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;

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

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

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

A ride on the roller coaster costs 4 tickets while the boat ride only costs 3 tickets. Michael went on the two rides a total of

True [87]

Let x = roller coaster ticket
let y = boat ride ticket

x + y = 10
4x + 3y = 37

x = 10 - y
4x + 3y = 37
4(10-y) + 3y = 37
40 - 4y + 3y = 37
-y = 37 - 40
-y = -3
y = -3/-1
y = 3

x = 10 - y
x = 10 - 3
x = 7

x = 7 ; y = 3

4x + 3y = 37
4(7) + 3(3) = 37
28 + 9 = 37
37 = 37
