The change in demand is $15 per barrel.
What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that the price of oil increases from 20 to 5 per barrel.
A change in quantity demanded refers to a change in the specific quantity of a product that buyers are willing and able to buy. This change in quantity demanded is caused by a change in the price.So we can write the change in demand as -
$20 per barrel - $5 per barrel
$15 per barrel
Therefore, the change in demand is $15 per barrel.

Dylan is going to invest $95,000 and leave it in an account for 18 years. Assuming the interest is compounded monthly, what interest rate, to the nearest hundredth of a percent, would be required in order for dylan to end up with $251,000?.
The interest rate required to end up with $251,000 is 6.9% to the nearest hundredth of a percent.
Compound interest is computed on the principal as well as the interest accumulated over the preceding period. It differs from simple interest in that interest is not added to the principal when computing interest for the next month.
The formula to calculate the compound interest is:
A = P * (1 + r/n)^(nt),
where:
A = final amount
P = principal amount ($95,000)
r = interest rate
n = number of compounding periods per year
t = time in years (18)
Rearranging the formula to solve for r:
r = (A/P)^(1/nt) - 1
Plugging in the given values:
r = ($251,000/$95,000)^(1/18*12) - 1
= 0.069 or 6.9%

prove that the function h(x)=(1-x^2) ^1/3 is its own inverse by showing that h(h(x)) =x.
It is proved that the function h(x)=(1-x^2) ^1/3 is its own inverse by showing that h(h(x)) =x.
The inverse of a function f is denoted by f-1 and it exists only when f is both one-one and onto function. Note that f-1 is NOT the reciprocal of f. The composition of the function f and the reciprocal function f-1 gives the domain value of x.
(f o f-1) (x) = (f-1 o f) (x) = x
For a function 'f' to be considered an inverse function, each element in the range y ∈ Y has been mapped from some element x ∈ X in the domain set, and such a relation is called a one-one relation or an injunction relation. Also the inverse f-1 of the given function has a domain y ∈ Y is related to a distinct element x ∈ X in the codomain set, and this kind of relationship with reference to the given function 'f' is an onto function or a surjection function. Thus the inverse function being an injunctive and a surjection function, is called a bijective function.
The given function is h(x) = (1-x²)^1/3
We have to find h(h(x)).
Put h(x) in place of x in above function:
h(h(x)) = (1-((1-x²)^1/3)²)^1/3
After solving the above equation, we get
h(h(x)) = x
Thus, it is proved that the function h(x)=(1-x^2) ^1/3 is its own inverse by showing that h(h(x)) =x.

parametrize the line segment passing through (1, 2, 1) and (2, 4, 3).
The parametrize line will be r(t)=(1,2,1)+t(1,2,2).
How to parametrize a line?
In order to parametrize a line, you need to know at least one point on the line, and the direction of the line. If you know two points on the line, you can find its direction. The parametrization of a line is r(t) = u + tv, where u is a point on the line and v is a vector parallel to the line. There are lots of possible such vectors u and v. To find one such vector v, find the difference between any two points on the line.
Example: If we want to parametrize the straight line passing through (1,1,1) and (4,6,2), we can take u = (1,1,1) and v = (4,6,2) - (1,1,1) = (3,5,1). So one possible parametrization for this line is r(t) = (1,1,1) + t(3,5,1). We can also write this as:
x(t) = 1 + 3t
y(t) = 1 + 5t
z(t) = 1 + t
Now,
For points (1, 2, 1) and (2, 4, 3)
u=(1,2,1)
v=(2,4,3)-(1, 2, 1)
v=(1,2,2)
so the parametrized line will be r(t)=(1,2,1)+t(1,2,2).

describe all unit vectors orthogonal to both of the given vectors.
The unit vector orthogonal to both A and B is u = (0.23, -0.92, 0.15).
Given vectors:
A = (2, 3, 4)
B = (1, -1, 4)
A unit vector is a vector with a magnitude of 1. Two vectors are orthogonal if the angle between them is 90 degrees. In order to find unit vectors orthogonal to both A and B, we must first compute the cross product of A and B. The cross product of two vectors is a vector perpendicular to both of the given vectors and can be denoted by A × B.
The cross product of A and B is given by:
A × B = (3, -12, 2)
To normalize this vector and find the unit vector, we must divide the vector by its magnitude. The magnitude of the vector A × B is equal to the square root of the sum of the squares of its components. We can write this as:
|A × B| = √(3^2 + (-12)^2 + 2^2) = √(169) = 13
Therefore, the unit vector orthogonal to both A and B is given by:
A × B/|A × B| = (3/13, -12/13, 2/13)
This vector can also be written in terms of its unit components, as:
u = (0.23, -0.92, 0.15)

