The given function is [tex]f(x,y) = x^2 + y^2[/tex].
To find the gradient of f at the point (x0, y0), we take the partial derivatives of f with respect to x and y:
[tex]$$\nabla f(x0,y0) = \left(\frac{\partial f}{\partial x}, \frac{\partial f}{\partial y}\right) = \left(2x0, 2y0\right)$$[/tex]
The rate of increase of $f$ at the point (x0, y0) in the direction (u,v) is given by the dot product of the gradient and the direction vector:
[tex]$$\nabla f(x0,y0) \cdot (u,v) = 2x0u + 2y0v$$[/tex]
The direction of maximum rate of increase at (x0, y0) is the direction of the gradient, which is (2x0,2y0). The rate of increase in this direction is the length of the gradient vector, which is given by:
[tex]$$||\nabla f(x0,y0)|| = \sqrt{(2x0)^2 + (2y0)^2} = 2\sqrt{x0^2 + y0^2}$$[/tex]

What is differential equation?An equation known as a differential equation describes the derivative or derivatives of an unknown function. Because they are equations involving a function and its derivatives (where the variable is a function rather than a number) (the functions obtained by differentiating it). Save this response. Common differential equations are used in everyday life to compute the flow of electricity, the motion of an item back and forth like a pendulum, and to illustrate the principles of thermodynamics. Additionally, in medical terminology, they are employed to graphically monitor the progression of illnesses.
Given that,

Answer:
B. 10
Step-by-step explanation:
We can solve this fast by adding the points from the stars and ships together, then subtracting that number from the total 500 points Mateo earnd.
So it would look like this:
180+270=450
500-450=50
So if Mateo scored 50 points from saving prisoners and save is worth 5 points each, we can do 50÷5=10.

The solution to the system is x1 = -4, x2 = 10.
What is the solution to the system?
A solution to a system of equations is a set of values for the variable that satisfy all the equations simultaneously. In order to solve a system of equations, one must find all the sets of values of the variables that constitute solutions to the system. (5, 4) is a solution of the first equation, but not the second.
The given system can be converted to an augmented matrix as follows:
[ 2 1 | 2 ]
[-1 -1 -1 | 6 ]
To find all solutions, we will reduce the system to echelon form and back substitute.
Step 1: Echelon Form
We can perform row operations to reduce the matrix to echelon form:
[ 2 1 | 2 ] R1 = R1 * 1/2
[-1 -1 -1 | 6 ]
[ 1 1/2 | 1 ] R2 = R2 + R1
[ 0 -3/2 -1 | 5 ]
Step 2: Reduced Row Echelon Form
Next, we can perform additional row operations to reduce the matrix to a reduced row echelon form:
[ 1 1/2 | 1 ] R2 = R2 * 2
[ 0 1 | 10 ]
The reduced row echelon form of the matrix represents the system of equations in a simplified form and the solution to the system can be obtained by back substituting.
Step 3: Back Substituting
x2 = 10
x1 = 1 - 1/2 x2 = 1 - 1/2 * 10 = 1 - 5 = -4
Therefore, the solution to the system is x1 = -4, x2 = 10.

What is triangle?Three vertices make up a triangle, a three-sided polygon. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.
∠a and 30° are vertical angles and vertical angles are equal
∠a = 30°
We have a triangle with a, b and a right angle. Triangles have angles that add to 180°.
∠a + ∠b + 90° = 180°
30° + ∠b + 90° =180°
120° + ∠b = 180
∠b = 180° - 120°

solve the initial-value problem answer: xy = y x^2 sinx, y(pi/3) = 0
The value of the constant in the function is c = -√3π²/6(3-π).
A differential equation is an equation that relates an unknown function and one or more of its derivatives. The equation dy/dx = f(x) is a simple example of a differential equation. Solving this equation means finding a function y with a derivative f. Therefore, the solutions of dy/dx are the antiderivatives of f. If F is one antiderivative of f, every function of the form y = f(x) + c is a solution of that differential equation.
Initial-value problems arise in many applications. Next we consider a problem in which a driver applies the brakes in a car. We are interested in how long it takes for the car to stop. Recall that the velocity function v(t) is the derivative of a position function s(t), and the acceleration a(t) is the derivative of the velocity function. In earlier examples in the text, we could calculate the velocity from the position and then compute the acceleration from the velocity. In the next example, we work the other way around. Given an acceleration function, we calculate the velocity function. We then use the velocity function to determine the position function.
The given equation is xy = y + x² sinx
⇒ xy - y = x² sinx
⇒ y(x-1) = x² sinx
⇒ y = x² sinx/(x-1) +c
Also, y(π/3) = 0
Put x = π/3 in above equation:
y(π/3) = (π/3) ² sin(π/3) /((π/3)-1) + c = 0
After solving the above equation, we get c = -√3π²/6(3-π)
Thus, the value of the constant in the function is c = -√3π²/6(3-π).

to solve this problem we have to analyze the information given:
Candy available: six 100-piece bags
Number of children: 20
Pieces of candy for each child: 6
So, we have to calculate the total amount of candy available by multiplying the pieces of candy that each bag has (100) by the number of bags(6)
100 x 6 = 600
Then, we have to multiply the number of children (20) by the number of pieces of candy that each one receives (6) and then subtract that number to the number of pieces of candy available.
20x 6 = 120

How you can create a histogram?Determine the range of the data: 0.6 to 4.7.
Divide the range by the number of classes (5) to find the class width: (4.7 - 0.6) / 5 = 0.76.
Determine the lower limits of each class by starting at the minimum value (0.6) and adding the class width repeatedly: 0.6, 1.36, 2.12, 2.88, 3.64, 4.4.
Count the number of data values that fall into each class and record it in a table.
Draw a bar for each class using the lower limit of the class as the x-axis value and the height of the bar equal to the number of data values in the class.
After creating the histogram, you can easily find the percentage of dogs that are walked at least 1.5 hours but under 4.2 hours per week by counting the number of data values in the appropriate class and dividing by the total number of data values, then multiplying by 100.

find mean in the above distribution
The mean in the above distribution is 1.84
How to find mean in the above distributionFrom the question, we have the following parameters that can be used in our computation:
The figure
The mean value is then calculated as
Mean = SUm of the product of children and familes/Sum of families
So, we have
Mean = (0 * 23 + 1 * 19 + 2 * 29 + 3 * 9 + 4 * 20)/(23 + 19 + 29 + 9 + 20)
Evaluate
Mean = 1.84
Hence, the mean is 1.84

Find the exact length of line segment PQ
The exact length of line segment PQ is 22.4.
What is the distance between two points ( p,q) and (x,y)?The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:
[tex]D = √[(x-p)² + (y-q)²] D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]
Given;
p(x,y)=(17,4)
m(x,y)=(-2,16)
Now,
[tex]D = √[(x-p)² + (y-q)²] D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]
D^2= (-2-17)^2+(16-4)^2
D^2=361+144
D^2= 505
D=22.4
Therefore, the distance will be 22.4
