A dog owner observes that from birth to age 14 weeks, the puppy’s weight can be modelled by the equation w=365×(1.23)t , for (0≤

Fantom [35]

Answer and Step-by-step explanation:

(1) Scale factor is a constant value that multiplies another value. For a puppy's weight, scale factor is 1.23.

The percentage growth is

1.23 = 1 + 0.23

Percentage is 0.23 or 23%.

(2) Equation for increase is

$w=365(1.23)^{t}$

When w = 4000g:

$4000=365(1.23)^{t}$

$(1.23)^{t}=\frac{4000}{365}$

$1.23^{t}=10.96$

Using the log law:

$log_{b} (M^{k}) = klog_{b}(M)$

$log(1.23^{t})=log(10.96)$

t.log(1.23) = log(10.96)

0.08990t = log(10.96)

$t=\frac{log10.96}{0.08990}$

t = 11.56

The puppy will weigh 4000 grams in 11 and half weeks or between 11 and 12 weeks.
