The value of the of expression that can be found by the data given in the question that is (g∘h)(-2) is quat to 16.
Composition of functions:
The composition of functions is an operation that combines two functions to create a new function. It is denoted by the symbol "[tex]\circ[/tex]" (a small circle).
If we have two functions, f(x) and g(x), the composition of f and g is written as (f∘g)(x), and it represents the result of applying the function g to x first and then applying the function f to the result.
To find the value of (g[tex]\circ[/tex]h)(-2), we need to evaluate the composition of functions g and h at the input value -2.
First, we evaluate h(-2):
h(-2) = (-2)² + 4 = 4 + 4 = 8
Next, we substitute the result of h(-2) into g(x):
g(8) = 2 * 8 = 16
Therefore, (g∘h)(-2) = 16.

for this utility function? 3) Is the MRS
x,y
diminishing, constant, or increasing in x as the consumer substitutes x for y along an indifference curve? 4) Will the indifference curve corresponding to this utility function be convex to the origin, concave to the origin, or straight lines? Explain.
The indifference curve corresponding to this utility function will be convex to the origin. This is because the utility function exhibits diminishing marginal returns for both goods. As the consumer increases the quantity of one good while keeping the other constant, the marginal utility derived from the additional unit of that good decreases. This diminishing marginal utility leads to convex indifference curves, indicating that the consumer is willing to give up larger quantities of one good for small increases in the other good to maintain the same level of satisfaction.
The assumption of 'more is better' is satisfied for both goods in this utility function because as the consumer increases the quantity of either good x or good y, their utility (U) also increases. The positive coefficients of x and y in the utility function indicate that more of each good is preferred.
The marginal rate of substitution (MRS) measures the rate at which a consumer is willing to exchange one good for another while maintaining the same level of utility. In this utility function, the MRSx,y is equal to 1.
The MRSx,y is diminishing in x as the consumer substitutes x for y along an indifference curve. This means that as the consumer increases the quantity of good x, they are willing to give up fewer units of good y to maintain the same level of satisfaction. The diminishing MRSx,y reflects a decreasing willingness to substitute x for y.

Use synthetic division and the Remainder Theorem to find P(a) .
P(x)=x⁴+3 x³-7 x²-9 x+12 ; a=3
Answer:
Step-by-step explanation:
To find P(a) using synthetic division and the Remainder Theorem, we can perform synthetic division with the given polynomial P(x) and the value of a = 3.
The coefficients of the polynomial P(x) are:
1, 3, -7, -9, 12
Using synthetic division, we set up the division as follows:
3 | 1 3 -7 -9 12
|__________
|
We bring down the first coefficient, which is 1, and then perform the synthetic division step by step:
3 | 1 3 -7 -9 12
|__________
| 3
|__________
6
____
-1
____
-12
____
0
The final result of the synthetic division gives us a remainder of 0.
According to the Remainder Theorem, if we divide a polynomial P(x) by (x - a), and the remainder is 0, then P(a) = 0.
Therefore, P(3) = 0.
In this case, plugging in a = 3 into the polynomial P(x), we find that P(3) = 3^4 + 3(3)^3 - 7(3)^2 - 9(3) + 12 = 81 + 81 - 63 - 27 + 12 = 84.
So, P(3) = 84.
Note: The Remainder Theorem states that if P(x) is divided by (x - a) and the remainder is zero, then (x - a) is a factor of P(x), and therefore, P(a) = 0.

CHALLENGE. Point K is between points J and L . If J K=x²-4 x, K L=3 x-2 , and J L=28 , write and solve an equation to find the lengths of J K and K L .
Step-by-step explanation:
We can use the fact that the sum of the lengths of J and is equal to the length of JK + KL = JL.
So, we have:
JK + KL = JL
Substituting the given values, we get:
(x^2 - 4x) + (3x - 2) = 28
Simplifying and solving for x, we get:
4x^2 - 8x - 26 = 0
Dividing by 2, we get:
2x^2 - 4x - 13 = 0
Using the quadratic formula, we get:
x = [4 ± sqrt(16 + 104)] / 4
x = [4 ± sqrt(120)] / 4
x = [4 ± 2sqrt(30)] / 4
x = 1 ± 0.5sqrt(30)
Note that we reject the negative solution for x, since length cannot be negative.
Therefore, the length of JK is:
JK = x^2 - 4x = (1 + 0.5sqrt(30))^2 - 4(1 + 0.5sqrt(30)) ≈ 5.185
And, the length of KL is:
KL = 3x - 2 = 3(1 + 0.5sqrt(30)) - 2 ≈ 3.46
Therefore, the lengths of JK and KL are approximately 5.185 and 3.46, respectively.

