Answer:
144ft^3
Step-by-step explanation:
To start, we have your formula: [tex]V=\frac{1}{2} (bh) (l)[/tex]
b = base length of the triangle.
h = height of the triangle.
l = length of the prism
Fill in for each of those values:
[tex]V = \frac{1}{2} (6x6)(8)[/tex]
[tex]V=\frac{1}{2} (36)(8)[/tex]
[tex]V=(18)(8)[/tex]
[tex]V=144[/tex]
Your answer, because it is a 3D shape, should be cubed, so:

Express each of the following as a function or 15°:
1. sin195°
2. cos75°
3. tan345°
4. sin105°
5. sin225°
You can express sin195° as -sin15° by using the trig identities.
Here is how to simplify trigWe will be applying trig identities to solve this question
sin195°:
Recall that:
sin(x + 180°) = -sin(x)
then:
sin(195°) = sin(15° + 180°) = -sin(15°)
Therefore,
sin(195°) = -sin(15°).
cos75°:
Recall that:
cos(x) = sin(90° - x)
then:
cos(75°) = sin(90° - 75°) = sin(15°)
Therefore,
cos(75°) = sin(15°)
tan345°:
Recall that:
tan(x + 180°) = tan(x)
then:
tan(345°) = tan(15° + 330°) = tan(15°)
Therefore,
tan(345°) = tan(15°)
sin105°:
Recall that:
sin(x + 90°) = cos(x)
then:
sin(105°) = cos(15°)
Therefore,
sin(105°) = cos(15°).
sin225°:
Recall that:
sin(x + 180°) = -sin(x)
then:
sin(225°) = sin(45° + 180°) = -sin(45°)
Therefore,
sin(195°) = -sin(15°).

Applying the Solution to a 3X3 System
At a family reunion, there only blood relatives, consisting of children, parents, and grandparents, in attendance. There were 400 people total. There were twice as many parents as grandparents, and 50 more children than parents. How many children, parents, and Grandparents were in attendance?
Show up all steps please
Solving the system of equations, the number of children, parents, and Grandparents who were in attendance are 190, 140 and 70 respectively.
Let C, P and G denotes the number of children, parents and the grandparents in the function.
We get the system of equations,
C + P + G = 400 [equation 1]
P = 2G ⇒ G = P/2 [equation 2]
C = P + 50 [equation 3]
Substituting 2 and 3 in 1,
(P + 50) + P + (P/2) = 400
2P + P/2 = 350
5/2 P = 350
P = 140
C = P + 50 = 140 + 50 = 190
G = P/2 = 140/2 = 70
Hence the number of parents = 140, grandparents = 70 and children = 190.

On January 1, a company issued a $500,000, 10%, 8-year bond payable, and received proceeds of $487,000. Interest is payable each June 30 and December 31. The total interest expense on the bond over its eight-year life is $400,000. True or False?
Show working
True. The total interest expense on the bond over its eight-year life is $400,000.
What is the total interest?The total interest expense on the bond is calculated as follows;
Annual interest payment = face value of bond x annual interest rate
= $500,000 x 10%
= $50,000
Semi-annual interest payment = Annual interest payment / 2
= $50,000 / 2
= $25,000
The total interest expense over the bond's life is then calculated as:
Total interest expense = Semi-annual interest payment x Number of semi-annual periods
= $25,000 x 16
= $400,000

Both are interested in expanding the size of their store and parking lot to accommodate potential growth in their customer base. Two possible actions for both the firms are: ‘increase the size of the store and parking lot’ and ‘do not increase the size of the store and parking lot’. Payoffs are defined in terms of increase in annual profits in $million. The following table describes the payoffs for both the firms to alternative actions taken by each of them.

b) [What will be the annual profit growth for each store, if they both follow their dominant strategy? Define Nash Equilibrium and identify the Nash Equilibrium in the table above. (4 marks)]
c) [Suppose the owners of Super Home and Great Home meet for a friendly game of golf one afternoon and happen to discuss a strategy to optimize profit. What should the joint strategy be they should both agree to? What will annual profit growth be for each store under this agreement? (2 marks)]
a) For Super Home, the superior (or dominant) tactic is to magnify the size of the store and parking lot. This is, regardless of what Great Home does, Super Home's payoff is amplified when it expands its size ($1m vs $0.4m if Great Home amplifies; $3.2m vs $2m if Great Home passes).
What is the best strategy for Great Home?Similarly, for Great Home, the logical (or dominant) strategy is also to expand the size of the store and parking lot. This is because, although unrelated to Super Home's decision, Great Home's payoff is augmented when it enlarges its size ($1.5m vs $0.6m if Super Home magnifies; $3.4m vs $2.5m if Super Home disallows).
b) If both stores implement their authoritative plan, Great Home will witness an annual profit growth of $1.5 million, and Super Home will observe an annual profit growth of $1 million.
A Nash Equilibrium comprehends a state wherein each player chooses their finest ploy given the stratagems selected by the other participant(s), and no player can modify their consequence through exclusively adapting their strategy. In this case, the Nash Equilibrium exists in (Increase, Increase), which spans over the payoffs ($1.5m, $1m).
c) The conjunctive approach both stores should commit to would be for Great Home to amplify the size of its store and parking lot, and Super Home to renounce increasing its size.
Under this harmonized approval, the annual profit growth for Great Home will come out at $3.4 million, and for Super Home, it will arrive at $0.4 million. This system gives rise to a higher collective gain compared to the Nash Equilibrium.

