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

A line passes through the points (2, -4) and (4, 2). What is the equation of this line in slope-intercept form?
Aneli [31]

Answer:

A.

Step-by-step explanation:

Slope = y2-y1/x2-x1

(2,-4) = (x1,y1)

(4,2) = (x2,y2)

Slope = (2+4)/(4-2)

          = 6/2

          = 3

Y=mx+b   [Plugging (4,2) into this]

2 = 3×4 +b

2 = 12 + b

b = -10

Jake used 1/6 of 30 pencils in a pack. How many pencils did jale used?
alexira [117]
30 pencils multiplied by 1/6 is equal to 30/6. Reduce 30/6 to lowest term by dividing 30 by 6. The quotient of 30 and 6 is 5. Therefore, Jake used 1/6 or 5 pencils of the 30 pencils in a pack.
