What is a cosine rule?

A cosine rule is a trigonometric function that can be used to determine the length of side, or measure of the internal angles of a none right angled triangle.

Cosine rule states that;

[tex]b^{2}[/tex] = [tex]a^{2}[/tex] + [tex]c^{2}[/tex] -2acCos B

To determine the missing values of the triangle in the attached diagram, we have;

[tex]b^{2}[/tex] = [tex]a^{2}[/tex] + [tex]c^{2}[/tex] -2acCos B

  = 4^2 + 7^2 - 2(4*7)Cos35^o

  = 16 + 49 -2(36*0.8192)

  = 65 - 58.9824

  = 6.0176

b = (6.0176)^1/2

  = 2.4531

b = 2.45

From sine rule,

a/ Sin A = b/Sin B = c/ Sin C

a/ Sin A = b/Sin B

4/Sin A = 2.45/ Sin 35

Sin A = 4* Sin 35/ 2.45

        = 0.9365

A = Sin^-1 0.9365

  = 69.47

A = 69.5

So to determine the value of C, we have;

A + B + C = 180^o

69.5 + 35 + C = 180

104.5 + C = 180

C = 180 - 104.5

   = 75.5

C = 75.5^o

The volume of the leaning regular hexagonal prism, can be found to be 351. 89 inch ³.

How to find the volume ?

A right triangle can be constructed in a regular hexagon by linking the midpoint of one side and a vertex to the center. This specially-crafted triangle comprises two legs, one of which is half the size of the primary side (acting as the hypotenuse) while the remaining leg lies parallel to the hexagon's apothem (height).

The height of the prism can be found with cosine to be:

h = slanted height x Cos (angle )

h = 11 x Cos ( 70 degrees )

h = 3. 762 inches

James bought 16 bolts at the hardware store for a total of $6.00/ Some were 3-inch bolts that cost 36 cents each and the others were 4-inch bolts that cost 42 cents each. How many 3-inch did James buy

Answers

Let's use the variable "x" to represent the number of 3-inch bolts that James bought.

We know that he bought a total of 16 bolts, so the number of 4-inch bolts he bought would be 16 - x.

The cost of the 3-inch bolts is 36 cents each, so the total cost of the 3-inch bolts would be 0.36x dollars.

Similarly, the cost of the 4-inch bolts is 42 cents each, so the total cost of the 4-inch bolts would be 0.42(16 - x) dollars.

We know that the total cost of all the bolts was $6.00, so we can set up the following equation:

0.36x + 0.42(16 - x) = 6.00

Simplifying and solving for x, we get:

0.36x + 6.72 - 0.42x = 6.00

-0.06x = -0.72

x = 12

Therefore, James bought 12 of the 3-inch bolts.

Hailey goes to a store an buys an item that costs a dollars. She has a coupon for 35%
off, and then a 8% tax is added to the discounted price. Write an expression in terms
of a that represents the total amount that Hailey paid at the register.

Answers

Hailey goes to a store an buys an item that price of a dollars, so the expression that represents the total amount that Hailey paid at the register in terms of a is 0.702a.

The amount of discount that Hailey receives is 35% of the original price, which is 0.35a. Therefore, the discounted price she pays is a - 0.35a = 0.65a.

The amount of tax that is added to the discounted price is 8% of the discounted price, which is 0.08(0.65a) = 0.052a.

So the total amount that Hailey paid at the register is the discounted price plus the tax:

total amount = discounted price + tax

total amount = 0.65a + 0.052a

Simplifying this expression, we get:

total amount = 0.702a

Therefore, the expression that represents the total amount that Hailey paid at the register in terms of a is 0.702a.

