Answer:
It is important because they are the basics of algebra. Almost every algebraic problem you will ever solve is based on these fundamental properties. In equations, we almost never know every part of it so we will need variables to substitute the unknown amount in an equation. Variables are used for basically every equation/problem in algebra. Inequalities are not as important as variables but are still really important. Inequalities are basically comparing numbers. And in algebra when they add variables into an inequality, the inequality will help lower the number of possible values of said variable. And exponents are just a basic operation in algebra. Just like learning addition and subtraction. It is like a quicker and less complicated way of multiplying numbers.
Answer:
285541
Step-by-step explanation:
According To The Question,
- Given, A culture of bacteria has an initial population of 41000 bacteria and doubles in every 5 hours &
.
Now, for the population of bacteria in the culture after 14 hours is 
. We have Initial Population(
)=41000 , d=14 & t=5 .
Put These Value in Above Formula, We get
285540.5847 ≈ 285541

Answer:
Step-by-step explanation:
You need the Law of Cosines for this, namely:
where x is the missing side.
and
so
x = 18.0 or just 18
