Answer:

I think your answer is 5 - 9 = -1(9 - 5)

Step-by-step explanation:

Point slope form is the image attatched.

Plugging into the equation and solving:

y2 - y1 = m(x2 - x1)

        \/

5 - 9 = m(9 - 5)

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:

Step-by-step explanation:

To find an angle and it's supplementary angle.

The supplementary angle be = x

So, the angle given is = x - 4.6

When two angles added gives 180°, then those angles are called supplementary angles.

By the problem,

=> x + (x - 4.6) = 180

=> 2x - 4.6 = 180

=> 2x = 180 + 4.6 = 184.6

[tex] = > \frac{2x}{2} = \frac{184.6}{2} [/tex]

=> x = 92.3

So, the supplementary angle is = 92.3° (Ans)(ii)

And, it's required angle is = 180° - 92.3° = 87.7° (Ans)(i)

Supplementary Angles :

Answer:

The slope is -1/3

Step-by-step explanation:

y = -1/3x + 1/4

This equation is written in slope intercept form

y = mx+b  where m is the slope and b is the y intercept

The slope is -1/3 and the y intercept is 1/4

Hello there! :)

y=-1/3x+1/4

-1/3 is the slope

Remember y=mx+b. m is the slope and b is the y-intercept.

Here, m (the slope) is -1/3, and the y-intercept is 1/4

Answer:

Step-by-step explanation:

mean tide is (17.2 + 4.6)/ 2 = 10.9 ft

Amplitude of tide is (17.2 - 4.6)/ 2 = 6.3 ft

The full tide cycle is 2(5.8) = 11.6 hrs

As we are not told the tide condition at 12:00 noon,

I will ASSUME that the tide is high and use the cosine function

D = 10.9 + 6.3cos(2π(t/11.6)) ft

where t is in hours after noon high tide.

make sure your calculator is set to radians.

If you want to use degrees, the equation becomes

D = 10.9 + 6.3cos(360(t/11.6)) ft

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]

Answer:

1$/2.5lb

Step-by-step explanation:

This is a fraction equal to 5 pounds / 2 dollars

We want a unit rate where 1 is in the denominator, so we have to divide the top and bottom by 2.

5 pounds / 2

2 dollars / 2

This should progress to

2.5 pounds/a dollar

This means that the unit rate is 2.5 pounds per dollar.

Answer:

2 liters of 70%

4 liters of 40%

Step-by-step explanation:

Let

x = liters of 70%

Then the remaining amount is

6 - x = liters of 40%

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

Mixing

(70% of x) + (40% of 6 -x) (to get)  50% of 6)

    70(x)    +      40(6-x)         =           50(6)

Simplify

70x + (240 - 40x) = 300

Combine like terms

30x = 60

Divde both sides by 30

x = 2 liters of 70%

6 - x = 4 liters of 40%

The solution is, New line slope will be -2 and, coordinates  (-4. 2).

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

here, we have,

Dilation of a line about a point not on the line shifts the line but leaves the slope intact .

New line slope will be -2

As both A and C lie on a horizontal line y = 2, C' will also lie on the same line

The distance between A and C is 0 - 2 = -2

a scale factor of 3 means C' is -2(3) = -6 units left of A

C' = (2 - 6, 2)

   = (-4. 2)

Hence, The solution is, New line slope will be -2 and, coordinates  (-4. 2).

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.
