Answer:

The Area of a circle is

$\pi {r}^{2}$

Therefore the Area of Circle A is

$\pi {8}^{2} \\ 201.06$

Area of Circle B is

$\pi {10}^{2} \\ 314.16$

Circle C

$\pi {14}^{2} \\ 615.75$

Identify the domain and range of y = 4x - 5 + 3

Zepler [3.9K]

Answer:

$\huge\boxed{\text{Domain:}\ D=\mathbb{R}=(-\infty;\ \infty)}\\\boxed{\text{Range:}\ R=\mathbb{R}=(-\infty;\ \infty)}$

Step-by-step explanation:

y = 4x - 5 + 3 = 4x - 2

It's an equation of a line in the slope-intercept form.

y = 4x - 2 → f(x) = 4x - 2 - it's a lienar function.

The domain of a linear function is the set of all real numbers.

If a slope of linear function is different than 0, then the range is the set of all real numbers.

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
