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

<h3>What is a gas?</h3>

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

<h3>What is solubility?</h3>

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

<h3>Which of the following compounds is a gas?</h3>

Note that the solubility of a substance depends on the temperature

For gases, the solubility decreses with incresing temperature
For liquids, temperature has no effect on solubility and
For solids, the solubility increases with temperature if the reaction is endothermixc and dedreases with temperature if the reaction is exothermic.

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

F(x) = x^2. What is g(x)?

marshall27 [118]

Answer:

g(x) = -x^2 - 4

Step-by-step explanation:

f(x) = x^2

To flip the graph, you need the negative of the right side,

y = -x^2

This is a parabola that opens downward, but the vertex is at (0, 0).

Now you need to translate the graph 4 units down, so subtract 4 from -x^2.

g(x) = -x^2 - 4

Evaluate (6x+3y)-z^(2)÷(2x) when x=-3,y=4,z=-6

irina1246 [14]

<h2>Answer:</h2>

<u>24.</u>

<h2>Step-by-step explanation:</h2>

<h3>1. Write the expression.</h3>

$(6x+3y)-\frac{z^{2}}{(2x)}$

<h3>2. Substitute the variables by the respective given value using <u>parenthesis</u>.</h3>

$(6(3)+3(4))-\frac{(6)^{2}}{(2(3))}$

<h3>3. Simplify the expression by applying the hierarchy or mathematical operations.</h3>

<em>a) Solve parenthesis.</em>

$(18+12)-\frac{(6)^{2}}{6}\\ \\30-\frac{(6)^{2}}{6}$

<em>b) Solve the exponent.</em>

$30-\frac{36}{6}$

<em>c) Divide.</em>

$30-6$

<em>d) Subtract.</em>

$24.$

A new car is purchased for 15500 dollars. The value of the car depreciates at 7.5% per year. What will the value of the car be,

mixer [17]

Answer:

$\$9,709.17$

Step-by-step explanation:

we know that

The formula to calculate the depreciated value is equal to

$V=P(1-r)^{x}$

where

V is the depreciated value

P is the original value

r is the rate of depreciation in decimal

x is Number of Time Periods

in this problem we have

$P=\$15,500\\r=7.5\%=0.075\\x=6\ years$

substitute

$V=\$15,500(1-0.075)^{6}=\$9,709.17$