Consider the function [tex]f(x) = \frac{2x}{1-x^2}[/tex]

Consider the limit of function f(x) as x approaches infinity (x → ∞)

[tex]\lim_{n \to \infty} f(x)\\\\= \lim_{n \to \infty} \frac{2x}{1-x^2} \\\\= \lim_{n \to \infty} \frac{2x/x}{(1-x^2)/x}\\\\ = \lim_{n \to \infty} \frac{-2}{x}[/tex]

The term "end behavior" describes the behaviour or trend of a function's graph as its x-values go closer to positive or negative infinity. It explains how the function "ends" or acts when x is extremely large (positive infinity) or extremely small (negative infinity). The degree and leading coefficient of the polynomial formulation of the function can be used to predict the final behaviour. For instance, the left and right ends of the graph will both point upward for a function with an odd-degree polynomial and a positive leading coefficient (towards positive infinity).

For the function f(x) = -2∛x as x approaches negative infinity because the function has a negative coefficient in front of the cube root, which means that as x decreases significantly, the absolute value of the cube root increases. The function also approaches negative infinity as x approaches very big (positive) values and the cube root approaches very small absolute values. As a result, the function's final behaviour is that it approaches negative infinity as x gets closer to both negative and positive infinity.

Arcs may be created from the circumference of a circle. It is referred to as the curved line that connects two locations on a circle's perimeter and splits it into segments. The length of an arc is inversely proportional to the angle it makes at the centre of the circle.

When the central angle rises, so does the arc's length, and vice versa. Arcs are commonly used to depict and compute measurements of circles and circular objects in geometry, trigonometry, and physics.

For given problem,

Answers

Answer:

Step-by-step explanation:

To solve this problem, we need to use the distance formula to find the length of each side of the triangle, and then apply the Pythagorean theorem to determine whether the triangle is a right triangle.

Let's label the three vertices of the triangle as A, B, and C, and their coordinates as follows:

A = (-2, 5)

B = (3, -1)

C = (1, 3)

The length of AB is:

AB = sqrt((3 - (-2))^2 + (-1 - 5)^2) = sqrt(25 + 36) = sqrt(61)

The length of AC is:

AC = sqrt((1 - (-2))^2 + (3 - 5)^2) = sqrt(9 + 4) = sqrt(13)

The length of BC is:

BC = sqrt((1 - 3)^2 + (3 - (-1))^2) = sqrt(4 + 16) = sqrt(20) = 2sqrt(5)

Now, we need to check whether the triangle is a right triangle. We can do this by checking whether the sum of the squares of the two shorter sides (AB and AC) is equal to the square of the longest side (BC). If it is, then the triangle is a right triangle.

AB^2 + AC^2 = 61 + 13 = 74

BC^2 = (2sqrt(5))^2 = 20

Since AB^2 + AC^2 is not equal to BC^2, the triangle is not a right triangle.

Therefore, the answer is: "The triangle is not a right triangle."

The coefficients of the function and their meaning are described as follows:

m is the slope of the function, representing the change in the output variable y when the input variable x is increased by one.b is the y-intercept of the function, which is the initial value of the function, i.e., the numeric value of the function when the input variable x assumes a value of 0. On a graph, it is the value of y when the graph of the function crosses the y-axis.

For this problem, we have that when x increases by one, y decays by two, hence the slope m is given as follows:

m = -2.

Hence:

f(n) = -2n + b.

When n = 1, f(n) = -6, hence the intercept b is obtained as follows:

-6 = -2 + b

b = -4.

What is the equation for making a skateboard?

Here's an equation that outlines my "recipe" for making a skateboard:

Skateboard = Deck + Grip Tape + Trucks + Wheels + Bearings + Hardware + Assembly + Personalization

Explanation of the equation:

Deck: The wooden or composite board that serves as the main body of the skateboard. It is typically made from layers of plywood or other materials, and its dimensions (length, width, concavity, etc.) can be customized based on personal preference.

Grip Tape: A sandpaper-like material that is applied to the top of the deck to provide traction for the rider's feet. It is usually made of adhesive-backed paper or fabric and comes in various designs and colors.

Trucks: Metal T-shaped components that are mounted on the underside of the deck and serve as the axle and suspension system of the skateboard. They consist of a baseplate, hanger, kingpin, bushings, and hardware, and are responsible for allowing the board to turn and pivot.

Wheels: Typically made of urethane or other durable materials, skateboard wheels come in various sizes, shapes, and hardness levels (durometer). They are attached to the trucks and provide smooth rolling and maneuverability.

Bearings: Small, round metal or ceramic components that fit inside the wheels and allow them to spin freely on the axle. They are crucial for reducing friction and enabling the wheels to roll smoothly.

Hardware: Nuts, bolts, and screws used to attach the trucks to the deck and assemble the skateboard. They are typically made of metal and come in different sizes and lengths.

Assembly: The process of putting together all the skateboard components to create a functional skateboard. It involves attaching the trucks to the deck using the hardware, installing the wheels and bearings, and applying the grip tape.

Personalization: This refers to any additional customization or personal touches that a skateboarder may choose to add to their skateboard, such as stickers, artwork, or modifications to the deck shape or truck settings, to make it unique and suited to their individual style.

B.) Angle C is 75 degrees.

C.) Sin(A) is 3√(255)/85 in simplest radical form.

What is trigonometry?

Trigonometry is a branch of mathematics that examines triangle-related relationships and calculations, particularly the measurement of triangle sides and angles.

A.) We can apply the following formula to determine the triangle's area:

Area = (1/2) × b × a × sin(C)

Since we know b=7 and a=6, we have:

Area = (1/2) × 7 × 6 × sin(C)

To find sin(C), we can use the fact that cos(C) = 1/4 and the Pythagorean identity:

sin²(C) + cos²(C) = 1

sin(C) = √(1 - cos²(C)) = √(1 - 1/16) = √(15/16) = √(15)/4

B.) To find C, we can use the Law of Cosines:

c² = a² + b² - 2ab×cos(C)

c² = 6² + 7² - 2(6)(7)(1/4) = 85/2

c = √(85)/2

Now we can use the Law of Cosines again to find angle C:

cos(C) = (a² + b² - c²)/(2ab)

cos(C) = (6² + 7² - (√(85)/2)²)/(267) = 1/4

C.) To find sin(A), we can use the Law of Sines:

sin(A)/a = sin(C)/c

(d) [2 marks] Find the period of the function in part (c), and describe what the period represents.
(e) [2 marks] Find the amplitude of each function, and describe what the amplitude represents.

Answers

(a) The graph is a sine curve with amplitude 20, period 1, and vertical shift 100. At t=0, the blood pressure is 100 mmHg. The graph oscillates between a minimum of 80 mmHg and a maximum of 120 mmHg.

(b) The period is 1 second, which represents the time it takes for one complete cycle of the sine wave. In this case, it represents the time it takes for the blood pressure to go through one complete cycle (from minimum to maximum to minimum again).

(c) The graph is a sine curve with amplitude 20, period 1/2, and vertical shift 100. At t=0, the blood pressure is 100 mmHg. The graph oscillates between a minimum of 80 mmHg and a maximum of 120 mmHg.

(d) The period is 1/2 second, which represents the time it takes for one complete cycle of the sine wave. In this case, it represents the time it takes for the blood pressure to go through one complete cycle (from minimum to maximum to minimum again).

(e) The amplitude of each function is 20, which represents half the difference between the maximum and minimum blood pressure.

suppose you want to double the area of the patio shown at the right. find the increase x of both the length and width of the patio

Answers

The New Area based on the information will be 168ft

How to calculate the area

Expanding the above equation, we get:

120ft² + 22x + x² = 240ft²

Rearranging and simplifying, we get:

x² + 22x - 120 = 0

Since the increase cannot be negative, we take the positive value of x:

x = 2

Therefore, the increase in both the length and width of the patio should be 2ft to double its area.

New Length = 10ft + 2ft = 12ft

New Width = 12ft + 2ft = 14ft

New Area = 12ft x 14ft = 168ft²

Consider the quadratic equation x2 + 9x + 10 = 0. Which of the following is the correct form after substituting a, b, and c into the
Quadratic Formula?

Answers

Given a quadratic in the form ax^2+bx+c=0. We can use the quadratic equation to solve for the values of x. Where the quadratic eqauation is written as (-b±√(b^2-4ac))/2a.

