A certain forest covers an area of 2600 km2. Suppose that each year this area decreases by 7.75%. What will the area be like aft

kakasveta [241]

Answer:

After 15 years, the area will be of 775.3 km²

Step-by-step explanation:

The equation for the area of the forest after t years has the following format.

$A(t) = A(0)(1-r)^{t}$

In which A(0) is the initial area and r is the yearly decrease rate.

A certain forest covers an area of 2600 km2.

This means that $A(0) = 2600$

Suppose that each year this area decreases by 7.75%.

This means that $r = 0.0775$

So

$A(t) = 2600(1-0.0775)^{t}$

$A(t) = 2600(0.9225)^{t}$

What will the area be like after 15 years?

This is $A(15)$

$A(t) = 2600(0.9225)^{t}$

$A(15) = 2600(0.9225)^{15} = 775.3$

After 15 years, the area will be of 775.3 km²

The Thompson family is traveling 1,500 miles to visit relatives. They plan to drive the same distance each day. If the Thompsons

nydimaria [60]

Answer:they will drive 500 miles each day.

Step-by-step explanation:

The Thompson family is traveling 1,500 miles to visit relatives. They plan to drive the same distance each day.

Let x represent the distance that they travel each day. If the Thompsons make the trip in 3 days, it means that the total distance that they travelled in 3 days would be

3 × x = 3x miles

Therefore , the distance that they will drive each day would be

3x = 1500

Dividing both sides of the equation by 3, it becomes

3x/3 = 1500/3

x = 500 miles
