Answer:

-64

Step-by-step explanation:

Since this is a piecewise defined function

We need to find where x=- 4 is defined

f(-4) = x^3  -5<=x<=2

      = (-4)^3

     = -64

She is serving hot coffee and cold coffee in two rectangular-shaped tanks, each with dimensions width 8.75 inches, length 8.75 i
Blababa [14]

The volume of the coffee in each tank will be 1760. in³. The mass of cold coffee and hot coffee will be 6163.29 oz and 10213.45 oz. Then the number of the tank placed on a table is one only.

<h3>How to find the density and volume?</h3>

She is serving hot coffee and cold coffee in two rectangular-shaped tanks, each with dimensions width of 8.75 inches, a length of 8.75 inches, and a height of 23 inches.

The hot coffee has a density of 5.8 oz/in³ and the cold coffee has a density of 3.5 oz/ in³.

Then the volume of the coffee in each tank will be

We know that the dimension of both tanks is equal. Then the volume will remains equal.

Volume = L × B × H

Volume = 8.75 × 8.75 × 23

Volume = 1760.9375 ≅ 1760.94 in³

Then  the mass of the coffee in each the tank will be

The mass of hot coffee will be

Mass = Density × Volume

Mass = 5.8 × 1760.94

Mass = 10213.45 oz

The mass of cold coffee will be

Mass = Density × Volume

Mass = 3.5 × 1760.94

Mass = 6163.29 oz

Then the number of the tank placed on a table is one only.

More about the density and volume link is given below.

(H+k)-(j-2k) if h= -3 j= -2 and k= -9
nekit [7.7K]
If you change all the variables to the given valuables, the new equation would be (-3 + -9) - (-2 - 2 x -9)


Solve what's in the parenthesis first. -3 + -9 is -12. -2 x -9 is -18, and -2 - -18 is 16. Then you do -12 - 16 and you get -28

-28 is the answer :D

Answer:

M, B, A, T, K are the points of the statement: x<y

Step-by-step explanation:

oh dis is easy peasy lemony squeezy yes big bran time now onto the question :D

So the X has to be smaller than the Y. right?

ok, let's go with point M first shall we?

Coordinates are: 0, 6

is X smaller than Y? yes. yes indeed it is...

----------------------------------------------------------

Point N:

Coordinates are: 3, 3

Is X smaller than Y? no. No they are not.

------------------------------------------------------------

Then you continue doing this for the rest of the points. Remember: Negatives are a bit tricky! -3 may not be smaller than -6 :)
