Answer:
2x^2 + x + 9 + (18/(x+2))
Step-by-step explanation:
To find the result when 2x^3 - 5x^2 - 9x + 18 is divided by x + 2 using the long division method, you can follow these steps:
Divide the first term of the dividend (2x^3) by the first term of the divisor (x). The result is 2x^2.
Multiply the divisor (x + 2) by 2x^2. The result is 2x^3 + 4x^2.
Subtract this result from the dividend (2x^3 - 5x^2 - 9x + 18). The result is -x^2 - 9x + 18
Bring down the next term of the dividend (-5x^2) and add it to the result from step 3. The result is -6x^2 - 9x + 18
Divide -6x^2 by -6x and the result is x.
Multiply the divisor by x. The result is x^2 + 2x
Subtract this result from the result of step 4. The result is -9x + 18
Bring down the next term of the dividend (-9x) and add it to the result from step 7. The result is -18x + 18
Divide -18x by -18 and the result is x
Multiply the divisor by x. The result is x^2 + 2x
Subtract this result from the result of step 8. The result is 18
Therefore, the quotient is 2x^2 + x + 9 and the remainder is 18
So the result when 2x^3 - 5x^2 - 9x + 18 is divided by x + 2 is 2x^2 + x + 9 + (18/(x+2))

The number of hot cocoas that Mei Mei would be predicted to sell if the day’s high temperature was of 42 ºF is given as follows:
58.
How to define the linear function?The slope-intercept definition of a linear function is given as follows:
y = mx + b.
For which the parameters are given as follows:
m is the slope, representing the rate of change.b is the intercept, representing the value of y when x = 0.The function touches the y-axis at y = 100, meaning that the intercept b is defined as follows:
b = 100.
When x increases to six, y decays to 94, hence the slope m is obtained as follows:
m = (94 - 100)/(6 - 0)
m = -1.
Hence the function that predicts the amount of hot cocoa sold for a high temperature of x ºF is given as follows:
y = -x + 100.
The estimate if the high temperature was of 42 ºF is given as follows:
y = -42 + 100
y = 58.

The height is 2 and radius is √2 of the largest right circular cylinder that can be put into a sphere of radius √3.
What is circular cylinder?A cylinder whose bases are circular in shape and parallel to each other is called the right circular cylinder. It is a three-dimensional shape.
Given that the radius of a sphere R = √3
Let the radius of the cylinder is r and the height of the cylinder is h.
than.
r² = R² − h²/4
and Vc = πr²h
⇒ Vc = π(R² − h²/4)h
⇒ Vc = πR²h − πh³/4
dVc/dh = πR² − 3πh²/4
(dVc/dh)R=√3 = 3π − 3πh²/4
For maximum or minimum volume,
dVc/dh = 0
⇒ 3π − 3πh²/4 = 0
⇒ 3πh²/4 = 3π
⇒ 3πh² = 3π*4
⇒ h² = 4
⇒ h=2
Also, dVc/dh changes sign from positive to negative in the neighborhood of h=2. Hence, h=2 is a maximum point.
r² = R² − h²/4
⇒ r² = (√3)² - 2²/4
⇒ r² = 3 - 1
⇒ r² = 2
⇒ r = √2
So, the height is 2 and radius is √2 of the largest right circular cylinder

initially to get the difference between the x-coordinates of points $r$ and $s$, and multiply the values by 2/3. let us consider that value as $dx$.
and to get the difference between the y-coordinates of points $r$ and $s$, and multiply it by 2/3. let us assume the value as $dy$. then add $dx$ to the x-coordinate of point $r$ and $dy$ to the y-coordinate of point $r$.on doing certain operations we get as:
hence the coordinates of the point at two-thirds of the way from $r$ to $s$ is $(x,y)$ can be established as
x = -6 + (15 - (-6))(2/3) = -6 + 21(2/3) = -6 + 14 = 8
y = 19 + (-5 - 19)(2/3) = 19 - 24(2/3) = 19 - 16 = 3

an opinion poll asked a random sample of high school couples in the united states whether they believe they will marry their high school sweetheart. a researcher believes more than 25% of high school couples believe they will marry. which null and alternative hypotheses should be used to test this claim?
The null hypothesis would be H0: p <= 0.25 and the alternative hypothesis would be Ha: p > 0.25
The null hypothesis represents the default assumption that there is no significant difference between the proportion of high school couples who believe they will marry their high school sweetheart and the researcher's claim that more than 25% of high school couples believe they will marry.
The alternative hypothesis represents the claim that the researcher wants to test, which is that the proportion of high school couples who believe they will marry their high school sweetheart is greater than 25%.
So, the null hypothesis would be:
H0: p <= 0.25 (where p is the proportion of high school couples who believe they will marry their high school sweetheart)
The alternative hypothesis would be:
Ha: p > 0.25 (where p is the proportion of high school couples who believe they will marry their high school sweetheart)

