The most basic and common reason to use parentheses, brackets, and braces is to control the order of operations.
<h3>What are parentheses?</h3>
In mathematics, parenthesis is used to arrange numbers in the sequence of operations, clarify numbers, and denote multiplication.
Suppose you have an expression as:-
E = { ( 5-2 )8} 6
In this case, you would calculate 5 minus 2 first (parentheses), then multiply by 8 (brackets), then complete the part inside the curly braces, and finally multiply by 6.
Therefore the most basic and common reason to use parentheses, brackets, and braces is to control the order of operations.

r = continuous growth rate
revenue t years after 2013 = 54.5×10⁹×e^(rt)
74.6×10⁹ = 54.5×10⁹×e^(2r)
e^(2r) = 74.6/54.5
2r = ln(74.6/54.5)
r = ½ln(74.6/54.5) ≅ 0.15697 = 15.697% per year
Hope this helps!
The answer to the following question that you have asked is -2-3b
COMPOUNDED
not simple interest,
compound interest is neat since you earn interest on the interest you earned
ok so what you use is F=Pe^(rt)
F=future or ending amount
P=present amount
e=base of the natural log (some digits are 2.71828182845)
r=rate in decimal
t=time in years
presen amount is 400
rate is 9% or 0.09
time is 3 years
F=400e^(0.09*3)
F=400e^(0.27)
F=523.986
round
F=523.99
Answer:
Step-by-step explanation:
125/x=100/0.35
(125/x)*x=(100/0.35)*x - we multiply both sides of the equation by x
125=285.71428571429*x - we divide both sides of the equation by (285.71428571429) to get x
125/285.71428571429=x
0.4375=x
x=0.4375
now we have:
0.35% of 125=0.4375
