Answer to Problem 6WE

The value of v is ±4 .

Explanation of Solution

Given information:

The value of, v , where r=4.5,a=10 .

If a varies directly as r and inversely as square of v . If a=15 when r=27 and v=8 .

Calculation:

Consider the value of, v , where r=4.5,a=10 .

If a varies directly as r and inversely as square of v . If a=15 when r=27 and v=8 .

As y varies directly as x , then the variation is direct and its equation is in the form y=kx .

When it varies inversely as x , then the variation in inverse and its equation is in the form of

  y=kx

Where k is the constant of variation.

Recall that the a ,varies inversely as the square of v and directly as r, then:

  a=krv2

Here , If r=27 when v=8 and the value of a=15 .

  a=krv215=k278215=27k6415×54=27k

From here the value of k is:

  15×54=27k960=27k96027=k3209=k

Thus the equation of the variation is :

  a=krv2a=3209rv2a=320r90v2

Now to find the value of v when r=4.5 and a=10 .

Now apply these values in the above expression:

  a=320r90v210=320×4.59v210=14409v210×9v2=1440

Then the value of h is:

  10×9v2=144090v2=1440v2=144090v2=16

That is:

  v2=16v=±16v=±4

Thus, the value of v is ±4 .
