Trig, how to use trigonometric ratios to find sides and angles to triangles
Answers
Solution
Trigonometric ratios are the ratios of the length of sides of a triangle. These ratios in trigonometry relate the ratio of sides of a right triangle to the respective angle. The basic trigonometric ratios are sin, cos, and tan, namely sine, cosine, and tangent ratios. The other important trig ratios, cosec, sec, and cot, can be derived using the sin, cos, and tan respectively.

Answers
In triangle ABC, sin A is therefore about equal to 0.9009.
How is the C in the triangle ABC solved?Pythagoras' theorem asserts that: a2 + b2 = c2 in a right triangle with cathects a and b and with hypotenuse c. Take the square root of both sides to find the answer to the equation for c: c = (b2+a2). This Pythagorean theorem extension can be thought of as a "hypotenuse formula".
We may use the Pythagorean theorem to determine the length of side a because angle C is a right angle:
a² + b² = c²
7² + 17² = (13√2)²
49 + 289 = 338
Therefore, a = √338.
We can use the sine ratio to determine sin A:
opposite/hypotenuse = b/c for sin A
sin A = 17/(13√2)
With the aid of a calculator, we can determine that this is roughly 0.9009.
Sin A = 0.9009, rounded to the nearest ten thousandth.
Hence, sin A has a value of around 0.9009.

A salesperson gets a 5% commission on each pair of shoes they sell. This week, they sold $300 worth of shoes. How much commission will they receive
Answers
According to the solution we have come to find that, the salesperson will receive a commission of $15 for the week.
What is probability?Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, where 0 means that the event is impossible and 1 means that the event is certain.
Probability can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes. For example, if you roll a standard six-sided die, there are six possible outcomes, each with an equal chance of occurring. The probability of rolling a 3 is 1/6, because there is only one favorable outcome (rolling a 3) out of six possible outcomes.
If the salesperson gets a 5% commission on each pair of shoes they sell, we can calculate their commission by multiplying the total sales by 0.05 (which is 5% expressed as a decimal):
Commission = Total sales * 0.05
In this case, the total sales are $300, so we can plug that into the formula:
Commission = $300 * 0.05
Commission = $15
Therefore, the salesperson will receive a commission of $15 for the week.

C. It is required by law in any state in America.
D. It is very expensive and hard to finance.

Answers
Explanation:
Most states (but not all) require liability insurance at minimum. This covers injury and property damage to the person you accidently hit. It likely does not cover you personally so you'd need other insurance for that.
States like Iowa, New Hampshire, and Ohio offer exemptions from insurance if you can show you are responsible with money. Meaning that if you have a steady income and are smart with money, then you likely would be able to pay off any future accident without needing insurance. Though the damages might get wildly expensive, so a liability policy isn't always a bad thing.

Answers
The correct equation of exponential function is \(f(x) = 6 * (\frac{1}{3} )^x\)
What is an exponential function?
An exponential function is one that has the formula f (x) = \(a^{x}\), where x is a variable and a constant that serves as the function's base and must be greater than 0.
Given,
starting value = 6
constant ratio = 1/3
The general form of an exponential function
\(f(x) = ab^{x}\)
where a = starting value i.e when x = 0
b = rate of change in exponential equation
So substituting our given values in the above equation, the exponential function is
\(f(x) = 6 * (\frac{1}{3} )^x\)
Now the value 6 can be divided by 3 only if the value of x = 1
\(f(1) =\frac{6}{3} = 2\)
If x = 5, then equation becomes,
\(f(5) = 6 * (\frac{1}{3} )^5 = \frac{2}{81}\)
So we cannot simply divide 6 by 3 without considering the value of x.
Therefore the correct equation of exponential function is
\(f(x) = 6 * (\frac{1}{3} )^x\)

Find the area of the shaded portion in the equilateral triangle with sides 6. Show all work for full credit.
(Hint: Assume that the central point of each arc is its corresponding vertex.)
Answers
The area of the shaded portion in the equilateral triangle with sides 6 is 9√3 - 36π.
To find the area of the shaded portion in the equilateral triangle, we need to determine the area of the three arcs and subtract it from the area of the equilateral triangle.
First, let's find the area of one arc. Each arc has a radius equal to the length of the side of the equilateral triangle, which is 6. The formula for the area of a sector is A = (θ/360)πr², where θ is the central angle in degrees.
In an equilateral triangle, each interior angle measures 60 degrees, so the central angle of the arc is 120 degrees (360 degrees divided by 3). Plugging these values into the formula, we get A_arc = (120/360)π(6)² = (1/3)π(6)² = 12π.
Since there are three identical arcs, the total area of the arcs is 3 times the area of one arc, which is 3(12π) = 36π.
Now, let's find the area of the equilateral triangle. The formula for the area of an equilateral triangle is A_triangle = (√3/4)s², where s is the length of a side.
Plugging in the value of the side length, we have A_triangle = (√3/4)(6)² = (√3/4)(36) = 9√3.
Finally, we subtract the area of the arcs from the area of the equilateral triangle to find the shaded portion's area: A_shaded = A_triangle - A_arc = 9√3 - 36π.

