Answer:

If you divide 32.4 by 6, then you get 5.4 as an answer

Answer:

  No

Step-by-step explanation:

You want to know if there is enough information to claim ∆PQT ≅ ∆SRT by the HL theorem.

The HL theorem tells you right triangles are congruent if they have one leg (L) and the hypotenuse (H) congruent.

Here, the triangles are not indicated as being right triangles, so the HL theorem cannot be applied.

__

Additional comment

There is not enough information here to permit the triangles to be declared congruent.

For congruence by any theorem, we'd need to know that angle T is the largest angle in each triangle, a condition not supported by the evidence.

Though rarely (if ever) seen in congruence discussions, a claim of SSA congruence can only be supported if the angle (A) is opposite the longest side. When the angle is 90°, this is called the HL congruence theorem. When the angle is known to be obtuse, it will always be opposite the longest side.

When the given angle is opposite the shortest of the two given sides, there are two possible triangles that can be constructed. Hence congruence cannot be guaranteed between two triangles with the same SSA dimensions.

y+3=5(x+4)      Expand R side, then subtract 3 from both sides of equation

y = 5x+ 17     Done .

Answer:

y = 5x+17

Step-by-step explanation:

To get this equation to slope intercept form, get the y variable by itself on one side of the equal sign.

y+3=5(x+4)

[Distribute the 5 to x and 4]

y+3 = 5x+20

[Subtract 3 from both sides]

What is expected mean square ?

Expected mean squares in statistics are the predicted values of certain statistics emerging in sums of squares partitions in the analysis of variance. They can be used to determine which statistic belongs in the denominator of an F-test that is being used to test the null hypothesis that a given effect is not there.

Not often, although in some circumstances, perhaps. The average squared departure of observed data values from the sample or population mean is known as variation. The average squared difference between actual and anticipated values is known as MSE (mean squared error).

Answer:

the volume of the cone is approximately 28.26 cubic inches.

Step-by-step explanation:

To find the volume of a cone, you can use the formula:

V = (1/3) * π * r^2 * h

where V is the volume of the cone, r is the radius of the base of the cone, and h is the height of the cone.

Using the dimensions provided in the diagram, the radius of the base of the cone is 3 inches and the height of the cone is 8 inches. Plugging these values into the formula, we get:

V = (1/3) * π * 3^2 * 8

= (1/3) * 3.14 * 9 * 8

= 28.26 cubic inches

So, the volume of the cone is approximately 28.26 cubic inches.

The graph of the given function, g(x) = -5^x + 5, is shown below

From the question, we are to graph the given function.

From the given information,

The given function is

g(x) = -5^x + 5

To graph the function, we will determine some of the points on the line

When x = -2

g(2) = -5^(-2) + 5

g(2) = -1/25 + 5

g(2) = 4 24/25 = 4.96

When x = -1

g(1) = -5^(-1) + 5

g(1) = -1/5 + 5

g(1) = 4 4/5 = 4.8

When x = 0

g(0) = -5^(0) + 5

g(0) = -1 + 5

g(0) = 4

When x = 1

g(1) = -5^(1) + 5

g(1) = -5 + 5

g(1) = 0

When x = 2

g(2) = -5^(2) + 5

g(2) = -25 + 5

g(2) = -20

Step-by-step explanation:

Answer:

Step-by-step explanation:

In this case, the terminal point of theta/2 can be determined using the following steps:

Since cos(theta/2) < 0 and the cosine function has a range of [-1, 1], it follows that theta/2 must be in the second or third quadrant (90 degrees to 180 degrees or 180 degrees to 270 degrees).

To find the terminal point of theta/2, we can use the formula for converting from polar to Cartesian coordinates: x = rcos(theta) and y = rsin(theta), where (x,y) is the Cartesian coordinates of the terminal point, r is the radius, and theta is the angle in radians.

