Final answer:
A cubic function example is f(x) = x^3, which shows a curve with odd function symmetry that decreases with negative x values and increases with positive ones.
Explanation:
An example of a cubic function would be the function f(x) = x3. This function represents a basic cubic equation where the variable x is raised to the third power, or cubed. The graph of this function is a curve that demonstrates symmetry about the origin, with the curve decreasing for negative values of x and increasing for positive values. As x is cubed, it indicates that the function has an odd function symmetry.

What is the simplified form of cos C ?
A. √2/2
B. 1
C. √2
D. √5/2
The simplified form of cos C is sqrt(2)/2.
What is cos ?"Cos is the cosine function of a right triangle in trigonometry. Cos function is the ratio of adjacent side and hypotenuse. It helps us to find the length of the sides of the triangle, irrespective of given angle.
Suppose we have a right triangle and α is the angle between adjacent side and hypotenuse, then as per the cos function, we can write
Cos α = Adjacent Side/Hypotenuse"
Here, given the base of the triangle is = 5
and hypotenuse is = 5sqrt2
So, [tex]cos C = 5/5\sqrt2 = 1/\sqrt2[/tex]
Multiplying both numerator and denominator by sqrt2
We get [tex]\sqrt2/2[/tex].
Hence, the value of cos C is [tex]\sqrt2/2[/tex]

Isabella's ballet class is preforming a spring recital for which they need butterfly costumes. Each butterfly costume is made from 3 3/5 yards of fabric. Use Distributive Property to find the number of yards of fabric needed for 5 costumes. (Hint: A mixed number can be written as the sum of an integer and a fraction.)
We are given that:
fabric required = 3 3/5 yards
costumes = 5
We can write fabric required as a fraction in the form of:
(3 * 5) + 3 = 18
fabric required = 18 / 5 yards
So total fabric required is = (18 / 5 yards) * 5 = 18 yards
Answer:
18 yards

if f(x) = 2x-5, which expression represents f(x+1)
Answer: The required expression for f(x+1) is 2x-3.
Step-by-step explanation: We are given the following function :
[tex]f(x)=2x-5~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
We are to find the expression for f(x+1).
To find the expression for f(x+1), we need to substitute x+1 in place of x in (i).
So, we get from expression (i) that
[tex]f(x+1)\\\\=2(x+1)-5\\\\=2x+2-5\\\\=2x-3.[/tex]
Thus, the required expression for f(x+1) is 2x-3.
if a number is a natural number, then it is also a whole number? what is the Inverse, the Converse, the Contrapositive, and the Bi-Conditional? and what is the Truth value for each one?
The original statement, 'If a number is a natural number, then it is also a whole number' is true because every natural number falls into the set of whole numbers. However, its converse is not true, as whole numbers include 0, which is not a natural number, making the inverse and the bi-conditional false. The contrapositive of the statement is true, maintaining logical consistency.
Explanation:If a number is a natural number, then it is indeed also a whole number. The relationship between natural numbers and whole numbers is an inclusive one, where all natural numbers (1, 2, 3, ...) are also whole numbers (0, 1, 2, 3, ...). The original statement can be expressed in logical form as: If P, then Q, where P is 'a number is a natural number,' and Q is 'it is also a whole number.'
Here is how the other forms of the statement look:
The inverse negates both the hypothesis and the conclusion: If not P, then not Q. So, 'If a number is not a natural number, then it is not a whole number.'
The converse switches the hypothesis and the conclusion: If Q, then P. For our statement, 'If a number is a whole number, then it is also a natural number.'
The contrapositive negates and switches the hypothesis and conclusion: If not Q, then not P. Therefore, 'If a number is not a whole number, then it is not a natural number.'
The bi-conditional states that P if and only if Q: A number is a natural number if and only if it is a whole number.'
The truth value of the original statement is true since all natural numbers are whole numbers. However, the converse is not true because whole numbers also include 0, which is not a natural number. Consequently, the inverse and the bi-conditional are false. The contrapositive is true because if it is not a whole number, then it can't be a natural number (considering that whole numbers include all natural numbers).