The probability of each possible outcome has been calculated and the most likely joe placed his pencil on point a of the hexagon below. is zero
The task provides a context to calculate discrete probabilities and represent them on a bar graph. It could also be used to create a class activity where students gather, represent, and analyze data, running simulations of the random walk and recording and then displaying their results.
If we denote by H an outcome of heads and by T and outcome of tails, then the possible outcomes for the four coin flips can be represented by a sequence of four letters, with each letter being either a T or an H. For example HHHH would represent the case where all four coin tosses come up heads. There are two choices for each letter and four letters so this gives 2^4=16possible outcomes.
To see more clearly why the two possibilities for the first toss need to be multiplied by the two possibilities for the second toss observe that each outcome, H or T for the first toss, leads to two possible outcomes when paired with the second toss: H leads to HH and HT while T leads to TH and TT. This reasoning for multiplying by two for each additional coin toss leads to 2^4 possibilities if the coin is tossed four times.
For f(6) to be zero, there need to be the same number of steps to the left as to the right. So there must be 3 heads and 3 tails. We can make a list of the possibilities. To simplify the list, we will list the possibilities for which tosses came up heads so that 123 will mean that the first, second, and third tosses were heads while the fourth
123,124,134,234.
There are four possibilities so the probability that f(4)=0 is 4/ 16.
A word is worthwhile regarding the way in which the possible ways three heads could occur was listed above. The list is long and so to avoid duplication and to make sure the list is complete a method is useful. The list above has been formed by choosing the smallest first number (this is why the first ten numbers in the list begin with a 1), then the smallest possible second number, and finally the smallest third number.
In order for f(4) to be one there would need to be one more occurrence of heads than tails. But this means that the total number of coin tosses would have to be odd: if n is any whole number then n+(n+1)=2n+1 is an odd number. Therefore the probability that f(4)=1 is 0. The argument for why f(4) can never equal 1 is essentially the same as the argument in ''Random Walk II'' for why it is not possible for f(5) to be equal to 2.
Finally for the probability that f(4)=4. This means that Scott must have moved in the positive direction after each of the six coin tosses so all six coin tosses must have been heads. So this can happen in only one way while there are 2^4=16 different possible outcomes for the four coin tosses so the probability that f(4)=4 is 1/16.
The probability of each possible outcome has been calculated and the most likely joe placed his pencil on point a of the hexagon below. is zero.

The probability of each potential result has been evaluated, and the most likely result is zero, where Joe set his pencil on point an of the hexagon.
The assignment gives you a context for computing discrete probabilities and visualizing them as bars. It might also be used to develop a lesson plan where students acquire, depict, and evaluate data, simulate the random walk, then record, analyze, and present their findings. The four coin flips' various outcomes can be represented by a string of four letters, each of which can be either a T or an H. If we signify by H an outcome of heads and by T an outcome of tails. For instance, the circumstance when all four coin tosses result in heads would be represented by HHHH. Each letter and the four letter combination has two options. so this gives [tex]2^4=16[/tex] possible outcomes.
For a clearer understanding of why the two possibilities for the first toss must be multiplied by the two possibilities for the second toss, consider the fact that each of the two possible outcomes for the first toss, H or T, leads to two additional outcomes when paired with the second toss: H leads to HH and HT while T leads to TH and TT. This reasoning for multiplying by two for each additional coin toss leads to [tex]2^4[/tex] possibilities if the coin is tossed four times.
There must be exactly as many steps to the left as there are to the right in order for f(6) to be zero. The result is that there must be three heads and three tails. A list of the possibilities can be created. To make the list shorter, we will list the possibilities for which tosses resulted in heads. For example, 123 would indicate that the first, second, and third tosses were all heads, but the fourth
123,124,134,234.
There are four possibilities so the probability that f(4)=0 is 4/ 16.
An explanation of how the potential causes of three heads were given above is important. The list is lengthy, thus a method is helpful to prevent duplication and ensure the list is full. The first 10 digits on the list above start with a 1, which was chosen as the smallest first number, followed by the smallest second number and, ultimately, the smallest third number.
There would have to be one more head than tail occurrences for f(4) to be one. However, this necessitates that the total number of coin tosses be odd: if n is any whole integer, then [tex]n(n+1)=2n+1[/tex] is an odd number. Consequently, there is no chance that f(4)=1 at all. Similar to the justification in "Random Walk II" for why f(5) cannot equal 2, the justification for why f(4) can never equal 1 is basically the same.
Finally, we have the likelihood that f(4)=4. This implies that Scott must have walked in the right direction after each of the six coin flips, proving that all six flips resulted in heads. Given that there are [tex]2^4=16[/tex] possible outcomes for the four coin flips, there is only one way that this may happen, making the chance that f(4)=4 1/16. The likelihood of each potential result has been evaluated, and the most likely value is zero.

