Answer:
find the constant rate of proportionality
Step-by-step explanation:
Answer:
Approximately 22.97 years
Step-by-step explanation:
Use the equation for continuously compounded interest, which uses the exponential base "e":

Where P is the principal (initial amount of the deposit - unknown in our case)
A is the accrued value (value accumulated after interest is compounded), in our case it is not a given value but we know that it triples the original deposit (principal) so we write it as: 3 P (three times the principal)
k is the interest rate : 5% which translates into 0.05
and t is the time in the savings account to triple its value (what we need to find)
The formula becomes:

To solve for "t" we divide both sides of the equation by P (notice it cancels P everywhere), and then to solve for the exponent "t" we use the natural logarithm function:



Answer:
B, D and also E
Step-by-step explanation:
When figures are congruent, they have the same shape and size. All measures of one of the figures are identical to the corresponding measures of the other.
Of these statements, the following must be true ...
- B. The corresponding sides of the triangles are congruent
- C. The corresponding angles of the triangles are congruent
- D. The triangles have the same shape and size
