When the expression y² + 10 y + 33 is written as a combination of a square of a binomial expression and an integer, the value of the integer is 8
We are given an expression y² + 10 y + 33 and this expression can be written as a combination of a square of a binomial and an integer. we need to find the value of the integer.
= y² + 10 y + 33
Write 10 y = 2 (5) (y)
= y² + 2 (5) (y) + 33
Write 33 = 25 + 8
= y² + 2 (5) (y) + 25 + 8
Write 25 = 5²
= y² + 2 (5) (y) + 5² + 8
Write y² + 2 (5) (y) + 5² = (y + 5)²
= (y + 5)² + 8
So, here (y + 5)² is the square of the Binomial expression and 8 is the integer.

C.) Using Descartes' Rule of Signs, how many possible positive, negative, and complex (imaginary) zeros are possible... list all possibilities. It would be helpful to make a table (4 points)
D.) Describe the end behavior of this graph. (2 points)
The total zeros the function has is 4
See below for other solutions
How many total zeros does this function have?This is the degree of the function
The degree of f(x) = -x^4 + x^3 - 7x2 + 9x + 18 is 4
So, the number of zeros is 4
The possible rational zerosStart by writing out the factors of the leading coefficient and the constant term
p = ±(1, 2, 3, 6)
q = ±1
So, we have
p/q = ±(1, 2, 3, 6)/±1
p/q = ±(1, 2, 3, 6)
How many types of zeros are possibleHere, we find the number of changes in sign in the coefficients of the polynomial function.
f(x) = -x^4 + x^3 - 7x2 + 9x + 18
Number of sign changes = 3
Calculate f(-x) for the negative zeros
f(-x) = -(-x)^4 + (-x)^3 - 7(-x)^2 + 9(-x) + 18
f(-x) = -x^4 - x^3 - 7x^2 - 9x + 18
Number of sign changes = 1
This means that there is the possibility of 3 positive zeros, 1 negative zero, and 1 complex zero.
The end behavior of the graph of the functionHere, we make use of the leading term, -x4, which is negative.
This implies that the graph will approace -∝ as x approaches +∝ and will approach +∝ as x approaches -∝.

you watch a roulette wheel spin 7 consecutive times and the ball lands on a red slot each time. what is the probability that the ball will land on a red slot on the next spin?
The probability that the ball will fall into a red slot during the following spin is 0.14.
To calculate the probability of an occurrence, divide the total number of outcomes by the total number of possible outcomes. The concepts of probability and odds are distinct. Odds are determined by dividing the probability of a situation happening by the probability that it won't happen. Probability is a metric used to determine how likely an event is to occur.

Answer:
f(x) = 0.8x - 5
Step-by-step explanation:
the equation of a linear function is of the form
f(x) = ax + b
to find a and b use the given points
f(5) = - 1 ⇒ (5, - 1)
f(0) = - 5 ⇒ (0, - 5 )
substituting into the standard form , (0, - 5 )
- 5 = a(0) + b
- 5 = b
then
f(x) = ax - 5
substitute the other point (5, - 1 )
- 1 = 5a - 5 ( add 5 to both sides )
4 = 5a ( divide both sides by 5 )
[tex]\frac{4}{5}[/tex] = a

The degree and leading coefficient of each polynomial in one variable is given below :- (2). degree 3; leading coefficient 8 | (4). degree 6; leading coefficient | (6). not a polynomial
The "leading coefficient" is the coefficient of the highest-degree term in the sum of terms that makes up a polynomial.
These expressions all have one variable, so the number of variables is not an issue in any case. All of the exponents are positive integers, so that is not an issue in any case. However, the variable appears in the denominator in the expression of problem 6, so that sum is not a polynomial.
______
(2). In order to put this into the form we recognize as a polynomial, the expression must be "simplified' by performing the multiplication of the two factors:
= 8x³ -4x² +6x -3
The leading coefficient is the coefficient of the highest-degree term, which is the product of the highest-degree terms of the factors. That product is ...
(2x)(4x²) = 8x³
so the leading coefficient is 8. The variable is to the 3rd power, so the degree is 3.

does anything in the plot of the semimajor axis versus the period change when the eccentricity is changed?
Yes, the connection between the semimajor axis and an orbit's period varies as the eccentricity of the orbit changes.
What is eccentricity?In geometry, the eccentric definition is the distance from any point on a conic section to the focus divided by the perpendicular distance from that point to the nearest directrix. In general, eccentricity aids in determining the curvature of a form. The eccentricity grows as the curvature lowers.
Here,
In general, an orbit's period is proportional to the square root of the semimajor axis multiplied by three. This connection, however, is only valid for circular orbits with zero eccentricity. When the eccentricity is larger than zero, the period of the orbit is still determined by the magnitude of the semimajor axis, but it is also determined by the form of the orbit as given by the eccentricity. The relationship between the semimajor axis and the period in this situation is not as straightforward as a proportionate relationship.
As a result, modifying an orbit's eccentricity modifies the connection between the semimajor axis and the period.