The length of a basket is measured to be 13 inches, but the basket is actually 1 foot long. What is the percent error in the measurement?.
Percent error in the measurement is 8.3 % ( round to one decimal )
Percent of error show how big the error between measurement and actual value in comparison of actual value, and shown in percentage.
Simple formula to find percent of error is :
% error = | (T - E) / T | x 100%
Where :
T is actual value
E is estimated / measured value
From the question, we know following information :
1. Measured Value = 13 inches
--> E = 13 inches
2. Actual value = 1 foot. We know that 1 foot equal to 12 inches
--> T = 12 inches
% error = | (T - E) / T | x 100%
= | (12-13)/12 | x 100%
= | -1/12 | x 100%
= | -0.083 | x 100%

If the function of g is formed by applying the indicated sequence of
transformations to the given function f.
Find the equation of the function of g given that the graph of f(x) = x³ is
shifted 3 units up and 5 units to the left.
Step-by-step explanation:
up/down shifts are easy. they just indicate a constant change to the calculated y-values (result values) of f(x).
a shift up is therefore just adding a constant to f(x).
a shift down is just subtracting a constant from f(x).
in our case that would be f(x) + 3 = x³ + 3.
left/right shifts are more difficult to understand.
a shift to the left means that the same y-/result values happen as for f(x) also for g(x), just a bit "earlier" (to the left) on the x-axis.
a shift to the right means via the same principle the y-values for f(x) happen unchanged but "later" (to the right on the x-axis) for g(x).
so, 5 units to the left means that g(x) has the same y-value as f(x+5). f(x+5) happens 5 units earlier (at x).
and so, the full g(x) is
g(x) = f(x+5) + 3 = (x+5)³ + 3 =
= (x² + 10x + 25)(x + 5) + 3 =
= x³ + 5x² + 10x² + 50x + 25x + 125 + 3 =

The length of the rectangular garden will be 13 feet.
Let x be the length of the rectangular garden.
If the length of the garden is to be 5 feet longer than the width, then the expression for the width should be "x - 5".
If the area of the garden will be 104 square feet, then the equation for the area will be:
A = x(x - 5) = 104 square feet
Simplify the equation and solve for the value of x.
x² - 5x - 104 = 0
(x + 8)(x - 13) = 0
x = -8 ; x = 13
(choose the positive value since dimensions should always be positive)
Therefore, the length of the rectangular garden is 13 feet.

HELP PLEASEEE. WILL GIVE 15 POINTS
Answer:
PQ=17.088
Step-by-step explanation:
If M is the midpoint of PQ, then PM is half the length of PQ. So we cna find our answer by first finding PM.
Imagine a right angle triangle with PM as its hypotenuse. Since P(x,y)=(5,-15), and M(x,y)=(13,-18), we know that the length of the vertical side of this triangle is the difference between P and M's y (vertical) coordinates, and the length of the horizontal side of this triangle is the difference between P and M's x (horizontal) coordinates. This means the vertical side is equal to -15-(-18)=3 and the horizontal side is equal to 13-5=8. Since we know the lengths of the other two sides and PM is the hypotenuse, we can use pythagorus to find the length of PM:
PM = [tex]\sqrt{3^{2} +8^{2} } =\sqrt{9 +64 }=\sqrt{73} =[/tex]8.544
Since PM is half PQ, PQ=2(8.544)=17.088
Complete the equation of the line through
(-8,8) and (1,-10)
Use exact numbers.
Answer:
y = -2x-8
Step-by-step explanation:
1. (-8,8)
2. (1,-10)
first lets find the slope
m = y2-y1 / x2-x1
m = -10-8 / 1-(-8)
m = -18 / 9
m = -2
y = -2x+b
lets find b by plugging in point 2
-10 = -2(1)+b
-10 = -2+b
b = -8
our equation:
y = -2x-8

