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:
Chris earned $ 43,344 each year
Monthly Chris earns $ 3,612
Step-by-step explanation:
If you earn a fixed amount of money each month, for 2 years and one year you have 12 months, then 2 years equals 24 months.
To know how much you earn each month we divide the total amount earned in the two years between 24 months
I = $ 86,688 / 24
I = $ 3,612
Monthly Chris earns $ 3,612
To calculate what he earned each year we divided $ 86,688 / 2
I = $ 86,688 / 2
I = $ 43,344
Chris earned $ 43,344 each year
Step-by-step explanation:
<h2>
Sum of two complementary angle is 90°</h2><h2 /><h2>
so. </h2><h2>
<R+<S =90°</h2><h2>
12x-3+7x-2=90°</h2><h2>
19x-5=90°</h2><h2>
19x=95°</h2><h2>
X= 5</h2>

<R= 60-3=57°</h2>
By using the given graph:
- When x = -2, the value of the function is f(-2) = 1
- When x = -0.5, the value of the function is f(-0.5) = 0.75
- When x = 0, the value of the function is f(0) = 1.25
- When x = 2.5, the value of the function is f(2.5) = 3
- When x = 6, the value of the function is f(6) = 0

How to use the graph to find the values of the function?</h3>
Suppose that we want to find the value of the graphed function when x = a.
- Then we first need to identify x = a in the horizontal axis.
- Then we move upwards (or downwards) until we meet the curve of the function.
- Now you can move horizontally towards the vertical axis, where you can read the y-value associated to the x-value.
Now we can do these steps for each of the wanted values.
- When x = -2, the value of the function is f(-2) = 1
- When x = -0.5, the value of the function is f(-0.5) = 0.75
- When x = 0, the value of the function is f(0) = 1.25
- When x = 2.5, the value of the function is f(2.5) = 3
- When x = 6, the value of the function is f(6) = 0
