why do high interest rates so adversely affect the demand for housing and yet have so little influence on the demand for pizzas?

ANSWER:

18

STEP-BY-STEP:

To find the maximum value of P, we need to evaluate P at each vertex.

P(0,0)=3(0)+2(0)=0+0=0

P(0,22/3)=3(0)+2(22/3)=0+44/3=44/ 3

Now

P(16/5,0)=3(16/5)+2(0)=48/5+0=48/ 5

P(2,6)=3(2)+2(6)=6+12=18

Therefore, the maximum value of P is *18* when x = *2* and y = *6*.

Answer:

18

Step-by-step explanation:

To find the maximum value of p, substitute the value of x and the value of y of each vertices in the equation and then compare the results

p = 3x + 2y

For (0,0)

p = 3(0) + 2 (0)

For (0,7.3)

p = 3(0) + 2 (7.3) = 0

For (2,6)

p = 3(2) + 2(6) = 18

For (3.2,0)

p = 3(3.2) + 2(0) = 9.6

therefore the maximum value of p = 18

Amelia paid a total fine of £1.44 for returning the DVD 16 days overdue.

To calculate the total fine paid by Amelia, we need to determine the number of days the DVD was overdue and then multiply that by the fine rate.

The rental period for the DVD is from 26 November to 12 December. To find the number of days overdue, we subtract the due date from the actual return date:

12 December - 26 November = 16 days

Since the fine rate is 9p per day, we multiply the number of days overdue by the fine rate:

16 days × £0.09/day = £1.44

Therefore, Amelia paid a total fine of £1.44 for returning the DVD 16 days overdue.

Answer: c = 10, d = 7

Step-by-step explanation:

To solve this system using the linear combination method, we want to eliminate one of the variables, either c or d, by adding or subtracting the two equations. One way to do this is to add the two equations together, which will cancel out the d terms:

(c + d) + (c - d) = 17 + 3

2c = 20

c = 10

Now we can substitute this value of c into either equation to solve for d:

c - d = 3

10 - d = 3

d = 7

Therefore, the solution to the system is:

c = 10, d = 7.

Answer:

c=10 and d=7

Step-by-step explanation:

Use linear combination to solve the following system of equations.

Linear combination is synonymous with the method of elimination. The goal of elimination is to "eliminate" one of the variables so that we may solve for the other.

[tex]\left\{\begin{array}{ccc}c+d=17\\c-d=3\end{array}\right[/tex]

Notice how the "d" term has opposite signs in the system. We can add these two equations together to "eliminate" d.

[tex](c+d=17)+(c-d=3)=\boxed{2c=20}\\\\\therefore \boxed{\boxed{c=10}}[/tex]

We now know what "c" equals, plug this value into either of the equations and solve for "d."

[tex]c=10\\\\\Longrightarrow 10+d=17\\\\\therefore \boxed{\boxed{d=7}}[/tex]

Thus, the system is solved. c=10 and d=7.

The equation is given, N(a) = 2.925 sin ( 3.65 ) + 12.18, which models the number of hours of daylight in New York City d days after March 21, 2010.

To solve the equation 11.5 = 2.925 sin (27 d) + 12.18 over the interval [0°, 720°), we need to isolate the sine function on one side of the equation.

Subtracting 12.18 from both sides, we get:
-0.68 = 2.925 sin (27 d)
Dividing both sides by 2.925, we get:
sin (27 d) = -0.2333
To find d, we need to use the inverse sine function ([tex]sin^{-1}[/tex]) on both sides:
27 d = [tex]sin^{-1}[/tex] (-0.2333)
Using a calculator, we find that [tex]sin^{-1}[/tex] (-0.2333) = -13.5° or -0.235 radians (rounded to three decimal places).
Dividing both sides by 27, we get:
d = -0.0087 radians / 27
d = -0.00032 radians (rounded to five decimal places)
To make sense of this answer in the context of the problem, we need to convert radians to days.
One complete cycle of the sine function occurs over 360 degrees or 2π radians. Therefore, over the interval [0°, 720°), there are two complete cycles or 4π radians.
To find the number of days, we can set up a proportion:
4π radians = 365 days - 80 days (March 21 to June 9)
Solving for one radian, we get:
1 radian = (365 - 80) days / 4π
1 radian ≈ 71.3 days
Substituting this value, we get:
d = -0.00032 radians x 71.3 days/radian
d ≈ -0.023 days

The given statement is "In determining the size of hail stones, weather spotters should report the longest dimension of the largest hail stone"

This statement is False because meteorologists ought to report the hail stones' diameter in millimeters rather than their longest dimension.