How do you fully simplify (3)/(2x+12) - (x-15)/(x^2-2x-48)?
Answer:
Step-by-step explanation:
4564. 2 75444214///4222.-112
The fully simplified form of the expression is [tex]\frac{3}{2x+12}-\frac{-3}{x-8} +\frac{4}{x+6}[/tex]
What do you mean by quadratic equation?A quadratic equation is a type of polynomial equation that has the general form ax^2 + bx + c = 0, where a, b, and c are coefficients and x is an unknown variable. The equation has two solutions, which can be found using the quadratic formula x = (-b ± √(b^2 - 4ac)) / 2a, where the ± symbol indicates that there are two possible solutions.
Quadratic equations are used to model a variety of real-world phenomena, such as the motion of objects under the influence of gravity, the path of a projectile, and the growth of a population over time. They are also used to describe the parabolic shape of curves and to solve optimization problems, such as finding the maximum or minimum value of a function
We can simplify the expression as follows:
[tex]\frac{3}{2x+12} =\frac{x-15}{x^{2} -2x-48}[/tex]
First, we'll simplify the denominators. To do this, we can factor the quadratic expression x² - 2x - 48:
x² - 2x - 48 = (x - 8)(x + 6)
Now we can rewrite the denominators:
[tex]\frac{3}{2x+12}-\frac{x-15}{(x-8)(x+6)}[/tex]
Next, we'll simplify the fraction in the second term using partial fraction decomposition:
[tex]\frac{x-15}{(x-8)(x+6)} =\frac{A}{x-8}+\frac{B}{x+6}[/tex]
where A and B are constants that we can find by multiplying both sides by (x - 8)(x + 6) and equating the numerators:
x - 15 = A(x + 6) + B(x - 8)
Expanding both sides:
x - 15 = Ax + 6A + Bx - 8B
Comparing coefficients:
-15 = Ax + 6A + Bx - 8B
1 = A + B
8B = Ax + 6A + 15
-6A = -15 - Ax - 8B
-6A = -15 - (A + B)x - 8B
-6A = -15 - x + 7x
-6A = -15 - x + 7x
-6A = -15 + 6x
Solving for A and B, we have:
A = -3
B = 4
So, the second term can be written as:
[tex]\frac{x-15}{(x-8)(x+6)} =\frac{-3}{x-8}+\frac{4}{x+6}[/tex]
Putting everything together, we have:
[tex]\frac{3}{2x+12} -\frac{x-15}{(x-8)(x+6)} =\frac{3}{2x+12}-\frac{-3}{x-8} +\frac{4}{x+6}[/tex]
which is the fully simplified form of the expression.

The slope of this line is m = 1.
An equation of this line is y = x.
How to calculate the slope of a line?In Mathematics, the slope of any straight line can be determined by using this mathematical equation;
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Based on the information provided, we can logically deduce the following data points on the line:
Points on x-axis = (0, 1).Points on y-axis = (0, 1).Substituting the given data points into the slope formula, we have the following;
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Slope (m) = (1 - 0)/(1 - 0)
Slope (m) = 1/1
Slope (m) = 1
At data point (1, 1), an equation of this line can be calculated by using the point-slope form as follows:
y - y₁ = m(x - x₁)
Where:
m represents the slope.x and y represents the data points.Substituting the parameters, we have the following:
y - y₁ = m(x - x₁)
y - 1 = 1(x - 1)
y = x - 1 + 1
y = x

The team is predicted to win 56.2% of its games this season.
What is probability?
By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. Because the favorable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1. The probability can also be expressed as in form of a percentage as we multiply it by 100.
It's the middle of a season, and Bill James has calculated the Pythagorean Winning Percentage (W%) of a team as .562.
To convert, the probability to percentage just multiply by 100 =.562*100
= 56.2%.
Hence The team is predicted to win 56.2% of their games this season.