Suppose that a box contains 8 cameras and that 4 of them are defective. A sample of 2 cameras is selected at random. Define the random variable variable x as the number of defective cameras in the sample. What is the probability distribution for x?
Answers
The probability distribution for x is:
x P(x)
0 0.214
1 0.571
2 0.214
How can we determine the probability distribution for x?Since there are 8 cameras in the box, the total number of ways to choose 2 cameras from the box is given by the combination formula:
C(8,2) = 8!/(2!×(8-2)!) = 28
So there are 28 possible ways to choose a sample of 2 cameras.
Now, let's calculate the probability of each possible value of x:
When x = 0, both cameras in the sample are non-defective. The number of ways to choose 2 non-defective cameras from the 4 non-defective cameras in the box is given by the combination formula:
C(4,2) = 4!/(2!×(4-2)!) = 6
So the probability of x = 0 is:
P(x=0) = (number of ways to choose 2 non-defective cameras)/(total number of ways to choose 2 cameras)
= 6/28
= 0.214
When x = 1, one camera in the sample is defective and the other is non-defective. The number of ways to choose 1 defective camera from the 4 defective cameras in the box and 1 non-defective camera from the 4 non-defective cameras in the box is given by the product of the corresponding combinations:
C(4,1) × C(4,1) = 4×4 = 16
So the probability of x = 1 is:
P(x=1) = (number of ways to choose 1 defective camera and 1 non-defective camera)/(total number of ways to choose 2 cameras)
= 16/28
= 0.571
When x = 2, both cameras in the sample are defective. The number of ways to choose 2 defective cameras from the 4 defective cameras in the box is given by the combination formula:
C(4,2) = 4!/(2!×(4-2)!) = 6
So the probability of x = 2 is:
P(x=2) = (number of ways to choose 2 defective cameras)/(total number of ways to choose 2 cameras)
= 6/28
= 0.214
Therefore, the probability distribution for x is:
x P(x)

Find the value of (f o g)' at the given value.
Answers
To find the value of (f o g)' at a given value, you first need to understand the concept of composite functions and the chain rule of differentiation. Let's break it down step by step.
To find the value of (f o g)' at a given value, you need to evaluate g(x) and f(x), find their derivatives, and use the chain rule to find the derivative of (f o g) at the given value. It is important to understand the concepts of composite functions and the chain rule to be able to solve problems involving these concepts.
What are composite functions? Composite functions are functions that are formed by composing two or more functions. The notation used to denote composite functions is (f o g)(x), which means that the output of function g is used as the input for function f. In other words, we first evaluate g(x), and then use the result as the input for f(x).
What is the chain rule of differentiation? The chain rule of differentiation is a method used to find the derivative of composite functions. It states that if a function is composed of two or more functions, then its derivative can be found by taking the derivative of the outer function and multiplying it by the derivative of the inner function.
To find the value of (f o g)' at a given value, we need to follow these steps:1. Find g(x) and f(x)2. Find g'(x) and f'(x)3. Evaluate g(x) at the given value4. Use the chain rule to find (f o g)' at the given value
step 1: Find g(x) and f(x)Let's say that we have two functions: g(x) = x^2 + 3x + 1 and f(x) = sqrt(x). To find (f o g)(x), we first need to evaluate g(x) and then use the result as the input for f(x). Therefore, (f o g)(x) = f(g(x)) = sqrt(x^2 + 3x + 1)
Step 2: Find g'(x) and f'(x)To find g'(x), we need to take the derivative of g(x) using the power rule and the sum rule. Therefore, g'(x) = 2x + 3To find f'(x), we need to take the derivative of f(x) using the power rule and the chain rule. Therefore, f'(x) = 1/2(x)^(-1/2)
Step 3: Evaluate g(x) at the given valueSuppose we want to find (f o g)' at x = 2. To do this, we need to first evaluate g(x) at x = 2. Therefore, g(2) = 2^2 + 3(2) + 1 = 11
Step 4: Use the chain rule to find (f o g)' at the given value now we can use the chain rule to find (f o g)' at x = 2. Therefore, (f o g)'(2) = f'(g(2)) * g'(2) = 1/2(11)^(-1/2) * (2)(3) = 3/sqrt(11)

Answers
Answer:
BC=26.05
Step-by-step explanation:
by tan(X) rule
tan(61)=47/BC
BC= 47 / tan(61)
BC=26.05
Answer:
BC = 26.05Step-by-step explanation:
Given Information :
Hypotenuse : Not given
Opposite : 47
Adjacent : BC
Angle ( θ) = 61°
Using SOHCAHTOA
\(Tan\: \theta = \frac{Opposite}{Adjacent} \\\\Tan \: 61 = \frac{47}{BC} \\\\1.804 = \frac{47}{BC}\\\\Cross\:Multiply\\1.804BC= 47\\\\Divide\:both\:sides\:by\:1.8 \\\\\frac{1.804BC}{1.804} = \frac{47}{1.804} \\\\BC= 26.05\)
