Answer:
Step-by-step explanation:
we know that
The formula to calculate continuously compounded interest is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
e is the mathematical constant number
we have
substitute in the formula above and solve for t
Simplify
apply ln both sides
Remember that
(1, 2)
plug 1 in for x and 2 in for y
2x1=2 is 2=2
Answer:
using the pythagoras theorem the answer is a=3
Step-by-step explanation:
basically in a right angled triangle a² + b² equals c². in this equation c is the number on the hypotenuse (the line opposite the right angle)
and 4 could be a or b it doesnt make a difference so I'll call it b.
because we have c² and b² we work backwards like this:
because 9 is a², we must find the square root to find <em>a</em>
so a equals 3
Answer:

Step-by-step explanation:
Answer:
(2,4)
Step-by-step explanation:
What the formula basically does is calculate the "average" x and y. You probably know how to calculate the average of a set of numbers.
The x coordinates are 1 and 3, their average is 2. You get that by adding them (=4) and dividing by 2. (=2)
The y coordinates are 3 and 5, their average is 4. You get that by adding them (=8) and dividing by 2. (=4)
So, in formula:
