When the minimum volume of a clown is 60,000 cm³ and the volume of a car is 3 million cm³, 55 is an upper bound on the maximum number of clowns that can fit in a car. The correct answer is Option A.

Bounds are the maximum and minimum limits that are permitted, within which something can or must be performed. Bounds are used to refer to an acceptable range of values that provide safe operation or performance. In mathematics, a set of bounds can define the limits of the amount of things or objects.

The minimum volume of a clown is 60,000 cm³, so to fit 55 clowns in a car we need:

55 clowns × 60,000 cm³/clown = 3,300,000 cm³

This is lower than the volume of the car. Therefore, 55 is an upper bound on the maximum number of clowns that can fit in the car.

Answer:

0.18

Step-by-step explanation:

Given that:

P₁ = $10, P₂ = $20

From the tables Q₁ = 900, Q₂ = 800

Using midpoint method:

Percentage change in quantity = \(\frac{Q_2-Q_1}{(Q_1+Q_2)/2} *100\%=\frac{800-900}{(900+800)/2}*100\%= -11.76\%\\\)

Percentage change in price =

\(\frac{P_2-P_1}{(P_1+P_2)/2} *100\%=\frac{20-10}{(20+10)/2}*100\%= 66.67\%\\\)

Price of elastic demand = Percentage change in quantity/ Percentage change in price = -11.76% / 66.67% = 0.18

The Price of elastic demand is positive because we took the absolute value and elasticity are always positive

Therefore since Price of elastic demand < 1, the demand is inelastic in this interval.

This means that, along the demand curve between $10 to $20, if the price changes by 1%, the quantity demanded will change by 0.18%. A change in the price will result in a smaller percentage change in the quantity demanded. For example, a 10% increase in the price will result in only a 1.8% decrease in quantity demanded and a 10% decrease in the price will result in only a 1.8% increase in the quantity demanded

Answer:

B Supply will decrease, so equilibrium price will increase

there are less cars being made so the supply curve will shift to the left so the equilibrium price increases

The measure of the angle T made by the tangent CT and the secant AT is 45°.

Given is a circle, we need to find the angle T made by the tangent CT and the secant AT, also given, m arc ABC : m arc CDE = 3:1,

Let m arc ABC = 3x and m arc CDE = x

So,

We see that the arc ABE is a semicircle so m arc ABE = 180°,

Also,

m arc ABE = m arc ABC + m arc CDE

180° = 3x+x

4x = 180°

x = 45°

So,

m arc ABC = 135° and m arc CDE = 45°

Now using the properties of a circle,

We have.

m ∠T = 1/2 [m arc ABC - m arc CDE]

m ∠T = 1/2 [135° - 45°]

m ∠T = 45°

Hence the measure of the angle T made by the tangent CT and the secant

AT is 45°.

The derivative of f(x) = x^2sin(x) is (2xsin(x)) + (x^2*cos(x)). The correct formula for finding the derivative of the product of two functions is (fg)' = f'g + fg'.

This formula is known as the product rule in calculus and is widely used to differentiate a function that is the product of two other functions.

To use this formula to find the derivative of a specific function, we must first identify the two functions that make up the product. Once we have identified these functions, we can apply the product rule by taking the derivative of the first function times the second, plus the derivative of the second function times the first.

For example, let's say we want to find the derivative of the function f(x) = x^2*sin(x). In this case, we can identify the two functions as f(x) = x^2 and g(x) = sin(x). Applying the product rule, we get:

(fg)' = f'g + fg'

= (2xsin(x)) + (x^2cos(x))

Therefore, the derivative of f(x) = x^2sin(x) is (2xsin(x)) + (x^2*cos(x)).

Answer:

$1.41

Step-by-step explanation:

0.20 * 5.8 ounces = $1.16

0.25 * 1.16 = $1.41

The mail  weighing 6.8 ounces cost 145 cents

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given here, the first ounce cost 25 cents and all subsequent ounces or parts of an ounce cost 20 cents each

therefore cost of the first ounce = 25

        and cost of 5.8 ounces = 20× 6

                                                = 120 cents

thus total cost is 120+25 =145 cents

There are a total of 70 lattice paths that start at (2, 2) and end at (10, 10).

To find the number of lattice paths between two points, you can use the formula:
n! / (k! * (n-k)!)
In this case, the total number of steps needed to get from (2, 2) to (10, 10) is 8 steps to the right and 8 steps up, for a total of 16 steps. So n = 16.