The factors (x + 9) and (x + 15) involve only addition and multiplication operations, the resulting polynomial has rational coefficients. Thus, the polynomial function P(x) = (x + 9)(x + 15) meets the given criteria.
A polynomial function with rational coefficients that has -9 and -15 as its roots can be constructed using the factored form of a polynomial. Let's call this polynomial P(x).
P(x) = (x + 9)(x + 15)
In this form, we have two linear factors: (x + 9) and (x + 15), which correspond to the given roots -9 and -15, respectively. Multiplying these factors together gives us the desired polynomial.
The roots of a polynomial equation are the values of x that make the equation equal to zero. By setting P(x) equal to zero, we obtain:
(x + 9)(x + 15) = 0
This equation is satisfied when either (x + 9) or (x + 15) is equal to zero. Therefore, the roots of P(x) = 0 are -9 and -15, as required.
Since the factors (x + 9) and (x + 15) involve only addition and multiplication operations, the resulting polynomial has rational coefficients. Thus, the polynomial function P(x) = (x + 9)(x + 15) meets the given criteria.

a pond contains 1120 l of pure water and an uknown amount of an undesirable chemical. water contaninig 0.01 kg of this chemical per liter flows into the pond at a rate of 6 l/h. the mixture flows out at the same rate, so the amount of water in the pond remains constant. assume that the chemical is uniformly distributed throughout the pond. let q(t) be the amount of chemical (in kg) in the pond at time t hours. (a) write a differential equation for the amount of chemical in the pond? at any time time (enter q for q(t): dqdt
Differential equation for the amount of chemical in the pond is dq/dt = (0.01 kg/l) * (6 l/h) - (q(t)/1120 kg) * (6 l/h). This equation represents the rate of change of the amount of chemical in the pond with respect to time.
The first term on the right-hand side of the equation represents the rate at which the chemical is flowing into the pond, which is 0.01 kg/l multiplied by the flow rate of 6 l/h. The second term represents the rate at which the chemical is flowing out of the pond, which is proportional to the current amount of chemical in the pond, q(t), and the outflow rate of 6 l/h divided by the total volume of the pond, 1120 kg.
To explain the equation further, the first term captures the input rate of the chemical into the pond. Since the concentration of the chemical in the incoming water is 0.01 kg/l and the water is flowing at a rate of 6 l/h, the product of these two values gives the rate at which the chemical is entering the pond.
The second term represents the outflow rate of the chemical, which is proportional to the current amount of chemical in the pond, q(t), and the outflow rate of 6 l/h divided by the total volume of the pond, 1120 kg. This term accounts for the removal of the chemical from the pond through the outflow of the water. By subtracting the outflow rate from the inflow rate, we can determine the net change in the amount of chemical in the pond over time.

The annual sales of the Hand & Foot Cream are increasing by 151,000 bottles per year. Based on the linear trend equation, the predicted annual sales for year 6 is 1,006,000 bottles.
According to the given linear trend equation F1 = 80 + 151, the constant term 80 represents the initial annual sales at the start of the trend. The coefficient of the independent variable t, which represents the number of years, is 151.
To determine whether the annual sales are increasing or decreasing, we look at the coefficient of t. Since the coefficient is positive (151), it indicates that the annual sales are increasing over time. The coefficient tells us that for every year that passes, the annual sales increase by 151,000 bottles. Therefore, the annual sales are experiencing positive growth.
To predict the annual sales for year 6, we substitute t = 6 into the equation. Plugging in the value, we have F6 = 80 + (151 * 6) = 80 + 906 = 986. Therefore, the predicted annual sales for year 6 is 986,000 bottles.
In conclusion, the annual sales of the Hand & Foot Cream are increasing by 151,000 bottles per year. Based on the linear trend equation, the predicted annual sales for year 6 is 986,000 bottles. This indicates that the product's popularity and demand are growing steadily.

