Two.
b1 = - 4 + sqrt(19), b2 = - 4 - sqrt(19)
Answer:
Option A
Step-by-step explanation:
Positive correlation describes a relationship between two variables where both variables move in the same direction. In this case, the response variable will increase as the explanatory variable increases.
You will need to use this formula:
<span>Years = {log(total) -log(Principal)} ÷ log(1 + rate)
Years = [log(15,000) - log(2,500)] / log (1.0525)

Supplementary angles are made when two angles equal a sum of 180 degrees. Some real life examples of supplementary angles are stars, cups and logos.
Answer:
120°
Step-by-step explanation:
Sum of angles = (n-2)180°, where n is the number of sides.
This is a hexagon, so n=6.
Sum of angles = (6-2)180° = 720°
Each interior angle = 720°/6 = 120°
