Answer:

y = a[1 + 0.26]^t

Rate = 0.26

This is a growth rate

Explanation:

If we have the following equation modelling a growth or decay.

[tex]y=a[1+r]^t[/tex]

then if r < 0, then the above equation models decay. If a > 0, then the above equation models growth.

We can rewrite our equation y = a(4)¹/6 as

[tex]a(4^{1/6})^t[/tex]

Now

[tex]4^{1/6}=(2^2)^{1/6}=2^{2/6}=2^{1/3}=\sqrt[3]{2}\approx1.26[/tex]

Therefore,

[tex]y=a(\sqrt[6]{4})^t\approx a[1.26]^t[/tex]

which can also be written as

[tex]\boxed{y=a\left[1+0.26\right]^t.}[/tex]

which is our answer!

As can be seen from the above equation, the rate is r = 0.26.

Now r = 0.26 > 0, which means that the equation above models a growth.

Hence, to summerise

y = a[1 + 0.26]^t

Rate = 0.26

This is a growth rate
