For this case we have that by definition, the area of a triangle is given by:
Where:
b: It is the base of the triangle
h: It is the height of the triangle
According to the data of the statement we have:
Substituting in the formula we have:
So, the area of the triangle is
Answer:
Answers:
a) See the table below
b) The equation is
c) $40,024.02
d) See the graph below
=========================================================
Explanations:
a)
Start with part (b) where I detail how to get the equation.
Once the equation is found, plug in x = 0 to get
Repeat for x = 1
Repeat for x = 2, x = 3, x = 4 and x = 20 to get the table shown below.
-----------------------
b)
The template for any exponential equation is
a = starting amount = 32000
b = growth factor
The annual interest rate is 4.5%
We compound quarterly, so the quarterly rate is (4.5%)/4 = 1.125% which converts to the decimal form 0.01125; adding one to this leads to the growth factor of b = 1.01125
We go from to
-----------------------
c)
Plug in x = 20 to represent 20 quarters have elapsed (aka 20/4 = 5 years)
The investment would be worth $40,024.02 after five years, aka twenty quarters.
-----------------------
d)
See below for the graph. I'm using GeoGebra to make the graph. Another option is Desmos. It's preferable to use technology than to graph by hand. If you wanted to graph by hand, then you'd plot each of the points found in the table. Then draw a curve through all those points.
