General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
- Terms/Coefficients/Degrees
- Expand by FOIL (First Outside Inside Last)
<u>Geometry</u>
- Area of a Rectangle: A = lw
Step-by-step explanation:
<u>Step 1: Define</u>
<em>l</em> = x
<em>w</em> = x - 1
<u>Step 2: Find </u><em><u>A</u></em>
- Substitute [AR]: A = x(x - 1)
- Distribute <em>x</em>: A = x² - x
Subtract c^2 from a^2+b^2, on the left.
Next, enclose your result inside parentheses.
Next, place a " - " sign in front of this last expression.
This result is the value of 2abcos C.
Answer:
929,477.13
Step-by-step explanation:
Number of years, n = 20
Using the relation :
a(1- r^n)/ (1 - r) ;
where a is the first term, r is the common ratio and n is the number of years
a = 19000
r = 1 + 8.6% = 1.086
19000(1 - 1. 086^20) / (1 - 1.086)
19000(1 - 1.086^20) / (1 - 1.086)
−79935.0336930 / (1 - 1.086)
= 929,477.13
