Answer:
Step-by-step explanation:
-We can use the exponential decay function to estimate the size after 13 years:
Where:
is the size after t years, t is the time, r is the rate of decay and
the original size.
#We substitute and calculate as:
Hence, the forest covers after 13 years.
Answer: The measure of the other acute angle is 52.8°
Step-by-step explanation:
Hi, since the situation described forms a right triangle ( see attachment) , we know that the three interior angles of a right triangle add up to 180 degrees.
The value of one angle is given = 37.2°.
Since is a right angle it has also a right angle of 90°.
So we can write an equation:
x + 37.2 + 90 = 180
Where x is the measure of the other acute angle.
Solving for x:
x = 180-90-37.2
x = 52.8°
