Graph the system of linear inequalities.
y < −x + 3
y ≥ 2x − 1
Give two ordered pairs that are solutions and two that are not solutions.
Answers
In the given system of linear inequalities,
Solutions: (1, 0), (-2, 5)
Non-solutions: (2, 0), (0, 1)
To graph the system of linear inequalities, we will plot the boundary lines for each inequality and shade the appropriate regions based on the given inequalities.
1. Graphing the inequality y < −x + 3:
To graph y < −x + 3, we first draw the line y = −x + 3. This line has a slope of -1 and a y-intercept of 3. We can plot two points on this line, for example, (0, 3) and (3, 0), and draw a dashed line passing through these points. Since y is less than −x + 3, we shade the region below the line.
2. Graphing the inequality y ≥ 2x − 1:
To graph y ≥ 2x − 1, we first draw the line y = 2x − 1. This line has a slope of 2 and a y-intercept of -1. We can plot two points on this line, for example, (0, -1) and (1, 1), and draw a solid line passing through these points. Since y is greater than or equal to 2x − 1, we shade the region above the line.
Now let's find two ordered pairs that are solutions and two that are not solutions.
Ordered pairs that are solutions:
- (1, 0): This point satisfies both inequalities. Plugging in the values, we get y = -1 and y ≥ 1, which are both true.
- (-2, 5): This point satisfies both inequalities. Plugging in the values, we get y = 7 and y ≥ 3, which are both true.
Ordered pairs that are not solutions:
- (2, 0): This point does not satisfy the first inequality y < −x + 3 since 0 is not less than -2 + 3.
- (0, 1): This point does not satisfy the second inequality y ≥ 2x − 1 since 1 is not greater than or equal to -1.
By graphing the system of linear inequalities and examining the solutions and non-solutions, we have:
Solutions: (1, 0), (-2, 5)
Non-solutions: (2, 0), (0, 1)

Help! What does the bracket mean and how do I do the questions?
Answers
Answer:
maybe it meane 11/a
Step-by-step explanation:
Answer:
The bracket is the binomial.
The definition is: [tex]\binom{n}{k} = \frac{n!}{k!\cdot (n-k)!}[/tex]
Note that [tex]\binom{n}{k} = \binom{n}{n-k}[/tex]
The meaning is "if we have n elements, how many ways are there to choose k of them?" From this definition it should be obvious that [tex]\binom{n}{k} = \binom{n}{n-k}[/tex] - if you're picking k, it's just as many ways as choosing the (n-k) that you're not picking.
The coefficient can be found by realizing that to get x^9, we need to choose (from the full multiplication):
9 brackets to provide x2 brackets to provide the number 3There's [tex]\binom{11}{9}[/tex] ways to do that, so the component for x^9 will be:
[tex]\binom{11}{9} \cdot 3^2 \cdot x^9 = \frac{11!}{2!\cdot 9!} \cdot 3^2 \cdot x^9 = \frac{10\cdot 11}{2} \cdot 3^2 \cdot x^9 = 55 \cdot 9 \cdot x^9 = 495x^9[/tex]
So:
a = 2
Coefficient is 495
Snowy's Snowboard Co. manufactures snowboards. The company used the function P(x) = -5x2 -30% + 675 to model its profits, where P(x) is the profit in thousands of dollars and x is the number of snowboards sold in thousands. How many snowboards must be sold for the company to break even?
Answers
The number of snowboards that must be sold for the company to break even is: 9000
How to solve Profit Functions?The function that models the profit is given as:
P(x) = -5x² - 30x + 675
where:
P(x) is the profit in thousands of dollars
x is the number of snowboards sold in thousands
For the company to break even, it means that P(x) = 0. Thus:
-5x² - 30x + 675 = 0
Using quadratic formula to solve this gives us":
x = [-(-30) ± √((-30)² - 4(-5 * 675)]/(2 * -5)
x = 9
This is in thousands and means the break even will be when the sold amount is 9000 snowboards

