Answer:
A. 8 units
Step-by-step explanation:
Coordinates of A = (-2, -2)
Coordinates of C = (5, 2)
Use distance formula, to calculate the length of diagonal
.
Let,
(nearest tenth)
Therefore, the closest to the length of diagonal
In ΔBCD, the measure of ∠D=90°, the measure of ∠C=77°, and CD = 41 feet. Find the length of BC to the nearest foot.

What is that $13,455.78? Something? I did this and got $13,122.76. Here's how I did it:
Use this formula
where A is the ending amount, P is the starting amount, n is the number of times it compounds a year, and t is the number of years. We have all we need to set it up:
First divide and add inside the parenthesis:
then multiply the exponents:
raise the value inside the parenthesis to the power of 260:
and finally multiply to get A = $13,122.76

Step-by-step explanation:
The logistic differential equation is as follows:
In this problem, we have that:
, which is the carring capacity of the population, that is, the maximum number of people allowed on the beach.
At 10 A.M., the number of people on the beach is 200 and is increasing at the rate of 400 per hour.
This means that when
. With this, we can find r, that is, the growth rate,
So
So the differential equation is:
