Sagot :

Answer:

1. A varies directly

as b

and inversely

A = Kb/c

2. W varies jointly as c and the square of x and inversely as y. W = kcx^2

y

3. P varies directly as the square of x and inversely as s. P = kx^2

s

4. The acceleration A of a moving object varies directly as the

distance d it travels and inversely as the square of the time t it travels. A = kd

t^2

5. The pressure P of a gas varies directly as its temperature tand

inversely as its volume V. P = kt

V