The following curve passes through (3,1). Use the local linearization of the curve to find the approximate value of y at x
m = the slope of the curve at x=3 and b = the y-intercept at x=3. Therefore, the approximate value of y at x=2
We can use the local linearization of the curve to approximate the value of y at x=2.
The local linearization of the curve is given by the equation y = mx + b, where m is the slope of the curve at x=3 and b is the y-intercept at x=3.
Let m be the slope of the curve at x=3 and b be the y-intercept at x=3.
The slope of the curve at x=3 can be found by calculating the derivative of the curve at x=3.
The y-intercept at x=3 can be calculated by substituting x=3 into the equation of the curve and solving for y.
Therefore, m = the slope of the curve at x=3 and b = the y-intercept at x=3.
Substituting the values of m and b into the equation of the local linearization, we get the equation y = mx + b.
Substituting x=2 into the equation, we get y ≈ 0.5 + 1 = 1.5.
Therefore, the approximate value of y at x=2

A worker just switched on a newer line that can fill 12 barrels per minute. In a little while, the two lines will have filled an equal number of barrels. How many barrels will each line have filled? How long will that take?
It takes 10 minutes for the two lines to have filled an equal number of barrels
How many barrels will each line have filled?Each line will have filled 90 barrels
Let “x” be the number of minutes
The old conveyer line has filled 20 barrels of paint, and is filling more at a rate of 7 barrels per minute
Thus, a equation is framed as follows:
Old conveyor: 20 + 7(number of minutes)
Old conveyor: 20 + 7x ------- eqn 1
A worker just switched on a newer line that can fill 9 barrels per minute
Thus, a equation is framed as follows:
New conveyor: 9(number of minutes)
New conveyor: 9x -------- eqn 2
In a little while, the two lines will have filled an equal number of barrels.
Thus, eqn 1 must be equal to eqn 2
Thus it takes 10 minutes for the two lines to have filled an equal number of barrels

7.65%.
The total amount in an account to the nearest cent after 3 years if the interest is compounded annually on an investment of $5600 at 7.65% is $6,986.02
To find the total amount in the account after 3 years, we need to use the formula for compound interest:
A = P(1 + r/n)^(nt)
where A is the total amount, P is the initial investment (principal), r is the annual interest rate (expressed as a decimal), n is the number of times the interest is compounded per year, and t is the number of years.
In this case, P = $5600, r = 0.0765, n = 1 (because the interest is compounded annually), and t = 3. Plugging these values into the formula gives:
A = 5600(1 + 0.0765)^3
A = $6,986.02
So, the total amount in the account after 3 years, to the nearest cent, would be $6,986.02

what is the least positive integer value of $x$ such that $(2x)^2 2\cdot 37\cdot 2x 37^2$ is a multiple of 47?
The least positive integer value of x is 1
We can start by expressing the expression (2x)^2 2372x 37^2 as a multiple of 47.
47 | (2x)^2 2372x 37^2
Since 47 is a prime number, we can use the property that a multiple of a prime number is a number that can be divided by that prime number without leaving a remainder.
So, we need to find the least positive integer value of x such that (2x)^2 2372x 37^2 is divisible by 47.
We can start by assuming (2x)^2 2372x 37^2 as (2x)^2 2372x 37^2 = 47*k, where k is any integer.
We can start testing values of x starting from 1,
x=1 : (21)^2 * 23721 * 37^2 = 4 * 74 * 1369 = 47 * 2028,
x=2 : (22)^2 * 23722 * 37^2 = 16 * 148 * 1369 = 47 * 6912,
and so on.
So the least positive integer value of x such that (2x)^2 2372x 37^2 is a multiple of 47 is x=1.

