Biology
1 answer:
timofeeve [1]3 years ago

Answer:

pH=2.9

Explanation:

Hello,

In this case, the pH is computed by:

pH=-log([H^+])

Whereas the concentration of hydrogen ions equals the concentration of the acid for strong acids such as hydrochloric acid (HCl) due to its complete ionization in solution, which means that such concentration is 0.00125 M. Thus, the pH turns out:

pH=-log(0.00125)\\\\pH=2.9

Regards.

Create an explicit equation for each recursively-defined sequence below.
lbvjy [14]

Answer:

  t(n) = 3·5^(n-1)

Explanation:

The recursive formula describes a sequence in which each term is 5 times the one before it. This is a geometric sequence with common ratio 5 and a first term that is said to be 3.

As you know, the generic formula for a geometric sequence is ...

  an = a1·r^(n-1)

For a1 = 3, r = 5, and a sequence named "t", this is ...

  t(n) = 3·5^(n-1)
