P v Q is a disjunction, which is true whenever P or Q is true or both are true. P v Q is false only when P and Q are both false.
You know that Q is false, because 3 is not the square root of 10, so the only possibility for P v Q be true is that P is true.
If that is the case, you have this relation:
T F ---> T
which means True and False imply True

The answer is the number 2
Answer:
Step-by-step explanation:
Denote first four terms of the geometrc sequence as
Note that
Then the common ratio is
Therefore, the recursive formula for the geometric sequence is
Estimation is the process of making quick mental calculation of a value, quantity, or number.
We basically do estimation every day of our lives.
For example, we want to order several pizzas. We know that each pizza costs between $5 to $10. We order 3 pizza pies; Pie 1 = $6; Pie 2 = $8; Pie 3 = $9.
In getting an estimate, we either overestimate or underestimate. We know that whether a product of an estimate is overestimated or underestimated by the direction of the rounded up numbers.
We overestimate, when we round up the numbers
We underestimate, when we round down the numbers.
Overestimate: $10 x 3 pizza = $30 total cost
Underestimate: $5 x 3 pizza = $15 total cost
Actual cost: $6 + $8 + $9 = $23
In estimating expenses, it is better to overestimate. This gives us an allowance when incidental expenses incur.
In estimating income, it is better to underestimate. It gives us a more realistic value of the income.
