Which letter labels a vertex?
A. A only
B. B
C. C
D. A and D
Answer:
l think it is c
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
In geometry, a vertex, often denoted by letters such as P, Q, R, S, is a point where two or more curves, lines, or edges meet. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedra are vertices.

how does (4x + 5)(3x + 10) demonstrate the closure property for polynomials?
Answer:
Step-by-step explanation:
A polynomial is a finite sum of terms in which all variables have whole number exponents and no variable appears in a denominator.
box4aa
box1
rembox22
The leading term in a polynomial is the term of highest degree.
The constant term in a polynomial is the term without a variable.
Polynomials: YES or NO
3x½
NO - exponent is not a whole number
polyd
NO - the variable is in the denominator
-3x2
YES - satisfies the polynomial definition
polyd1
NO - the square root of x can be written with a fractional exponent of x.
2x-3
NO - exponent is not a whole number.
Negative exponent places x3 in denominator.
polyrad3
YES - the exponent of x is 1 which is OK.
The coefficient being radical 3 is not a problem.
Classification by Terms
monomial
one term: 12, 4x, x2, -5xy
binomial
two terms: 2x - 1, x2 - 4
trinomial
three terms: x2 + 2x + 1
polynomial - one or more terms: polynomial means "many", but it can also be one term.
The ending of these words "nomial"
is Greek for "part".
Classification by Degree
Linear - degree of 1 or 0: 3x + 1 or 12
Quadratic - degree of 2: 2x2 - x + 7
Cubic - degree of 3: 3x3 + 4x2 + 3x + 5
definition The degree of a term with whole number exponents is the sum of the exponents of the variables, if there are variables. Non-zero constants have degree 0, and the term zero has no degree. Example: 6x2 has a degree of 2; 4x2y3 has a degree of 5 (the sum of 2 and 3).
definition
The degree of a polynomial is the highest degree of its terms.
Example: 3x2 + 4x + 1 has a degree of 2; x3 - x2 + 5x - 2 has a degree of 3
The standard form of a polynomial is when all like terms are combined and the degrees are arranged in descending order.
Polynomial: 2x + 3x5 + 4x3 - 8
Standard form: 3x5 + 4x3 + 2x - 8
3x5 + 4x3 + 2x1 - 8x0
boxdegree1
Will we ever really use the degree?
Knowing the "degree" of a polynomial function will let you determine the most number of solutions the function may have, and the most number of times the function will cross the x-axis.
FYI: The standard form of a polynomial is formally written as anxn + an - 1xn - 1 + ... + a2x2 + a1x + a0, where n is a non-negative integer, and a0, a1, a2, ..., an are real number constant coefficients with an ≠ 0.
bullet Polynomials and Closure:
Polynomials form a system similar to the system of integers, in that polynomials are closed under the operations of addition, subtraction, and multiplication.
CLOSURE: Polynomials will be closed under an operation if the operation produces another polynomial.
• Closure under Addition: (2x2 + 3x + 4) + (x2 - 5x - 3) = 3x2 - 2x + 1
When adding polynomials, the variables and their exponents do not change. Only their coefficients will possibly change. This guarantees that the sum has variables and exponents which are already classified as belonging to polynomials. Polynomials are closed under addition.
• Closure under Subtraction: (2x2 + 3x + 4) - (x2 - 5x - 3) = x2 + 8x + 7
When subtracting polynomials, the variables and their exponents do not change. Only their coefficients will possibly change. This guarantees that the difference has variables and exponents which are already classified as belonging to polynomials. Polynomials are closed under subtraction.
• Closure under Multiplication: (x + 1)(x2 + 4x + 3) = x3 + 5x2 + 7x + 3
When multiplying polynomials, the variables' exponents are added, according to the rules of exponents. Remember that the exponents in polynomials are whole numbers. The whole numbers are closed under addition, which guarantees that the new exponents will be whole numbers. Consequently, polynomials are closed under multiplication.
What about division?
Polynomials are NOT closed under division. Look at this simple counterexample:
closure1
When dividing variables with exponents, there is the possibility of creating a negative exponent. Negative exponents are not allowed in polynomials.

a wildlife manager determines that the function y=200x1.07* represents the deer population at a state park x years after the population is first counted. what is the population after 12 years? what is the initial population? what is the percentage rate? complete the table below.
Answer:
Table:
0,200
4, 262
8,344
12, 450
Population after 12 years is 450 deer
Initial population is 200 deer.
Step-by-step explanation:
You take the x in the table and plug it in as an exponent so you will need a calculator or multiple the 1.07 by that many times so 1.07 12 times multipled by itself. and the initial is 0 years so anything to the exponent of 0 is 1 so that show i got 200 for the x=0

Someone can steal the food lol
The probability of a person randomly selecting a cheesecake, putting it back, and then selecting a cookie is 1/100, 0.01, or 1%.
We have,
To find the probability of selecting a cheesecake, putting it back, and then selecting a cookie, we need to determine the individual probabilities of each event and multiply them together.
The probability of selecting a cheesecake is 1 out of 10, since there is one cheesecake out of 10 options.
Therefore, the probability of selecting a cheesecake is 1/10.
After putting the cheesecake back, the total number of options remains the same, so the probability of selecting a cookie is also 1 out of 10, which is 1/10.
To find the probability of both events happening, we multiply the individual probabilities:
Probability of selecting a cheesecake and then a cookie
= (1/10) * (1/10)
= 1/100
Expressed as a decimal, the probability is 0.01.
To express it as a percentage, we multiply the decimal by 100:
Probability = 0.01 * 100 = 1%
Therefore,
The probability of a person randomly selecting a cheesecake, putting it back, and then selecting a cookie is 1/100, 0.01, or 1%.

a whole number by a unit fraction is the same as multiplying a whole number by the of the unit fraction.
Answer:
A whole number divided by a unit fraction is the same as multiplying a whole number by the inverse of the unit fraction.
Step-by-step explanation:
Given
[tex]8 \div \frac{1}{5} = 40[/tex]
[tex]8 * 5 = 40[/tex]
Required
Explain why both expressions are correct
No dropdown to select from. So, I will provide a general solution.
When a number is divided by a fraction.
Take for instance:
[tex]8 \div \frac{1}{5}[/tex]
The above can be expressed as the product of the number and the inverse of the fraction.
The inverse of 1/5 is 5.
So, we have:
[tex]8 \div \frac{1}{5} = 8 * 5[/tex]
The result of the above expression is:
[tex]8 \div \frac{1}{5} = 8 * 5 = 40[/tex]