The number of steps in one direction (either right or up) is 8, so k = 8.
Plug in these values to the formula:
16! / (8! * (16-8)!)
= 16! / (8! * 8!)
= 20922789888000 / 40320 * 40320
= 70

So there are 70 lattice paths between (2, 2) and (10, 10).

Step-by-step explanation:

There is no definitive answer to the proportion of early-twenty-first-century men who finished school, left home, become financially independent, married, and had a child by age 30.

In terms of finishing school, in 2016, the U.S. Census Bureau estimated that 88.6% of males aged 25 and older were high school graduates, while 33.4% had attained a bachelor's degree or higher. As for financial independence, a 2019 report by the St. Louis Federal Reserve Bank found that the percentage of 25-year-olds who earned more than their parents did at the same age has declined since 1970.

In terms of marriage, a 2017 report by the Pew Research Center found that the median age for men getting married for the first time was 29, up from 23 in 1960. Finally, regarding fatherhood, a 2018 report by the National Center for Health Statistics found that the mean age of first-time fathers in the United States was 31.1. However, it is important to note that these statistics and studies do not provide a complete picture of the proportion of men who have accomplished all these factors by age 30.

To find the the hypotenuse of a right triangle, you use the Pythagorean Theorem:

\( {a}^{2} + {b}^{2} = {c}^{2} \)

In the formula above though, c represents the hypotenuse instead of a.

Step-by-step explanation:

part1

the mean value is

(87+100+94+79+92+100+95+83+89+99+100+91+89+95+100+93+96+83) / 18

= 1665 / 18 = 92.5

First, you need to graph all given points in the table, that way you will be able to determine the end behavior.

Remember, the end behavior of a function is the behavior of f(x) as x approaches to positive infinity and negative infinity.

So, based in the graph, we can say that as x approaches to positive infinity, f(x) approaches to negative infinity, and as x approaches to negative infinity, f(x) approaches to negative inifinity. In other words, in either case, f(x) always approaches to negative infinity.

Therefore, the right answer is the last choice.

Answer:

As x → ∞, f(x) → –∞, and as x → –∞, f(x) → –∞

Answer:

The second number is the smallest of the three numbers with

value n = 16.

Step-by-step explanation:

Let n represent the second number, then the first number is 2n and the third number is 4n.

so

\(n+2n+4n=112\)

Solving for n

\(n+2n+4n=112\)

\(7n=112\)

\(\frac{7n}{7}=\frac{112}{7}\)

\(n=16\)

As n = 16 is the second number.

The first number = 2n = 2(16) = 32

The third number = 4n = 4(16) = 64

Therefore, the second number is the smallest of the three numbers with value n = 16.

For the exponential equation, having variable x as superscript equation has solution as,

\(x=-5,2\)

According to the equality for exponential equation property, when the bases of both side of a equation is same, then the exponents of both the terms must be equal.

The equation given in the problem is,

\(12^{x^2+5x-4}=12^{2x+6}\)

In the given equation, the base of both side is equal. For the equal base, the exponents of them can be equate as,

\({x^2+5x-4}={2x+6}\)

Arrange all the terms one side of the equation as,

\({x^2+5x-4}-{2x-6}=0\)

Solve it further as,

\({x^2+3x-10}=0\)

To solve the above quadratic equation, use the split the middle term method as,

\({x^2-2x+5x-10}=0\\x(x-2)+5(x-2)=0\\(x-2)(x+5)=0\)

y = -1/3x + 1

y = -2x - 3

We can compare the equations to the graphs and see which graph represents the intersection point of the two equations.

The first equation, y = -1/3x + 1, has a negative slope (-1/3) and a y-intercept of 1.

The second equation, y = -2x - 3, also has a negative slope (-2) and a y-intercept of -3.

Based on the slopes and y-intercepts, we can identify the correct graph by finding the point where the two lines intersect.

Unfortunately, since the graphs are not provided, I am unable to determine which specific graph shows the solution to the system of linear equations. I recommend referring to the graph representation of the equations and identifying the intersection point to determine the correct graph.

(a) To prove that a continuous preference relation is homothetic if and only if it can be represented by a utility function that is homogeneous of degree one, we need to show the two-way implication. If a preference relation is homothetic, it implies that there exists a utility function that is homogeneous of degree one to represent it. Conversely, if a utility function is homogeneous of degree one, it implies that the preference relation is homothetic.

(b) The result mentioned in the lecture slides states that any preference relation represented by a utility function that is homogeneous of any degree is homothetic.
