Answer:
The second leg of the right triangle is about 9.4.
Answer:
A. Length of a bead necklace compared with the number of identical beads
Step-by-step explanation:
Using identical beads in a necklace means that the length of the necklace will depend on the total number of identical beads in the necklace.
For each bead added, the length of the necklace will increase a given, constant, amount. This is a constant rate of change.
We have that if we assume standard exponential growth, the equation of the population will be:
if we start counting from the moment that the population was 7000. We are given that 7000*
=12000, namely that P(5)=12000 and we need to find
. Since e^(10k)=e^(5k)*e^(5k), and since we can solve for e^(5k) from P(5), we have:
e^(5k)=12000/7000 and we can calculate P(10). P(10)=7000
= 20571 people.
Answer:
Step-by-step explanation:
The radius r can be found from the relationship
The point is in Quadrant II (-, +), so use the inverse cosine function to find the angle.