Billy could drive 256.5 miles in 4.5 hours.
Explanation:To find the number of miles Billy could drive in 4.5 hours, we will use the concept of direct variation. Direct variation states that when two variables are directly proportional, their ratio is constant.
Given that Billy drives 171 miles in 3 hours, we can set up a proportion:
Miles driven / Hours in the car = Miles driven / Hours in the car
Using the given values, we have:
171 / 3 = x / 4.5
To solve for x, cross multiply:
3x = 171 * 4.5
Divide both sides by 3:
x = (171 * 4.5) / 3
Simplifying the right side of the equation gives us:
x = 256.5
Therefore, Billy could drive 256.5 miles in 4.5 hours.

Which graph represents the solution set of the system of inequalities?
{−2x+y≤4
y>x+2
The correct graph is:
First graph
Step-by-step explanation:The first inequality is:
[tex]-2x+y\leq 4[/tex]
The graph of this inequality is a straight solid line ( since the inequality is a inequality with a equality sign i.e. not strict ) which passes through (-2,0) and (0,4) and the shaded region is towards the origin as it passes the zero point test.
The second inequality is:
[tex]y>x+2[/tex]
is a dotted straight line (since the inequality is strict) which passes through (-2,0) and (0,2) and the shaded region is away from the origin as it fails the zero point test.
Hence, the correct graph is the first graph.

The sum of the probabilities of any event and its complement is always 1.
The student's question involves probability and arrangement of objects, which falls under the subject of mathematics. More specifically, the problem relates to permutations and the fundamental counting principle, combined with basic probability concepts.
Statement 36: The sample space is the set of all possible outcomes that can occur. Since there are 12 different books, the sample space consists of these 12 unique titles, where 8 are fiction (F1 to F8) and 4 are nonfiction (N1 to N4). The sample space is therefore: {F1, F2, F3, F4, F5, F6, F7, F8, N1, N2, N3, N4}.
Statement 37: The sum of the probabilities of an event and its complement is always 1. This is because an event and its complement together cover all possible outcomes in the sample space.

Talia is packing a moving box. She has a square-framed poster with an area of 9 square feet. The cube-shaped box has a volume of 30 cubic feet. Will the posture lie flat in the box?
Answer: Yes, the posture will be lie flat in the box.
Step-by-step explanation:
since we have given that
Area of square framed poster = 9 sq. feet
Volume of cube shaped box = 30 cubic feet.
As we know the formula for "volume of cube":
[tex]Volume=30\\\\a^3=30\\\\a=\sqrt[3]{30}=3.10\ feet[/tex]
So, Area of cube shaped box would be
[tex]6a^2=6\times (3.1)^2=57.9\ ft^2[/tex]
Since the cube box is large enough so that the posture will lie flat in the box.

If the area of one face of a cube is 25 cm2 . what the surface area of the cube will be is: 150cm²
Let x represent the surface area of the cube
Hence:
Surface area of a cube of edge x =6x²
Surface area of the cube =6(25cm)²
Surface area of the cube=150cm²

The probability that concert tickets are available by telephone is 0.91. for the same event, the probability that tickets are available through a web site is 0.96. assume that these two ways to buy tickets are independent. what is the probability that someone who tries to buy tickets both through the internet and by the telephone will obtain at least one ticket? round your answer to four decimal places (e.g. 98.7654).
Final answer:
The probability of obtaining at least one concert ticket through both the internet and by telephone is 0.9984.
Explanation:
The probability that someone who tries to buy tickets both through the internet and by telephone will obtain at least one ticket is 0.9984.
To calculate this, we first find the probability of not getting any tickets through either method: P(no tickets) = P(no tickets by phone) * P(no tickets online). Then, subtract this probability from 1 to get the probability of obtaining at least one ticket: P(at least one ticket) = 1 - P(no tickets).
