In summary, fy(a,b) is the slope of the tangent line to the surface defined by f(x, y) at the point (a, b) in the y-direction.

The given expression represents the partial derivative of f(x, y) with respect to y, evaluated at (a, b):

fy(a,b) = lim┬(y→b)⁡〖[f(a,y) - f(a,b)]/(y - b)〗

Geometrically, this partial derivative represents the slope of the tangent line to the surface defined by f(x, y) at the point (a, b) in the y-direction.

To see why this is the case, consider the following argument:

Let L be the limit in the expression given above.

Let h = y - b be the change in the y-coordinate from b to y.

Then, we can rewrite the limit as:

fy(a,b) = lim┬(h→0)⁡〖[f(a,b + h) - f(a,b)]/h〗

This expression represents the average rate of change of f(x, y) with respect to y over the interval [b, b + h].

As h approaches 0, this average rate of change approaches the instantaneous rate of change, which is the slope of the tangent line to the surface defined by f(x, y) at the point (a, b) in the y-direction.

Therefore, fy(a,b) is the partial derivative of f(x, y) with respect to y, evaluated at (a, b).

This problem is just try and error.

First we try number 2.5 since its the average of all the answers.

2.5^2=6.25

This is smaller than 7 so the answer is either 2.6 or 2.8

Now let's try 2.7

2.7^2=7.29

Which is bigger than 7 and that means the correct answer is 2.6 :)

Answer:

a = 28, b = 12, c = 9

Step-by-step explanation:

The ratio of corresponding sides between the triangles is 4 to 7, or 4/7 (comparing small triangle to the large one).

Set up proportions.

\(\frac{16}{a}=\frac{4}{7}\\\\4a=112\\\\a=28\)

Next, find b.

\(\frac{b}{21}=\frac{4}{7}\\\\7b=84\\\\b=12\)

Finally,

\(c=21-b=21-12=9\)

Answer:

bro all equilateral triangle are equal

Step-by-step explanation:

In geometry, an equilateral triangle is a triangle that has all its sides equal in length. Since the three sides are equal therefore the three angles, opposite to the equal sides, are equal in measure. Therefore, it is also called an equiangular triangle, where each angle measure 60 degrees.

Answer:

1. True

2. False

3. False

4. True

Sep-by-step explanation:

Similarity:

 Two polygons of the same number of sides are similar if

  (i) their corresponding angles are equal and

(ii) their corresponding sides are in the same ratio.

  AAA similarity ,  SAS similarity , SSS similarity

1. True.

  Two polygons of the same number of sides are similar if their corresponding angles are equal. AAA similarity.

In an equilateral triangle each angle is 60°. So, all equilateral triangles are similar.

2. False.

 In each isosceles triangle, the  measurement of angles differs and so the shape wont be same.

3. False.

  In each right angle triangles, the other two angles differs and so, all right triangles will not have the same shape.

4. True.

   All circles have same shape and the only the size of the circle vary. So, all circles are similar.

Step-by-step explanation:

To find how much money each person should get according to the ratio given, we need to divide the total amount of money by the sum of the ratio.

2 + 3 + 5 = 10

Now divide 360 by 10.

360 ÷ 10 = 36

Multiply the 36 to each ratio, for example:

Arwa gets 2 × 36; $72

Tasmiyah gets 3 × 36; $108

Nibras gets 5 × 36; $180

Answer:

let the share be 2x 3x and 5x     now we have 2x+3x+5x=$360        or,10x=$360    Therefore, X=$36       Again , share of arwa=2x=2*36=$72               share of tasmiyah=3*36=$108        share of nibras=5*36=$180

Step-by-step explanation:

The measurement closest to the length of XY in units is 11.7 units (option J).

In the given coordinate grid, the length of XY can be determined by calculating the distance between the two points represented by X and Y. By measuring the grid lines, it becomes evident that the closest measurement to the length of XY is 11.7 units, which corresponds to option J.

To understand this further, we can break down the distance calculation using the distance formula, which states that the distance between two points (x1, y1) and (x2, y2) can be found using the equation:

d = √((x2 - x1)^2 + (y2 - y1)^2)

In this case, we are given the length of XY as 7.8 units, 16.0 units, 13.0 units, and 11.7 units as options. By substituting the coordinates of X and Y into the distance formula, it can be determined that the measurement closest to 7.8 units is 11.7 units, which makes option J the correct choice.

The absolute maximum and minimum values of the function f(x, y) = x^2 + y^2 - 2y on the set R = {(x, y): x^2 + y^2 ≤ 9} can be found by analyzing the critical points and the boundary of the region R.

To find the critical points, we take the partial derivatives of f(x, y) with respect to x and y, and set them equal to zero. Solving these equations, we find that the critical point occurs at (0, 1).

Next, we evaluate the function f(x, y) at the boundary of the region R, which is the circle with radius 3 centered at the origin. This means that we need to find the maximum and minimum values of f(x, y) when x^2 + y^2 = 9. By substituting y = 9 - x^2 into the function, we obtain f(x) = x^2 + (9 - x^2) - 2(9 - x^2) = 18 - 3x^2.

Now, we can find the maximum and minimum values of f(x) by considering the critical points, which occur at x = -√2 and x = √2. Evaluating f(x) at these points, we get f(-√2) = 18 - 3(-√2)^2 = 18 - 6 = 12 and f(√2) = 18 - 3(√2)^2 = 18 - 6 = 12.

Therefore, the absolute maximum value of f(x, y) is 12, which occurs at (0, 1), and the absolute minimum value is also 12, which occurs at the points (-√2, 2) and (√2, 2).

Answer: The correct answer is 24.

Step-by-step explanation: 8x3=24. You're welcome!

Step-by-step explanation:

I think we are talking about boys and girls in the art club.

B = number of boys

G = number of girls

a ratio of 1:3 between B and G means that for every boy there are 3 girls in the art club.

that means

G = 3 × B = 3×8 = 24

so, in total there are

8 + 24 = 32

children in the art club.

The degree measure for angle B is 28° and angle D is 62°.

We are given that:

∠ C = 90°

∠ B = ( 2 x + 10 )°

∠ D = ( 5 x + 17 )°

Now, using the angle sum property of a triangle, we get that:

∠B + ∠ C + ∠ D  = 180°

Substituting the values:

2 x + 10 + 90 + 5 x + 17 = 180

7 x + 117 = 180

7 x = 63

x = 63 / 7

x = 9

∠ B = ( 2 x + 10 )

∠ B = 2(9) + 10

∠ B = 18 + 10

∠ B = 28°

∠ D = ( 5 x + 17 )

∠ D = 5 (9) + 17

∠ D = 45 + 17

∠ D = 62°

Therefore, the degree measure for angle B is 28° and angle D is 62°.

Simply divide both numbers by 9.

After solving, the 150 percent of x is 1.5 times of the given number.

In the given question, we have to explain how to calculate 150 percent.

A figure or ratio stated as a fraction of 100 is called a percentage. It is frequently indicated by the percent sign, "%."

To find the 150 percent of any number, we write 150 percent as;

150/100 = 1.5

Now we multiply 1.5 to the given number.

Let he number is x.

So the 150 percent of x is;

=1.5x

So now we can say that the 150 percent of x is 1.5 times of the given number.