The longest dimension is the longest line member between the two points of the hailstone, while the periphery is the longest distance between the two points. The standard measurement utilized by meteorologists is the periphery, which is a more accurate measurement of the size of the hail gravestone.

This is because the hailstone size could be used as an indicator of the wind speed and the height of the storm where it formed. The National Weather Service uses size criteria to issue various hail size warnings.

Answer:

31.40 inches

Step-by-step explanation:

The circle has a radius of 5 inches (as the radius is drawn from the center to the point labeled 5 inches).

Pi (π) = 3.14

Circumference = 2 * pi * Radius

Substitute the radius of 5 inches: Circumference = 2 * 3.14 * 5

= 31.40 inches

So the circumference of the full circle is 31.40 inches.

The other options do not match the given radius of 5 inches and the formula for circumference.

Hence, the correct option is:

31.40 inches

The greatest possible number of different values of all 30 student heights is 30.

Let the heights of students R, S, and M be r, s, and m, respectively. Then we have:

r = (s + m + r) / 3

2r = s + m

Similarly, we have:

s = (r + m + s) / 3

m = (r + s + m) / 3

Simplifying these two equations gives:

2s = r + m

2m = r + s

Adding all three equations, we get:

3r + 3s + 3m = 2r + 2s + 2m

r + s + m = 0

This means that the sum of all 30 student heights is 0.

Then the smallest possible sum of 30 distinct integers is 1 + 2 + ... + 30 = 465, and the largest possible sum is 465 + 29 + 28 + ... + 1 = 930.

We can then assign each of these 30 heights to a different student, with the additional condition that for each student R, there exist students S and M (all three are different students) such that the height of student R equals the average height of all three students.

Therefore, the greatest possible number of different values of all 30 student heights is 30.

To determine where the function is concave down, we need to find the values of x for which the second derivative is negative. Using the quadratic formula, we find that the roots of the second derivative are x=1 and x=4/5. Thus, the function is concave down for x values between 1 and 4/5.

To find whether a function is concave up or down, we need to look at its second derivative. If the second derivative is positive, the function is concave up. If the second derivative is negative, the function is concave down. In this case, we have found that the second derivative is 60x^2-144x+48. To find where the function is concave down, we need to find the values of x for which this second derivative is negative. We can do this by finding the roots of the quadratic equation 60x^2-144x+48=0. Using the quadratic formula, we find that the roots are x=1 and x=4/5. Thus, the function is concave down for x values between 1 and 4/5.

In college basketball, a "1 and 1" refers to a situation where a player is awarded one free throw and if they make that shot, they are awarded a second free throw.

We can find the PMF (probability mass function) of the number of points scored in a "1 and 1" situation given that any free throw goes in with probability p, independent of any other free throw.

Let Y denote the number of points scored in a "1 and 1" situation. There are three possible outcomes for Y: the player makes both free throws and scores 2 points, the player makes the first free throw but misses the second and scores 1 point, or the player misses the first free throw and scores 0 points.

The probability of making both free throws is p * p = p^2, since the two free throws are independent. The probability of making the first free throw but missing the second is p * (1 - p), and the probability of missing the first free throw is (1 - p). Thus, the PMF of Y is:

P(Y = 2) = p^2
P(Y = 1) = 2p(1-p)
P(Y = 0) = (1-p)^2

We can see that the PMF of Y follows a binomial distribution with n = 2 and p = the probability of making a free throw.

This distribution tells us the probability of obtaining a certain number of successes in a fixed number of independent trials, which is the same as the probability of scoring a certain number of points in a "1 and 1" situation.

This PMF can be useful for coaches and players to understand the probabilities of scoring in different scenarios and to make strategic decisions during games.

The range of this function can be represented using the interval [-1,1]. However, if we have a function h(x) = x^3, we know that the output values can take on any real number, so the range of this function can be represented using the interval (-∞, ∞).

Interval notation is a shorthand way of representing a range of numbers using brackets and parentheses. For example, the interval [0,1] represents all real numbers between 0 and 1, including 0 and 1 themselves. The interval (0,1) represents all real numbers between 0 and 1, excluding 0 and 1 themselves.

To represent the domain of a function using interval notation, we consider the set of all input values for which the function is defined. For example, if we have a function f(x) = x^2, we know that this function is defined for all real numbers. Therefore, the domain of this function can be represented using the interval (-∞, ∞).

To represent the range of a function using interval notation, we consider the set of all output values that the function can take. This can be a bit trickier, as some functions may take on a continuous range of values, while others may only take on a finite set of values. For example, if we have a function g(x) = sin(x), we know that the output values will always be between -1 and 1. Therefore, the range of this function can be represented using the interval [-1,1].

