This problem Is an example of geometrica progression. The formula for the sum of geometric progression is:

S = a[(r^n)-1] / (r – 1)

Where s is the sum

a is the first term = 1

r is the common ratio = 2 ( because it doubles every year

n is the number of terms = (19) since the first term is when he was born which he still 0

s = S = 1[(2^19)-1] / (2 – 1)

s = $524,287

Use a truth table to determine whether the following is a tautology, a contradiction, or neither. ~PAP Q~QvQ

NNADVOKAT [17]

Answer:

The statement $\lnot P \land P \rightarrow Q \rightarrow\lnot Q\lor Q$ is a tautology.

Step-by-step explanation:

We have the following statement $\lnot P \land P \rightarrow Q \rightarrow\lnot Q\lor Q$

A truth table shows how the truth or falsity of a compound statement depends on the truth or falsity of the simple statements from which it's constructed.

The simple statements from the statement given are:

$\lnot P$ , $\lnot Q$ , $\lnot P \land P$ , $\lnot P \land P \rightarrow Q$ , and $\lnot Q \lor Q$ with these you can construct the following truth table.

A tautology is a formula that is always true, it is true for every assignment of truth values to its simple components.

The last column contains only true values. Therefore, the statement is a tautology.
