28.28 ft , 44 fr

Step-by-step explanation:

Circumference of 1st circle = \piD = 22/7 ×9 = 198/7 = 28.28 ft

Circumference of 2nd circle = \piD = 22/7 × 14 = 44 ft

Answer:

Step-by-step explanation:

Yellow Circle:

9+2.5 = 11

2 x pi x 11= 69.115

Nearest hundredth = 69.12

Purple Circle:

9 divided by 2 = 4.5

2 x pi x 4.5 = 25.1327

Nearest hundredth = 25.13

An object in a simulation accelerates
notsponge [240]

Observe the graph below. This graph represents the scenario.

The question is ill formated, the complete question is

In a simulation, a moving object accelerates from rest to 4 meters per second in 2 seconds. For the following three seconds, it increases linearly until it reaches a speed of 10 meters per second. Following three seconds at that speed (acceleration = 0), the item progressively decelerates until it comes to rest two seconds later. Draw the graph of this scenario for 10 seconds?

I'll describe how the graph may show.

It will move diagonally upward from time 0 to 2 seconds until it reaches the y axis at a speed of 4 m/s.

Then, from 2 to 5, the position will move up diagonally until it reaches the y axis at a speed of 10 m/s.

The next 5 to 8 seconds will be horizontal.

After that, it will descend diagonally.

Observe the graph below. This graph represents the scenario.
