If varies inversely as . It is known that = 10 when = 3, find the value of when = 5.

y = 6

Step-by-step explanation:

If x varies inversely proportional as y.

, k is constant of proportionality

or

k = xy

When x = 3 and y = 10

k = 3×10

k = 30

Put x = 5,

So, the value of y is 6 when x is 5.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
