Given
The coordinates of the points on the path are:
P(20,7), R(-4,-9), O(20, -9), S(-4, -24)
The total length of the path from P to S is:
The distance d between two points can be found using the formula:
The distance between P and R:
The distance between R and O:
The distance between O and S:
In the case of bacteria, we use the continuous growth equation:
Final=Initial×e∧(r×t)
In other words, the final amount is equal to the initial amount times e to the rate times time. In order to find your rate, you would plug in the numbers as follows:
3600=3000×e∧(6r)
Therefore: r=0.03
Next, you would plug in the r value and 13 hours into the equation to solve for the final amount.
F=3000×e∧(13×0.03)=4,453 bactera after 13 hours
Answer:
The coordinates are: (-3,-4).
If AC bisects BD, then BC = CD
That means:
2y - 2 = y + 3
Solve:
y -2 = 3
y = 5
