How many 2-digit numbers are multiples of either 5 or 7?
Svet_ta [14]

Answer:

46

Step-by-step explanation:

he count of numbers from 1 to n that are divisible by k is integer part of (n/k).

So the numbers from 1 to 99 divisible by 3 is int(99/3) = 33

Those divisible by 5: int(99/5) = 19

From the sum of those two, subtract those divisible by 15 = int(99/15) = 6

That gives you 33+19-6 = 46.

Now subtract the 1 digit numbers: 3, 5, 6, 9, or four of them

46 - 4 = 42 is the answer.

HELP!Please solve! this!!
Angelina_Jolie [31]

Answer:

Recursive formula for geometric sequence

a_{n}=a_{n-1}\times r

is a_{n}=a_{n-1}\times 6

and explicit formula for geometric sequence a_{n}=a_{1}^{r-1} is

a_{n}=(\frac{1}{2})^{6-1}

Step-by-step explanation:

Given sequence is \frac{1}{2},3,18,108,648,...

To find the recursive and explicit formula for this sequence:

Let a_{1}=\frac{1}{2},a_{2}=3,a_{3}=18,a_{4}=108,a_{5}=648,...

To find the common ratio r:

r=\frac{a_{2}}{a_{1}}

=\frac{3}{\frac{1}{2}}

=3\times 2

=6

Therefore r=6

r=\frac{a_{3}}{a_{2}}

=\frac{18}{3}

=6

Therefore r=6

Therefore the common ration r=6

Therefore the given sequence is geometric sequence

Recursive formula for geometric sequence is a_{n}=a_{n-1}\times r

a_{n}=a_{n-1}\times 6

and explicit formula is a_{n}=a_{1}^{r-1}

a_{n}=(\frac{1}{2})^{6-1}

=(\frac{1}{2})^{5}

=\frac{1}{32}

Therefore a_{n}=\frac{1}{32}
