Answer:

<h2>3</h2>

Step-by-step explanation:

Breadth-First Search is an algorithm to search in a data structure. It starts at the tree root and explores all the neighbor nodes.

Applying this algorithm, you would find that the minimum number of edges that it would require to reach vertex H from vertex A is 3.

We start at vertex A and explore each neighbor node which are B, C and D. If you go through vertex B, you would pass through 4 vertecis to get to H, if you go through C, there would be also 4 vertices. However, if you go through D, you would pass through only 3 vertices.

Therefore, the answer is 3.

A bicycle with 18-in.-diameter wheels has its gears set so that the chain has a 6-in. radius on the front sprocket and 3-in. rad
Airida [17]

Answer:

<h2>19.28 mph</h2>

Step-by-step explanation:

<em>"The question is not complete, here is the complete question</em>

<em>A bicycle with 18-in.-diameter wheels has its gears set so that the chain has a 6-in. radius on the front sprocket and 3-in. radius on the rear sprocket. The cyclist pedals at 180 rpm.</em>

<em>Find the linear speed of the bicycle in in/min (correct to at least two decimal places)  </em>

<em>How fast is the bike moving in mph (to two decimal places)?"</em>

Step one:

given data

the diameter of wheels= 18 inches

radius of front sprocket=6 inches

radius of rear sprocket= 3 inches

The cyclist pedals at 180 rpm

The chains move at the same speed, hence

the rear sprocket must make 6/3 revolutions for every one revolution made by the front sprocket

when the rider moves the front sprocket through 180 revs/min

the rear sprocket moves through 180 (6/3)  = 360 revs/min

the linear speed of the bicycle in inches per minute  =

 2π * 9 * 360   = about 20360.16  in/min

<u>The speed in mph</u>

=2π * 9 * 360 * 60 minutes in 1 hr /63360 in/ mile  

=19.28 mph

stellarik [79]

Answer:

-19

Step-by-step explanation:

1) substitute a with 2 and b with 5

(3 + 2)^2 * (4-5) + √36

2) solve the brackets and the square root

(5^2) * (-1) + 6

3) solve the power

25 *(-1) + 6

4) solve the multiplication

-25 + 6

5) solve the sum
