Y ∝ 1 √ x If y = 4 when x = 64 find, y when x = 16

Given:

y = 4 when x = 64

To find:

The value of y when x=16.

Solution:

We have,

          ...(i)

Where, k is the constant of proportionality.

We have, y = 4 when x = 64.

Putting k=32 in (i), we get

Putting x=16, we get

Therefore, the value of y is 8 when x=16.

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
