Step-by-step explanation:

You can read f(0) = 3/2 from the table. The slope is 1/2, so f(4) will be 1 more than f(2): f(4) = 7/2.

a) The two types of parallel lines in hyperbolic geometry are ultra-parallel lines and limit-parallel lines.

b) The angle opposite the common base in a Saccheri quadrilateral is a right angle, while the other two angles are congruent.

c) The formula for the area of a convex hyperbolic polygon is A = E/K, where A is the area, E is the excess of angles, and K is the curvature.

a) In hyperbolic geometry, there are two types of parallel lines: ultra-parallel lines and limit-parallel lines.

Ultra-parallel lines are lines that do not intersect and are always equidistant from each other. They have no common perpendiculars and provide an example of "diverging" parallel lines in hyperbolic geometry.

Limit-parallel lines, on the other hand, are lines that do not intersect and approach a common limit point on the hyperbolic plane. They are considered "converging" parallel lines in hyperbolic geometry.

b) In a Saccheri quadrilateral, the interesting aspect is that the angle opposite the common base is a right angle, and the other two angles are congruent. This characteristic makes the Saccheri quadrilateral a key tool in proving the consistency of hyperbolic geometry and understanding its properties.

c) The formula for calculating the area of a convex hyperbolic polygon is given by the Gauss-Bonnet theorem. It states that the area (A) of a convex hyperbolic polygon is equal to the excess of its angles (E) multiplied by a constant called the curvature (K):

A = E/K

Here, the excess of angles is the sum of the interior angles of the polygon minus (n-2)π, where n is the number of sides of the polygon. The curvature depends on the specific geometry being considered (e.g., positive for spherical geometry, negative for hyperbolic geometry).

Step-by-step explanation:

There were 59.2 million enterprise IM accounts in 2006 and the expected number of enterprise IM accounts in 2009 was 119.89 million.

(a) To find the number of enterprise IM accounts in 2006, we need to evaluate

N(t) at t = 0: N(0) = 2.97(0)^2 + 11.32(0) + 59.2

N(0) = 0 + 0 + 59.2

N(0) = 59.2 million

So, there were 59.2 million enterprise IM accounts in 2006.

(b) To find the expected number of enterprise IM accounts in 2009, we need to evaluate

N(t) at t = 3 (since 2009 corresponds to t = 3): N(3) = 2.97(3)^2 + 11.32(3) + 59.2

N(3) = 2.97(9) + 33.96 + 59.2

N(3) = 26.73 + 33.96 + 59.2

N(3) = 119.89 million

So, the expected number of enterprise IM accounts in 2009 was 119.89 million.

The expression for the cubic function f is -5x^3 + 20x^2 - 25x.

To find an expression for a cubic function f(x) given specific values, we can start by using the general form of a cubic function: f(x) = ax^3 + bx^2 + cx + d.

We are given three points on the graph of the function: (5, 300), (-5, 0), and (0, 0), as well as (6, 0) which gives us a fourth point.

Substituting the x and y values into the equation, we get the following system of equations:

For point (5, 300):

300 = a(5^3) + b(5^2) + c(5) + d

For point (-5, 0):

0 = a(-5^3) + b(-5^2) + c(-5) + d

For point (0, 0):

0 = a(0^3) + b(0^2) + c(0) + d

For point (6, 0):

0 = a(6^3) + b(6^2) + c(6) + d

Simplifying these equations, we obtain a system of linear equations in terms of a, b, c, and d. Solving this system will give us the coefficients for the cubic function.

After solving the system, we obtain the expression for the cubic function:

f(x) = -5x^3 + 20x^2 - 25x

The inverse of a function can be found by swapping the numbers in each ordered pair of the function.

When you have a function with ordered pairs, the inverse of that function can be found by reversing the order of the numbers within each pair. In other words, if you have a function f(x) with ordered pairs (a, b), the inverse function, f^ (-1) (x), will have ordered pairs (b, a). This process essentially switches the input and output values of the original function.

To find the inverse of a function, simply swap the numbers in each ordered pair, resulting in the ordered pairs for the inverse function.

Classifying Polynomials

Polynomials can be classified two different ways - by the number of terms and by their degree.

