a spray can is usedto paint a wall .the thickness of the paint on the wall is t. the distance of the spray can from the wall is d. t is inversly proportional to the square of d. t=0.2 when d=8.find t when d=10

t = 0.128

Step-by-step explanation:

Proportionality

We are given the following proportionality rule: t is inversely proportional to the square of d. This can be written as:

Where k is the constant of proportionality. It can be found by using the condition: t=0.2 when d=8. Substituting:

Solving for k:

k=12.8

The equation is:

When d=10:

t = 0.128

28

step-by-step explanation:

because that's the answer
