Isaac's kitchen has an area of 54 square feet. The kitchen is 9 times as many square feet as Isaac's pantry. If the pantry is 2 feet wide, what is the length of the pantry?
Answer:
3 Feet
Step-by-step explanation:
Issac's Kitchen Area - 54 sqft
Issac's Pantry Area - 54/9 = 6 sqft (His pantry is 9x smaller than his kitchen)
\(area = length * width\)
Here we have the total area and the width, so we can substitute for finding the length:
\(6 = length * 2\\ \\ = > \frac{6}{2} = length\\ \\ = > length = 3\)
Hence is pantry is 3 feet long.
Solve the differential equation by variation of parameters, subject to the initial conditions
y(0) = 1, y(0) = 0.
25y'' − y = xe^(x/5)
To solve the differential equation y'' - y = xe^(x/5) by variation of parameters with initial conditions y(0) = 1 and y'(0) = 0.25, we get y(x) = (1/5)x^2e^(x/5) + (11/25)e^(x/5) - (1/25)xe^(x/5).
Given differential equation is y'' - y = xe^(x/5). To solve this equation by variation of parameters, we assume the solution to be of the form y(x) = u(x)v1(x) + w(x)v2(x), where v1(x) and v2(x) are linearly independent solutions of the homogeneous equation y'' - y = 0.
The solutions of the homogeneous equation are y1(x) = e^(x/2) and y2(x) = e^(-x/2). Thus, we have v1(x) = e^(x/2) and v2(x) = e^(-x/2).
Using the product rule, we can calculate y'(x) and y''(x) as follows:
y'(x) = u'(x)v1(x) + u(x)v1'(x) + w'(x)v2(x) + w(x)v2'(x)
y''(x) = u''(x)v1(x) + 2u'(x)v1'(x) + u(x)v1''(x) + w''(x)v2(x) - 2w'(x)v2'(x) + w(x)v2''(x)
Substituting these values in the given differential equation, we get:
u''(x)v1(x) + 2u'(x)v1'(x) + u(x)v1''(x) + w''(x)v2(x) - 2w'(x)v2'(x) + w(x)v2''(x) - u(x)v1(x) - w(x)v2(x) = xe^(x/5)
Simplifying the above equation, we get:
u''(x)v1(x) + 2u'(x)v1'(x) + u(x)v1''(x) + w''(x)v2(x) - 2w'(x)v2'(x) + w(x)v2''(x) = xe^(x/5) + u(x)v1(x) + w(x)v2(x)
To solve for the functions u(x) and w(x), we use the following system of equations:
u'(x)v1(x) + w'(x)v2(x) = 0
u'(x)v1'(x) + w'(x)v2'(x) = xe^(x/5) + u(x)v1(x) + w(x)v2(x)
Solving the above system of equations, we get:
u(x) = ∫[-v2(x)(xe^(x/5))] / [v1(x)v2'(x) - v1'(x)v2(x)] dx + C1
w(x) = ∫[v1(x)(xe^(x/5))] / [v1(x)v2'(x) - v1'(x)v2(x)] dx + C2
where C1 and C2 are constants of integration.
Substituting the values of u(x) and w(x) in y(x) = u(x)v1(x) + w(x)v2(x), we get the particular solution of the differential equation.
y(x) = (1/5)x^2e^(x/5)

The larger of two numbers is 17 more than the smaller number. The sum of the two numbers is 71.
Answer:
The smaller number is 27 and the larger number is 44
Step-by-step explanation:
Let x = the larger number
Let y = the smaller number
x + y = 71
x = y + 17 Substitute in y + 17 for x in the first equation.
x + y = 71
y +17 + y = 71 Combine the y's.
2y + 17 = 71 Subtract 17 from both sides of the equation
2y = 54 Divide both sides of the equation by 2
y = 27. Plug 27 in for y for either of the two original equation to find x
x + y = 71
x + 27 = 71 Subtract 27 from both sides of the equation

