Given an initial quantity Q0=150 and a growth rate of 7% per unit time, give a formula for the quantity Q as a function of time

rodikova [14]

Answer:

Step-by-step explanation:

From the given information:

(a)

Since growth quantity is not continuous

$Q(t) = 150 (1.07)^t$

For t = 10

$Q(10) = 150 (1.07)^{10}$

$\mathbf{Q(10) = 295.073}$

(b)

Here, for a continuous growth rate, the growth quantity can be computed in terms of initial quantity and the growth rate.

i.e.

$Q(t) = 150 e^{0.07t}$

At t = 10 for a continuous growth rate;

$Q(10) = 150 e^{0.07 \times 10}$

$Q(10) = 150 e^{0.7}$

$\mathbf{Q(10) = 302.063}$
