Answer:

27, 38, and 51

Step-by-step explanation:

3, 6, 11, 18, ...

We increase the first number by 3. Then 5. Then 7.

The pattern is that the difference increases by 2.

That means this is a quadratic sequence.

y = x² + 2, where x = 1, 2, 3, etc.

The next three numbers are 27, 38, and 51.

There are a total of 96 children in Years 4, 5 and 6

BaLLatris [955]

Answer: 20 children

Step-by-step explanation:

Given

Year 4: 11 cannot swim

Year 5: 21 can swim

Year 6: 18 of 30 can swim

Total 96 children

Total 37 cannot swim

First Step: find the number of people from year 5 who cannot swim

There are 30-18=12 people who cannot swim in year 6
There are 11 who cannot swim in year 4
Thus, we use the total number [37]-[year 4+year 6]=37-23=14 people who cannot swim in the year 5

Second Step: find the number of children in year 5

There are 21 children who can swim
There are 14 children who cannot swim
21+14=35 children

Third Step: find the number of children in year 4 who can swim

There are 30 children in year 6
There are 35 children in year 5
There are 11 children in year 4 who cannot swim
There are in total 96 children
96-30-35-11=20 children in year 4 who can swim

Hope this helps!! :)

1=10^0 into logarithmic form

Tatiana [17]

Answer:

$0 = log_{10} 1$

Step-by-step explanation:

Base for the exponent and for the logarithm are the same!

10^0 is the exponential form where 10 is the base and 0 the exponent

$log_{10} 1$ is the logarithm form where 10 is the base

To solve $log_{10} 1 =$ ask the question :

To what power should I raise the base 10 to obtain the number 1 ?

The answer to the power 0 therefore

$log_{10} 1 = 0$

$1 = 10^{0} -is-the- exponential -form\\0 = log_{10} 1 - is -the -logarithmic -form$
