Answer:
a. The number of people that receive the text in the fourth round are 10³ people
b. The total number of people that receive the text are 1.1111 × 10⁴ people
Step-by-step explanation:
a. The given information are;
The number of people the text is sent to in the first round = 1
In the second round, the number of people the text is sent to by people in the first round = 10
In the third round, the number people the text is sent to by the 10 people in the second round = 10 × 10 = 100 people = 10² people
In the fourth round, the number of people the text is sent to by the people in the third round = 100 × 10 = 1000 people = 10³ people
The number of people that receive the text in the fourth round = 10³ people
b. In the fifth round, the number of people, the people in the fourth round send the text to = 1000 × 10 = 10000 people = 10⁴ people
The total number of people that receive the text = 1 + 10 + 10² + 10³ + 10⁴ people = 11111 people = 1.1111 × 10⁴ people
Answer:
Yes
Step-by-step explanation:
If the longest side squared is equal to the sum of the squares on the other 2 sides then they form a right triangle
longest side = 7.5
7.5² = 56.25
2.1² + 7.2² = 4.41 + 51.84 = 56.25
Thus the 3 values form a right triangle.
It would be china because true and false
