The value of x varies directly with y, and when x= 1/3,y = 12. Write an equation to represent the direct variation. Enter the equation with no spaces. If "k" is a fraction, reduce the fraction to simplest form and enter it without spaces.
Equation:

Equation:

Step-by-step explanation:

The equation that represents a direct variation between variable x and variable y is given as . Where, k is the constant of proportionality.

Find the value of k given that x = ⅓ and y = 12.

Plug the values into the equation.

Multiply both sides by 3

Substitute the value of k into

Equation:

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.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
