Answer:
How to calculate interest rate
Step 1: To calculate your interest rate, you need to know the interest formula I/Pt = r to get your rate. ...
I = Interest amount paid in a specific time period (month, year etc.)
P = Principle amount (the money before interest)
t = Time period involved.
r = Interest rate in decimal.
<span>A sphere is a perfectly round geometrical object that is three dimensional, with every point on its surface equidistant from its center. Many commonly-used objects such as balls or globes are spheres. If you want to calculate the volume of a sphere, you just have to find its radius and plug it into a simple formula, V = ⁴⁄₃πr³</span>
Answer:
A. The coefficients of the sum are whole numbers and the sum is a polynomial.
Step-by-step explanation:
The approach to demonstrate the closure property for the sum consists in defining what a polynomial is and demonstrate that the sum of two polynomials with integer coefficients is equal to a polynomial with integer coefficients. We proceed to show the proof below:
1) 
, 
Given
2) 
Definition of addition
3) ![(5\cdot m +2\cdot m ) +[(-3)+4]](https://tex.z-dn.net/?f=%285%5Ccdot%20m%20%2B2%5Ccdot%20m%20%29%20%2B%5B%28-3%29%2B4%5D)
Definition of substraction/Associative and Commutative properties
4) 
Distributive property/Definition of substraction
5) 
Definition of addition/Result
Hence, the coefficients of the sum are whole numbers and the sum is a polynomial. The correct answer is A.
Answer:
B.
Step-by-step explanation:
We see (-10) repeating six times. This means the product would be 6(-10). To simplify this, 6 × (-10) = -60.
