In mathematics, an irrational number is a number that can not be expressed as a fraction m / n, where m and n are integers and n is different from zero.
For example, the number π is an irrational number.
We must find an irrational number between 5 and 7.
We then have the following number:
Answer:
An irrational number between 5 and 7 is:
Answer:
y = 13
Step-by-step explanation:
An exponential function has the form
y = a
To find a and b use the given points
Using (0, 13), then
13 = a , since
= 1, then
a = 13, thus
y = 13
using (2, 325) , then
325 = 13 b² ( divide both sides by 13 )
25 = b² ( take the square root of both sides )
5 = b
y = 13 × ← is the exponential function
