If y varies inversely a X², how dose x varies with y​
Rufina [12.5K]

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

Math problem!!! Help needed 10 points !!!
My name is Ann [436]

ANSWER

Option D

EXPLANATION

The parent radical function is

f(x) =  \sqrt{x}

The transformed function is

g(x) = 2 \sqrt{x - 3}

This is a transformation of the form.

y = a \sqrt{x - k}

which shifts the parent function horizontally by k units to the right and stretches the parent function vertically by a factor of 'a'.

In this case a=2 and k=3,

there is a horizontal shift of 3 units to the right and a vertical stretch by a factor of 2.

The last choice is correct.
