Hi my lovely people! Today's question is math!
There are 2 screenshots below of my work!
(P. S its due today so yeah i will give brainlist too!)

Part 1:

A - (4,9)

B - (6,3)

C - (1,3)

D - (8,7)

E - (8,9)

 To know where to put the dots on the graph, use the coordinates you've just been given:

Example: (4,8)

Move to the 4 on the x-axis (the line on the bottom going horizontal)

Then, move up 8 units (up to the 8 on the y-axis)

Place the point at that spot.

Part 2:

A - (1,2)

B - (2,4)

C - (3,6)

D - (4,8)

 Derek decorates 10 cookies in 5 minutes. We know he took 5 minutes to decorate 10 cookies because in the table, the x-axis is told to us that it represents the time it takes. Since the x coordinate is 5 in the point (5,10) and the y coordinate is 10, we can safely say that it took Derek 5 minutes to decorate 10 cookies.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

the answer is b.

64

step-by-step explanation:

c=2πr=2·π·8≈64
