. Anne is pushing a wheelbarrow filled with mulch to place in her garden. She is pushing the wheelbarrow with a force of 70 N at

Kruka [31]

<u>Answer:</u>

When Anne pushes the wheelbarrow 25 meters the work done is 1120 joules

<u>Solution:</u>

We know $\text { Work }(\mathrm{W})=\text { Force }(\mathrm{F})\times\text { Distance (D) }$

Anne is pushing the wheelbarrow with a force of 70 N at an angle of $50^{\circ}$ with the horizontal

So the force of Anne will be $F=70 \cos 50^{\circ}=(70 \times 0.64)=44.8 \mathrm{N}$

She pushes the wheelbarrow 25 meter, So D = 25 meters

So, the $work,F\times D=(44.8 \times 25)=1120 \text { Joules }$

Anne has done total 1120 joules work.

What is the vaule of the x

Amiraneli [1.4K]

D. X=3cm
Since the triangles are similar, just set up a proportion to solve for x.

4/8=x/6. Then just cross multiply and solve from there.

Factor by grouping m(2a+b)-n(2a+b)+2n(2a+b)

lys-0071 [83]

The factored expression of m(2a+b)-n(2a+b)+2n(2a+b) is (m + n)(2a + b)

<h3>How to factor the expression?</h3>

The expression is given as:

m(2a+b)-n(2a+b)+2n(2a+b)

Factor out 2a + b

m(2a+b)-n(2a+b)+2n(2a+b) = (m - n + 2n)(2a + b)

Evaluate the like terms

m(2a+b)-n(2a+b)+2n(2a+b) = (m + n)(2a + b)

Hence, the factored expression of m(2a+b)-n(2a+b)+2n(2a+b) is (m + n)(2a + b)

A Markov chain has 3 possible states: A, B, and C. Every hour, it makes a transition to a different state. From state A, transit

Sedaia [141]

Answer:

A) distribution of x2 = ( 0.4167 0.25 0.3333 )

B) steady state distribution = $\pi a \frac{4}{9} , \pi b \frac{2}{9} , \pi c \frac{3}{9}$

Step-by-step explanation:

Hello attached is the detailed solution for problems A and B

A) distribution states for A ,B, C:

Po = ( 1/3, 1/3, 1/3 ) we have to find the distribution of x2 as attached below

after solving the distribution

x 2 = ( 0.4167, 0.25, 0.3333 )

B ) finding the steady state distribution solving

$\pi p = \pi$

below is the detailed solution and answers
