у=-3x+3
y = -9x + 15
Answers
Answer:
(2, - 3 )
Step-by-step explanation:
Given the 2 equations
y = - 3x + 3 → (2)
y = - 9x + 15 → (2)
Substitute y = - 3x + 3 into (2)
- 3x + 3 = - 9x + 15 ( add 9x to both sides )
6x + 3 = 15 ( subtract 3 from both sides )
6x = 12 ( divide both sides by 6 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (1)
y = - 3(2) + 3 = - 6 + 3 = - 3
solution is (2, - 3 )

Enter the expression asin(x)+15 , where asin(x) is the inverse sine function. Alternatively, you may enter the inverse sine function in either of the following forms, which are also accepted: arcsin(x) or sin−1(x)
Answers
The graph of asin(x) + 15 is located 15 units upward as compared to asin(x).
For a function to have an inverse function, it must be one-to-one, that is, it must pass the Horizontal Line Test that establishes that a function has an inverse function if and only if no horizontal line intersects the graph of at more than one point. The function asin(x) does not pass the test because different values of \(x\) yield the same values of \(y\).
However, if you restrict the domain to the interval:
\(-\pi /2 \leq x\leq \pi /2\)
as shown in Figure, then you have the inverse of the sine function.
So in Figure is shown the graph of:

Answers
The average time between fireworks is 4 seconds.
The given problem is a uniform distribution problem.
Uniform distribution is the probability distribution, which states that all outcomes of a random variable are equally likely. The mean or the average of the uniform distribution formula is (a + b) / 2, where a is the lower limit and b is the upper limit of the interval.
The given problem states that the time between fireworks follows uniform distribution between one and seven seconds. Hence, the lower limit (a) is 1 and the upper limit (b) is 7.
The mean or the average time between the fireworks can be calculated using the formula; (a + b) / 2.(a) Average time between fireworks = (1 + 7) / 2 = 4 seconds.

Find the circulation and flux of the field F = xi +yj around and across the closed semicircular path that consists of the semicircular arch r1(t)=(a cos t)i+(a sin t)j,O ≤ t ≤ = π, followed by the line segment r2(t)= ti, -a ≤ t ≤ = a
Answers
The circulation and the flux of the field F -
F = xi + yj = (a cos t)i + (a sin t)j
What is Line segment ?
In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints.
A closed line segment includes both endpoints, while an open line segment excludes both endpoints; a half-open line segment includes exactly one of the endpoints
To find the circulation and flux of the field F = xi + yj around and across the closed semicircular path and line segment, we need to calculate the line integral of F along the path.
First, let's parameterize the path:
For the semicircular arch:
r1(t) = (a cos t)i + (a sin t)j, 0 ≤ t ≤ π
For the line segment:
r2(t) = ti, -a ≤ t ≤ a
Circulation:
The circulation of the vector field F around the closed path is given by the line integral of F along the path:
Circulation = ∮ F · dr
For the semicircular arch:
∮₁ F · dr = ∫₀ᴾ F · dr₁
where dr₁ is the differential arc length along the semicircular path.
For the line segment:
∮₂ F · dr = ∫₋ₐᵃ F · dr₂
where dr₂ is the differential displacement along the line segment.
Flux:
The flux of the vector field F across the closed path is given by the line integral of F dotted with the outward unit normal vector along the path:
Flux = ∮ F · dA
where dA is the differential area element.
For the semicircular arch:
∮₁ F · dA = ∫₀ᴾ F · dA₁
For the line segment:
∮₂ F · dA = ∫₋ₐᵃ F · dA₂
Since the field F = xi + yj, we have:
F = xi + yj = (a cos t)i + (a sin t)j

What is addition?Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.
here, we have,
Let's remember that the complete revolution of the wheel is 360 degrees, and the distance traveled by a complete revolution is the length of the circumference: 2*pi*radius.
The inicial height of the point is 6 ft, and the radius of the wheel is 1 ft.
When the distance traveled is 0, the wheel turned 0 degrees, and the point will be in its inicial position (the lower position of the wheel), which is 6 feet high.
So the height will be a = 6 + 0 = 6 ft
When the distance traveled is pi/2, the wheel turned 90 degrees, and the point will be half the complete height of the wheel, which is 2 feet.
So the height will be b = 6 + 1 = 7 ft
When the distance traveled is pi, the wheel turned 180 degrees, and the point will be at the top of the wheel, which is 2 feet higher than the lower point of the wheel.
So the height will be c = 6 + 2= 8 ft
When the distance traveled is 3pi/2, the wheel turned 270 degrees, and the point will be half the complete height of the wheel, which is 2 feet.
So the height will be d = 6 + 1 = 7 ft
When the distance traveled is 2pi, the wheel turned 360 degrees, and the point will be in its inicial position (the lower position of the wheel), which is 6 feet high.
So the height will be e = 6 + 0 = 6 ft

