in the game of hearts, four players are each dealt 13 cards from a deck of 52. is this a function? if so, what are the domain an
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.

A cup of hot coffee is initially at 70 ° C and is left in a room that has a temperature
fgiga [73]

Answer:

It will take 4 minutes and 30 seconds for hot coffee to cool to a temperature of 25 ° C

Step-by-step explanation:

This problem can be modeled by a first order equation

T(t) = TA + kt

In which TA is the temperature at instant zero and r is the rate of warming(g>0) or cooling(k<0). t is the time in minutes.

The initial temperature of the cup of coffee is 70ºC. So TA = 70. The temperature cools  at the rate of 10ºC per minute, so k = -10. So, the equation of the model is:

T(t) = 70 - 10t

We want to know the instant of time when T = 25, so:

25 = 70 - 10t

10t = 70 - 25

10t = 45

t = 4.5 minutes

It will take 4 minutes and 30 seconds for hot coffee to cool to a temperature of 25 ° C

Please help thanks!!
Nezavi [6.7K]

Answer:

x=1/3

Step-by-step explanation:

first you can simplify the 2 fractions (if possible) (2b-2/4 = b-3/8) in the fraction you can take out a 2 in the top binomial it will look like this 2(x-1)/4 then you can cancel out the 2 and that will leave you with x-1/2 = x-3/8 and  then you will multiply both denominators to the opposite side 8(x-1)=2(x-3) then get rid of the parentheses 8x-8=2x-6 then get the x's to one side by adding and 8 too both sides and subtracting 2x from both sides 8x-2x=-6+8 then combine like terms 6x=2 then divide the 6 you get 2/6 simplify and your final answer will be 1/3.
