Alex

Answer:

R = 6S/T

Step-by-step explanation:

R ∝ S/ T

》R = kS/ T

》k = RT/ S

If R = 8 when S = 4 and T = 3

then, k = (8 × 3)/ 4

k = 6

∴ R = (6 × S)/ T

Given a unit circle, what is the<br> value for y?<br> (1/3, y)<br> y = ?

BigorU [14]

Answer:

$y=+\frac{2\sqrt{2} }{3}\\$

Step-by-step explanation:

<h2>In the unit circle we have:</h2><h2> $x^{2} +y^{2} =1$ </h2>

In the picture we see that x=1/3.

<h2>Using de equation of unit circle:</h2>

$(\frac{1}{3} )^{2} +y^{2} =1\\\\\frac{1+9y^{2} }{9}=\frac{9}{9} \\\\y^{2} =\frac{8}{9} \\\\\sqrt{y^{2}} =\sqrt{\frac{8}{9}}\\\\y=+\frac{2\sqrt{2} }{3}$

y is positive because y are in the first quadrant of the cartesian plane.