Find the slope of the line passing through the points (-6,6) and (4,-7)
Answers
Answer:
m = -13/10
Step-by-step explanation:
Madison, imagine that you're moving from (-6, 6) to (4, -7) with interest in knowing how much x (the run) and y (the rise) change.
In the first instance, x increases by 10 from -6 and +4. Simultaneously, y decreases by 13 from 6 to -7.
Thus the slope is m = rise / run = m = -13/10

If the total debt ratio is 0.5. what is the debt-equity ratio? (Assume no leases.)
a. 2.0
b. 4.0
c. 1.0
d. 0.5
Answers
The consumption next year for Ms. Anderson will be approximately $56,363.64 which is not in options, and the debt-equity ratio, based on a total debt ratio of 0.5, so the answer is option d.
To answer the first question, we need to calculate the consumption next year based on the given information. We can use the concept of present value to determine the amount.
The present value formula is:
Present Value = Future Value / (1 + Interest Rate)^n
Where:
Future Value is the amount to be received in the future
Interest Rate is the rate of return or interest rate per period
n is the number of periods
Given that Ms. Anderson has an income of $40,000 next year and the market interest rate is 10 percent, we can calculate the present value of $40,000:
Present Value = $40,000 / (1 + 0.10)^1
Present Value = $40,000 / 1.10
Present Value ≈ $36,363.64
Since Ms. Anderson consumes $80,000 this year and her present income next year is approximately $36,363.64, her consumption next year will be the sum of her present income and the remaining amount:
Consumption next year = Present income + Remaining amount
Consumption next year = $36,363.64 + ($80,000 - $60,000)
Consumption next year = $36,363.64 + $20,000
Consumption next year = $56,363.64
Therefore, the consumption next year will be approximately $56,363.64. None of the provided options match this amount, so it seems there might be an error in the answer choices.
Given that the total debt ratio is 0.5, it implies that the total debt is half of the total equity.
The debt-equity ratio is calculated by dividing the total debt by the total equity:
Debt-Equity Ratio = Total Debt / Total Equity
Substituting the given information, we have:
Debt-Equity Ratio = 0.5 * Total Equity / Total Equity
The term "Total Equity" cancels out, resulting in:
Debt-Equity Ratio = 0.5
Therefore, the correct answer is option d. 0.5.

Answers
In the given observations, we are provided with several terms related to oxidation and asked to match them to appropriate blanks in the provided sentences.
First, let's consider the term "oxidation by oxygen from the air". This term refers to a process by which oxygen molecules from the air react with other molecules, such as those found in our bodies, to transfer electrons and produce new compounds. This process is important in many biological systems, such as respiration, where oxygen is used to produce energy.
Next, let's look at the term "D-3-hydroxyacyl-ACP". This term refers to a specific molecule that is involved in the synthesis of fatty acids in the body. During this process, the molecule undergoes several steps of oxidation and reduction, which ultimately result in the formation of new fatty acids.
The term "decarbonylation induced by NADPH" refers to a specific type of reaction that involves the removal of a carbonyl group from a molecule. This reaction is often catalyzed by enzymes and can be an important step in the synthesis of many different types of compounds.
Finally, the term "acyl-ACP acyl-KS" refers to two different types of molecules that are involved in the synthesis of fatty acids. These molecules are important intermediates in the process of oxidation and reduction that ultimately leads to the formation of new fatty acids.

Adult tickets to the fall play cost $8 and student tickets cost $4. The drama class sold 30 more adult tickets than student tickets to the fall play. If the class collected 840 from ticket sales, how many adult tickets were sold?
Answers
The number of adult tickets that were sold would be = 435 tickets.
What is a ticket?A ticket is an official document that gives an individual access to an event.
The cost of adult tickets = $8
The cost for student tickets = $4
The number of students tickets sold = X
The number of adults tickets sold = X +30
The told number of tickets sold = 840
To find X;
X + X + 30 = 840
2x + 30 = 840
2x = 840-30
2x = 810
X = 810/2
X = 405

Answers
The sample variance for the given data is 4.4 minutes. This corresponds to option e. in the list of choices provided.
The sample variance is a measure of how much the individual data points in a sample vary from the mean.
It is calculated by finding the average of the squared differences between each data point and the mean.
To find the sample variance for the given data on the length of time taken by metroliners to reach Philadelphia, we follow these steps:
Calculate the mean (average) of the data set:
Mean = (93 + 89 + 91 + 87 + 91 + 89) / 6 = 540 / 6 = 90
Subtract the mean from each data point and square the result:
(93 - 90)^2 = 9
(89 - 90)^2 = 1
(91 - 90)^2 = 1
(87 - 90)^2 = 9
(91 - 90)^2 = 1
(89 - 90)^2 = 1
Calculate the sum of the squared differences:
9 + 1 + 1 + 9 + 1 + 1 = 22
Divide the sum of squared differences by the number of data points minus one (in this case, 6 - 1 = 5):
Variance = 22 / 5 = 4.4
