A soccer coach filled a water cooler with 34.07 liters of water before a game. The players drank 29.6 liters during their game. How many liters of water were left in the cooler?

Answers

Answer:

4.47 liters

Step-by-step explanation:

To find how many liters were left, subtract the amount they drank from the original amount:

34.07 - 29.6

= 4.47

So, there were 4.47 liters of water left in the cooler.

After players drank 29.6 liters of water from 34.07 liters there is 4.47 liters of water left in the cooler.

What are some alternative names for arithmetic operations?

Addition is also known as the sum, subtraction is also known as the difference, multiplication is also known as the product, and division is also known as the factor.

Given, A soccer coach filled a water cooler with 34.07 liters of water before a game.

The players drank 29.6 liters during their game.

∴ Liters of water that is left in the cooler is the difference between water-filled before the game to the water drank by players during their game which is,

= (34.07 - 29.6).

= 4.47 liters are left in the cooler.

find the domain of the graphed function -4-4 x is all real numbers

Answers

Domain and range:

The domain of a function is all the values the the input assumes.

The range of a function is given by all the values that the output assumes.

In a graphic:

The domain is given by the x-values, the horizontal axis.

The range is given by the y-values, the vertical axis.

In this question:

x, in the horizontal axis, assumes values between -4 and 2.

The closed circle at x = -4 and x = 2 indicates that these values are part of the interval.

Thus, the domain of the graphed function is: [tex]-4 \leq x \leq 2[/tex], and the correct answer is given by option D.

For more about domain and range of functions, you can check: https://brainly.com/question/21853810?referrer=searchResults

D. [tex]-4 \le x \le 2[/tex]

The procedure of solution consist consist in determine graphically the Domain of the Function shown in the figure. In this case, the Domain is the Set of values of [tex]x[/tex] in Interval notation, which represented in the "horizontal" axis of the Cartesian Plane. Please notice that black points means that given Function includes extreme values.

By visual examination of the function, we conclude that domain of the function is represented by:

[tex]Dom\{f(x)\} = [-4, 2][/tex]

Which is equivalent to the following expression in Inequality notation:

[tex]-4 \le x \le 2[/tex]

Therefore, we conclude that right answer is D.

(18 , - 10)

Step-by-step explanation:

5x + 4y = 50 .... (1)

x + 2y = - 2 ... (2)

Solve (2) for "x"

x = - 2y - 2 .... (3)

(3) ----> (1)

5(- 2y - 2) + 4y = 50 ⇔ - 6y - 10 = 50 ⇒ y = - 10 .... (4)

(4) ----> (2)

x + 2(- 10) = - 2 ⇒ x = 18

(18, - 10)

Which of the following functions best describes this graph?

O A. y = (x+5)(x-4)
O B. y - (x - 3)(x-6)
O c. y = x2 +9x+18
O D. y = x2 - 2x + 4

Answers

Answer:

c. y=x2+9x+18

Step-by-step explanation:

If we factor y=x2+9x+18 using the x method, the factors 3 and 6 mutliply to 18 as well as add to 9. that means y=x2+9x+18=(x+3)(x+6). From the graph, we can see that when y=0, it is at the x's -3 and -6. If we set (x+3)and(x+6) equal to zero (for ex. x+3=0), our x's are -3 and -6 which are the same zeros as the graph

The quadratic function that best describe the graph is y =  x² + 9x + 18.

Solution of the graph

The solution of the given graph is determined from the intersection of the curve on the horizontal axis.

The two points of intersection of the curve are -6 and - 3.

Quadratic function

The quadratic function is determined from the solutions of the curve.

x = -6 or x = -3

x + 6 = 0 or x + 3 = 0

(x + 6)(x + 3) = 0

expand the bracket as follows;

x² + 3x + 6x + 18 = 0

x² + 9x + 18 = 0

y = x² + 9x + 18

Thus, the quadratic function that best describe the graph is y =  x² + 9x + 18.
