Population Growth The population of a town of 5000

Nesterboy [21]

Answer:

a) $A=5000{(1.03)}^{t}$

b) 5464 inhabitants.

Step-by-step explanation:

The formula used for compound interest becomes very helpful in this case.

$A=P{(1+r)}^{t}\\\\When:\\A = Final Value\\P = Initial Value\\r = Rate of Change (Decimal)\\t = Time (Years)$

Knowing this, we can easily calculate the value for any year, counting from the original 5000.

From this formula, we can derive a specific one that will serve for any value of <em>t</em>.

$A=5000{(1+0.03)}^{t}\\A=5000{(1.03)}^{t}$

b) Apply the formula:

$A=5000{(1.03)}^{3}\\A=5000(1.092727)\\A=5463.635=5464$

The town will have 5464 inhabitants.

Use the substitution method to answer the system of equations. 5x + 2y = 1 y = -x + 2

frosja888 [35]

Answer:

x = -1

Step-by-step explanation:

5x + 2y = 1 (eqn 1)

y = -x + 2 (can also be written as y = 2 - x)

subbing y = -x +2 in eqn 1,

5x + 2(2-x) = 1

5x + 4 - 2x = 1

3x = 1 - 4

3x = -3

x = -1

Hope this helps, and please mark me brainliest if it does!
