The sum will be prime if its 2, 3, 5, 7, 9, 11, or 13

0+2=2

1+2=3

5+2=7

9+2=11

0+3=3

1+4=5

9+4=13

0+7=7

That's 8 combinations, and there 4*4=16 total.

8/16 = 1/2.

What number gives a result of −5 when 9 is subtracted from the quotient of the number and 6?

My name is Ann [436]

Answer:

Step-by-step explanation:

If it gives a result of -4 then our equation will have .... = -4

If we subtract 9 from the quotient of a number and 5 we have x/5 - 9

Our equation is:

x/5 - 9 = -4 add 9 to both sides

x/5 = -4 + 9

x/5 = 5 multiply both sides by 5

x = 5(5)

x = 25

Check: 25/5 - 9 = 5-9 = -4

Can anyone help me about question 2

Answer:

3(4/3)^2543

Step-by-step explanation:

Using logarithms base 2, we have ...

$(a_n)^{\log{a_n}}=(a_{n+1})^{\log{a_{n-1}}}\\\\(\log{a_n})(\log{a_n}) = (\log{a_{n-1}})(\log{a_{n+1}}) \\\\ \dfrac{\log{a_{n+1}}}{\log{a_{n}}}=\dfrac{\log{a_n}}{\log{a_{n-1}}}=\dots\dfrac{\log_2{16}}{\log_2{8}}=\dfrac{4}{3}$

That is, the ratio of each term to the previous is a constant equal to 4/3. This is the definition of a geometric sequence. This sequence has first term 3 and common ratio 4/3, so the general term is ...

$\log_2 a_n=3\left(\dfrac{4}{3}\right)^{n-1}$