The piecewise function f(x) has three defined cases.
For x < 0, the function is f(x) = x. This means that the graph is a straight line with a slope of 1 passing through the origin (0, 0) and extending to the left.
For x = 0, the function is f(x) = -1. This case corresponds to a single point (-1, 0) on the graph, where the line changes abruptly.
For x > 0, the function is f(x) = x. Again, the graph is a straight line with a slope of 1, but now extending to the right from the point (-1, 0).
To graph this function, we can plot the points (-1, 0) and (0, -1), and then draw a line passing through the origin (0, 0) and extending both to the left and right.

Answer:
To solve this expression, we'll follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) to simplify it step by step:
First, let's simplify the exponent: (3^10) = 59049
So, the expression becomes: 59049^0
Any number (except 0) raised to the power of 0 is always equal to 1.
Thus, 59049^0 = 1
Finally, we need to square the result: 1^2 = 1
Therefore, [(3^10)^0]^2 = 1^2 = 1.
((3 * 2) ^ 6)/(2 ^ 6) can be simplified as follows:
(6 ^ 6)/(64)
The value of 6 raised to the power of 6 is 46656, so the expression simplifies to:

Explain why a reflection of a matrix of points from a function table across the line y=x is equivalent to finding the inverse of the function.
Reflecting a matrix of points from a function table across the line y=x is equivalent to finding the inverse of the function because both operations involve interchanging the roles of the independent and dependent variables, resulting in the same set of points in reverse order
When reflecting a matrix of points from a function table across the line y=x, each point (x, y) is transformed into a new point (y, x). In other words, the x-coordinate becomes the y-coordinate, and the y-coordinate becomes the x-coordinate. This reflection is equivalent to interchanging the roles of the independent variable (x) and the dependent variable (y).
Finding the inverse of a function also involves interchanging the roles of the independent and dependent variables. The inverse function of a function f(x) is denoted as f^(-1)(x) and is defined such that f^(-1)(f(x)) = x and f(f^(-1)(x)) = x.
When we reflect the matrix of points across the line y=x, we are essentially transforming the original function f(x) into its inverse function f^(-1)(x). The inverse function swaps the x and y coordinates of each point, just like the reflection does.
Therefore, reflecting a matrix of points from a function table across the line y=x is equivalent to finding the inverse of the function because both operations involve interchanging the roles of the independent and dependent variables, resulting in the same set of points in reverse order.

If 4 x<24 , then x<6 .
Yes, if 4x < 24, then x < 6. In the given inequality, 4x < 24, we can divide both sides of the inequality by 4 to isolate x. This gives us x < 6, which means that any value of x that satisfies 4x < 24 will also satisfy x < 6.
To understand this, let's consider the original inequality. If 4x < 24, it means that the product of 4 and x is less than 24. Dividing both sides of the inequality by 4 gives us x < 6, which means that x is less than 6. This is because dividing a number by a positive value, in this case, 4, does not change the direction of the inequality. So, any value of x that makes the product of 4 and x less than 24 will also make x less than 6. Therefore, we can conclude that if 4x < 24, then x < 6.

Solve each equation. If necessary, round to the nearest thousandth.
4²ˣ = 10
The solution of the equation 4²ˣ = 10 is x = 0.316. We can solve the equation by first isolating the exponent. We have:
4²ˣ = 10
=> 2²ˣ = 5
Since 2⁵ = 32, we know that 2²ˣ = 5 when x = 2. However, we need to be careful because the equation 4²ˣ = 10 is also true when x = -2. This is because 4²⁻² = 4⁻² = 1/16 = 0.0625, which is also equal to 10 when rounded to the nearest thousandth.
Therefore, the two solutions of the equation are x = 0.316 and x = -2.
To check our solutions, we can substitute them back into the original equation. We have:
4²ˣ = 10

