If y varies inversely a X², how dose x varies with y​

Mathematics
1 answer:
Rufina [12.5K]3 years ago
4 0

Step-by-step explanation:

square of x is x2

Inverse of square of x is 1 / x2

So the equation would be:

y = k / x2

where k is a proportionality constant.

To find the value of k, plug in the known values for x and y: x=3, y=45

45 = k / 32 = k / 9

k=405

Now you have the full equation with proportionality factor.

y = 405 / x2

then, for x=5:

y = 405 / 52 = 405 / 25

y = 16.2

Tanya walked for 171717 minutes from her home to a friend that lives 1.51.51, point, 5 kilometers away. d(t)d(t)d, left parenthe
Butoxors [25]

Correct question is;

Tanya walked for 17 minutes from her home to a friend that lives 1.5 kilometers away. D(t) models Tanyas remaining distance to walk in kilometers, t minutes since she left home. What number type is more appropriate for the domain of d?

Answer:

0 ≤ t ≤ 17 ; (0, 17)

Step-by-step explanation:

We are told that she has walked for 17 minutes from her home to a friend that lives 1.5 kilometers away.

Now, we want to find the domain of numbers that shows her remaining distance.

Since she spent 17 minutes, then it means in modeling remaining distance it could be from 0 to 17 minutes as the case may be. Thus, the domain can be written as;

0 ≤ t ≤ 17 ; (0, 17)
