Step-by-step explanation:

How can you determine if the relationship is a direct variation or an inverse variation?

Direct Variation: Because k is positive, y increases as x increases. So as x increases by 1, y increases by 1.5. Inverse Variation: Because k is positive, y decreases as x increases.

Answer:

[tex]\frac{5}{8}[/tex]

Step-by-step explanation:

[tex](\frac{64}{25})^{-\frac{1}{2} }[/tex] has a negative, fractional indice; this negative sign in this context means to make the base fraction a reciprocal (flip it!):

[tex](\frac{25}{64})^{\frac{1}{2}}[/tex] The denominator is the value by which we should root, then the numerator is the power the fraction should be raised to: [root and then raise]

[tex]\frac{(\sqrt{25})^{1} }{(\sqrt{64})^{1} }[/tex] This fraction then becomes:

[tex]\frac{5}{8}[/tex]

We want to see which of the given statements is true for the identical containers with nitrogen gas.

The correct statement is:

"The rate at which nitrogen gas (N2) molecules collide with the container walls is lower in container #1 than in container #2"

Remember the ideal gas equation:

P*V = n*R*T

Where P is the pressure, V is the volume, n is the number of moles, R is a constant, and T is the temperature.

Both gases are in identical containers, so both have the same volume. Also both containers have 1.5 moles of nitrogen, so n is the same number for both containers, and R is a constant, so it is the same for both.

The thing that is different is the temperature, for container 1 we have a temperature of 250K, while for container 2 we have a temperature of 350K, then we can write two pressure equations:

[tex]P_1 = \frac{n*R}{V}*(250k)\\\\P_2 = \frac{n*R}{V}*(350k)[/tex]

Where n*R/V is a constant term.

Then is really clear to see that the pressure exerted by nitrogen will be larger in container 2, because it increases linearly with the temperature and the temperature is larger in container 2.

Also remember that increases in temperature manifest as an increase in the kinetic energy of the molecules of the gas, thus, the container with a larger temperature will have molecules with larger kinetic energy (thus, larger mean velocity)

From the given statements, the only one that is true is:

"The rate at which nitrogen gas (N2) molecules collide with the container walls is lower in container #1 than in container #2"

This collision with the walls is a representation of pressure, this says that container 1 has less pressure than container 2, which is true.

Justice needs $72 to fence in his garden.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Justice needs 24 feet of fencing to surround his garden.

The fencing is priced at $0.25 per inch.

Since, 1 foot = 12 inch

Hence, 24 feet = 24 x 12 inch = 288 inch.

Cost of the fencing in one inch = $0.25

So, Cost of the fencing in 288 inch = 288 x 0.25

                                                      = $72

Thus, Justice needs $72 to fence in his garden.

Subtract 12 from both sides to isolate 4k:

Step-by-step explanation:

x = 1 - i sqrt(2) ^ y = 10 + i sqrt(2)

x = 1 + i sqrt(2) ^ y = 10 - i sqrt(2)

Answer:

Step-by-step explanation:

y = 11 - x  ----------(I)

y  = 2x² - 4x + 6 -----------(II)

Substitute y = 11- x in (II)

11 - x = 2x² - 4x + 6

0 = 2x² - 4x + x + 6 - 11

0 = 2x² - 3x - 5

2x² - 3x  - 5 = 0

Sum = -3

Product = -10

Factors = -5 , 2

2x² - 5x + 2x - 5 = 0

x(2x - 5) + (2x - 5) = 0

(2x -5 )(x +1)=0

2x - 5 = 0  ; x + 1 = 0

2x = 5      ; x = -1

  x = 5/2

When x = -1   ;  y = 11 - (-1) = 11 + 1 = 12

[tex]When x = \dfrac{5}{2} ; y = 11- \dfrac{5}{2}= \dfrac{22}{2}- \dfrac{5}{2}= \dfrac{17}{2}[/tex]

Solution:  (-1 , 12)  and (5/2 , 17/2)

The formula for the number of bacteria in the colony after t minutes is [tex]y=2000000(1.035)^t[/tex]

An exponential growth is in the form:

y = abˣ

where y, x are variables, a is the initial value of y and b > 1

Let y represent the bacteria population after t minutes

Given that initially has 2 million bacteria, hence:

a = 2 million = 2000000

It increases at a rate of 3.5% every minute, hence:

b = 100% + 3.5% = 1.035

The equation is:

[tex]y=2000000(1.035)^t[/tex]

Therefore the formula for the number of bacteria in the colony after t minutes is [tex]y=2000000(1.035)^t[/tex]
