A certain forest covers an area of 2300 km2. Suppose that each year this area decreases by 5.25%. What will the area be after 13

nordsb [41]

Answer:

The area after 13 years will be 1141 km2

Step-by-step explanation:

This problem can be modeled with an exponencial equation:

A = Ao * (1+r)^t

Where A is the Area after t years, Ao is the inicial area and r is the rate that the area changes.

For our problem, we have that Ao = 2300, r = -5,25% = -0.0525 and t = 13.

Then, we can find the area after 13 years:

A = 2300 * (1 - 0.0525)^13

A = 2300 * (0.9475)^13 = 1140.93 km2

Rounding to the nearest square kilometer, we have A = 1141 km2

What would the answer be???

Korolek [52]

Answer:

The solution is obtained by adding the two equations.

The solution is: (x, y) = ( $- \frac{2}{3}$ , $- \frac{7}{3}$ )

Step-by-step explanation:

We are given two equations with two variables. The strategy is to eliminate one variable and solve for both the variables.

The two equations are:

$7x + y = - 7 \hspace{15mm} \hdots (1)$

$2x - y = 1 \hspace{15mm} \hdots (2)$

Adding both the equations, we get:

$7x + 2x + y - y = - 7 + 1$

$\implies 9x = - 6$

$\implies x = - \frac{2}{3}$

Substituting the value of 'x', we get the value of y.

We substitute in (2). [Can be substituted in any equation].

We get: y = 2x - 1

$\imples y = 2\bigg(\frac{-2}{3}\bigg) - 1$

$\implies -\frac{4}{3} - 1$

$\implies y = -\frac{7}{3}$

So, we get the corresponding values of x and y which is the solution of the two equations.