20. A hollow spherical vessel has internal and external radii of 6 cm and 6.4 cm respectively. Calculate the mass of the vessel if it is made of metal of density 10 g/cm³. nuorted cone of diameter and height
The mass of the vessel if it is made of metal of density 10 g/cm³ is 1993 g.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We know that;
Volume of sphere = 4/3 πr³
Hence, For internal;
⇒ Volume of sphere = 4/3 πr³
⇒ Volume of sphere = 4/3 × 3.14 × (6)³
⇒ Volume of sphere = 904.32 cm³
For external;
⇒ Volume of sphere = 4/3 πr³
⇒ Volume of sphere = 4/3 × 3.14 × (6.4)³
⇒ Volume of sphere = 1097.5 cm³
Thus, Volume of sphere between sphere is,
⇒ 1097.5 - 904.32
⇒ 193.2 cm³
Here, it is made of metal of density 10 g/cm³.
Hence, the mass of the vessel is,
⇒ 193.2 × 10
⇒ 1932 g

Consider having numbers from 1–20. Write the ratio representing the following (express in the simplest term, if possible):
1. Odd numbers to all numbers involved
2. Numbers divisible by 5 to even numbers
3. Numbers greater than 7 to numbers less than 12
4. Even numbers greater than 5 but less than 17 to all numbers involved
the ratio representing the above-described number are given as follows;
In mathematics, parity refers to whether an integer is even or odd. If an integer is a multiple of two, it is even; otherwise, it is odd. For instance, 4, 0, 82 are even because 3, 5, 7, and 21 are all odd numbers.
With regard to the above ratios:
1) Odd numbers to all numbers involved:
There are 10 odd numbers from 1 to 20 (1, 3, 5, 7, 9, 11, 13, 15, 17, 19). So, the ratio of odd numbers to all numbers involved is 10/20 = 1/2.
2) Numbers divisible by 5 to even numbers:
There are 4 numbers from 1 to 20 that are divisible by 5 (5, 10, 15, 20). Out of these 4 numbers, 2 are even (10, 20). So, the ratio of numbers divisible by 5 to even numbers is 4/2 = 2/5.
3) Numbers greater than 7 to numbers less than 12:
There are 4 numbers less than 12 (1 to 7) and 5 numbers greater than 7 (8 to 20). So, the ratio of numbers greater than 7 to numbers less than 12 is 5/4.
4) Even numbers greater than 5 but less than 17 to all numbers involved:
There are 6 even numbers greater than 5 but less than 17 (6, 8, 10, 12, 14, 16). So, the ratio of these even numbers to all numbers involved is 6/20 = 3/10 = 1/2 * 3/5 = 3/10.

assuming that nothing is known about the shape of the distribution for the data, what percentage of dentists use less than 102 units of local anesthetics per week?\
If the data has a mound-shaped distribution, then percentage of dentists who use less than 102 units of local anesthetics per week is 84% .
The Distribution is mound shaped and symmetric
we have to find percentage of dentists use less than 102 units of local anesthetics per week ;
Since the distribution is mount shaped , 68% of the data values are within 1 standard deviations of the mean (by the empirical rule) and 32% of data values are more than 1 standard deviations (23) from mean (79) .
Since , Distributions is symmetric, we expect about 16% of the data values to be more than 1 standard deviations below the mean, and about 16% of data values to be more than 1 standard deviations above mean.
So , 68% + 16% = 84% of the data values is expected to be less than 102.
Therefore , 84% of dentists use less than 102 units of local anesthetics per week .
The given question is incomplete , the complete question is
A study published in Current Allergy & Clinical Immunology (Mar. 2004) investigated allergic reactions of dental patients to local anesthetics. Based on a survey of dental practitioners, the study reported that the mean number of units (ampoules) of local anesthetics used per week by dentists was 79, with a standard deviation of 23. Suppose we want to determine the percentage of dentists who use less than 102 units of local anesthetics per week.
Assuming that the data has a mound-shaped distribution, what percentage of dentists use less than 102 units of local anesthetics per week ?
