Hi there! The answer is 400 square yards.
When the total fencing around a square field is 80 yards, that means that the fencing on one side of the square field is 80 / 4 = 20 yards (Since a square field has 4 sides which are equally as long as every other side).
When the side of the field is 20 yards, the area (which is width * length) equals 20 yards * 20 yards = 400 square yards.
The answer is B
because
16 x 7 =112
The function that models the growth of the population is P = 276.6e^0.009t
<h3>What is the function?</h3>
We can see that the table shows the increase in population over time. We know that population growth is an example of exponential function. We have to apply the formula of exponential function.
Let us now obtain the function that could show the population at each time;
Given that;
Po = initial population
P = population at time t
r = rate of population growth
P = Poe^rt
P = 305.9
r = ?
t = 10
Po = 276.6
Substituting values;
305.9 = 276.6e^10r
305.9/276.6 = e^10r
1.1 = e^10r
ln 1.1 = 10r
r = ln1.1/10
r = 0.009
Thus the function is;
P = 276.6e^0.009t
