skelet666 [1.2K]

Based on the fact the game of hearts, four players are each dealt 13 cards from a deck of 52

  • The domain is the deck of 52 cards
  • codomain is 4 players
  • function, f(k) maps a card to each player
  • It is surjective

This is further explained below.

<h3>What is a surjective Function?</h3>

A surjective function is a kind of function that exists in mathematics that ensures that any element y may be transferred to element x in such a way that f(x) equals y.

To put it another way, each element that makes up the function's codomain is the mirror image of at least one element that makes up the domain.

Generally, function, f(k) maps a card to each player

And since each player is dealt 13 cards st 13 of the cards are mapped to each player.

It is a function as one card is mapped to one and only one player.

The function is not injective because 13 cards 1 are mapped to one player so it is a many-one function but the injective function does not map two elements to a common clement.

In conclusion, It is surjective as each player is dealt 13 cards. the function is not injective hence rot bijective.

Six times the sum of a number and negative four is twelve. Find the number. Round your answer to the nearest integer, if necessa
GuDViN [60]
If we call the number x, we can write an equation to solve:

6(x - 4) = 12
6 × x = 6x
6 × -4 = -24

So you get 6x - 24 = 12

6x - 24 = 12
+ 24
6x = 12
÷ 6
x = 2

And your final answer is 2, I hope this helps!

Suppose the cost of publishing x books is C(x) = 10000 + 25<img src="https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D" id="TexFormula1" ti
dusya [7]

Answer:

\frac{dC}{dQ} \approx 1.25, C(101)-C(100) = 1.247, \delta = 0.24\,\%

Step-by-step explanation:

The marginal cost function is:

\frac{dC}{dQ} = 12.5\cdot x^{-\frac{1}{2} }

The marginal cost for 100 books is:

\frac{dC}{dQ} \approx 1.25

The difference is:

C(101)-C(100) = 25\cdot (101^{\frac{1}{2} }-100^{\frac{1}{2} })

C(101)-C(100) = 1.247

The relative error is:

\delta = \frac{|1.25-1.247|}{1.25}\times 100\,\%

\delta = 0.24\,\%
