Answer:
simple interest = $300
compound interest =$102.5
Step-by-step explanation:
Simple interest = P* T* R
P= principal, T= time, R= rate
P= $1000, T= 3, R = 0.1
simple interest = 1000 * 3 *0.1 = $300
compound interest = p[(1 + r)ⁿ - 1]
compound interest = 1000[(1 + 0.05)² - 1]
= 1000[1.1025 - 1]
= 1000 * 0.1025
= $102.5
Answer:
Step-by-step explanation:
We have the following expression:
Here we have to group similar terms, but firstly we have to solve what is inside the second parenthesis according to the rules of algebraic operations (equal signs give as a result a positive sing and different sings gives as a result a negative sing):
This expression can be written as:
Applying common factor :
This is the result
Answer:
A, 10 degrees
Step-by-step explanation:
A 10 degrees because 4×10+5=45
.5^3
=.5*.5*.5
=.25*.5
=.125