How to add vectors by using the head to tail method?In Geometry, a vector is typically composed of two end points. First, is the starting point which is commonly known as a "tail" and the second (ending) point that is commonly known as a "head."
Additionally, the head to tail method of adding two vectors requires drawing the first vector ([tex]\vec a[/tex]) on a graph and then placing the tail of the second vector ([tex]\vec b[/tex]) at the head of the first vector. Finally, the resultant vector would be drawn from the tail of the first vector ([tex]\vec a[/tex]) to the head of the second vector ([tex]\vec b[/tex]).
Next, we would add the two (2) vectors algebraically as follows;
[tex]\vec a + \vec b[/tex] = (4, -3) + (-1, -2)
[tex]\vec a + \vec b[/tex] = [(4 + (-1)), (-3 + (-2))]

Given data ,
Let's use "W" for the number of victories and "T" for the number of ties. The information available indicates that Team Olympus played 19 games and earned a total of 28 points.
Team Olympus receives three points for each victory, so three victories would result in a total of nine points.
Team Olympus receives one point for each tie, making the sum of the tie-related points (T) equal to one times the number of ties.
We may construct the following equation using the information provided:
3W + 1T = 28 be equation (1)
Now , Since Team Olympus played 19 games in total, the total number of games (W + T) should be equal to 19.
W + T = 19 be equation (2)
Subtracting equation (2) from equation (1) , we get
2W = 9
Divide by 2 on both sides , we get
W = 4.5 wins
And , the supplied possibilities (3, 4, 2, 5, 0) do not add up to a total of 28 points, hence none of them are acceptable answers for Team Olympus.

Trigonometry. Can someone help? (Do as many as you can please)
Answer:
1) Let x be the distance from Alberto to the base of the building. Using trigonometry, we have:
tan(70) = 40 / (x + 6)
x + 6 = 40 / tan(70)
x = 40 / tan(70) - 6
x ≈ 11.1 feet
Therefore, Alberto is about 11.1 feet away from the base of the building.
2) Let h be the height of the building. Using trigonometry, we have:
tan(θ) = h / (100 + 1.55)
h = (100 + 1.55) tan(23)
h ≈ 42.9 feet
Therefore, the height of the building is about 42.9 feet.
3) Let θ be the angle of elevation for each ramp. Using trigonometry, we have:
sin(θ) = 22 / 122
θ = sin⁻¹(22/122)
θ ≈ 10.3 degrees
Therefore, the measure of the angle of elevation for each ramp is about 10.3 degrees.
4) Let d be the distance from the boat to the base of the lighthouse. Using trigonometry, we have:
tan(28) = 40 / d
d = 40 / tan(28)
d ≈ 78.5 feet
Therefore, the distance from the base of the lighthouse to the boat is about 78.5 feet.
5) Let x be the distance from General Han Xin's position to the palace. Using trigonometry, we have:
tan(35) = x / 800
x = 800 tan(35)
x ≈ 595.4 meters
Therefore, the palace is about 595.4 meters away from General Han Xin's position.
6) Let h be the height of the clouds. Using trigonometry, we have:
tan(80) = h / 165
h = 165 tan(80)
h ≈ 702.4 meters
Therefore, the clouds are about 702.4 meters high.

8.) The inequality that describes the possible number of calories X, you can eat during the rest of the day would be < 1200. That is option A.
9.) The value of X would be = 3.
How to determine the quantity of calories you will eat for the day?For question 8.)
The quantity of calories for each day < 2200. That is;
1 day < 2200
The calories consumed for breakfast = 350
The calories consumed for lunch = 650
The total calories consumed = 350+650 = 1000 calories.
The amount of calories needed to be consumed the more = 2200-1000 = 1200
Therefore the quantity of calories needed more < 1200 calories.
For question 9.)
t(X) = 3x - 5
where;
t(X) = 4
That is;
4 = 3x - 5
3x=4+5
3x = 9
X = 9/3 = 3
