Using the graph of solubility, D. Ce₂(SO₄)₃ is a gas

A gas is a state of matter with no fixed shape or volume.

Solubility of a substance is the amount of solute that can dissolve in unit volume of solvent at a given temperature.

Note that the solubility of a substance depends on the temperature

From the graph above, we see that the compound with the least solubility is Ce₂(SO₄)₃. Since the solubility of gases derease with increasing temperature, thus Ce₂(SO₄)₃ is a gas

So, using the graph of solubility, D. Ce₂(SO₄)₃ is a gas

[tex]27x^{12}[/tex] smaller cubes will fit in the larger cube.

Given,

Side length of the smaller cube = [tex]x^{2}[/tex] units.

Side length of the larger cube = [tex]3x^{6}[/tex] units.

We have to find the number of smaller cubes that can be fitted in the larger cube.

Volume of cube is given by the formula,

Volume = (side)³

Volume of the larger cube = [tex](3x^{6} )^{3}[/tex]   =  [tex]27x^{18}[/tex]units³

Volume of the smaller cube = [tex](x^{2} )^{3}[/tex] = [tex]x^{6}[/tex] units³

Let the number of smaller cube that can be fitted in the larger cube = n

Volume of  n cubes = [tex]nx^{6}[/tex] units³

If space inside the larger cube will be occupied by 'n' smaller cubes,

  volume of n smaller cubes = Volume of a larger cube

                                      [tex]nx^{6}[/tex]           =  [tex]27x^{18}[/tex]

                                       n             = [tex]27x^{12}[/tex]

Therefore, [tex]27x^{12}[/tex] smaller cubes can be fitted in the larger cube.

Step-by-step explanation:

The function C(F) to calculate the temperature in degrees Celsius for a given temperature in degrees Fahrenheit will be equal to [tex][(\frac{5}{9}F) -\frac{160}{9}][/tex]

As per the question statement,  the formula [F(C) = 9/5C + 32] is to calculate the temperature in degrees Fahrenheit for a given a temperature in degrees Celsius.

We are required to determine the function to calculate the temperature in degrees Celsius for a given temperature in degrees Fahrenheit.

Since, [F(C) = 9/5C + 32],

[tex]or, [F = \frac{9}{5} C + 32]\\or, (F-32)= \frac{9}{5} C\\or, \frac{9}{5} C=(F-32)\\or,C=\frac{5}{9} (F-32)\\or,C=\frac{5}{9}F-\frac{160}{9}[/tex]

the range of the function g(x) will be y ≤ 0.

We know that the absolute value function g(x) can be written as:

g(x) = a*|x|

Remember that the range of f(x) = |x| is y > 0, and a is a negative number, so the function is reflected over the horizontal axis.

Then the maximum value will be when x = 0, then:

g(0) = a*|0| = 0, that is the maximum.

And then the function opens downwards. Then the range will be y ≤ 0.

So the range of the absolute value function g(x) is the set of all real values equal to or smaller than zero.

A logarithmic and even sometimes log function is the inverse of an exponential function. We could employ a log function to find an exponent.

We should be able to transform between logarithmic as well as exponential forms in order to calculate earthquake magnitudes and otherwise correlate the magnitudes of two distinct earthquakes.

Let's use this information to make our log. Here is the logarithmic function:

Now, as for the represented expression;

No valid conclusion drawn from the statements.

You can "detach" the hypothesis from the conclusion using the law of detachment. More specifically, if p and p -q are known to be true, we can infer that q is true. On the other hand, we can cram conditional statements together using the law of syllogism. When p-q and q-r are known to be true, they can be combined to form p-r. After all, it would be silly-gism to go through q when we can just go from p to r.

P = quadrilateral has diagonals

Q = quadrilateral diagonals bisect each other

R= the quadrilateral is a parallelogram

Statement P is true because all quadrilaterals have 2 diagonals that runs from one edge to another eg square, rectangle, parallelogram, kite etc

Statement Q is False because not all quadrilateral's diagonals bisect each other as in the case of trapezium, likewise quadrilateral whose diagonals bisects each other are not only parallelogram, kite, square and rectangle diagonals bisect each other.

Statement R is False because a quadrilateral whose diagonals bisect each other is not only parallelogram. Square, rectangle and Kite diagonals also bisect each other, and they are also parallelogram.

Therefore, no valid conclusion made from the statements because parallelogram is not the only quadrilateral whose diagonals bisect each other and not all quadrilateral's diagonals bisect each other.

Radical expression containing third root terms will be first multiplied and then simplified to its simplest form.

A radical expression is a mathematical expression containing a radical symbol (√). A radical expression contains three distinct parts:

1. A radical symbol which is the square root sign.

2. A radicand which is a component inside the radical,

3. A degree which is the root represented by the radical.

In the given expression, the radicand is 9 while the degree is 3.

As the degree is the same for both the terms, we can multiply the radicand.

Multiplying the radicand terms,

∛(9*9)=∛81

Simplifying the radicand,

∛(3*3*3*3)

Taking the cube root and simplifying,

The Quatric polynomial is x⁴ + 11x³ + 20x² - 44x - 96

Given,

Zeros are: x = 2, x = -3, x = 8, and x = 2

That is: x + 2 = 0, x - 3 = 0, x + 8 = 0, and x + 2 = 0

So the factors are: (x + 2) (x - 3) (x + 8) (x + 2) = 0

Multiply two at a time:

   (x + 2)(x - 3) = x² - x - 6

   (x + 8)(x + 2) = x² + 10x + 16

Now multiply those polynomials together using distributive method:

x² (x² + 10x + 16)  - x(x² + 10x + 16)  - 6(x² + 10x + 16)

= x⁴ + 10x³ + 16x² + x³ + 10x² + 16x - 6x² - 60x - 96

The temperature of the liquid at 3PM will be -7.5 °C

The initial temperature of the liquid at 9 AM  = 0°C

Given that the temperature changes by -5/4 °C each hour.

That is the rate of change of temperature = -5/4 °C

We have to find the temperature of the liquid at 3 PM.

Let x denote the number of hours.

Then the temperature after x hours, t = 0 + ( -5/4)x = -(5/4)x is the linear equation modelling this set up.

So from 9 AM to 3PM, the number of hours =  6 hours

Put x = 6 .

a) Jeremy get to keep 85%

b) $6.273 is Jeremy's hourly take home wage.

Given,

Jeremy has a job at the movie theatre.

Hourly wage of Jeremy = $7.38

The % of income withheld for taxes and social security = 15%

7.38 × (15/100) = 1.107

That is, $1.107 from Jeremy's income is withheld for taxes and social security.

a) Percentage of income Jeremy get to keep:

= 100% - Withheld percentage

= 100 - 15

= 85

So, Jeremy gets 85% of his income to keep with him.

Answer:

h = -9

Step-by-step explanation:

Open the parentheses:

2(h+3.5) = -11

2h+7 = -11

Subtract 7 both sides

2h = -11 - 7

2h = -18

h = -9

Answer: |81 - (-29)|==> C

Step-by-step explanation:

h=high temperature

h=81

l=low temperature

l=-29

d=difference in high and low temperature

h-l=d

81-(-29)=d

81+29=d

d=110 ==> |81 - (-29)|=|81 +29|=|110|=110

|81 - (-29)|==> C

|81 -29|=|52|=52

-29 + 81=81-29=52
