4370 cannot be represented as a sum of any two squares, but 1885 and 3185 can be written as a sum of two squares.

To determine which of the numbers 4370, 1885, 3185 can be represented as a sum of any two squares, we need to check if they can be expressed in the form of a^2 + b^2, where a and b are integers.

For 4370, we can start by checking the squares of integers up to the square root of 4370, which is approximately 66. Since 4370 is not a perfect square, we can check for all pairs of integers up to 66 and see if their sum of squares equals 4370. After checking all possibilities, we find that there are no two squares that add up to 4370.

For 1885 and 3185, we can repeat the same process and find that both of them can be represented as the sum of two squares. Specifically, 1885 can be written as 34^2 + 17^2 and 3185 can be written as 47^2 + 36^2.

The difference between this problem and ps4, problem 4 is that in ps4, problem 4, we were asked to find all possible pairs of integers a and b such that a^2 + b^2 = 2021. In this problem, we are asked to determine which of the given numbers can be represented as a sum of any two squares.

In summary, 4370 cannot be represented as a sum of any two squares, but 1885 and 3185 can be written as a sum of two squares.

Notation refers to a system of symbols or characters used to represent something. In the context of computational complexity theory, notation is used to describe the complexity of algorithms and problems. In particular, it is used to describe the complexity of polynomial time reductions between problems. A polynomial time reduction from problem A to problem B means that there exists an algorithm that can transform an instance of problem A into an equivalent instance of problem B in polynomial time. If there is no polynomial time reduction from problem A to problem B, we say that there is no polynomial time reduction exist from A to B. Therefore, the correct option is "it means that there is no a polynomial time reduction exist from a to b."

It means that there exists a polynomial time reduction from A to B.

In this context, a polynomial time reduction is a method of transforming one problem (A) into another problem (B) using a process that takes polynomial time. The notation indicates that there is an efficient algorithm for converting A to B, so if we can solve problem B efficiently, we can also solve problem A efficiently.

Step-by-step explanation:

f(g(-4)) = 3(-4)^2 -2(-4)

f(g(-4)) = 56

g(f(2)) = + 3 ?

g(f(2))= 3 ???

(I guess you didn't write the whole question, all you have to do is to replace "x" with the given value, in this case for g(f(2)) the given value is 2)

So the final expression is: (change in y/y) = n (change in a/a).

We can start by taking the natural logarithm of both sides of the equation:

ln(y) = ln(aⁿ)

Using the rule that ln(aⁿ) = n ln(a), we can simplify this to:

ln(y) = n ln(a)

Next, we can take the derivative of both sides with respect to a:

d/d(a) ln(y) = d/d(a) (n ln(a))

Using the chain rule, we can simplify the right-hand side to:

d/d(a) ln(y) = n (1/a)

Now, we can multiply both sides by a/y:

a/y * d/d(a) y = n(a/y) * (1/a)

Simplifying, we get:

dy/y = n da/a

if y is not the zero vector, then there exists a non-zero vector v in the original vector space that is orthogonal to y.

If y is in a subspace W as well as its orthogonal complement Wâ¥, then y is orthogonal to every vector in W as well as every vector in Wâ¥. Since W and W⥠are complements, every vector in the original vector space can be written uniquely as the sum of a vector in W and a vector in Wâ¥. Since y is orthogonal to every vector in W and every vector in Wâ¥, it must be orthogonal to every vector in the original vector space.

Therefore, if y is not the zero vector, then there exists a non-zero vector v in the original vector space that is orthogonal to y. But then v would belong to both W and Wâ¥, which is impossible since W and W⥠are orthogonal complements and their intersection is only the zero vector.

Based on the information, we can infer that Lin's graph has an error because each fragment must equal 35 pages and not 55.

To identify and explain Lin's error, we must take into account how many pages the book has. In this case there are 175 pages, if Andre says that he has read 1/5 of the book we must divide the total number of pages by 5 to find out how many pages Andre has read.

So if Andre has read 1/5, he has read 35 pages and Elena will have read 55 pages. Due to the above, the error in Lin's graph is that each of the segments that divide the total pages into 5 has the wrong value because each one should equal 35 and the fragment that Elena read must take a complete segment and part of another

We must conclude that there are infinitely many primes of the form 3k + 2, where k is a non-negative integer.

To adapt the proof:

We can use a similar contradiction argument.

Suppose that there are only finitely many primes of the form 3k + 2, say p1, p2, ..., pn.

Let N = 3p1p2...pn + 2. Note that N is of the form 3k + 2 for some non-negative integer k.

Now, let's consider the prime factorization of N. Either N is prime and of the form 3k + 2, in which case we have found a new prime of the desired form, contradicting our assumption that there are only finitely many such primes. Or, N is composite and has a prime factorization consisting only of primes of the form 3k + 1 (since any prime of the form 3k + 2 would divide N). But this implies that N itself is of the form 3k + 1.

Now, let's consider the number M = 3N + 2. M is also of the form 3k + 2, and so must have a prime factorization consisting only of primes of the form 3k + 1. But since N is of the form 3k + 1, we have

M = 3(3p1p2...pn + 1) + 2 = 9p1p2...pn + 5. This means that M has a prime factorization consisting of primes of the form 3k + 2, which contradicts our assumption that there are only finitely many such primes.

