A mathematical statement that two expressions are equal is called a(n) ______.
zhannawk [14.2K]

Answer:

an equation

Step-by-step explanation:

A mathematical statement that two expressions are equal is called an equation.

The word "equation" comes from the same root as "equality"...  so is two sides of an expression are of equal values, they form an equation, like A = B.

When both sides of a statement are not equal to each other, that is an inequality, meaning NOT equal, like A > B.

Describe the relationship between compound interest and exponential growth
Gennadij [26K]

Answer:

Relationship between compound interest and exponential growth

C.I = P[(1 + \frac{R}{100})^{n} - 1]

where, P =Principal

R =Rate of interest, n= Duration i.e time interval for which money has been taken, C.I =Compound Interest

Exponential growth = A (1+\frac{K}{100})^s

Where , A=Initial value of population, K= Rate at which population is declining in percentage, s=total time between starting population and final population

Now , If you compare between Exponential growth and compound interest

P→(Replaced by)→A,

R→(Replaced by)→K,

n→(Replaced by)→s,

As C.I is calculated for money, and Exponential word is used for both money as well as increase in population.

So, just replacing keeping the meaning same

C.I = P[(1 + \frac{R}{100})^{n}]  - P

→Compound Interest = Exponential growth - Initial Value(either money or any population considered)
