Which is a characteristic of centrifugal acceleration
goldfiish [28.3K]

Answer: Centripetal acceleration is the idea that any object moving in a circle will have an acceleration vector pointed towards the center of that circle. Centripetal means towards the center. Even an object moving at a constant speed around a circle won't have a constant velocity.

. Samantha is three times as old as Jason. The sum<br> of their ages is 56 years. How old is each?
8_murik_8 [283]

Step-by-step explanation:

let age of samantha be 3x and age of jason be x.(since samantha is three times as old as jason)

Now,

3x+x=56 (sum of their ages is 56)

or 4x=56

or x=56/4

or x=14

therefore age of samantha=3x=3×14=42

age of jason = x = 14

PLEASE HELP LAW OF COSINES
chubhunter [2.5K]
The Law of Cosine states
cosC=(a^2+b^2-c^2)/2ab

so plugging in the numbers gives us

cosJ=(13^2+19^2-11^2)/2(13*19) = 409/494

We now have cosJ so plug that into your calculator and find arccos (arccos(cos(J)) = J)
arccos(409/494)=34.11
rounding your answer will give you 34°
