^{2})

a is proportional to 1/c

^{3}

a is 5, when b = 9, t = 2, c = 3

Find a' when b'=25, t'=2, c'=5

**My attempt:**

= (25 root 5/12 root 3) 5

I think my steps are wrong, can someone help me!?

Let's start with this part. This means, that a contains both those factors, so you can write it asa is proportional to square root of (b *t^{2})

a is proportional to 1/c^{3}

[tex]a(b, t, c) = \frac{\sqrt{b t^2}}{c^3} \cdot k[/tex]

The k here is some constant number (the proportionality factor). Note that I have written the left hand side as if it were a function of b, t and c.

Now, you