3oz of ground beef contains 17.8125g of fat (rounded to 2 decimal places).

Along with carbs and protein, fat is one of the three major macronutrients included in the human diet. It is a necessary nutrient that gives off energy, aids in vitamin absorption, and contributes to the formation of hormones and cell membranes. The flavor, texture, and satiety of numerous foods are all influenced by fat in the context of eating. It may be found in a variety of foods, including nuts, seeds, dairy products, meat, and oils.

We can use proportional reasoning to find out how much fat is in 3oz of

ground beef if we know that 16oz of ground beef contains 95g of fat.

The ratio of fat to beef is constant, so we can set up a proportion:

fat in 16oz / 16oz = fat in 3oz / 3oz

We can simplify the left side of the equation by dividing both sides by 16:

fat in 16oz / 16oz = fat in 1oz

So the proportion becomes:

fat in 1oz = fat in 3oz x (3oz/16oz)

We can now substitute the values we know:

fat in 1oz = 95g / 16 x (3oz/16oz)

Simplifying this expression, we get:

fat in 1oz = 5.9375g

Therefore, 3oz of ground beef contains 3 x 5.9375 = 17.8125g of fat (rounded to 2 decimal places).

Y has the same distribution function as the original distribution function F.

Let Y = F^(-1)(U), where U is uniformly distributed on (0,1) and F^(-1) is the inverse function of F.

We want to find the distribution function of Y.

Let y be any real number. Then we have:

F_Y(y) = P(Y ≤ y)

= P(F^(-1)(U) ≤ y)

Since F is a continuous distribution function, it is also an increasing function. Therefore, the inverse function F^(-1) is also an increasing function.

Thus, we can apply the inverse function F^(-1) to both sides of the inequality F^(-1)(U) ≤ y without changing the direction of the inequality:

P(U ≤ F(y)) = F(y)

Therefore,

F_Y(y) = P(F^(-1)(U) ≤ y)

= P(U ≤ F(y))

Answer:

To make a profit in the first year of business, the company needs to sell enough small and large cheese pizzas with their respective boxes to generate more revenue than the cost of making and packaging the pizzas.

Similarly, to make a profit in the second year, the company needs to sell enough small and large cheese pizzas with their respective boxes to generate more revenue than the cost of making and packaging the pizzas. Different combinations of pizzas and boxes can be used to achieve a profit, as long as the total revenue generated is greater than the total cost incurred.

Step-by-step explanation:

To find the profit for each combination of boxes and pizzas, we need to subtract the total cost from the total revenue. Let's call the number of small cheese pizzas sold S, the number of large cheese pizzas sold L, the number of small boxes used for the small pizzas B1, and the number of large boxes used for the large pizzas B2. Then, the profit for each year can be calculated as follows:

First year profit:

Total revenue = 9S + 14.25L

Total cost = 2.5S + 0.25B1 + 4.15L + 0.5B2

Profit = Total revenue - Total cost

Profit = 9S + 14.25L - 2.5S - 0.25B1 - 4.15L - 0.5B2

Profit = 6.5S + 10.1L - 0.25B1 - 0.5B2

Second year profit:

Total revenue = 9S + 14.25L

Total cost = 2.5S + 0.25B1 + 4.15L + 0.5B2

Profit = Total revenue - Total cost

Profit = 9S + 14.25L - 2.5S - 0.25B1 - 4.15L - 0.5B2

Profit = 6.5S + 10.1L - 0.25B1 - 0.5B2

To have a profit for the first year, the profit equation should be greater than 0. We can find different combinations of S, L, B1, and B2 that will satisfy this condition. Here are a few examples:

Sell 10 small cheese pizzas and 5 large cheese pizzas. Use 20 small boxes and 10 large boxes.

Profit = 6.5(10) + 10.1(5) - 0.25(20) - 0.5(10) = $55.75

Sell 20 small cheese pizzas and 10 large cheese pizzas. Use 40 small boxes and 20 large boxes.

Profit = 6.5(20) + 10.1(10) - 0.25(40) - 0.5(20) = $111.50

Sell 30 small cheese pizzas and 15 large cheese pizzas. Use 60 small boxes and 30 large boxes.

Profit = 6.5(30) + 10.1(15) - 0.25(60) - 0.5(30) = $167.25

Similarly, to have a profit for the second year, the profit equation should be greater than 0. We can find different combinations of S, L, B1, and B2 that will satisfy this condition. Here are a few examples:

Sell 15 small cheese pizzas and 7 large cheese pizzas. Use 30 small boxes and 15 large boxes.

Profit = 6.5(15) + 10.1(7) - 0.25(30) - 0.5(15) = $89.65

Sell 25 small cheese pizzas and 12 large cheese pizzas. Use 50 small boxes and 24 large boxes.

Profit = 6.5(25) + 10.1(12) - 0.25(50) - 0.5(24) = $166.65

Sell 35 small cheese pizzas and 17 large cheese pizzas. Use 70 small boxes and 34 large boxes.

Profit
