Answer:
Displacement will be 11 revolution and 1.02π radian
Step-by-step explanation:
We have given that initial angular position = 0.45 radian
Angular speed 
Time is given as t = 8.8 sec
So angular displacement in 8.8 sec
As he has already covered 0.45 radian
So total angular displacement = 0.45 + 71.8432 = 72.2932 radian
We know that 1 revolution = 2π = 2×3.14 = 6.28 radian
So 11 revolution = 11×6.28 = 69.08 radian
Left dispalcement = 72.2932 - 69.08 = 3.2132 radian = 1.02π radian
Answer:
Rate of change = change y / change x
Change y = + 1
Change x = + 2
SO the rate of change is 1/2
WHAT IS THE Y VALUE WHEN X IS 9
y = 1 MULTIPLY by 4.5 = 4.5
x = 2 MULTIPLY by 4.5 = 9
Y = 4.5 when x = 9
Change the 12 and 1/2 cm to mm which is 125mm + 25mm = 150mm
It seems it should be the other way... . How soon will the puppy catch up with the kitten.
The way you have it the kitten will never catch the pup. There is already 180m between them so, the distance will only increase because the puppy runs faster than the cat.
If the puppy runs after the cat, will eventually catch up with it and can be calculated. Not the other way around.
If the pup runs after the cat, the distance between them will decrease and the pup will catch the cat.
RT = D kitten
RT = D+180 puppy
20T = D
25T = D + 180
Substitution
25T = 20T +180
5T = 180
T = 36s
