Find the variation constant and an equation of variation where y varies directly as x and y=16 when x=2
Jlenok [28]

Answer:

variation constant = k = 8

equation of variation : y = 8x

Step-by-step explanation:

Any relationship of variation can be written as y = kx

where k is the variation constant.

_______________________________________

Let the equationof relation between y and x be y =kx here as well

given

y = 16 when x = 2

substituting this value in the equation y = kx

16 = k*2

=> k = 16/2 = 8

Thus,

variation constant = k = 8

equation of variation : y = 8x

PolarNik [594]

Answer:

<h2>AB=8.4 inches</h2><h2>AC=13.05 inches</h2>

Solution,

\frac{ab}{bc}   = tan \: 40 \\ ab = bc \times tan \: 40 \\ ab = 10 \times 0.84 \\ ab = 8.4 \: inches \:

\frac{bc}{ac}  = cos \: 40 \\  \frac{bc}{cos \: 40}   = ac \\ ac =  \frac{10}{cos \: 40}  \\ ac = 13.05 \: inches

Hope this helps...

Good luck on your assignment..
