Answer:
28
Step-by-step explanation:
We know that,
A perfect number is a number which is the sum of all of its factors except itself.
Now, as we saw that the first perfect number is 6 because it is the sum of its divisors 1, 2 and 3.
So, we see that the next perfect number is 28.
Now, the divisors of 28 are given by 1, 2, 4, 7, 14 and 28.
Since, 28 = 1 + 2 + 4 + 7 + 14.
i.e. 28 is the sum of all of its divisors except 28 itself.
Thus, 28 is a perfect number.
Hence, the next perfect number is 28.

Answer: 1010</h3>
If your teacher asked you to round to 4 sig figs, then you'd simply say 1005. But your teacher wants 3 sig figs, which means we'll have to round 1005 to some number where that last '5' is a '0'. The rule is trailing zeros, or zeros on the right, are not significant.
For example, the numbers 5700 and 5,700,000 both have the same number of sig figs. Basically they are 57 and then tack on some number of zeros.
Reading the number from left to right has us see 100 as the first three digits. The last digit is 5, which means we round the second to last digit (0) up by 1 going from 100 to 101. Then we replace the 5 with 0.
So 1005 turns into 1010. One way to think of it is to say to yourself "I need to round 1005 to the nearest ten, so I'll go to 1010". You could argue that since 5 is exactly half way between 0 and 10, you could go either direction. Convention usually dictates you round up. I like to think of shopkeepers who round up to make sure they don't lose money when it comes to rounding transaction fees.
With 1010, the first zero is significant while the second zero is not. Therefore the placement of zeros is important. As long as a zero is between two nonzero elements, then that zero is significant.

Step-by-step explanation:
Given that,
Hudson Bay tides vary between and .
Tide is at its lowest when
Completes a full cycle in 14 hours.
To find:- What is the amplitude, period, and midline of a function that would model this periodic phenomenon?
So, The periodic function of this model is
...................(1)
where,
Then putting the value in given Equation(1) we get,
Amplitude =
Now, At it complete full cycle in because it is at lowest at t=0sec.

Answer: Option 'B' is correct.
Step-by-step explanation:
Annual salary of her = $14700
Monthly salary would be
She wants to purchase new things after spending on expenses and save money for her college classes.
According to options :
We can consider Budget B and D as the monthly salary is correct in these budgets only, i.e. $1225.
In Budget B,
Total money she saved = $400
In Budget D,
Total money she saved = $400
So, Budget B is the best which helping meet her goals.
Hence, Option 'B' is correct.