a general solution of the differential equation x′(t)=ax is given by x(t)=c1x1(t) c2x2(t), where a matrix A = [0 -1; 1 0]?
Answers
The general solution of the differential equation x'(t) = Ax(t), where A is the matrix [0 -1; 1 0], is x(t) = [(c₁² - c₂² + 2ic₁c₂)[tex]e^{(it)[/tex] + (2c₁c₂ - c₁² + c₂²)[tex]e^{(it)[/tex]][1, i].
To solve the differential equation x'(t) = Ax(t), where A is the given matrix [0 -1; 1 0], we can use the method of finding the eigenvalues and eigenvectors.
Step 1: Find the eigenvalues λ of the matrix A by solving the characteristic equation |A - λI| = 0.
The characteristic equation for A is:
|0-λ -1| = 0
|1 0-λ|
Expanding the determinant gives:
(-λ)(-λ) - (-1)(1) = 0
λ² + 1 = 0
Solving the equation, we get two eigenvalues: λ₁ = i and λ₂ = -i.
Step 2: Find the eigenvectors corresponding to each eigenvalue.
For λ₁ = i:
(A - λ₁I)u₁ = 0
|0- i -1| |x₁| = |0|
|1 0- i| |x₂| |0|
Simplifying the equation gives:
-ix₁ - x₂ = 0
x₁ - ix₂ = 0
Solving this system of equations, we get the eigenvector u₁ = [1, i].
For λ₂ = -i:
(A - λ₂I)u₂ = 0
|0+i -1| |x₁| = |0|
|1 0+i| |x₂| |0|
Simplifying the equation gives:
ix₁ - x₂ = 0
x₁ + ix₂ = 0
Solving this system of equations, we get the eigenvector u₂ = [1, -i].
Step 3: Write the general solution as x(t) = c₁x₁(t) + c₂x₂(t), where c₁ and c₂ are constants.
The general solution to the differential equation x'(t) = Ax(t) is:
x(t) = c₁[1, i][tex]e^{(i\lambda_1 t)[/tex] + c₂[1, -i][tex]e^{(i\lambda_2 t)[/tex]
= c₁[1, i][tex]e^{(it)[/tex] + c₂[1, -i][tex]e^{(it)[/tex]
Expanding and simplifying the solution:
x₁(t) = c₁[tex]e^{(it)[/tex] + c₂[tex]e^{(it)[/tex]
x₂(t) = ic₁[tex]e^{(it)[/tex] - ic₂[tex]e^{(it)[/tex]
Therefore, the general solution is:
x(t) = c₁[c₁[tex]e^{(it)[/tex] + c₂[tex]e^{(it)[/tex]][1, i] + c₂[ic₁[tex]e^{(it)[/tex] - ic₂[tex]e^{(it)[/tex]][1, -i]
= (c₁c₁[tex]e^{(it)[/tex] + c₁c₂[tex]e^{(it)[/tex] + ic₁c₁[tex]e^{(it)[/tex] - ic₁c₂[tex]e^{(it)[/tex])[1, i] + (ic₁c₁[tex]e^{(it)[/tex] - ic₁c₂[tex]e^{(it)[/tex] - c₂c₁[tex]e^{(it)[/tex] - c₂c₂[tex]e^{(it)[/tex])[1, -i]
= [(c₁² - c₂² + 2ic₁c₂)[tex]e^{(it)[/tex] + (2c₁c₂ - c₁² + c₂²)[tex]e^{(it)[/tex]][1, i]

Step-by-step explanation:
Just got it on plato your welcome:)
The segments formed by each transversals and the three parallel lines are
proportional according to the three parallel lines theorem.
The observations are;
The parallel lines divide the transversals in equal proportions, such that the ratio of the lengths of each transversal are equal.[tex]\displaystyle \mathrm{ Ratio \ of \ the \ segments ;\ }\frac{\overline{CB}}{\overline{AB}} = \frac{\overline{EF}}{\overline{DE}}[/tex]Reasons:
The question is a four part question
Let the equations of the parallel lines be as follows;
Line, x; y = x
Line, y; y = x + 1
Line z; y = x + 2
The points at which transversal 1 intersect the lines x, y, and z, are;
A(0.4, 0.4), B(0.6, 1.6), and C(0.8, 2.8)
The length of segment [tex]\overline{AB}[/tex] = √((0.6 - 0.4)² + (1.6 - 0.4)²) = 0.2·√(37)
The length of segment [tex]\mathbf{\overline{CB}}[/tex] = √((0.8 - 0.6)² + (2.8 - 1.6)²) = 0.2·√(37)
The ratio of the lengths of the segment formed by transversal 1 is therefore;
[tex]\sqrt{x} \displaystyle Ratio \ of \ the \ length \ of \ the \ segments = \mathbf{\frac{\overline{CB}}{\overline{AB}}} =\frac{2 \cdot \sqrt{37} }{2 \cdot \sqrt{37} } = 1[/tex]
The points at which transversal 2 intersect the lines x, y, and z, are;
D(1.1, 3.1), E(1.3, 2.3), and F(1.5, 1.5)
The length of segment [tex]\overline{DE}[/tex] = √((1.3 - 1.1)² + (2.3 - 3.1)²) = 0.2·√(17)
The length of segment [tex]\overline{EF}[/tex] = √((1.5 - 1.3)² + (1.5 - 2.3)²) = 0.2·√(17)
[tex]\sqrt{x} \displaystyle Ratio \ of \ the \ length \ of \ the \ segments = \mathbf{\frac{\overline{EF}}{\overline{DE}}} =\frac{0.2 \cdot \sqrt{17} }{0.2 \cdot \sqrt{17} } = 1[/tex]
Therefore;
[tex]\displaystyle \frac{\overline{CB}}{\overline{AB}} = \frac{\overline{EF}}{\overline{DE}} = 1[/tex]Which gives;
The proportion with which the parallel lines divide the transversals are equal.The ratio of the lengths for each transversal are equal.The the comparison can also be made with the triangle proportionality theorem.

Consider the function f(3) = 1/cose. Estimate the condition number for the problem of evaluating this function near the point 1.5708. Calculate the input and output relative errors whe
Answers
The condition number for the problem of evaluating the function f(x) = 1/cos(x) near the point x = 1.5708 is approximately 10 raised to power 16
This means that a small change in the input x can cause a large change in the output f(x).
The condition number of a function is a measure of how sensitive the function is to changes in its input. The larger the condition number, the more sensitive the function is to changes in its input. The condition number for the function f(x) = 1/cos(x) can be estimated as follows:
K = |f'(x)| / |f(x)|
where f'(x) is the derivative of f(x) and f(x) is the value of f(x) at the point x. At the point x = 1.5708, f'(x) = -1 and f(x) = 0.017453292519943295. Therefore, the condition number is approximately:
K = |-1| / |0.017453292519943295| = 10 raised to power 16
This means that a small change in the input x can cause a large change in the output f(x). For example, if the input x is changed by 1e raised to power of -16, the output f(x) will change by approximately 10 raised to power of 16.
This large condition number is due to the fact that the function f(x) = 1/cos(x) is very sensitive to changes in the input x near the point x = 1.5708. This is because the cosine function is very close to zero at this point.

