Step-by-step explanation:
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.
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
Suppose that each year this area decreases by 7.75%.
This means that
So
What will the area be like after 15 years?
This is
After 15 years, the area will be of 775.3 km²
The carbon dioxide enters the leaves of the plant through small pores called stomata. ... The plant uses sunlight as energy to perform this chemical reaction. Photosynthesis separates carbon dioxide and water — known as CO2 and H2O, respectively — into their individual molecules and combines them into new products.
Add 3x to both sides.
12=-3x
Then divide by -3 on both sides.
X=-4
Let, first term be a and common ratio is r.
So,
Sum of series,
a = 500( 1 - r )
Therefore, the value of common ratio is 0.916 .
Hence, this is the required solution.