The length of one diagonal of a rhombus is 6 times the length of the other diagonal. Write an expression that represents the perimeter of the rhombus, where d represents the shorter diagonal.
Answer:
A rhombus is a four-sided shape with all sides equal in length, and opposite angles equal. The diagonals of a rhombus bisect each other at right angles and they are equal in length.
In this case, the length of one diagonal of the rhombus is 6 times the length of the other diagonal. Let's call the length of the shorter diagonal "d", and the length of the longer diagonal "6d".
To find the perimeter of the rhombus, we can add up the lengths of all four sides. Since all sides of a rhombus are equal, we can find the perimeter by multiplying the length of one side by 4.
To find the length of one side, we can use the Pythagorean theorem to find the length of the side in terms of d, the shorter diagonal.
We know that d^2 + (3d)^2 = s^2, where s is the length of one side.
After simplifying, we get: d^2 + 9d^2 = s^2
s = √10d^2
so the perimeter is 4s = 4 √10d^2
Therefore, the perimeter of the rhombus can be represented by the expression 4* √10d^2 where d represents the length of the shorter diagonal.
Answer:
14d
Step-by-step explanation:
First the short diagonal is d, so we can mark it as d:
d
Second we have 6 times that, so 6d:
d+6d
Then we multiply it by two since a rhombus has 4 sides:
2d+12d
Then we simplify:
14d

The equation showing the total cost for purchasing x tickets is given as y = 12.5x + 7
What is an equation?An equation is a expression that shows the relationship between numbers and variables.
The standard form of a linear equation is:
y = mx + b
Where m is the rate of change and b is the y intercept
Let y represent the total cost for x tickets.
From the table, using the points (2, 32) and (6, 82):
y - 32 = [(82 - 32)/(6 - 2)](x - 2)
y - 32 = 12.5(x - 2)
y = 12.5x + 7
The equation is given as y = 12.5x + 7

What is the symbol of absolute value?
The symbol of absolute value is two vertical bars (||).
The absolute value of a number is the distance between that number and zero on a number line. The absolute value of a number is always positive, regardless of the sign of the original number. For example, the absolute value of -5 is 5 and the absolute value of 5 is also 5.
In mathematical notation, the absolute value of a number is represented by placing the number between the vertical bars, like this: |x|. When the absolute value is applied to a variable or an expression, the result is the positive value of that variable or expression. For example, |-5| = 5, and |5| = 5.
The absolute value is used in many branches of mathematics, including algebra, calculus and geometry, and it is used to represent the magnitude of a number, regardless of its sign, and also it is used to define the distance between two points on a number line.

Each deli sandwich made uses 3/8 pound of roast beef. marisa started with 5 pounds of roast beef and now has 2 3/4 pounds left. how many deli sandwiches did she make?
Answer:
To solve this problem, we will use the following steps:
Step 1: Convert the amount of roast beef used in each sandwich to a decimal by dividing the numerator by the denominator: 3/8 pound = 0.375 pound
Step 2: Subtract the amount of roast beef that Marisa has left from the amount of roast beef that she started with to find the amount of roast beef used: 5 - 2.75 = 2.25 pounds
Step 3: Divide the amount of roast beef used by the amount of roast beef used in each sandwich: 2.25 pounds / 0.375 pounds = 6
Final Answer: Marisa made 6 deli sandwiches.
a youth indoor soccer team has 6 starting players. the starting players must consist of 3 boys and 3 girls. there are 7 boys and 6 girls on the team. each player can play each position. in how many ways can the coach select players to start the game?
The coach can select the 6 starting players in 20 different ways, as probability are 6 players to choose from and they must consist of 3 boys and 3 girls. There are 7 boys and 6 girls, so each player is eligible to play each position. To calculate this, the formula 6! / (3! * 3!) is used.
1. Calculate 6 factorial (6!) which is 6*5*4*3*2*1 = 720
2. Calculate 3 factorial (3!) which is 3*2*1 = 6
3. Calculate 3 factorial (3!) again which is also 6
4. Divide 6! by (3! * 3!) which is 720 / (6 * 6) = 20
When selecting a starting lineup for an indoor soccer team consisting of 6 players who must be 3 boys and 3 girls, there are 20 possible combinations. To calculate this, the coach must use the formula 6! / (3! * 3!). This formula is used to calculate the number of possible combinations when selecting a certain number of items from a set of items, where all items are unique. 6! is 6 factorial, which is calculated by multiplying the numbers from 6 down to 1 (6*5*4*3*2*1). 3! is 3 factorial, which is calculated by multiplying the numbers from 3 down to 1 (3*2*1). When 6! is divided by the product of 3! multiplied by 3!, the result is 20. This shows that the coach can select the 6 starting players in 20 different ways, as there are 6 players to choose from and they must consist of 3 boys and 3 girls. There are 7 boys and 6 girls, so each player is eligible to play each position.
