × 11 × 6 = 33 inches squared

Answer: A = 33 in²

Step-by-step explanation:

Given information:

Longer side = 7 in

Shorter side = 4 in

Shorter Hypotenuse = 5 in

Given formula:

A = (1/2) × (d₁) × (d₂)

Please refer to the attachment below for a graphical understanding

Determine the length of the shorter side (vertical) through the Pythagorean theorem

a² + b² = c² (Pythagorean theorem)

(4)² + b² = (5)² (Substitute values into the equation)

16 + b² = 25

b² = 25 - 16

b² = 9

b = 3  or b = -3 (rej)

Substitute values into the given formula

A = (1/2) × d₁ × d₂

A = (1/2) × (7 + 4) × (3 + 3)

Simplify values in the parenthesis

A = (1/2) × 11 × 6

A polar curve exists as a form constructed utilizing the polar coordinate system. Polar curves exists determined by points that exist at a variable distance from the origin (the pole) depending on the angle calculated off the positive x-axis.

The polar graph can be said to contain a symmetry about the polar axis which indicates that theta or θ exists equivalent to 0.

This exists because the graph is symmetric about the x-axis. This indicates that all the lines of symmetry can be seen intersecting the graph at x = 0. This demonstrates that there exists indeed symmetry in the polar graph.

The value of x which S(x) is a global minimum is x = 1/2

From the question, we have:

This means that:

S(x) = 1/x + 4x^2

From the question, we understand that x is a positive number.

This means that the domain of x is x > 0

As a notation, we have (0, ∞)

Recall that:

S(x) = 1/x + 4x^2

Differentiate the function

S'(x) = -1/x^2 + 8x

Set to 0

-1/x^2 + 8x = 0

Multiply through by x^2

-1 + 8x^3 = 0

Add 1 to both sides

8x^3 = 1

Divide by 8

x^3 = 1/8

Take the cube root of both sides

x = 1/2

To prove the point is a global minimum, we have:

S'(x) = -1/x^2 + 8x

Determine the second derivative

S''(x) = 2/x^3 + 8

Set x = 1/2

S''(x) = 2/(1/2)^3 + 8

Evaluate the exponent

S''(x) = 2/1/8 + 8

Evaluate the quotient

S''(x) = 16 + 8

Evaluate the sum

S''(x) = 24

Because S'' is positive, then the single critical point is a global minimum

A simultaneous equation is a set of equations that has to be solved in relation to each other at the same time. Thus the required number of stamps are:

4¢ stamps = 16

5¢ stamps = 7

A simultaneous equation is a set of equations that has to be solved in relation to each other at the same time. This process is required so as to determine the values of two unknowns e.g x and y.

From the given question, let the number of 4¢ stamps be represented by n, and that of the 9¢ stamp be represented by m.

So that,

n + m = 23 ............ 1

But 100¢ = $1, so that;

4¢ = x

x = [tex]\frac{4}{100}[/tex]

  = $0.04

also,

9¢ = x

x = [tex]\frac{9}{100}[/tex]

  = $0.09

Thus, we have;

0.04n + 0.09m = 1.27 ......... 2

From equation 1, make n the subject of the formula, such that;

n = 23 - m ........... 3

Substitute equation 3 into equation 2

0.04(23 - m) + 0.09m = 1.27

0.92 - 0.04m + 0.09m = 1.27

collect like terms to have;

0.05m = 1.27 - 0.92

          = 0.35

m = [tex]\frac{0.35}{0.05}[/tex]

m = 7

Now substitute the value of m into equation 3

n = 23 - m ........... 3

  = 23 - 7

n = 16

Therefore the number of 4¢ stamps is 16, while that of the 5¢ stamps is 7.

Answer:

7,647.4?

Step-by-step explanation:

Using the law of cosines and sines, the measure of angle B is: 38.4°.

