A coin is dropped at random on the grid. Then another coin is dropped on the grid. What is the probability that both coins fall
Vaselesa [24]
In the picture, we could see that the grid's dimension is 6 by 6. Therefore, there were 6 times 6 equal 36 squares where the coin can be dropped. Solving for the probability that coin will fall in the shaded region, we have:
Probability = 8/36
Probability = 2 / 9

The answer is the letter "a" which is 2/9.

Find the critical points of the surface f(x, y) = x3 - 6xy + y3 and determine their nature.​
Vedmedyk [2.9K]

Compute the gradient of f.

\nabla f(x,y) = \left\langle 3x^2 - 6y, -6x + 3y^2\right\rangle

Set this equal to the zero vector and solve for the critical points.

3x^2-6y = 0 \implies x^2 = 2y

-6x+3y^2=0 \implies y^2 = 2x \implies y = \pm\sqrt{2x}

\implies x^2 = \pm2\sqrt{2x}

\implies x^4 = 8x

\implies x^4 - 8x = 0

\implies x (x-2) (x^2 + 2x + 4) = 0

\implies x = 0 \text{ or } x-2 = 0 \text{ or } x^2 + 2x + 4 = 0

\implies x = 0 \text{ or } x = 2 \text{ or } (x+1)^2 + 3 = 0

The last case has no real solution, so we can ignore it.

Now,

x=0 \implies 0^2 = 2y \implies y=0

x=2 \implies 2^2 = 2y \implies y=2

so we have two critical points (0, 0) and (2, 2).

Compute the Hessian matrix (i.e. Jacobian of the gradient).

H(x,y) = \begin{bmatrix} 6x & -6 \\ -6 & 6y \end{bmatrix}

Check the sign of the determinant of the Hessian at each of the critical points.

\det H(0,0) = \begin{vmatrix} 0 & -6 \\ -6 & 0 \end{vmatrix} = -36 < 0

which indicates a saddle point at (0, 0);

\det H(2,2) = \begin{vmatrix} 12 & -6 \\ -6 & 12 \end{vmatrix} = 108 > 0

We also have f_{xx}(2,2) = 12 > 0, which together indicate a local minimum at (2, 2).

I don't know how to do this can someone please help me?
kotykmax [81]

Given - diameter = 98 cm

So radius = 98/2

=> radius = 49 cm

Area of circle = πr^2

=> Area of circle = 22/7 * 49 * 49

=> Area of circle = 7,546 cm^2

The drawing of a building, shown below, has a scale of 2 inches to 8.5 feet.
sashaice [31]

Answer:

36 1/8 feet

Step-by-step explanation:

x = height of house in feet

2"/8.5' = 8/5"/x

cross-multiply:

2x = 72.25

x = 36.125 or 36 1/8
