You are moving the robot to your classroom, which measures 30 feet by 40 feet.
AlladinOne [14]

Answer:

1) See figure attached

2)

a) d = \sqrt{(x_2 -x_1)^2 +(y_2 -y_1)^2}

And if we replace we got:

d = \sqrt{(10 -6)^2 +(15 -9)^2}= 7.211

b) V = \frac{d}{t}

And if we replace we got:

V = \frac{7.211 ft}{2 sec}=3.606 s

Step-by-step explanation:

Part 1

We can see the plot in the figure attached.

Part 2

a)

For this case we have two points (x_1 , y_1) = (6,9) , (x_2 , y_2) = (10,15)

And we want to find the distance travelled between these two points and we can use the following formula from the euclidian distance between two points:

d = \sqrt{(x_2 -x_1)^2 +(y_2 -y_1)^2}

And if we replace we got:

d = \sqrt{(10 -6)^2 +(15 -9)^2}= 7.211

b)

Since it takes two seconds in order to go from (6.9) to (10,15) we can use the definition of velocity:

V = \frac{d}{t}

And if we replace we got:

V = \frac{7.211 ft}{2 sec}=3.606 s

Tran is solving the quadratic equation 2x2 – 4x – 3 = 0 by completing the square. His first four steps are shown in the table.
Nady [450]
The following steps of solving for the roots of 2x² - 4x -3 = 0 were retrieved from another source Step 1 2x² - 4x = 3 Step 2 2(x² - 2x) = 3 Step 3 2(x² - 2x + 1) = 3 + 1 Step 4 2(x - 1)² = 4 From this, we can see that on Step 3, Tran made a mistake of adding 1 to 3. As we can see, 2(x² - 2x + 1) = 2x² - 4x + 2. That means, instead of adding 1, it should have been 2. Therefore, the step that Tran first made an error is Step 3<span>.</span>

A poll was conducted in states A, B, and C to determine which candidate voters would most likely vote for. The results are displ
max2010maxim [7]
<span>P(liberal | State A) means that probability of liberal candidates to be voted for within state A. This probability could be calculated by the pattern: number of successful events/total events. The successful events referred here is the number of liberal votes in state A. That is equal to 22. The total events is the total number of votes in state A which is 40. 

Thus, the probability is 22/40 = 0.55</span>
