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

George was reading a mystery story. He read 42 pages in one hour. At this rate how many pages can he read in 40 minutes?
Viefleur [7K]

Answer:

56.8

Step-by-step explanation:

Ratios.

42------60

1----------1.42

40-------56.8

First, divide 42 by 42 which is one. Then, divide 60 by 42, which is 1.42.

Next, multiply 1 by 40. Finally multiply 1.42 by 40 which is 56.8. Hope this helps
