Answer:
A = P x r^t
Step-by-step explanation:
A = Amount (e.g. number of organisms in population after certain period of time)
P = Principal/ Initial Value (e.g. the starting population)
r = rate as a decimal (e.g. if a population increases over certain period of time by 20%, r would equal 1.2)
t = time in whichever units you need.
Example of problem using formula:
A population of 2000 decreases by 20% every year, find the population size after 5 years.
A = ?
P = 2000
r = 0.8
t = 5
A = Pxr^t
A = 2000 x 0.8^5
A = 655.36

Answer:
0.032
Step-by-step explanation:
Answer:
14 and 21 and 28
Step-by-step explanation:
2:3:4.
The shortest side is 14
14/2 = 7
Multiply each side by 7
2*7:3*7:4*7
14 : 21 : 28
Answer:
12/13 so option A
The way you know is because the cosine is adjacent over hypotenuse so for angle U that would be 12/13
This is how you solve this equation:
y^2-1=48 (add 1 to both sides)
y^2=49 (square root both sides)
y=7 y=-7 (because when you square root, the answer is positive and negative)