Find a nonzero vector x perpendicular to the vector v = [1 8 4 8] and u = [5 -9 -4 -9]. X = [__ ___ _____ _____] Hint: Set up a system of linear equations that the components of x satisfy.
To solve for a nonzero vector x that is perpendicular to v = [1 8 4 8] and u = [5 -9 -4 -9], you can set up a system of linear equations that the components of x satisfy.
This system of linear equations can be expressed as follows:1x + 8y + 4z + 8w = 05x - 9y - 4z - 9w = 0To find a nonzero vector x that is perpendicular to v and u, you need to find the null space of the coefficient matrix of the above system of linear equations. In matrix form, the above system can be written as follows:
[1 8 4 8; 5 -9 -4 -9] [x; y; z; w] = [0; 0]The augmented matrix of the above system is:[1 8 4 8 | 0; 5 -9 -4 -9 | 0]You can perform elementary row operations on the augmented matrix to obtain the reduced row-echelon form of the matrix. Doing so gives you:[1 0 -1/3 -1 | 0; 0 1 4/9 1 | 0]The above matrix represents the system of equations:1x - (1/3)z - w = 01y + (4/9)z + w = 0Now, you can express x, y, z, and w in terms of the free variable(s). Let z = 3t and w = -9s. Then, x = t and y = (-4/9)t, where t and s are nonzero constants. Thus, the general solution to the system of equations is:x = t, y = (-4/9)t, z = 3t, w = -9sTherefore, a nonzero vector x that is perpendicular to v and u is given by:[x; y; z; w] = [t; (-4/9)t; 3t; -9s] = t[1; -4/9; 3; 0] where t is any nonzero constant.

what is triangle ?
A triangle is a three-sided polygon, which is a closed two-dimensional shape with straight sides. It is one of the basic shapes in geometry and is used in various fields such as mathematics, physics, engineering, and architecture.
In the given question,
The student's mistake might have been that she assumed that there is only one possible triangle with angle measures of 90 degrees, 30 degrees, and 60 degrees. However, this is not true. In fact, there are infinitely many triangles with these angle measures, since the length of the sides can vary.
The most well-known triangle with angle measures of 90 degrees, 30 degrees, and 60 degrees is the 30-60-90 triangle, which has specific side ratios of 1:sqrt(3):2. But this is just one possible example of a triangle with those angle measures, and it is not the only one.
It is important to note that in a triangle, the angles determine the shape and the side lengths determine the size. Therefore, if two triangles have the same angle measures, they will be similar, but they may not necessarily be congruent unless they also have the same side lengths.

Consider a 2-layer channel with a flat bottom. Consider a domain infinitively wide in
y (practically when you have to write the dispersion relation only kx remains and you can
neglect ly). Show that, in presence of rotation, there is a minimal length for baroclinic
instability to take place
Rhines criterion implies that there is a minimum length scale for baroclinic instability to take place, which is given by:
L = 2π/kx = 2π[(N² - f₂²)/(f₁² - f₂²)]¹/²
In a 2-layer channel with a flat bottom and infinite width in y, the dispersion relation for baroclinic instability is given by:
ω = kx[(f₁² - f₂²)/(N² - f₂²)]¹/²
Where ω is the frequency, kx is the wavenumber in the x-direction, f₁ and f₂ are the Coriolis parameters for the upper and lower layers, and N is the buoyancy frequency.
In the presence of rotation, the minimum length for baroclinic instability to take place is determined by the condition that the frequency ω must be positive. This means that:
(f₁² - f₂²)/(N² - f₂²) > 0
or equivalently:
f₁ > (N²f₂)¹/²
This condition implies that the Coriolis parameter in the upper layer must be greater than the square root of the product of the buoyancy frequency and the Coriolis parameter in the lower layer. This is known as the "Rhines criterion" and represents a necessary condition for the development of baroclinic instability in rotating fluids.
Furthermore, the Rhines criterion implies that there is a minimum length scale for baroclinic instability to take place, which is given by:
L = 2π/kx = 2π[(N² - f₂²)/(f₁² - f₂²)]¹/²
This length scale represents the typical size of the eddies that form due to baroclinic instability in rotating fluids, and is proportional to the inverse square root of the difference between the Coriolis parameters in the upper and lower layers.

This was a 25% increase since the dog's last veterinarian appointment that was in March. How much did Fred's dog weigh at the veterinarian appointment in March?
The weight of Fred's dog at the veterinarian appointment in March is 36 pounds.
How much did Fred's dog weigh at the veterinarian appointment in March?Fred's dog weight in September= 45 pounds
Percentage increase= 25%
Fred's dog weight in March = x
45 = x + (25% of x)
45 = x + 0.25x
45 = 1.25x

Function aligns value from one set to another. The function will have a removable discontinuity at x = -3.
What is Function?A function assigns the value of each element of one set to the other specific element of another set.
As the function is given to us,
\(F(x) = \dfrac{(x^2+12x+27)}{(x^2+4x+3)}\)

200 is the mean absolute deviation. Therefore, choice three (200) is the right one.
How to calculate the mean absolute deviation
The absolute difference between the predicted and actual values must be determined, added together, and divided by the total number of periods.
Forecasted values are as follows: 1,500 and 1,400
Values in actuality: 1,200 and 1,500
Absolute differences:
|1,500 - 1,200| = 300
|1,400 - 1,500| = 100
Now, we calculate the MAD:
MAD = (300 + 100) / 2 = 400 / 2 = 200
Therefore, 200 is the mean absolute deviation. Therefore, choice three (200) is the right one.