Given the quadratic equation x^2+9+10=0 our coefficients are as follows….
a=1
b=9
c=10

Plugging these into the quadratic formula we get,

(-(9)±√((9)^2-4(1)(10)))/2(1)

Thus, the proper set up is the SECOND OPTION.

What are the implications of your statistical conclusions in terms of driving safety recommendations? reading:The accelerometer keeps track of how quickly the speed of your vehicle is changing. When your car hits another caror wall or telephone pole or deerthe accelerometer triggers the circuit. The circuit then sends an electrical current through the heating element, which is kind of like the ones in your toaster, except it heats up a whole lot quicker. This ignites the charge which prompts a decomposition reaction that fills the deflated nylon airbag (packed in your steering column, dashboard or car door) at about 200 miles per hour. The whole process takes a mere 1/25 of a second. The bag itself has tiny holes that begin releasing the gas as soon as its filled. The goal is for the bag to be deflating by time your head hits it. That way it absorbs the impact, rather than your head bouncing back off the fully inflated airbag and causing you the sort of whiplash that could break your neck. Sometimes a puff of white powder comes out of the bag. Thats cornstarch or talcum powder to keep the bag supple while its in storage. (Just like a rubberband that dries out and cracks with age, airbags can do the same thing.) Most airbags today have silicone coatings, which makes this unnecessary. Advanced airbags are multistage devices capable of adjusting inflation speed and pressure according to the size of the occupant requiring protection. Those determinations are made from information provided by seat-position and occupant-mass sensors. The SDM also knows whether a belt or child restraint is in use.Today, manufacturers want to make sure that whats occurring is in fact an accident and not, say, an impact with a pothole or a curb. Accidental airbag deployments would, after all, attract trial lawyers in wholesale lots. So if you want to know exactly what the deployment algorithm stored in the SDM is, just do what GM has done: Crash thousands of cars and study thousands of accidents. The Detonation: Decomposition Reactions Manufacturers use different chemical stews to fill their airbags. A solid chemical mix is held in what is basically a small tray within the steering column. When the mechanism is triggered, an electric charge heats up a small filament to ignite the chemicals andBLAMMO!a rapid reaction produces a lot of nitrogen gas. Think of it as supersonic Jiffy Pop, with the kernels as the propellant. This type of chemical reaction is called decomposition. A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances. A reaction is also considered to be decomposition even when one or more of the products are still compounds.Equation 1. general form of decomposition equations When sodium azide (NaN3) decomposes, it generates solid sodium and nitrogen gas, making it a great way to inflate something as the small volume of solid turns into a large volume of gas. The decomposition of sodium azide results in sodium metal which is highly reactive and potentially explosive. For this reason, most airbags also contain potassium nitrate and silicon dioxide which react with sodium metal to convert it to harmless compounds. Equation 2. decomposition of sodium azide Ammonium nitrate (NH4NO3), though most commonly used in fertilizers, could also naturally decompose into gas if its heated enough, making it a non-toxic option as an airbag ingredient. Compared to the sodium axide standard, half the amount of solid starting material is required to produce the same three total moles of gas, though that total is comprised of two types, dinitrogen monoxide (N2O) and water vapor (H2O). Equation 3. decomposition of ammonium nitrate Highly explosive compounds like nitroglycerin (C3H5N3O9) are effective in construction, demolition, and mining applications, in part, because the products of decomposition are also environmentally safe and nontoxic. However, they are too shock-sensitive for airbag applications. Even a little bit of friction can cause nitroglycerin to explode, making it difficult to control. The explosive nature of this chemical is attributed to its predictable decomposition which results in nearly five times the number of moles of gas from only four moles of liquid starting material when compared to both sodium azide and ammonium nitrate alternatives.You're are NOT answering this: Scientific question: How does the choice of chemical ingredient ia airbn ag influence their effectiveness.As you talks about the dimensional analysis setup, stock and explain each part using da ts format he article.Point directly to the collected data as evidence.
