g if k < n - r, the value of max value(r, 0, k) should be the larger of two expressions. one of these expressions has -1 as the second parameter to maxvalue. what is it?

Answers

The larger of the two expressions is maxvalue(r, n - k - r, k).

The expression with -1 as the second parameter to maxvalue is maxvalue(n-k-r, -1, k).

To see why this is the case, let's consider the definition of maxvalue(r, a, b). This function returns the maximum value among r, a, and b.

Now, suppose that k < n - r. Then, we have:

n - k - r > n - (n - r) - r = r

This means that n - k - r is greater than r, so maxvalue(r, n - k - r, k) will return either n - k - r or k, whichever is greater.

On the other hand, since -1 is less than any non-negative integer, we have:

-1 < 0 <= r

Therefore, maxvalue(r, -1, k) will return either r or k, whichever is greater.

Since r is non-negative, we have:

maxvalue(r, -1, k) = max(r, -1, k) = max(r, k)

So, the larger of the two expressions is maxvalue(r, n - k - r, k).

It is important to understand these terms in order to have a solid foundation in mathematics.

1. Circular permutation - an ordering of elements in a circle.
In a circular permutation, the arrangement of items is considered in a circular fashion rather than in a linear order. The number of circular permutations for 'n' elements can be calculated using the formula (n-1)!.

2. Factorial - the product of all the natural numbers from an integer down to one.
Factorial, denoted by the symbol '!', represents the product of all the positive integers from a given integer down to one. For example, 5! = 5 × 4 × 3 × 2 × 1 = 120.

3. Series - the indicated sum of the terms of an associated sequence.
A series is the sum of the terms in a given sequence, often represented by the summation symbol Σ. For example, the sum of the first 'n' natural numbers is represented as Σ(i=1 to n) i = n(n+1)/2.

4. Permutation - an order of elements of a set.
A permutation refers to the arrangement of elements in a specific order within a set. The number of possible permutations for a set of 'n' elements, taken 'r' at a time, can be calculated using the formula n!/(n-r)!.

What is the approximate carrying capacity of the
population?

In which year, did the population reach the carrying capacity?

About how many years did it stay at carrying capacity?

Answers

Answer:

The carrying capacity of a population refers to the maximum number of individuals that a particular ecosystem can sustainably support over the long-term. It is affected by factors such as the availability of resources like food, water, and shelter, as well as disease, predation, and other environmental factors.

The carrying capacity of a population can vary over time and depends on many different variables, including the species in question, the environment it lives in, and the management practices that are in place. Therefore, it is not possible to determine the approximate carrying capacity of a population without specific details about the particular species and ecosystem in question.

Similarly, it is impossible to determine when a population reached its carrying capacity or how long it stayed there without specific information about the population and its environment. Population data over time can help to estimate changes in population size and to understand how it may have been impacted by different factors, but a detailed analysis of the specific ecosystem and species is required to make accurate predictions about carrying capacity and population dynamics.

O The graphs of the equations intersect each other at two places.

Answers

Note that the system of graphs has two y-intersects hence the two solutions. Note tht in the graph there ar etwo parabolas.

What is a y-intercept?

A y-intercept, also known as a vertical intercept, is the location where the graph of a function or relation meets the coordinate system's y-axis. This is done in analytic geometry using the usual convention that the horizontal axis represents the variable x and the vertical axis the variable y. These points fulfill x = 0 because of this.

Replace x in the equation with 0 and then solve for y, keeping in mind that the y-intercept always has an associated x-value of 0. Finding the value of y at x=0 on a graph will reveal the y-intercept. The graph's intersection with the y-axis occurs at this location.

#9Change from standard form to vertex formy= -xÂ²+4x-1

Answers

So the vector form of the equation is: y = -1(x - 2)² + 3.

To convert from standard form to vertex form, we complete the square by following these steps:

Factor out the coefficient of the x-squared term:

y = -x² + 4x - 1

= -1(x² - 4x) - 1

To complete the square inside the parentheses, add and subtract the square of half of the coefficient of the x-term (-4/2)^2 = 4:

y = -1(x² - 4x + 4 - 4) - 1

Simplify the expression inside the parentheses by factoring a perfect square:

y = -1((x - 2)² - 4) - 1

Distribute the -1 and simplify:

y = -1(x - 2)² + 3

Therefore, the vertex of the parabola is at (2, 3), and the negative coefficient of the x-squared term means that the parabola opens downwards.

Misha has a cube and a right-square pyramid that are made of clay. She placed both clay figures on a flat surface.
Select each box in the table that identifies the two-dimensional-plane sections that could result from a vertical or horizontal slice through each clay figure.