Law of cosines is: c = √[a² + b² ﹣ 2ab(cos C)]

Law of sines is: sin A/a = sin B/b = sin C/c

Use the law of cosines to find c:

c = √[12² + 18² ﹣ 2(12)(18)(cos 117)]

c ≈ 25.8

Use the law of sines to find angle B:

sin B/b = sin C/c

sin B/18 = sin 117/25.8

sin B = (sin 117 × 18)/25.8

sin B = 0.6216

B = sin^(-1)(0.6216)

The probability that exactly 7 are men out of 10 sports car owners who are randomly selected is 0.215 given that 60% of people who purchase sports cars are men. This can be obtained by using binomial distribution formula.

This question can be solved using binomial distribution formula.

The formula for binomial distribution is the following,

P(X) = ⁿCₓ pˣ qⁿ⁻ˣ

where,

n = number of trials(or the number being sampled)

x = number of success desired

p = probability of getting a success in one trial

q = 1 - p = probability of getting a failure in one trial

Here in the question it is given that,

⇒ 60% of people who purchase sports cars are men

This statements clearly means that probability of men purchase sports cars is 60%.

⇒ P(men purchasers) = p = 60% = 0.6

From this we can find the probability of women who purchase sports cars,

⇒ P(women purchasers) = q = 1 - p = 1 - 0.6 = 0.4

So we can find the probability that exactly 7 are men out of 10 sports car owners who are randomly selected

It is a binomial case with n = 10

By using the  formula for binomial distribution we get,

P(X = 7) = ¹⁰C₇ × 0.6⁷ × 0.4³

P(X = 7) = 120 × 0.0279936 × 0.064

P(X = 7) = 0.21499

P(X = 7) = 0.215

Hence the probability that exactly 7 are men out of 10 sports car owners who are randomly selected is 0.215 given that 60% of people who purchase sports cars are men.

Step-by-step explanation:

8x + 4y = 7 → (1)

6x - 8y = 41 → (2)

multiplying (1) by 2 and adding to (2) will eliminate y

16x + 8y = 14 → (3)

add (2) and (3) term by term to eliminate y

22x + 0 = 55

22x = 55 ( divide both sides by 22 )

x = [tex]\frac{55}{22}[/tex] = [tex]\frac{5}{2}[/tex]

substitute this value into either of the 2 equations and solve for y

substituting into (1)

8([tex]\frac{5}{2}[/tex] ) + 4y = 7

20 + 4y = 7 ( subtract 20 from both sides )

4y = - 13 ( divide both sides by 4 )

To find the solutions to the given quadratic equation, factor the equation.

To factor a quadratic in the form [tex]ax^2+bx+c[/tex], find two numbers that multiply to ac and sum to b.

[tex]\implies ac=9 \cdot 1=9[/tex]

[tex]\implies b=6[/tex]

Therefore, the two numbers are: 3 and 3.

Rewrite the middle term as the sum of these two numbers:

[tex]\implies 9x^2+3x+3x+1=0[/tex]

Factor the first two terms and the last two terms separately:

[tex]\implies 3x(3x+1)+1(3x+1)=0[/tex]

Factor out the common term (3x + 1):

[tex]\implies (3x+1)(3x+1)=0[/tex]

Therefore:

[tex]\implies(3x+1)^2=0[/tex]

This means that the curve has one root with multiplicity 2. So the curve touches the x-axis and bounces off the axis at one point. (See attached graph).

Step-by-step explanation:

solve for the one letter that gets talked about the most

which is w or width

width = w

length = 3 + w

2 inch border means

width = w + 2

length = 3 + w + 2

area = length times width

area = ( 3 + w + 2 ) times (w + 2 )

108 = ( 3 + w + 2 ) times (w + 2 )

108 = ( w + 5 ) times (w + 2 )

( w + 5 ) times (w + 2 ) = 108

w^2 + 7w +10 = 108

w^2 + 7w - 98 = 0

going to make w = x

x^2+7x-98=0

(x-7)(x+14)

x = 7

x = -14
