Answer:
y = - 
x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c (m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 6, - 3) and (x₂, y₂ ) = (6, - 7) ← 2 points on the line
m = 
= 
= 
= -
The line crosses the y- axis at (0, - 5 ) ⇒ c = - 5
y = - x - 5 ← equation of line
Answer:
- The number of interest periods for quaterly compounding interests for 4 years is: 16
Explanation:
To calculate compounding interests, you must know the number of times the interest is going to be compounded.
You must know that <em>quarterly</em> means four in a year.
The number of interest periods,n, is equal to the number of interest periods in one year multiplied by the number of years.
- n = number of years × number of periods / year
When the interests are calculated once in a year, the number of interest periods for 1 year is: 1 year × 1 period / year = 1 period.
When the interest are calculated four times in a year, and the number of years is 3, then the number of of interest periods is: 3 years × 4 period / year = 12 periods.
This table,with some examples, may help you more:
Compounding periods per year # years # interest periods
Annual 1 1 1 × 1 = 1
Quarterly 4 1 4 × 1 = 4
Semiannually 2 1 2 × 1 = 2
For this problem:
- Compounding: quarterly
- Number of periods per year: 4
- Number of years: 4
- Number of interest periods: 4 periods/year × 4 year = 16 periods.
Cube A volume = 3^3 = 27 cubic meters
Cube B volume = 6^6 = 216 cubic meters
Cube B has (216 / 27) the volume (or 8 times the volume) of Cube A.
