Something to get you thinking today

LOL in real time for Amigo Miragedriver:
(1) gives out Red as ten, then
(2) gives Green as two;

(3) 2*2 - 2*Blue = 2, so Blue = 1; finally
(4) 1 + 10*2 = 21

21, is this correct?

Pretty elementary algebra

Let:
x = red balloon
y = green balloon
z = blue balloon

Thus:

3x = 30
x + 2y + 2y = 18
2y - 2z = 2

Solve for x, y, and z

3 equations, 3 variables, so it's solvable.

x = 10
10 + 4y = 18, 4y = 8, y = 2
4 - 2z = 2, 2z = 2, z = 1

Therefore:

z + x * y = 1 + 10 * 2 = 21

Excellent amigos.

Excellent amigos.

maybe not just yet ...:

Pretty elementary algebra

...

here's the challenge:

the most complicated way to solve it LOLOL​

I offer (actually I did it while waiting for a waiter with the check for me) to solve the nonlinear system

function F = Amigo(x)

F(1) = 3*x(1) - 30;
F(2) = x(1) + 4*x(2) - 18;
F(3) = 2*x(2) - 2*x(3) - 2;
F(4) = x(3) + x(1)*x(2) - x(4);

in Matlab, starting from the guess of all zeros:

>> [x,fval,exitflag,output] = fsolve(@Amigo, [0 0 0 0])

Equation solved.

fsolve completed because the vector of function values is near zero
as measured by the default value of the function tolerance, and
the problem appears regular as measured by the gradient.

<stopping criteria details>


x =

10.0000 2.0000 1.0000 21.0000


fval =

1.0e-09 *

0 0 0 -0.1384


exitflag =

output =

getting solution of Today at 5:29 PM as the fourth element (highlighted above) of the vector solving a nonlinear problem F(x) = 0

beat this!
(am leaving the pub now)

That just proves my point that the majority of SDF members are smart, engineers or technically oriented.

Some funny signs:

Submarine cars?

Wow Dinosaur crossing.!Don’t people review signs before placing?

Good to know

Where the heck is this?

 

[Miragedriver]

Pegasus Crossing? Which reminds me. Never play leap frog with a Unicorn
