2. All squares are parallelograms.
3. All trapezoids are scalene.
4. All squares are rhombuses.
5. All rhombuses are squares.
6. All rectangles are squares.
7. All squares are rectangles.
The truthfulness of these "geometric" statements varies; while all squares are parallelograms, rectangles, and rhombuses, the opposite is not true for all these shapes. The other statements are also false, as trapezoids don't need to be scalene and not all rectangles are squares.
The answers to these questions are dependent on the definitions of geometric shapes. Let's look at these one by one:

The amount will be $4499.45 if an investment account earns 4% per year compounded annually if the initial investment was $4000.
It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:
Where A = Final amount
P = Principal amount
r = annual rate of interest
n = how many times interest is compounded per year
t = How long the money is deposited or borrowed (in years)
It is given that:
An investment account earns 4% per year compounded annually if the initial investment was $4000.
P = 4000
r = 4% = 0.04
t = 3
n = 1
Plug all the values in the formula, and we get:
A = 4000(1 + 0.04)³
A = $4499.45
Thus, the amount will be $4499.45 if an investment account earns 4% per year compounded annually if the initial investment was $4000.
