To answer this question we will use the following trigonometric identity:
\(\sin^2\theta+\cos^2\theta=1.\)Solving the first equation for cosθ we get:
\(\begin{gathered} x-2=4\cos\theta+2-2, \\ x-2=4\cos\theta, \\ \frac{x-2}{4}=\frac{4\cos\theta}{4}, \\ \frac{x-2}{4}=\cos\theta. \end{gathered}\)Solving the second equation for sinθ we get:
\(\begin{gathered} y+5=2\sin\theta-5+5, \\ y+5=2\sin\theta, \\ \frac{y+5}{2}=\frac{2\sin\theta}{2} \\ \frac{y+5}{2}=\sin\theta. \end{gathered}\)Substituting

Answers
The probability that 5 messages are received in 1 hour is is 0.1755 ,the probability that 10 messages are received in 1.5 hours is 0.0858 and the probability that less than 2 messages are received in 1/2 hour is 0.2873
Let X shows the number of messages received per hour. The pdf of X is
\(P(X=x)=\) \(\frac{e^{-5}\cdot 5^{x}}{x!},x=0,1,2,3,....\)
Therefore, the probability that 5 messages are received in a single hour is
\(P(X=5)=\frac{e^{-5}\cdot 5^{5}}{5!}=0.1755\)
(b) Number of message received in 1 hour is 5 so number of message received in 1.5 hour is 7.5. So the probability that 10 messages are received in 1.5 hours is
\(P(X=10)=\frac{e^{-7.5}\cdot 7.5^{10}}{10!}=0.0858\)
(c) Number of message received in 1 hour is 5 so number of message received in 1/2 hour is 2.5. So the probability that less than 2 messages are received in 1/2 hour is
\(P(X < 2)=\frac{e^{-2.5}\cdot 2.5^{0}}{0!}+\frac{e^{-2.5}\cdot 2.5^{1}}{1!}=0.2873\)

What is quotient rule with example?
Answers
The quotient rule states that the derivative of a quotient of two functions is equal to the derivative of the numerator divided by the denominator minus the numerator multiplied by the derivative of the denominator divided by the denominator squared.
The quotient rule, also known as the "rule of quotients", is a fundamental concept in calculus that allows us to differentiate functions that are the ratio of two other functions. It states that if we have two functions, f(x) and g(x), then the derivative of their quotient, f(x)/g(x), can be found using the formula:
(d/dx)(f(x)/g(x)) = (g(x) * df/dx - f(x) * dg/dx) / g(x)^2
In other words, the derivative of the quotient of two functions is equal to the derivative of the numerator divided by the denominator minus the numerator multiplied by the derivative of the denominator divided by the denominator squared.
For example, consider the function h(x) = sin(x) / x. To find the derivative of h(x), we can use the quotient rule:
(d/dx)h(x) = (x * cos(x) - sin(x)) / x^2.
The quotient rule is a fundamental tool in calculus and is used in many real-world applications, including optimization, control theory, and the analysis of physical phenomena.

Answers
The closest answer is 80 cupcakes per minute, so the correct option is .8. The closest answer is 165 minutes, so the correct option is 165.
The throughput capacity of the icing stage can be calculated by dividing the number of cupcakes in a batch (100) by the time required to process each cupcake (1.25 minutes).
Throughput capacity = Number of cupcakes in a batch / Time to process each cupcake
Throughput capacity = 100 cupcakes / 1.25 minutes
Throughput capacity = 80 cupcakes per minute
The closest answer is 80 cupcakes per minute, so the correct option is .8.
The throughput time for a batch of cupcakes is the time required to process the entire batch, including the setup time.
Throughput time = Time for setup + (Number of cupcakes in a batch * Time to process each cupcake)
Throughput time = 40 minutes + (100 cupcakes * 1.25 minutes per cupcake)
Throughput time = 40 minutes + 125 minutes
Throughput time = 165 minutes
The closest answer is 165 minutes, so the correct option is 165.

