Let be "x" the height in inches of a stack of
pennies.
You know that the thickness of 1 pennie is
, then, you can write the following proportion:

Solve for "x":

To express this height in Scientific notation the decimal point must be after the first digit, so you must move it one place to the left:

Answer:
100
Step-by-step explanation:
discriminant = b^2 - 4ac
here
b = 6, a= 4, c = -4
6^2 -4 •4•-4 = 36 +64 = 100
Answer:
The approximate value of the investment in one year is 4183.
Step-by-step explanation:
The formula for finding the compound interest for one year that compounded quarterly is :

Here,
P - Principal = 4000
r - 4.5%
t - 1
