Answer:
The sum of the first 6 terms of the infinite series will be - 21.
Step-by-step explanation:
In this case, the infinite geometric series 1 - 2 + 4 - 8 + ... is represented by the following summation,
Therefore if we continue this pattern, the first 6 terms will be 1 - 2 + 4 - 8 + 16 - 32. Adding these terms,
1 - 2 + 4 - 8 + 16 - 32
= - 1 + 4 - 8 + 16 - 32
= 3 - 8 + 16 - 32 = - 5 + 16 - 32
= 11 - 32 = Solution : - 21

Answer:
4% probability that fazio selects a striped jersey both times.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem:
For each jersey, there are 2+5+3 = 10 possible options, two of which are striped.
So twice 2/10
4% probability that fazio selects a striped jersey both times.
Answer:
The diver will be in free fall for seconds.
Step-by-step explanation:
The distance in feet, that an object falls in t seconds is given by the function .
Now, given that the height is 4800 feet and we have to calculate the number of seconds the diver was in a free fall.
Therefore,
⇒
⇒ seconds.
Therefore, the diver will be in free fall for seconds. (Answer)