Rotation of 180° clockwise around the origin
Step-by-step explanation: if you rotate the first triangle 90 degrees, it will be in the lower quarter, so you need to rotate it 1 more time.
The transformations are clockwise rotation 180° and translation down by 1 unit.
What is rotation?Rotations are transformations that turn a shape around a fixed point. To rotate a shape we need: a centre of rotation. an angle of rotation (given in degrees) a direction of rotation – either clockwise or anti-clockwise.
From the given graph, the coordinates of triangle PQR are P(2, 1), Q(4, 6) and R(4, 1).
Rotating a point that has the coordinates (x,y) 180° about the origin in a clockwise direction, we have (-x,-y).
Here,
P(2, 1) → P'(-2, -1)
Q(4, 6) → Q'(-4, -6)
R(4, 1) → R'(-4, -1)
The translation down by 1 unit, we get (x, y-k)
P'(-2, -1) → P'(-2, -2)
Q'(-4, -6) → Q'(-4, -7)
R'(-4, -1) → R'(-4, -2)
The coordinates of triangle P'Q'R' are P'(-2, -2), Q(-4, -7) and R'(-4, -2)
Therefore, the transformations are clockwise rotation 180° and translation down by 1 unit.

Answers
The spring constant, k = 27 N/m. The system is critically damped. The position function of the object is x(t) = e-6t(cos √3t + √3/3 sin √3t).
(a) Given, m = 1 kg, c = 12 and the spring is stretched 0.5 meters by a force of 13.5 N. We need to find the spring constant k. Let's consider the force applied on the spring, F = -kx
Here, x = 0.5 m and F = 13.5 N. So, 13.5 = -k (0.5) => k = -27 N/m
Since, we cannot have negative spring constant. Therefore, k = 27 N/m.
(b) The given differential equation is x" + 12x' + 27x = 0.
On comparing with the general equation of a damped mass-spring system, we get m = 1 kg, c = 12, k = 27.
The damping factor is defined as β = c/2m = 6.
Using the damping factor we can determine the type of the system. c2 - 4mk > 0 - overdamped systemc2 - 4mk = 0 - critically damped systemc2 - 4mk < 0 - underdamped system In this case, c2 - 4mk = 12^2 - 4(1)(27) = 0
This indicates that the system is critically damped.
(c) The general equation for a damped mass-spring system is x(t) = e-βt(A cos ωdt + B sin ωdt)
Where, A and B are constants that are determined using initial conditions. x(0) = A = 1 and x'(0) = -βA + ωdB/dt = -2 => B = (1/ω) (-βA + 2)
Now, we need to determine ω.ω2 = k/m - β2/4m2 = 27/1 - (12/2)2/4(1)(27) = 3ω = √3
Substitute the value of A, B and ω in the general equation, we get x(t) = e-6t(cos √3t + √3/3 sin √3t)
Hence, the position function of the object is x(t) = e-6t(cos √3t + √3/3 sin √3t).

Average amount of milk used for an order of pancakes = {1/2c + 1/4c + 1/2c + 3/4c + 1/2c + 3/4c + 1/2c + 1/4c + 1/2c + 1/2c} ÷ 10
= {6(1/2c) + 2(1/4c) + 2(3/4c)} ÷ 10
= {6/2c + 2/4c + 6/4c} ÷ 10
= {3c + 1/2c + 3/2c} ÷ 10
= {(6+1+3) / 2}c ÷ 10
= 10/2c ÷ 10
= 5c ÷ 10
= 5/10c
= 1/2c
The average amount of milk used for an order of pancakes = 1/2c

23. The coordinates when the point (-4, 2) is reflected about the y-axis are: (a) (-2,4) (c) (4,2) (b) (4, -2) (d) (-4,-2) 24. The annual precipitation for one city is normally distributed with a mean
Answers
the coordinates of the reflected point are (4, 2).
When a point is reflected about the y-axis, the x-coordinate is negated while the y-coordinate remains the same.
The original point is (-4, 2). If we reflect this point about the y-axis, the x-coordinate becomes positive, and the y-coordinate remains unchanged.
Negating the x-coordinate, we get:
x-coordinate: -(-4) = 4
y-coordinate: 2 (unchanged)
Given the point (-4, 2), reflecting it about the y-axis would result in the x-coordinate changing its sign while the y-coordinate remains unchanged.
Therefore, the coordinates of the reflected point are (4, 2).
Among the options provided, the correct answer is (c) (4, 2).