In this case, the radius is 1 (since the terminal point is on the unit circle) and the angle is theta/2. Substituting these values into the formulas above, we get:

x = 1 * cos(theta/2)

y = 1 * sin(theta/2)

To find the values of cos(theta/2) and sin(theta/2), we can use the identity cos(theta/2) = sqrt((1 + cos(theta))/2) and sin(theta/2) = sqrt((1 - cos(theta))/2).

Substituting the given value of cos(theta) (-1/9) and the identities above into the formulas for x and y, we get:

x = sqrt((1 + (-1/9))/2) = -sqrt(2)/3

y = sqrt((1 - (-1/9))/2) = sqrt(8)/3

Thus, the coordinates of the terminal point of theta/2 are (-sqrt(2)/3, sqrt(8)/3).

The terminal point (a₁, a₂) for theta/2 is (-2/3, √(5) / 3).

To find the terminal point (a₁, a₂) of theta/2, use the half-angle identity for cosine:

cos(theta/2) = ± √((1 + cos(theta)) / 2)

Given that cos(theta) = -1/9 and cos(theta/2) < 0, the negative sign should be used in the half-angle identity.

Calculate cos(theta/2):

cos(theta/2) = - √((1 + cos(theta)) / 2)

cos(theta/2) = - √((1 - 1/9) / 2)

cos(theta/2) = - √((8/9) / 2)

cos(theta/2) = - √(8/18)

cos(theta/2) = - √(4/9)

cos(theta/2) = - 2/3

Cos(theta/2) = -2/3. To find the terminal point (a₁, a₂), determine the values of a₁ and a₂.

Since cos(theta/2) is negative, a₁ is negative. To find the value of a₂, use the Pythagorean identity:

cos²(theta/2) + sin²(theta/2) = 1

Since cos(theta/2) = -2/3, calculate sin(theta/2):

sin²(theta/2) = 1 - cos²(theta/2)

sin²(theta/2) = 1 - (-2/3)²

sin²(theta/2) = 1 - 4/9

sin²(theta/2) = 5/9

sin(theta/2) = ± √(5/9)

sin(theta/2) = ± √(5) / 3

Since theta is in the second quadrant (cos(theta) = -1/9), sin(theta) is positive in the second quadrant. Therefore, sin(theta/2) = √(5) / 3.

Now, sin(theta/2) = √(5) / 3.

So, the terminal point (a₁, a₂) for theta/2 is (-2/3, √(5) / 3).

Approximately, water does it hold two hours later is = 248.72 liters

Given that,

The holding tank contains 1000 liters of water

Water does it hold two hours later,

Then,

1) Integrate the function, from t =0 to t = 120 minutes to obtain the number of liters pumped out in the entire interval, and

2) Substract the result from the initial content of the tank (1000 liters).

So

We can write,

Let us assume,

Integral of (6 - 6 [tex]e^{-0.13t}[/tex] ) dt  ]from t =0 to t = 120 min

= 6t + 6 [tex]e^{-0.13t}[/tex] / 0.13

= 6t + 46.1538 6 [tex]e^{-0.13t}[/tex] ] from t =0 to t = 120 min

= 6*120 + 46.1538 e^(-0.13*120) - 0 - 46.1538

= 720 + 46.1538 (1.678) - 46.1538  

= 720 + 77.44 - 46.1538 liters

= 751.28 liters

2) If the holding tank contains 1000 liters of water,

1000 liters - 751.28 liters = 248.72 liters

Therefore,

Approximately, water does it hold two hours later is = 248.72 liters

The gross profit of the Blog Inc would be $22,370.

Gross profit is the profit of a company or an entity after subtracting all the costs that are related to manufacturing and selling its products or services. Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that  Sales: $50,000

Returns: $4,680

Cost of goods sold: $22,950

Therefore,

Net Sales: 50,000 - 4,680

= 45,320

We can calculate the Gross Profit;

Gross Profit = (Net Sales – Cost of Goods Sold)

                      = ($45,320- $22,950)

                       = $22,370