Quadrilateral WXYZ is a rectangle. Find each measure if m<1 = 30 . (Lesson 6-4 )
m<6
In a rectangle WXYZ with angle 1 measuring 30 degrees, angle 6 measures 150 degrees. Opposite angles in a rectangle are congruent, and adjacent angles are supplementary.
Since quadrilateral WXYZ is a rectangle, opposite angles are congruent. Therefore, m<1 = m<3 = 30 degrees.
In a rectangle, adjacent angles are supplementary, meaning their measures add up to 180 degrees. Angle 6 (m<6) is adjacent to angle 1 (m<1), so:
m<6 + m<1 = 180 degrees
Substituting the given measure m<1 = 30 degrees:
m<6 + 30 = 180
Subtracting 30 from both sides:
m<6 = 180 - 30
m<6 = 150 degrees
Therefore, m<6 measures 150 degrees in quadrilateral WXYZ.

A point on a line and its slope are given. Find the point-slope form of the equation of the line.
P = (6,6); m = 2
The point-slope form of the equation of the line is ____
(Use integers or fractions for any numbers in the equation.)
The point-slope form of the equation of the line with point P = (6,6) and slope m = 2 is y - 6 = 2(x - 6).
The point-slope form of a linear equation is given by y - y1 = m(x - x1), where (x1, y1) represents a point on the line, and m is the slope of the line.
In this case, the given point is P = (6,6) with coordinates (x1, y1) = (6,6), and the slope is m = 2. Plugging these values into the point-slope form equation, we have:
y - 6 = 2(x - 6)
This equation represents a line with a slope of 2 passing through the point (6,6). The equation can be further simplified by distributing 2 to the terms inside the parentheses:
y - 6 = 2x - 12
This form allows us to describe the equation of the line based on the given point and slope.

find an ordered triple $(x,y,z)$ of real numbers satisfying $x\le y\le z$ and the system of equations \begin{align*} \sqrt{x} \sqrt{y} \sqrt{z}
The ordered triple that satisfies the system of equations is (x, y, z) = (1, 2, 1).
To find an ordered triple (x, y, z) of real numbers satisfying the given system of equations, we can start by assigning values to two of the variables and solving for the remaining variable.
Let's assign x = 1 and y = 2. We can substitute these values into the first equation and solve for z:
√x√y√z = 2
√1√2√z = 2
√2√z = 2
√z = 1
Since z must be positive, we can square both sides of the equation:
z = 1
Therefore, one ordered triple that satisfies the system of equations is (x, y, z) = (1, 2, 1).

What is the sum of the solutions of |5-3 x|=x+1 ?
The sum of the solutions of the equation |5-3x| = x+1 is 8.
To find the solutions of the equation |5-3x| = x+1, we need to consider two cases: when the expression inside the absolute value is positive and when it is negative.
Case 1: 5-3x ≥ 0
In this case, the equation simplifies to 5-3x = x+1. By solving for x, we get x = 2.
Case 2: 5-3x < 0
In this case, the equation simplifies to -(5-3x) = x+1. By solving for x, we get x = 6.
Therefore, the solutions to the equation are x = 2 and x = 6. The sum of these solutions is 2 + 6 = 8. Thus, the sum of the solutions of the equation |5-3x| = x+1 is 8.

Let u = (-3, 4), v = (2,4) , and w= (4,-1) . Write each resulting vector in component form and find the magnitude
3u
The resulting vector 3u in component form is (x, y) = (-9, 12). The magnitude of 3u is 15. To find 3u, we multiply each component of vector u by 3.
u = (-3, 4)
Multiplying each component by 3, we get:
3u = (3 * -3, 3 * 4)
= (-9, 12)
Therefore, the resulting vector 3u in component form is (x, y) = (-9, 12).
To find the magnitude of 3u, we can use the formula:
|3u| = √(x² + y²)
Substituting the values x = -9 and y = 12, we have:
|3u| = √((-9)² + 12²)
= √(81 + 144)
= √(225)
= 15
Hence, the magnitude of 3u is 15.
