Let's carry this math sentence over to its natural, "shapey" element. We're going to look at each term not as an ordinary number, but as <em>the area of some shape</em>.

x² (read as "x <em>squared"</em>) can be seen as the area of a square with side lengths of x. 2x can similarly be seen as the area of a <em>rectangle </em>with a length of x and a width of 2. (Picture 1)

What's our question actually asking, though? Something about <em>perfect squares</em>. More specifically, we're looking for something to add on that'll <em>make this thing a perfect square</em>. We're trying to find a missing piece we can slot in to make a square, in other words. Problem is, our shapes don't look much like a square if we put them together right now. We need to do a little cutting and gluing first.

First, we're gonna cut the 2x rectangle lengthwise, getting two rectangles with an area of x, a length of 1, and a width of x. Next, we're going to attach them to the x² square, creating this shape that looks, strangely, like a square with a little bit missing from it (picture 2). What we're trying to do is <em>complete this square, </em>to find the area of that little missing chunk.

As it turns out, we have all the information we need for this. Notice that, using the lengths of the x rectangles, we can find that the square's dimensions are 1 x 1, which means that its area is 1 x 1  = 1.

If we tack this new area on to our original expression, we've "completed the square!" We now have a perfect square with side lengths of (x + 1) and an area of (x + 1)² (picture 3).

So, our final expression is x² + 2x + 1, and the missing constant - the area of the "missing square" we had to find to complete our larger one - is 1.

Parallelograms geometry acellus pls help
Mamont248 [21]

Answer:

x = 60

Step-by-step explanation:

Recall: one of the properties of a parallelogram is that consecutive angles are supplementary. This means they add up to given 180°

2x and x are consecutive angles. Therefore:

2x + x = 180

3x = 180

Divide both sides by 3

3x/3 = 180/3

x = 60

In a coin game, you repeatedly toss a biased coin (0.4 for head, 0.6 for tail). Each head represents 3 points and tail represent
Sladkaya [172]

Answer:

See answer in explanation

Step-by-step explanation:

State: current points if stop plus a terminal state, that is, 0,1,2,3,4,5,6,7,DONE

Action: Toss, Stop

2. What is the transition function and the reward function for this MDP?

Transition function:

T(Si , TOSS, Si+3) = 0.4 if i < 3

T(Si , TOSS, DONE) = 0.4 if i ≥ 3

T(Si , TOSS, Si+1) = 0.6 if i < 7

T(Si , TOSS, DONE) = 0.4 if i = 7

T(Si , STOP, DONE) = 1

Reward function:

R(Si , TOSS, ANY ) = 0

R(Si , STOP, DONE) = i

R(DONE, STOP, DONE) = 0

3. What is the optimal policy for this MDP? Please write down the steps to show how

you get the optimal policy.

Optimal policy: Toss for 0,1,2 ; STOP for others.

You should include the steps of value iteration. The value iteration will converge at

iteration 3. Result of iteration 3 is as follow,

V3: 0: 4.5 from Toss; 1: 5.4 from Toss; 2: 5.9 from Toss; 3: 3 from

Stop; 4: 4 from Stop; 5: 5 from Stop; 6: 6