The statement "If B = [tex]PDP^{-1}[/tex] with P an orthogonal matrix and D a diagonal matrix, then B is a symmetric matrix" is true because If B = [tex]PDP^{-1}[/tex] with P an orthogonal matrix and D a diagonal matrix, then B is a symmetric matrix.

For a matrix to be symmetric, it should be equal to its transpose. Using the given equation, we have:

B^T = ([tex]PDP^{-1}[/tex])^T = (P^-1)^T D^T P^T

Since P is an orthogonal matrix, P^T = P^-1, and we can simplify the above equation as:

There are (n-1)! ways to permute n-1 elements.

What is algebra?

Algebra is a branch of mathematics that deals with mathematical operations and symbols used to represent numbers and quantities in equations and formulas.

In order to prove that a subset H of a group G is a subgroup of G, we need to show that H satisfies the three conditions of a subgroup:

Closure: for any a, b in H, the product ab is also in H.

Identity: H contains the identity element of G.

Inverses: for any a in H, the inverse of a in G is also in H.

Let H be the subset of S5 consisting of all permutations that fix the element 1. In other words, H consists of all permutations that map 1 to 1. We will show that H is a subgroup of S5.

Closure: Let a and b be two permutations in H. Then a(1) = 1 and b(1) = 1. Therefore, (ab)(1) = a(b(1)) = a(1) = 1. Hence, ab fixes 1 and is in H.

Identity: The identity permutation e always fixes 1. Therefore, e is in H.

Inverses: Let a be a permutation in H. We need to show that [tex]a^-1[/tex] is also in H. Since a fixes 1, we know that [tex]a^{-1}[/tex] also fixes 1. Moreover, since a is a bijection, we know that [tex]a^{-1}[/tex] is also a bijection. Therefore, [tex]a^{-1}[/tex] is a permutation of S5 that fixes 1, and hence, [tex]a^{-1}[/tex] is in H.

Since H satisfies the three conditions of a subgroup, we can conclude that H is a subgroup of S5.

How many elements are in H? We can count the number of elements in H by counting the number of ways we can permute the remaining four elements. There are 4! = 24 ways to permute four elements. Therefore, there are 24 elements in H.

Is this argument valid when 5 is replaced by any n? Yes, the argument is valid for any n. We can define H as the set of permutations in Sn that fix the element 1. The same three conditions hold, and we can conclude that H is a subgroup of Sn.

How many elements are in H when 5 is replaced by any n?
There are (n-1)! elements in H. We can count the number of elements in H by counting the number of ways we can permute the remaining n-1 elements. There are (n-1)! ways to permute n-1 elements. Therefore, there are (n-1)! elements in H.

The inverse Laplace transform of the function i(s) = (β^2)/(s^2 + β^2) is given by f(t) = β sin(βt).

The Laplace transform is a mathematical technique used to solve differential equations by transforming them from the time domain to the frequency domain. The inverse Laplace transform is then used to transform the solution back from the frequency domain to the time domain.

In this case, the Laplace transform of the function i(t) is given by I(s) = β^2/(s^2 + β^2). To find the inverse Laplace transform, we use the partial fraction decomposition technique to break down the function into simpler terms.

We can rewrite I(s) as I(s) = β^2/[(s + iβ)(s - iβ)]. Using partial fraction decomposition, we can express I(s) as I(s) = A/(s + iβ) + B/(s - iβ), where A and B are constants to be determined.

Solving for A and B, we get A = B = β/2i. We can now use the inverse Laplace transform table to find the inverse Laplace transform of each term.

The inverse Laplace transform of A/(s + iβ) is β/2 e^(-iβt), and the inverse Laplace transform of B/(s - iβ) is β/2 e^(iβt). Adding these two terms together gives us the final solution of f(t) = β sin(βt).

where:

A = final amount

P = principal amount (initial investment)

r = annual interest rate (as a decimal)

n = number of times the interest is compounded per year

t = number of years

In this case, we have:

P = $84,410

r = 15% = 0.15

n = 1 (compounded annually)

t = 4

Substituting these values into the formula, we get:

A = $84,410(1 + 0.15/1)^(1*4)

In Mathematics, the vertex form of a quadratic function is represented by the following mathematical equation:

f(x) = a(x - h)² + k

Where:

Based on the information provided about the y-intercept and x-intercepts, we can write the quadratic function and determine the value of "a" as follows:

f(x) = (x + 2)(x + 5)

f(x) = x² + 2x + 5x + 10

f(x) = x² + 7x + 10

f(x) = a(x² + 7x + 10)

-4 = a(0² + 7(0) + 10)

-4 = 10a

a = -4/10

         = (y/54)∑x=1 to 3 x

         = (y/54)(1+2+3)