NEED ANSWER ASAP (THANKS)

Answers

The cube results in a square two-dimensional-plane section when slices horizontally or vertically.

The square right pyramid results in a square when sliced horizontally and a triangle when sliced vertically.

A cube has 6 faces which are all squares.

So when a cube is slice either parallel to the base or perpendicular to the base, the resulting section will be a square.

Whereas, a right square pyramid has a base square and 4 triangular faces joining at a common point.

So when the pyramid is cut vertically, it results in a triangle and when it cuts horizontally, it results in a square.

Hence the cube results in a square in either slices and right square pyramid results in a square or triangle.

Answers

If Nasim invests money in an account paying a simple interest of 1. 3% per year and he invests $70 and no money will be added or removed from the investment, the amount he will have in one year is 70 dollars and 91 cents

Simple interest refers to the interest that is calculated on the original amount or the principal. Simple interest is calculated by:

Interest = P * r * t

where P is the principal

r is the rate of interest (in decimal)

t is the time

Given in the question,

P = $70

r = 1.3% = 0.013

t = 1 year

Interest = 70 * 0.013 * 1

Answer: To find the surface area of a cylinder, we need to add the areas of the top and bottom circles to the lateral surface area (the curved surface that connects the circles).

1.) Given that the diameter (d) of the cylinder is 10m and the height (h) is 8m.

First, let's find the radius of the cylinder (r):

r = d/2 = 10m/2 = 5m

Then, we can find the surface area of the cylinder:

The area of each circle is given by A = πr^2

A(top and bottom circles) = 2π(5m)^2 = 2π(25m^2) = 50πm^2

The lateral surface area is given by A = 2πrh

A(lateral) = 2π(5m)(8m) = 80πm^2

The total surface area is the sum of the areas of the top and bottom circles and the lateral surface area:

A(total) = A(top and bottom circles) + A(lateral)

A(total) = 50πm^2 + 80πm^2

A(total) = 130πm^2

Therefore, the surface area of the cylinder is 130π square meters (or approximately 408.4 square meters if you round to one decimal place).

This statement is false. If K(t) = 0 for all t, it means that the curvature of the curve at any point is zero.

This does not necessarily imply that the curve is a straight line. A curve can have zero curvature at some or all points and still not be a straight line, for example, a circle.

In reference to line items, how many permutations are possible with the letters "ABC"?

Answers

So there are 6 permutations possible with the letters "ABC". These are: ABC, ACB, BAC, BCA, CAB, CBA.

Permutations are a way of arranging objects in a specific order. The number of permutations of a set of n distinct objects is given by n!, where n! denotes the factorial of n.

In the case of the letters "ABC", there are three distinct objects: A, B, and C. Therefore, the number of permutations possible with these letters is:

3! = 3 x 2 x 1 = 6

This means that there are 6 possible ways of arranging the letters "ABC" in a specific order. These permutations are:

ABC

ACB

BAC

BCA

CAB

CBA

To see why there are 6 possible permutations, consider the first position. There are three letters to choose from, so there are three possible choices for the first position. Once the first letter is chosen, there are two letters left to choose from for the second position. Finally, there is only one letter left to choose from for the third position. Therefore, the total number of permutations is:

3 x 2 x 1 = 6

In summary, the number of permutations of a set of n distinct objects is given by n!, and in the case of the letters "ABC", there are 3! = 6 possible permutations: ABC, ACB, BAC, BCA, CAB, and CBA.

what is the greatest three-digit positive integer n for which the sum of the first n positive integers is not a divisor of the product of the first n positive integers? (2019 amc 10a problem 9) (a) 995 (b) 996 (c) 997 (d) 998 (e) 999

Answers

The largest three-digit positive integer n for which the sum of the first n positive integers is not a divisor of the product of the first n positive integers is 995.

We have,

To solve this problem, let's consider the sum and the product of the first n positive integers separately.

The sum of the first n positive integers can be expressed as:

S = 1 + 2 + 3 + ... + n = (n(n+1))/2.

The product of the first n positive integers can be expressed as:

P = 1 x 2 x 3 x ... x n = n!.

We want to find the largest three-digit positive integer n for which S is not a divisor of P.

Since P = n! grows faster than S = (n(n+1))/2, we need to find a value of n where P is not divisible by S.

By observing the answer choices, we can start from the largest answer choice and work our way down until we find a value where P is not divisible by S.

Let's test the values of n given in the answer choices:

For n = 999:

P = 999! and S = (999(999+1))/2 = 499500.
