Question 14 (1 point)
The force of gravity on an object varies directly with its mass. The constant of variation due to gravity is 32.2 feet p
Which equation represents F, the force on an object due to gravity according to m, the object's mass?
A)
T = 16 17

Answer 1

13: Since f(1)=10, the sequence must start with 10. We have only one sequence starting with 10, and indeed it verifies f(n+1)=f(n)-2, i.e. the next term is 2 less than the previous one.

14: If y varies directly with x, then there is a constant of variation k such that

`(y)/(x)=k \iff y=kx`

In your case, F varies directly with m, with a constant of variation of 32.2, so we have

`F=32.2m`
