The perimeter of the semicircle is 25.71 cm. Calculate the value of radius x. Take pi to be 3.142

yan [13]

Answer:

5 cm

Step-by-step explanation:

$Perimeter of semicircle = \frac{1}{2} \times 2\pi \: x +2x\\ 25.71 = 3.14 2\times x+ 2x\\ 25.71 = 5.14 2 x\\ x = \frac{25.71}{5.142} \\ x = 5 \: cm$

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

A right rectangle prism has a length of 5 cm a width of 4 cm and a height of 3 cm the dimensions of the prism are doubled what i

IRISSAK [1]

Answer: 376 cm^2

Step-by-step explanation:

First you would double all the dimensions:

l = 5 cm x 2 = 10 cm

w = 4 cm x 2 = 8 cm

h = 3 cm x 2 = 6 cm

The formula for finding the surface area of a rectangular prism is A=2(wl+hl+hw)

Substitute the values:

A=2(8*10+6*10+6*8)

Solve using PEMDAS:

A=2(80+60+48)

A=2(188)

A=376

Surface area is always in units^2:

376 cm^2

Which algebraic representation shows a reduction?

Grace [21]

Answer:

D. (x, y) → $(\frac{1}{2}x,\frac{1}{2}y)$

Step-by-step explanation:

A dilation is a transformation which reproduces an image of the same shape as the original, but might be of a different size.

When the dilation produces a smaller image is called a reduction.

Mathematically, a reduction occurs whenever the scale factor is between 0 and 1.

Out of the options, the only one that has a scale factor less than one is:

(x, y) → $(\frac{1}{2}x,\frac{1}{2}y)$

Since the scale factor is 1/2 which is less than 1.

All other options are not reductions.
