Answer:

(4)

Step-by-step explanation:

Integers are:  ... -3, -2, -1, 0, 1, 2, 3 ....

Positive integers are the positive ones of the line above.

Rational numbers include all the numbers between the whole ones, so fractions and decimals included. Any number that can be written as a fraction (including repeating decimals).

Now, domain is the set of x-values (input) of the function.

The input of the function C(w), is w, which is the number of pounds.

You can buy 3 pounds, 4 pounds etc. as well as 3.2 pounds, 3/4 pound etc.

So, you can buy rational numbers number of pounds, not only integers.

Also, NOT ALL RATIONALS, since you can't buy NEGATIVE POUNDS of beef, so we can say:

THe domain is positive rational numbers.

Sholpan [36]

Answer:

<em>Hi There!</em>

Answer:

The hot coca mad by Eli is more chocolaty because it has more chocolate in lesser amount of water.

Because, Arjun takes quantity of chocolate = 20 mL

<em><u>Choice 1.</u></em>

Arjun takes quantity of water = 33 ounces

The Chocolate to Water ratio is

Chocolate : Water = 20 : 33

Dividing by 20, We get

Chocolate : Water = 1 : 1.65

<u><em>Choice 2.</em></u>

Arjun add 1 ml of chocolate in 1.65 ounces of water.

Eli takes quantity of chocolate = 45 mL

Eli takes quantity of water = 66 ounces

The Chocolate to Water ratio is

Chocolate : Water = 45 : 66

Dividing by 45 , we get

Chocolate : Water = 1 : 1.47

Eli add 1 ml of chocolate in 1.47 ounces of water.

So, The hot coca mad by Eli is more chocolaty because it has more chocolate in lesser amount of water.

<em>Good Luck!</em>

The height of a baseball thrown from the catcher to first base is modeled by the function h(t) = –0.09t2 + 0.72t + 6, where h is
Black_prince [1.1K]

The height of a baseball thrown from the catcher to first base is modeled by the function h(t) = -0.09t^2 + 0.72t + 6, where h is the height of the ball measured in feet and t is the time since being thrown, measured in seconds

To find out height of the ball at 10 seconds, we plug in 10 for t

h(t) = -0.09t^2 + 0.72t + 6

h(10) = -0.09(10)^2 + 0.72(10) + 6

h(10)=4.2 feet

the height of the ball at 10 seconds= 4.2 feet