Solve sin(5x)cos(10x)−cos(5x)sin(10x)=−0.25 for the smallest positive solution. x= Give your answer accurate to two decimal places.
Answers
The smallest positive solution to the equation is \(x \approx 0.05\) (rounded to two decimal places).
To solve the equation \(\sin(5x)\cos(10x) - \cos(5x)\sin(10x) = -0.25\) for the smallest positive solution, we can use trigonometric identities to simplify the equation and then solve for \(x\).
Using the identity \(\sin(A - B) = \sin A \cos B - \cos A \sin B\), we can rewrite the equation as follows:
\(\sin(5x - 10x) = -0.25\)
Simplifying the angle, we have:
\(\sin(-5x) = -0.25\)
Since \(\sin(-\theta) = -\sin(\theta)\), we can rewrite the equation as:
\(-\sin(5x) = -0.25\)
Dividing both sides by -1, we get:
\(\sin(5x) = 0.25\)
To find the smallest positive solution, we can use the inverse sine function (also known as arcsine or sin^(-1)). Applying the inverse sine to both sides, we have:
\(5x = \sin^(-1)(0.25)\)
Using a calculator, we find that \(\sin^(-1)(0.25) \approx 0.2527\) (rounded to four decimal places).
Dividing both sides by 5, we obtain:
\(x = \frac{0.2527}{5}\)
Calculating the result, we find that \(x \approx 0.0505\) (rounded to four decimal places).
Therefore, the smallest positive solution to the equation is \(x \approx 0.05\) (rounded to two decimal places).

Answer:
Worker B needs 9 days to finish the rest of the work
Step-by-step explanation:
Proportions
Worker A finishes a project on his own in 12 days and worker B does the same in 16 days.
Worker A does 1/12 of the project in one day and worker B does 1/16 of the project in one day. When working together, they do
\(\frac{1}{12}+\frac{1}{16}=\frac{7}{48}\)
After 3 days they have completed:
\(3*\frac{7}{48}=\frac{7}{16}\)
parts of the project, this means it still remains:
\(1-\frac{7}{16}=\frac{9}{16}\)
parts of the project and it is done by B alone. Since B does \(\frac{1}{16}\) per day, he now takes
\(\displaystyle \frac{\frac{9}{16}}{\frac{1}{16}}=9\)
days to complete the project.
Worker B needs 9 days to finish the rest of the work

Answers
The statement A is correct option.
What is the vertex of a quadratic function?The vertex of a quadratic equation is the minimum or maximum point of the equation.
Given that, the quadratic function f(x) has a vertex at (1, 6) and opens downward and g(x) = (x - 7)² + 1,
The vertex of f(x) is at (1, 6), we know that a vertical line passing through the vertex is called the axis of symmetry for the parabola.
That mean, axis of symmetry will pass through (1, 6)
Therefore, the axis of symmetry for f(x) is x = 1
And, g(x) = (x - 7)² + 1
= x²+49-14x+1
= x²-14x+50
Vertex = -b / 2a
here, b = -14 and a = 1
Vertex (h, k) = 14 / 2 = 7
To find k, put x = 7 in the equation,
(7-7)²+1 = 1
Therefore, point of the vertex = (7, 1)
That mean axis of the symmetry will pass through (7, 1)
Therefore, axis of the symmetry for g(x) = 7
Hence, the statement A is correct option.

The system of inequalities is:
y ≤ -0.05*x^2 + 6x
y > 1.5x + 45
(30, 90) is not a solution of that system, while (60, 160) is a solution.
How to get the system of inequalities?
We know that the revenue y is given by:
y ≤ -0.05x^2 + 6x
And we know that the costs are 1.5x + 45, and the revenue must be larger than that, so we also have the inequality:
y > 1.5x + 45
So the system is:
y ≤ -0.05*x^2 + 6x
y > 1.5x + 45
Now, the point (30, 90) means that we need to replace x by 30 and y by 90, replacing that in the second inequality, we will get:
90 > 1.5*30 + 45 = 90
90 > 90
This is false, so the point is not a solution of this inequality, meaning that the point is not a solution of the system.
For the second point we do the same: x= 60, y = 160, replacing that in the second inequality we get:
160 > 1.5*60 + 45 = 135
160 > 135
This is true, now we need to check with the other inequality.
160 ≤ -0.05*60^2 + 6*60 = 180
This is also true.

On your trip, you are travelling approximately 8,400,000 m. You estimate the cost of your gas as 72 cents per 1 km. The trip costs you $6,405. Is your estimate correct? What is the difference in costs?
Answers
The difference in costs is $357.
To determine if estimate of the gas cost is correct?To determine if your estimate of the gas cost is correct, we need to calculate the actual cost of the gas for the trip and compare it with the estimated cost.
Since you traveled 8,400,000 m, which is equivalent to 8,400 km, we can find the actual cost of gas for the trip as follows:
Actual cost = 8,400 km * $0.72/km = $6,048
Now we can compare the estimated cost with the actual cost:
Difference in costs = Actual cost - Estimated cost
Difference in costs = $6,048 - $6,405
Difference in costs = -$357
The negative difference in costs indicates that the estimated cost was higher than the actual cost.
In other words, the actual cost of gas for the trip was less than what was estimated. The difference in costs is $357 less than the estimated cost.