1. Number of terms.

A monomial has just one term. For example, 4x2 .Remember that a term contains both the variable(s) and its coefficient (the number in front of it.) So the is just one term.

A binomial has two terms. For example: 5x2 -4x

A trinomial has three terms. For example: 3y2+5y-2

Any polynomial with four or more terms is just called a polynomial. For example: 2y5+ 7y3- 5y2+9y-2

Practice classifying these polynomials by the number of terms:

1. 5y

2. 3x2-3x+1

3. 5y-10

4. 8xy

5. 3x4+x2-5x+9

Answers: 1) Monomial 2) Trinomial 3) Binomial 4) Monomial 5) Polynomial

2. Degree. The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s).

Examples:

5x2-2x+1 The highest exponent is the 2 so this is a 2nd degree trinomial.

3x4+4x2The highest exponent is the 4 so this is a 4th degree binomial.

8x-1 While it appears there is no exponent, the x has an understood exponent of 1; therefore, this is a 1st degree binomial.

5 There is no variable at all. Therefore, this is a 0 degree monomial. It is 0 degree because x0=1. So technically, 5 could be written as 5x0.

3x2y5 Since both variables are part of the same term, we must add their exponents together to determine the degree. 2+5=7 so this is a 7th degree monomial.

Classify these polynomials by their degree.

10.20 regular cost

Step-by-step explanation:

8.50 x 6 = 51 total

51/5 = 10.20

Although part of your question is missing, you might be referring to this full question: If the 1st person saves 1/4 of total, 2nd person saves 2/3 of total, and 3rd person saves 1/10, which fraction left to pay for the birthday party?

The fraction left to pay for the birthday party is 17/30.

The calculation is as follows:

1 * 1/4 = 1/4 … (1)

1/4 * 2/3 = 2/12 … (2)

2/12 * 1/10 = 2/120 … (3)

Fraction left to pay:

= 1 - (1/4 + 2/12 + 2/120)

= 1 - (30/120 + 20/120 + 2/120)

= 1 - (52/120)

= 1 - 13/30

= 30/30 - 13/30

= 17/30

Thus, the fraction left to pay for the birthday party is 17/30.

A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, where the numerator is divided by the denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. In a proper fraction, the numerator is less than the denominator.

The value of x + 3x - 4.2 when x = 5 is 15.8 and the first step is to substitute the value of x into the expression.

The first step when evaluating x + 3x - 4.2 when x = 5 is to substitute the value of x into the expression.

So, we substitute x = 5 into the expression:

5 + 3(5) - 4.2

Now, we can simplify the expression by performing the operations in order:

5 + 15 - 4.2

The first step is to perform the multiplication:

5 + 15 = 20

Now, we can subtract 4.2 from 20:

20 - 4.2 = 15.8

Therefore, the value of x + 3x - 4.2 when x = 5 is 15.8.

Step-by-step explanation:

Note we are told that d = -2x² + 10, where d is distance (in feet) and x is time (in seconds).

After how many seconds is the skateboarder 1 ft from the bottom of the hill? => What is x when d=1?

To do this, sub 1 in for d and solve for x:

d = -2x² + 10

1 = -2x² + 10

-9 = -2x²

4.5 = x²

x = \(\sqrt{4.5}\) ≈ 2.12132

As per the given commission, the sales price of the property is $405,000.

To do this, we need to break down the commission earned by the agent into two parts: the commission earned on the first $300,000 and the commission earned on the remaining amount. The commission earned on the first $300,000 can be calculated as:

Commission on first $300,000 = 6% of $300,000

Commission on first $300,000 = 0.06 x $300,000

Commission on first $300,000 = $18,000

So, the remaining commission earned by the agent on the amount that exceeds $300,000 is:

Total commission - Commission on first $300,000 = $21,150 - $18,000

Total commission - Commission on first $300,000 = $3,150

Now, we know that the commission earned on the remaining amount is 3% of the sales price that exceeds $300,000. Let's assume the sales price of the property is x. Then we can write the following equation:

3% of (x - $300,000) = $3,150

We can simplify this equation as follows:

0.03(x - $300,000) = $3,150

x - $300,000 = $3,150 / 0.03

x - $300,000 = $105,000

x = $300,000 + $105,000

x = $405,000
